That is the definition of ‘encyclopaedic knowledge’… I am no technician, and not a classic car aficionado, but a love this channel, because it is just a joy to listen to this guy . He’s humble, humorous and very eloquent. Great teacher!
This is why Mr Tyrrell’s is by far my favorite viewing on the internet. He has the vehicle in the shop, tells why it’s there, gives the historical significance and where they were headed. I’m not even a Porsche enthusiast, but I certainly appreciate this model more because of went into it. Thank you for sharing Mr Tyrrell.
I fell in love with Porsche as a child. My wonderful stepfather worked for a beer distributor. He started as a deliverer and worked his butt off and became the General Manager of Northeast Sales and Delivery. Finally retired and now makes about the same consulting for them. Anyways he used to take us to Road Atlanta from '75 on. Porsche was sometimes there racing. Amazing the experiences we all have. I fell in love with Porsche at about 6 years old.
Ledwinka was Porsche's student while both lived in Vienna. Porsche was senior to Ledwinka. The intellectual property theft case was dismissed in court, Porsche compensated the Ledwinka family for the platform chassis using a central backbone tube however.
Iain. The more l watch you at work , the more l'm absolutely convinced of your total unassuming prescence. You never boast of your abilities, you just educate us . And we are all willing students , hanging on to your every word . And anxiously awaiting the inevitable "test drive" ! Without doubt the very best motoring programme anywhere ! Thanks Iain.
It is refreshing having a (dare I say) a true mechanic behind the wheel , I'm a mechanic in a different field and you made me feel like I was behind the wheel. You also could be one hell of a salesman makes you want to mortgage the children .
I've been checking the channel for a new episode for several days and here it is. Anyone else find themselves re-watching old episodes when you wishing there was a new one?
Ah the joy of analog mechanicals 😂👍 Great presentation Iain. Your dialog delivery is so clean, accurate, no negative additude. Your plugs are a golden brown. Not to lean, and not to fat. Just crisp.✌️🇬🇧 Retired MB & BMW master Tech from New Hampshire 🇺🇲✌️
Iain - I think this is first Tyrrell’s Garage video I’ve seen discussing Porsches - I’ve thoroughly enjoyed! Porsche mechanics are a distinct breed - one has to think in Porsche engineering terms to really master these cars. Your Porsche mind and skill set is clearly very highly advanced. Thank you for your research on the VW bug’s genesis, I hadn’t been aware of Hans Ledfinka. Also thank you for the detail of the differences between the 2.7RS and its later cousin. I now an custodian of a ‘90 911-964. I came to the 964 after a ‘70 914. Although the 964 is far more competent than the 914, the 914 offered a wonderfully visceral driving experience. I can only imagine how much more visceral the 2.7RS must feel. Thank you for sharing the experience with us. More Porsche content - please!
Much of the slop in the shifting is fixed with replacing the bushings in the little U joint in the selector shaft going into the transmission. In the U.S. the 2.7 has a bad reputation for the case studs pulling out of the block, something easily remedied by properly installing thread inserts in the cases during a rebuild, but too many people still don't like that. Makes an original 2.7 a little cheaper maybe, and also those suffered from our emissions laws. I spent a couple years at a shop that specialized in exotics and the owner spent a lot of years with Porsche and built a large customer base. I really fell in love with the 911, being as most of my work had been in motorcycles I really found the cars easy to work on and had no problem doing heavier work on engines and transmissions, work a lot of mechanics shy from. Pretty much all of the complaints I've heard about their handling and especially with the 930's reputation of being uncontrollable were just dumb rumors, those cars are a joy to drive. A major reason the 911 is held so highly in the sports car world is it's very drivable and reliable, it's also pretty easy to care for, and having been in production for so long there's still excellent support for them. Also there's a huge knowledge base from years of working on, driving, racing and tuning so anything that comes up is usually easy to find a repair or modification for. About the only thing I really don't like about the 911 now is the prices people want for them! They're getting to an age people also don't want to drive them, instead just have it in their collection rotting away.
The unfortunate tendency of wealthy people to buy & store rare special cars is a direct consequence of governments and central banks money issuance policies. The wealthy realise that another systemic bank failure is as nailed on as is WHO pretending there’s another “pandemic”.
I hope you do a video on the Ferrari 308 GT4 which has always been one of my favorite designs from that era. It's proportions are timeless and so under-appreciated. A little cab-forward almost, which you never saw back then. It was the first (I think) that Bertone worked on and its still a stunning car even today. I just saw one yesterday and was tempted to follow it just to meet and talk with the owner. It's so rare to see one and ever more rare to have anyone profile it on RUclips.
Story about Ledwinka in the ball park, (Volkswagen settled lawsuit after the War), but Ledwinka wasn't the founder of air cooled rear engined cars, (he was the inventor of the tubular backbone chassis with independent suspension, and a pioneer in aerodynamics in production cars) but it was actually Ledwinka and Porsche professor - both Austrian and both studied together - that had the rear, air cooled engine as the logical layout (which by many accounts it is, NVH, cooling, packaging etc). Ledwinka was the first to develop the concept commercially, and Hitler - who met Ledwinka several times - raised the copycat question to Porche, which answered that they both looked over each others shoulders (they actually also studied with Carlo Abarth.) Porsche was a great engineer in his own right, the Cisitalia 4WD as an example, but one could argue that Ledwinka was more visionary in certain aspects. Tatra T-77 was WAY ahead of its time, but as the airships... Didn't really catch on. Well, Volkswagen settled for 1.000.000 Deutche Franks after the war. But Tatra was alone developing their version of the concept, so they basically just put new bodywork on the T-77 all the way into the 1990's! Porsche of cource fared better with the 911, and all though Tatra today is a great truck brand, wouldnt it be cool if they made a rear engined V8 Panamera competitor?
Didn‘t Porsche steal the rear-engine concept from Bela Bareynij ( however his sirname is spelled) who has sketched this concept already back in the 1920s?… Also, Bareyjni (?) won a lawsuit against Volkswagen in the 1950s. Béla Barényi is the correct spelling of the Hungarian inventor.
I would disagree with the statement about Tatra after war: The T87 had V8 engine with block caseted out of Electron (quite dificult metal to work with). The first new post-war Tatra, T600 had completely different engine - boxer four cylinder. The T603 enigine was perhaps a relative of the three liter found in T87, however it was 2,5l and I belive aluminum. The 613 had completely different engine to the 603 and this engine was placed directly above the rear axle with gearbox in front of it, shifting the centre of gravity forward (and little up). I agree that it is a poor show to engineer only three cars in a span of fourty years, but suggesting the company limped on with basically pre-war tech up until 90s would be painting very inacurate picture indeed.
One thing worth a mention in that generation of 911 is the visibility. As with several the cars of that time, the A pillars are quite thin, resulting in an excellent view out. 100% agree on the steering too- it’s amazing.
I've taken coworkers for rides in my SAAB 900T to show them why the Corvettes and Camaros we work on every day don't thrill me. Visibility is one of the first points. It's so very important. Once you can see around you it's hard to sacrifice any view (or in the case of those Chevys, MOST of the view lol).
35 minutes gone in like felt like a second. The quality of this channel as whole is simply much higher than most others; one always learns something new and valuable from Mr. Tyrrell. About the 2.7, is one of my hero cars because of that purity that takes the “driver’s car”mantra to a whole new level by throwing anything that hinders experiencing the raw performance this thing is capable of and that soundtrack is glorious. Many thanks to the owner of this faveolus beast for letting it be featured in this video and for driving it often.
Love this video Iain. If professional teachers/lecturers had your ability to educate, the education system in Australia would be much improved. I heartily concur with your views on weight and handling and required power. As a previous owner of an Alfa 105 2.0 GTV and a 3.2 G series 911, neither quick cars by today's standards, but wonderful to drive demonstrate the point, now lost with moderns. Iain's description of steering feel is spot on, both my cars had the "dance across the road feel", so that at all times you knew what the car was doing and how it was reacting to the road conditions and the way it was being driven. Finally your comments about the 911 handling rang true for me, as much as it was slow in, accelerate out, I never had enough confidence in my driving ability with the 911 to push too hard without ending up "inspecting the scenery"
I really appreciate you starting with the story of air-cooled rear-wheel driven cars! There are probably not many who are familiar with the history of Tatra.
Also check out Josef Ganz thers a couple of books where Tatra and Ganz went at logger heads. I spoke to Paul Schilperoord who has most of the archive emails me details patents for the Ganz swing axels and a Tatra equivalent. As well as loads of detailed Ardie chassis prototype photos and Maybug prototype. There are photos of the porsches riding in the Maybug prototype. Being Jewish Ganz has been written out of history as well as work for Mercedes 170 130 rear engined models. Like Porsche Josef was also design consultant. Below the maybug prototype still survives with swung axels rear engine. ruclips.net/video/OjTfqDgZbHU/видео.html
So in essence it's not ledwinka Josef Ganz. No mention of Josef in this video no surprise. As mentioned there are photos of the Porsches sitting in the may bug prototype.
@@gustavoflorio5383 Ferry Porsche and Adolf Rosenberg are photographed sitting in the May bug. Porsche signed a contract to develop the prototype type 12 for NSU Zündapp 1931.
I have been into Tatra and VW since I was seven. Owned a few beetles currently recommissioning a 73 412 estate. Driven to Hessich and Bad Camberg for the Vintage VW Treffens in my old 56 Beetle 2007 and 2009. In my 20s then 37 now.
You are soooo right Mr. Tyrrell describing the pleasure of driving those classic cars ! No need to have 500-600 hp missiles like today's automobiles with absolutely no feed back from the engine and chassis ( not even mentioning fake engine sounds over the radio...)...These classics are pure mechanical enjoyment...Thank you for keeping them alive. What a GREAT video !
Really good episode, Iain. Thank you. I spent most of my teens in the 1960s in what was then West Germany. There was a small group of us in our area, sons and daughters of British army officers, who hung out together, formed relationships (I married the most beautiful of all the girls), and kept our relationships going into our mid to late 20s. Some of us integrated more than others with German society. One of the guys used that to get a great job with Porsche UK, supporting the Porsche team on the RAC Rally. He was issued with a 2.4 or 2.7 911 rally-spec car of the same vintage as the RS that Iain's playing with. He came to visit us in London one day and took us for a drive. Very fast. Very noisy. Absolutely wonderful. Triumph Spitfires had a similar problem as the Porsches of that time. They were more or less OK unless you increased their power. One of my cousins had one and almost doubled the power. He discovered that you couldn't takes liberties at high speed. The outside rear wheel would fold under, lose traction and do a few little hops as it sent you off into the scenery. He got disoriented late at night by a car that appeared to be on the wrong side of the road, jinked left and then right, and went backwards through a hedge and across a ploughed field.
I have to say, I watch many youtubers but your soundclips of an engine revving are the best sounding by far. Maybe the others only capture the exhaust or don't rev it properly
Most just do a (stupid) revving without gear thus no load for the engine and the engine doesn't deliver anywhere near true full power. Ian drives. (There's a reason many modern cars limit max rpm without a load, it's not good for the engines - they need the resistance.)
You have to consider tire technology at the time. Not only Porsche did use rear engine layouts, but also the very successfull Alpine A110. Because of their weight distribution they could accelerate rather quickly out of tight corners, which was really handsome if you consider the roads at the time, especially in Europe - and all the famous Rallyes they won, like Monte Carlo, Mille Miglia, etc.
Le Mans, Targa Florio, Daytona, Paris -Dakar. Only 2nd in the Safari....add Abarth to the list of rear-engined cars, pñus saloons like R8 Gordini, NSU TTS, Simca Rallye and Hillman Imp. There wete also major packaging advantages, and 911 was and is a 2+2, not feasible with a mid-engined car in early 60s.
One of the best car videos on RUclips. So much fascinating information, very enjoyable. This channel is a privileged opportunity to bask in the expertise and experience of someone who understands cars better than anyone else on the internet.
Thank you Iain for sharing your wide ranging knowledge & technical expertise on this ultra rare Porsche 911 Carrera 2.7 RS. Being a former Porsche owner, I was hoping you would have one of their cars in your workshop, & what a model to showcase. One of my all time favourite cars, I have never seen one , so your YT review is the closest I will probably get, & it doesn't diappoint! Keep up the great work 👍
Personally, I wouldn't mind the running length of this episode being doubled, love always loved the styling of the RS and now love it more. Beautiful episode
"Less for more"... I think that's been Porsche's ethos ever since!!! Many thanks for this - had a long day at work and this is the perfect unwind material. Always interesting, enthusiastic and knowledgeable - a real treat!
The 3.2 Carrera CS did cost the same as the base Carrera. So less for the same. Didn‘t sell that good… seems to be that Porsche HAS to overcharge for them to be marketable.
I could have bought one of these for around GBP15k back in in the mid-1990s. The guy that now owns that same car has declined offers of over GBP700k for it recently. Doh! And I hear you on the early turbos. I spent a terrifying day behind the wheel of one on some amazing roads, where I think I nailed about one corner in twenty. I’d go from embarrassingly slow and thinking “you could have gone so much faster” to attempting to be quicker the next corner only to have the turbo spool at exactly the wrong time, and trying to balance immediate plough understeer or backwards into the scenery lift off oversteer with a power delivery that was like an on/off switch. If you were very talented I’m sure it would have been quick, but it scared the crap out me. It wasn’t nice or fun. The 2.7 RS however, was truly sublime and the steering was the best I’ve ever encountered on any car I’ve ever driven (which includes a few open wheelers!). Gawd I wish I’d pushed the boat out and bought it!
Fantastic video. What always gets me in Iain's videos is the background: Breathtaking array of other classics in various states of fettling. You find yourself freezing the frame and backtracking to see if that glimpse was a BMW CSi/CSL, Lamborghini 400 up on the hoist in its original Blue, Espada, Ferarri's...I could go on, but as always, informative particularly regarding Air-cooled history. His comments re Tatra and the origins of air-cooled engineering are enlightening and might rub with the elitists.
As a young teen I had a scrapbook full of stickers, but the last few pages were a shrine to the 911 Turbo. Glued in was an article featuring the whale-tailed beast (pilfered from the car section of one of my dad's Mayfair mags) that made me fall in love. 40 odd years later I still have it today. As usual, you have taught me so much about one of my favourite childhood cars. Great job, Iain.
One of the best presentations ever!!!! To see someone of such knowledge as Iain smile like that at the wheel of a car, you just known his hands are guiding something of extreme joy. Thanks Iain Cheers, Bob
I am becoming a fan of your workshop videos, Iain! This just the third ws I am watching but I am already loving them! Clear technical information combined with marvelous workshork craftmanship, splendid camera shots and the impression that you kind of live the passion you are tranferring! Great, just great! Thanks a lot !
With the imminent arrival of 'Strictly come dancing' coming to our screen's, thank god for people like you producing these great factual compilations for us all to enjoy. Its a Ten from Len. Wonderful viewing. Thank you.
The linkage problem is not in the shifter but the shift rod coupling under the removable plate in the middle of the rear floorboard. Just in front of the rear seats. It's a T-shaped coupling with two nylon bushings that connects the shift linkage rod (and keeps horizontal movement of the shifter precise) with the linkage of the transaxle. You can rebuild it or buy a new coupling. Ferdinand Porsche designed the Mercedes SS and SSK along with the Auto Union Types A-C GP racers (the first mid engined GP cars), and was around for several rear engined Mercedes VW Beetlesque concepts like the Mercedes 130. So the Beetle was small potatos in the engineering genius of Ferdinand Porsche.
@@davidepperson2376 Joseph Cyril Bamford, they invented the tractor with back hoe and front loader I think, really famous in the UK Ireland and I’m sure in Europe to
Props to the owner still using it and enjoying the car. That same trick works on most Bosch mechanical injection units. I had an old International 724 tractor that ran much better with a few more ticks and adjustment of the spring for the governor, haha.
Virtuoso stuff from Ian T, on all levels. Brilliant video. I'll never own a 911 but it did make me get my '83 Le Mans out winter storage. Not a bad substitute....
Great video! My mom is from Czechoslovakia. She told me that Tatra invented the air cooled engines because antifreeze was not really effective for a water cooled engine and they had very harsh winters like Germany. I like your comment in the video about a four-wheel motorcycle, I have one of the originals from the mid-80s. I feel like I'm in a 356 driving around in my property! Cheers from the Finger Lakes & Watkins Glen!
This is just pure gold here, as in any other of his videos, given away by Iain to all of those who know to appreciate it! Thank you so much, and do keep it up!!!
I had several 3.2 Carreras . They used to let go and scare they crap out of me on a regular basis. Loved them tho and managed to keep them on the black stuff. Great motorway car. 100-120mph all day long where you could ..agree about the steering. Original Lotus Elan similar feedback and more delicate tho thanks to skinny tyres. Great review as usual! Thanks Ian!
Brilliant, brilliant stuff, Mr Tyrrell. Thank you once again for sharing your vast historic knowledge of motorsport and the great marques with all of us. Nothing tops this wonderful channel!
I remember back in 1975 as a passenger in my dads Capri 1600 GTXLR , one of these was in front of us at the lights and it just took off , I still recall my dad saying , watch him go . The 911s was a quick car though , genuine 150 mph car . Brilliant vid , thanks so much.
Great video, thanks. On the topic of the rear suspension discussed around 6 min.,; I believe it was not so much the camber change, but the lift-off toe-out behavior of it, that made the rear step out so violently. At least, that’s what I remember my research suggested way back, when after spinning my own ‘78 SC 🙃 A power-on slide was ok, provided you kept your foot down. Which of course is not always possible, so best avoid it altogether and leave those antics to the professionals.
Hans Ledwinka has been mentioned with good reason. Old Tatra passenger cars are magnificent and gorgeous. Just look at the 603. Not to mention the revolutionary engineering their truck department has ever been famous for. Béla Barényi should also be mentioned as somebody who heavily influenced Porsche's Beetle design. He later went on to be a pioneer of safety technology at Mercedes.
Wow that brought back memories..I had no idea about the development of this model. In 1972 I was working for a construction company in Docaster. One day the owner, who knew I loved cars, asked me if I would like to join him to look at his next considered purchase. We met a very dapper young man in Bawtry who had driven up from London in the car and yes it was a 1972 Porsche
Your videos are always a great joy, Ian and I thank you for them. Shame about your passion for Lambos, but we can't have it all ways! Had several 911s through the hands in the '70s and two things still impress, even after all this time--there's nowt like the sound of an air-cooled flat 6 on song, and the steering, which one motor-noter described best as the wheel 'writhing' in one's hands, which I thought an excellent description. Never had a 2.7RS, but did supply, through Hexagon, a 930 Turbo, which I wasn't all that keen on after a certain incident in Hyde Park Corner one wet night.....As you say, the turbo was never a good timekeeper and was always late on parade. They came new with a gallon can of Shell Rotella oil on the back seat, just in case.
I liked the special tool segment. When the British Army was using Lee Enfield based sniper rifles, the armourers would occasionally have difficulty aligning a replacement barrel within acceptable tolerance for collimating the sighting telescope which was carried in a cast iron mount. The first solution was to try different barrels. The second solution was not mentioned in the ‘instructions’ but reportedly always worked. The words ‘hit the mount with a ball pein hammer’ are not written in the standard reference on the Rifle No. 4 Mk 1 (T) but the author’s inference is clear.
LOVED THIS VIDEO! In the early '80s, I had a 1976 Carrera 3.0 and a 1978 SC Sport which I loved and bought and sold for £8K and £11K respectively. Had to sell the SC Sport when the kids started arriving and have never really got over it. Ever since the kids flew the nest, I've been trying to afford a good '80s 911 but it's tough.
I love the way, how Tyrrell demystify things...especially funny for people, who have not the ability to understanding of mechanical mysteries like him (what means: almost everybody)
I’ve already watched this highly interesting video a couple of times along with many others of this outstanding channel. Thank you for your great work, Mr Tyrrell!
Another excellent video. Finally a Porsche 911. I’m not a big fan of the dumbbell analogy. As you said, on one hand an engine and on the other a battery. Hardly a fair balance. But because the front is light, it offers exceptional steering feeling and feedback. Also having the engine in the back does offer some advantages. Such as in traction and braking. Yes, the handling is tricky at the limit and it does not suffer fools. But if properly mastered it’s a winner. As Vic Elford, Walter Röhrl, Peter Gregg and many others have aptly demonstrated. The tricky suspension was later tamed with the Weissach axle. The boxer flat 6 engine itself also offers many advantages. It has a low center of gravity, which is desirable for racing. It has no primary or secondary imbalance, which is great for endurance racing. It has a superior power to weight ratio, because there is no need for heavy radiators and a water jacket around the engine. And because the engine is directly connected to a transaxle and from there to the wheels, there is a minimum power loss from the engine to the wheels. Add to that the Germanic built quality and reliability and you have the greatest sports car ever made.
Tatra actually sued Porsche for patent infringements over the kdf wagen/VW but the case was resolved by the invasion of Czechoslovakia in 1938-39, perhaps the ultimate example of 'force majeure'. I personally call it the pendulum effect, as the majority of the mass is at the back. The reason for that lovely feelsome steering is that there is so little weight over the front wheels; the downside is that front grip is also very variable depending on acceleration/braking and road contour. Owners back in the day were known to put a hundredweight sack in the front to make things more predictable day-to-day. Current 911 drivers should try and find a '70s or '80s 911 to have a go in: it's a very different experience! I love listening to Ian, expertise and passion combined is always a great recipe!
You nailed it early on, those cars are so motorcycle-like in terms of weight transfer sensitivity. The negative side is infamous, but the positive side is the amazing mid corner adjustability, especially with modern rubber wrapped around those fuchs.
Fantastic Video! Any mention of Nikasil takes me back to the 90's when I worked at a BMW dealer. The early M52 6 cylinder motors really didn't like high sulphur fuel which lead to massive bore wear. Each tech had a month of replacing short motors before then the next Tech took over. Interestingly the USA cars had steel liners. Keep up the good work btw!
Nikasil was, funnily enough, also used by Citroen for the 652cc air-cooled twin fitted to the base Visa models... Definitely at the opposite end of the automobile spectrum :)
Nikasil (an abbreviation of nickel silicon-carbide) is an electroplated composite coating comprising of a nickel matrix holding silicon carbide particles in place (similar to rocks and cement in concrete). ... The Electrosil composite coating has a wear resistance 4 to 10 times that of a cast iron sleeve or chromium bore.
Appreciate the reference to the Tatra, but by that logic we should deride all front engine, rear wheel drive cars as just being rip-offs of the 1895 Panhard. There is credit to be had for making the first commercially successful rear air cooled engine, rear wheel drive car. If it wasn't for Porsche, and by extension VW, nobody would be talking about Hans Ledwinka. Also -- to be a pedantic Porsche owner -- the wheelbase was lengthened in 1969 when the engine was still a 2.0 liter. It was only later that the engines moved to 2.2, 2.4 and beyond. While the 917's engine is a flat 12 (or rather a V12 with a 180 degree bank angle), the 911 engine is a "boxer" engine. So cylinders 1 & 4 (opposite each other) hit TDC at the same time, as do 2 & 5, and 3 & 6.

I just saw one yesterday and was tempted to follow it just to meet and talk with the owner. It's so rare to see one and ever more rare to have anyone profile it on RUclips.
Story about Ledwinka in the ball park, (Volkswagen settled lawsuit after the War), but Ledwinka wasn't the founder of air cooled rear engined cars, (he was the inventor of the tubular backbone chassis with independent suspension, and a pioneer in aerodynamics in production cars) but it was actually Ledwinka and Porsche professor - both Austrian and both studied together - that had the rear, air cooled engine as the logical layout (which by many accounts it is, NVH, cooling, packaging etc). Ledwinka was the first to develop the concept commercially, and Hitler - who met Ledwinka several times - raised the copycat question to Porche, which answered that they both looked over each others shoulders (they actually also studied with Carlo Abarth.) Porsche was a great engineer in his own right, the Cisitalia 4WD as an example, but one could argue that Ledwinka was more visionary in certain aspects. Tatra T-77 was WAY ahead of its time, but as the airships... Didn't really catch on.
Well, Volkswagen settled for 1.000.000 Deutche Franks after the war. But Tatra was alone developing their version of the concept, so they basically just put new bodywork on the T-77 all the way into the 1990's!
Porsche of cource fared better with the 911, and all though Tatra today is a great truck brand, wouldnt it be cool if they made a rear engined V8 Panamera competitor?
Didn‘t Porsche steal the rear-engine concept from Bela Bareynij ( however his sirname is spelled) who has sketched this concept already back in the 1920s?… Also, Bareyjni (?) won a lawsuit against Volkswagen in the 1950s. Béla Barényi is the correct spelling of the Hungarian inventor.
I would disagree with the statement about Tatra after war: The T87 had V8 engine with block caseted out of Electron (quite dificult metal to work with). The first new post-war Tatra, T600 had completely different engine - boxer four cylinder. The T603 enigine was perhaps a relative of the three liter found in T87, however it was 2,5l and I belive aluminum. The 613 had completely different engine to the 603 and this engine was placed directly above the rear axle with gearbox in front of it, shifting the centre of gravity forward (and little up). I agree that it is a poor show to engineer only three cars in a span of fourty years, but suggesting the company limped on with basically pre-war tech up until 90s would be painting very inacurate picture indeed.
love Mr T and his skill set...loooove...thank u...no bull crap just pure car love.
One thing worth a mention in that generation of 911 is the visibility. As with several the cars of that time, the A pillars are quite thin, resulting in an excellent view out. 100% agree on the steering too- it’s amazing.
I've taken coworkers for rides in my SAAB 900T to show them why the Corvettes and Camaros we work on every day don't thrill me. Visibility is one of the first points. It's so very important. Once you can see around you it's hard to sacrifice any view (or in the case of those Chevys, MOST of the view lol).
35 minutes gone in like felt like a second. The quality of this channel as whole is simply much higher than most others; one always learns something new and valuable from Mr. Tyrrell.
About the 2.7, is one of my hero cars because of that purity that takes the “driver’s car”mantra to a whole new level by throwing anything that hinders experiencing the raw performance this thing is capable of and that soundtrack is glorious. Many thanks to the owner of this faveolus beast for letting it be featured in this video and for driving it often.
As a German I always love how you pronounced these German names of the manufactures. Absolutely brilliant !
Did you listen to it ?

Love this video Iain. If professional teachers/lecturers had your ability to educate, the education system in Australia would be much improved. I heartily concur with your views on weight and handling and required power. As a previous owner of an Alfa 105 2.0 GTV and a 3.2 G series 911, neither quick cars by today's standards, but wonderful to drive demonstrate the point, now lost with moderns. Iain's description of steering feel is spot on, both my cars had the "dance across the road feel", so that at all times you knew what the car was doing and how it was reacting to the road conditions and the way it was being driven. Finally your comments about the 911 handling rang true for me, as much as it was slow in, accelerate out, I never had enough confidence in my driving ability with the 911 to push too hard without ending up "inspecting the scenery"
This has become one of the best car channels on RUclips. Thanks for another wonderful program!
I've been waiting for this video most of my adult life. A comprehensive description of what makes a 911 a 911
I really appreciate you starting with the story of air-cooled rear-wheel driven cars! There are probably not many who are familiar with the history of Tatra.
Also check out Josef Ganz thers a couple of books where Tatra and Ganz went at logger heads.
I spoke to Paul Schilperoord who has most of the archive emails me details patents for the Ganz swing axels and a Tatra equivalent. As well as loads of detailed Ardie chassis prototype photos and Maybug prototype. There are photos of the porsches riding in the Maybug prototype.
Being Jewish Ganz has been written out of history as well as work for Mercedes 170 130 rear engined models. Like Porsche Josef was also design consultant.
Below the maybug prototype still survives with swung axels rear engine.

@@gustavoflorio5383 Ferry Porsche and Adolf Rosenberg are photographed sitting in the May bug. Porsche signed a contract to develop the prototype type 12 for NSU Zündapp 1931.
I have been into Tatra and VW since I was seven. Owned a few beetles currently recommissioning a 73 412 estate. Driven to Hessich and Bad Camberg for the Vintage VW Treffens in my old 56 Beetle 2007 and 2009. In my 20s then 37 now.
You are soooo right Mr. Tyrrell describing the pleasure of driving those classic cars ! No need to have 500-600 hp missiles like today's automobiles with absolutely no feed back from the engine and chassis ( not even mentioning fake engine sounds over the radio...)...These classics are pure mechanical enjoyment...Thank you for keeping them alive. What a GREAT video !
You are such a wealth of information and present that information impeccably. Appreciate it!
Really good episode, Iain. Thank you.
I spent most of my teens in the 1960s in what was then West Germany. There was a small group of us in our area, sons and daughters of British army officers, who hung out together, formed relationships (I married the most beautiful of all the girls), and kept our relationships going into our mid to late 20s. Some of us integrated more than others with German society. One of the guys used that to get a great job with Porsche UK, supporting the Porsche team on the RAC Rally. He was issued with a 2.4 or 2.7 911 rally-spec car of the same vintage as the RS that Iain's playing with. He came to visit us in London one day and took us for a drive. Very fast. Very noisy. Absolutely wonderful.
Triumph Spitfires had a similar problem as the Porsches of that time. They were more or less OK unless you increased their power. One of my cousins had one and almost doubled the power. He discovered that you couldn't takes liberties at high speed. The outside rear wheel would fold under, lose traction and do a few little hops as it sent you off into the scenery. He got disoriented late at night by a car that appeared to be on the wrong side of the road, jinked left and then right, and went backwards through a hedge and across a ploughed field.
I have to say, I watch many youtubers but your soundclips of an engine revving are the best sounding by far. Maybe the others only capture the exhaust or don't rev it properly
Most just do a (stupid) revving without gear thus no load for the engine and the engine doesn't deliver anywhere near true full power.
Ian drives.
(There's a reason many modern cars limit max rpm without a load, it's not good for the engines - they need the resistance.)
Possibly the best video from what is now the best car channel. Bravo.
You have to consider tire technology at the time. Not only Porsche did use rear engine layouts, but also the very successfull Alpine A110.
Because of their weight distribution they could accelerate rather quickly out of tight corners, which was really handsome if you consider the roads at the time, especially in Europe - and all the famous Rallyes they won, like Monte Carlo, Mille Miglia, etc.
Le Mans, Targa Florio, Daytona, Paris -Dakar. Only 2nd in the Safari....add Abarth to the list of rear-engined cars, pñus saloons like R8 Gordini, NSU TTS, Simca Rallye and Hillman Imp. There wete also major packaging advantages, and 911 was and is a 2+2, not feasible with a mid-engined car in early 60s.
Iain is such a an amazing gentleman. When I grow up I want to be half the man he is.
Then you would only be 3 feet tall 😂😂😂👌👌👌
One of the best car videos on RUclips. So much fascinating information, very enjoyable.
This channel is a privileged opportunity to bask in the expertise and experience of someone who understands cars better than anyone else on the internet.
Thank you Iain for sharing your wide ranging knowledge & technical expertise on this ultra rare Porsche 911 Carrera 2.7 RS. Being a former Porsche owner, I was hoping you would have one of their cars in your workshop, & what a model to showcase. One of my all time favourite cars, I have never seen one , so your YT review is the closest I will probably get, & it doesn't diappoint! Keep up the great work 👍
Wow. One of the best Videos i have ever seen. Hands down. I salute you for this.
Personally, I wouldn't mind the running length of this episode being doubled, love always loved the styling of the RS and now love it more. Beautiful episode
Tyrrell have you a way of educating us keen pupils that is fantastic. The back stories you offer on the cars and engineering are wonderful. Thank you.
"Less for more"... I think that's been Porsche's ethos ever since!!!
Many thanks for this - had a long day at work and this is the perfect unwind material. Always interesting, enthusiastic and knowledgeable - a real treat!
The 3.2 Carrera CS did cost the same as the base Carrera. So less for the same. Didn‘t sell that good… seems to be that Porsche HAS to overcharge for them to be marketable.
I've been reading about Carrera 2.7 RSs in books and magazines for decades and still learned new info from this video!
Another masterpiece thanks Ian your knowledge is second to none
Stop brown nosing.
I drove a RHD 72 2.4S HMY3K for years but sold it in 2004. a more modest but delightful 1968 912 took its place and its a peach
Don’t think we have ever seen you smile so much taking a test drive 😁
I could have bought one of these for around GBP15k back in in the mid-1990s. The guy that now owns that same car has declined offers of over GBP700k for it recently. Doh! And I hear you on the early turbos. I spent a terrifying day behind the wheel of one on some amazing roads, where I think I nailed about one corner in twenty. I’d go from embarrassingly slow and thinking “you could have gone so much faster” to attempting to be quicker the next corner only to have the turbo spool at exactly the wrong time, and trying to balance immediate plough understeer or backwards into the scenery lift off oversteer with a power delivery that was like an on/off switch. If you were very talented I’m sure it would have been quick, but it scared the crap out me. It wasn’t nice or fun. The 2.7 RS however, was truly sublime and the steering was the best I’ve ever encountered on any car I’ve ever driven (which includes a few open wheelers!). Gawd I wish I’d pushed the boat out and bought it!
Fantastic video. What always gets me in Iain's videos is the background: Breathtaking array of other classics in various states of fettling. You find yourself freezing the frame and backtracking to see if that glimpse was a BMW CSi/CSL, Lamborghini 400 up on the hoist in its original Blue, Espada, Ferarri's...I could go on, but as always, informative particularly regarding Air-cooled history. His comments re Tatra and the origins of air-cooled engineering are enlightening and might rub with the elitists.
As a young teen I had a scrapbook full of stickers, but the last few pages were a shrine to the 911 Turbo.
Glued in was an article featuring the whale-tailed beast (pilfered from the car section of one of my dad's Mayfair mags) that made me fall in love.
40 odd years later I still have it today.
As usual, you have taught me so much about one of my favourite childhood cars. Great job, Iain.
One of the best classic car videos I've ever seen. Excellent.
One of the best presentations ever!!!! To see someone of such knowledge as Iain smile like that at the wheel of a car, you just known his hands are guiding something of extreme joy.
Thanks Iain
Cheers, Bob
I am becoming a fan of your workshop videos, Iain! This just the third ws I am watching but I am already loving them! Clear technical information combined with marvelous workshork craftmanship, splendid camera shots and the impression that you kind of live the passion you are tranferring! Great, just great! Thanks a lot !
Thank you!
With the imminent arrival of 'Strictly come dancing' coming to our screen's, thank god for people like you producing these great factual compilations for us all to enjoy. Its a Ten from Len. Wonderful viewing. Thank you.
Love all the rich details Iain provides.
The linkage problem is not in the shifter but the shift rod coupling under the removable plate in the middle of the rear floorboard. Just in front of the rear seats. It's a T-shaped coupling with two nylon bushings that connects the shift linkage rod (and keeps horizontal movement of the shifter precise) with the linkage of the transaxle. You can rebuild it or buy a new coupling. Ferdinand Porsche designed the Mercedes SS and SSK along with the Auto Union Types A-C GP racers (the first mid engined GP cars), and was around for several rear engined Mercedes VW Beetlesque concepts like the Mercedes 130. So the Beetle was small potatos in the engineering genius of Ferdinand Porsche.
Sensational show like always, so much information in depth, so much concise way to explain, all in high class english, a delight.Many thanks
Is it that I was a child at the time or are the 70s sportscars indeed the absolute peak in the history of automobiles?

Props to the owner still using it and enjoying the car. That same trick works on most Bosch mechanical injection units. I had an old International 724 tractor that ran much better with a few more ticks and adjustment of the spring for the governor, haha.

It's really good to hear about such a superb car not sitting for 364 day a year in a garage or museum but actually doing what it was built to do :-)
If I were a baron, I would do just that. Daily drive this car. SO my question would be, did Porsche have the same nakasil problem that BMW had ?.
I agree 100%, glad to see a car out being driven! get to it!

I love this very in-depth review of these classic cars added to the already brilliant mechanical work on it. Keep them coming Iain!
I don't know alot about cars but this stuff is just amazing
Great video! My mom is from Czechoslovakia. She told me that Tatra invented the air cooled engines because antifreeze was not really effective for a water cooled engine and they had very harsh winters like Germany. I like your comment in the video about a four-wheel motorcycle, I have one of the originals from the mid-80s. I feel like I'm in a 356 driving around in my property! Cheers from the Finger Lakes & Watkins Glen!
@2:35 "Can we please build these?" he says. How polite of that h person.
This is just pure gold here, as in any other of his videos, given away by Iain to all of those who know to appreciate it!
Thank you so much, and do keep it up!!!
1:09 'pay more, get less'...love it, best car videos on RUclips bar none
I had several 3.2 Carreras . They used to let go and scare they crap out of me on a regular basis. Loved them tho and managed to keep them on the black stuff. Great motorway car. 100-120mph all day long where you could ..agree about the steering. Original Lotus Elan similar feedback and more delicate tho thanks to skinny tyres. Great review as usual! Thanks Ian!
Brilliant, brilliant stuff, Mr Tyrrell. Thank you once again for sharing your vast historic knowledge of motorsport and the great marques with all of us. Nothing tops this wonderful channel!
Fascinating as usual. Would have loved to see your gear change work though.
Part of a Sunday now is to watch a Tyrrell classic workshop, fantastic 👍
Another great video Iain. Your channel is one of the best (if not the best) on RUclips. Your knowledge on special cars like this is unmatched.
Amazing video Ian. Thank you so much. As a Porsche lover, this is massively appreciated.
Very nice indeed but I would be more than happy with the "inferior" gold one.
I remember back in 1975 as a passenger in my dads Capri 1600 GTXLR , one of these was in front of us at the lights and it just took off , I still recall my dad saying , watch him go . The 911s was a quick car though , genuine 150 mph car . Brilliant vid , thanks so much.
Very good insight on the 911. I like the rear bias on it. It makes it alive somehow. i never lift at apex, who does?
Love the comments on how to drive a 911. I learned a long time ago about throttle off oversteer !!!
More Porsche content please, that was great, would be interested to know more about the gold '76..?
This is consistently a fantastic show.
Great video, thanks. On the topic of the rear suspension discussed around 6 min.,; I believe it was not so much the camber change, but the lift-off toe-out behavior of it, that made the rear step out so violently. At least, that’s what I remember my research suggested way back, when after spinning my own ‘78 SC 🙃 A power-on slide was ok, provided you kept your foot down. Which of course is not always possible, so best avoid it altogether and leave those antics to the professionals.
I spun my SC also. Terrifying.
Hans Ledwinka has been mentioned with good reason. Old Tatra passenger cars are magnificent and gorgeous. Just look at the 603. Not to mention the revolutionary engineering their truck department has ever been famous for. Béla Barényi should also be mentioned as somebody who heavily influenced Porsche's Beetle design. He later went on to be a pioneer of safety technology at Mercedes.
Wow that brought back memories..I had no idea about the development of this model. In 1972 I was working for a construction company in Docaster. One day the owner, who knew I loved cars, asked me if I would like to join him to look at his next considered purchase. We met a very dapper young man in Bawtry who had driven up from London in the car and yes it was a 1972 Porsche
Fantastic video . Such a privilege to watch a master craftsmen working his magic . Keep them coming please !
Your videos are always a great joy, Ian and I thank you for them. Shame about your passion for Lambos, but we can't have it all ways!
Had several 911s through the hands in the '70s and two things still impress, even after all this time--there's nowt like the sound of an air-cooled flat 6 on song, and the steering, which one motor-noter described best as the wheel 'writhing' in one's hands, which I thought an excellent description.
Never had a 2.7RS, but did supply, through Hexagon, a 930 Turbo, which I wasn't all that keen on after a certain incident in Hyde Park Corner one wet night.....As you say, the turbo was never a good timekeeper and was always late on parade. They came new with a gallon can of Shell Rotella oil on the back seat, just in case.
I liked the special tool segment. When the British Army was using Lee Enfield based sniper rifles, the armourers would occasionally have difficulty aligning a replacement barrel within acceptable tolerance for collimating the sighting telescope which was carried in a cast iron mount. The first solution was to try different barrels. The second solution was not mentioned in the ‘instructions’ but reportedly always worked. The words ‘hit the mount with a ball pein hammer’ are not written in the standard reference on the Rifle No. 4 Mk 1 (T) but the author’s inference is clear.
LOVED THIS VIDEO! In the early '80s, I had a 1976 Carrera 3.0 and a 1978 SC Sport which I loved and bought and sold for £8K and £11K respectively. Had to sell the SC Sport when the kids started arriving and have never really got over it. Ever since the kids flew the nest, I've been trying to afford a good '80s 911 but it's tough.
Priceless expertise and insights - getting across the mechanical facts and intangible magic equally. Brilliantly done.
I love the way, how Tyrrell demystify things...especially funny for people, who have not the ability to understanding of mechanical mysteries like him (what means: almost everybody)
Fantastic Review and Road Test. Thank you very much Ian. 👍
I’ve already watched this highly interesting video a couple of times along with many others of this outstanding channel. Thank you for your great work, Mr Tyrrell!
Thank you!
I should mention I grew up near Weissach, Porsche Development Center 😉@@iain_tyrrell
so articulate about preserving, maintaining and especially how to drivr these wonderful classics
Love that there is almost always an Espada in the background of these videos :-)
Another excellent video. Finally a Porsche 911.
I’m not a big fan of the dumbbell analogy. As you said, on one hand an engine and on the other a battery. Hardly a fair balance. But because the front is light, it offers exceptional steering feeling and feedback. Also having the engine in the back does offer some advantages. Such as in traction and braking. Yes, the handling is tricky at the limit and it does not suffer fools. But if properly mastered it’s a winner. As Vic Elford, Walter Röhrl, Peter Gregg and many others have aptly demonstrated.
The tricky suspension was later tamed with the Weissach axle.
The boxer flat 6 engine itself also offers many advantages. It has a low center of gravity, which is desirable for racing. It has no primary or secondary imbalance, which is great for endurance racing. It has a superior power to weight ratio, because there is no need for heavy radiators and a water jacket around the engine. And because the engine is directly connected to a transaxle and from there to the wheels, there is a minimum power loss from the engine to the wheels. Add to that the Germanic built quality and reliability and you have the greatest sports car ever made.
This is one of my all time favourites for so many reasons - truly superb to see this wonderful example.
Tatra actually sued Porsche for patent infringements over the kdf wagen/VW but the case was resolved by the invasion of Czechoslovakia in 1938-39, perhaps the ultimate example of 'force majeure'.
I personally call it the pendulum effect, as the majority of the mass is at the back. The reason for that lovely feelsome steering is that there is so little weight over the front wheels; the downside is that front grip is also very variable depending on acceleration/braking and road contour. Owners back in the day were known to put a hundredweight sack in the front to make things more predictable day-to-day. Current 911 drivers should try and find a '70s or '80s 911 to have a go in: it's a very different experience!
I love listening to Ian, expertise and passion combined is always a great recipe!
You nailed it early on, those cars are so motorcycle-like in terms of weight transfer sensitivity. The negative side is infamous, but the positive side is the amazing mid corner adjustability, especially with modern rubber wrapped around those fuchs.
I am always in awe of your ability to reach deep into engine bays without ruining your watch
Years of practice! 😊 thx for your interest
Fantastic Video! Any mention of Nikasil takes me back to the 90's when I worked at a BMW dealer. The early M52 6 cylinder motors really didn't like high sulphur fuel which lead to massive bore wear. Each tech had a month of replacing short motors before then the next Tech took over. Interestingly the USA cars had steel liners. Keep up the good work btw!
Nikasil was, funnily enough, also used by Citroen for the 652cc air-cooled twin fitted to the base Visa models... Definitely at the opposite end of the automobile spectrum :)
Who are part of VW group
Moto Guzzi has been using nicasil liners since the mid 70’s. First on the V50.
...and BMW, Mercedes, Jaguar, NSU, Suzuki, etc.
%ñ
Nikasil (an abbreviation of nickel silicon-carbide) is an electroplated composite coating comprising of a nickel matrix holding silicon carbide particles in place (similar to rocks and cement in concrete). ... The Electrosil composite coating has a wear resistance 4 to 10 times that of a cast iron sleeve or chromium bore.
I also used to Tweak those bosch Rotor arms. Saab Turbo 8 valves used to have the very same rotor arm. But set for about 6,100.
Appreciate the reference to the Tatra, but by that logic we should deride all front engine, rear wheel drive cars as just being rip-offs of the 1895 Panhard. There is credit to be had for making the first commercially successful rear air cooled engine, rear wheel drive car. If it wasn't for Porsche, and by extension VW, nobody would be talking about Hans Ledwinka.
Also -- to be a pedantic Porsche owner -- the wheelbase was lengthened in 1969 when the engine was still a 2.0 liter. It was only later that the engines moved to 2.2, 2.4 and beyond. While the 917's engine is a flat 12 (or rather a V12 with a 180 degree bank angle), the 911 engine is a "boxer" engine. So cylinders 1 & 4 (opposite each other) hit TDC at the same time, as do 2 & 5, and 3 & 6.
Nice post.
