The "nerdy" bits are precisely why I love these videos. Four degrees difference in the cam lobes front to back? I have an even greater appreciation for the engineers at Ferrari.
They're inferior to German engineering. Wops make cars that look & sound nice, but never give much care to quality, corrosion resistance, safety, durability, etc.........
Iain, if you want to make a 3-hr video of a Daytona drive, don't let me stop you. I'll watch it and I'm sure many other channel viewers will too. That car is beyond gorgeous and the design is timeless. Ferrari could sell a car with that styling today and it wouldn't look old-fashioned.
As long as it’s Iain who blesses us with a mountain of facts and not a bunch of unrehearsed quirks and features that are more often wrong and lacking fidelity I also would love to see that. I am happy when I learn something new and there’s no better man for that job than Iain Tyrell, that’s for sure.
The extra exhaust pipes are taking part of the flow on a bit longer path. After merging, there is a shift in the pulse timing. Part of the pulse in the straight part is joined by the time shifted pulse. It's making some of the frequencies of the exhaust quieter and some louder. The length and size of the longer tubes make the specific points quieter and louder. It's kind of an intereference that's used in noise canceling headphones, but it also works in a positive way, not just in the negative.
I had a four cylinder Suzuki 1100 with a 4-into-1 extractor exhaust on it. About 10 centimeters from exiting the cylinder head, the pipes were interconected 1 to 2 and 3 to 4 via an external can each. These cans were supposed to increase mid to low-high power.
The ultimate Ferrari as far as I’m concerned, yes a 250 GTO is even more special, but there’s something brutish and yet beautiful about the Daytona that sets it apart. Thanks for making another great video on a car that is utterly iconic!
Every new video from this channel is a genuine treat, but this one gets even better than usual, because the Daytona is my favorite Ferrari of all. A few years ago I had the privilege of spending an afternoon talking cars with the legendary Ingegnere Fioravanti at his villa, here in the Turin area. I was researching the history of the Lancia Gamma (which he designed) for the book I was writing about it, and the great designer was wonderful company, a true gent! It's a memory I'll treasure forever.
Ian, I think you should read this - will probably put some more colours in your paint box! "Super Numery Pipes" - so interesting as this Ferrari feature predates computer flow dynamics! (I have worked for a UK company (you will have worked on their sports cars) who have done computer engine performance modeling/development for Bentley, GM, Ford, Triumph MC, Harley Davidson, Rolls Royce, JCB, Daewoo, KIA, etc, etc.) When the exhaust valve(s) open the mass of gas proceeds down the manifold uniformly until a juncture (pipe join), at this point a low pressure shock wave is generated that travels BACK towards towards the exhaust valves (that have now shut). At certain RPM's this low pressure shock wave will reach the exhaust valve(s) when they are open again for the next cycle, and the low pressure wave will scavenge the cylinder of exhaust and draw in a fresh intake charge (as the valves are on overlap) - enabling the cylinder to produce a lot of power. As the "SNP" join is here at the 3 into 1 junction I expect it enhances the effect - but as it never became a standard feature on performance engines, I expect the complexity/cost outweighed the benefit? If you look at a Ford Kent engine in a Formula Ford single seater racing car, you will see a 4 into 1 exhaust which is tuned for one condition i.e. max power - as these drivers need to keep the engine at this condition to win. However the Ford Kent engine in a rally car, where there is a need of a broader spread of power, you will see an 4 into 2 into 1 exhaust manifold, which will generate THREE times as many reflections benefiting a greater speed range - producing a broader torque range - needed by rally drivers. And how fast does that low pressure reflection wave travel at - it's the speed of sound - but the speed of sound changes relative to the pressure, density and temperature of the medium (i.e. gas or liquid) being considered. Those two stroke motorcycle racers who lagged their exhaust pipes on cold days had already realised this. If you have read this far - big respect - and please give me a thumbs up!!!?
The supernumerary exhaust pipes are likely two different Helmholtz resonators designed to operate at two different frequencies (the front chamber is a different size than the rear) to eliminate drone in the exhaust, especially loud and noisy exhaust systems. Cutting edge in it's day, we now use other methods (cheaper and smaller) to eliminate drone in the exhaust.
Ian, your music producer friend will know how this works! To eliminate a sound frequency (in this instance droning sound) you would take the same frequency and "mix it back in" at the same frequency 180° out of phase, i.e. " noise cancelling" if you remember seeing the old rock bands live, the singer had 2 microphones one at a slight angle, this was not for the singers voice but to pick the band noise up the microphone was wired up in reverse (180° out of phase) and then fed it into the singers monitor mix which cancelled the bands sound that bled in to the singers mic, so that the singer only heard their own voice.
Glorious! The GoPro show of the front wheel and front wing........just need Phil Collins singing In The Air Tonight. Yes, Miami Vice made me fall in love with the Daytona and, yes, I'm aware that was a Corvette in a Ferrari dress, but it at least made me do my Ferrari research. Such an achingly gorgeous design.......and the music that engine makes. Glorious!
I remember an Italian film with Senta Berger driving a red spider in the sea. Alpes and and David Janssen followed her in a second car not sure whether this was a spider or a coupe…from 1972/73..?
Perhaps the reason for the "supernumerary exhaust" is the firing order @ 3.27. That alone suggests to me that some elegant thinking was done to exploit the shock waves in the exhaust to help either scavenging or in cylinder filling where the shock wave is directed back towards the exhaust port/valve to stop fresh mix escaping, usually when there is a more than the usual inlet and exhaust valve/port overlap. This can often be found in the two-stroke engine using expansion chamber exhaust design pioneered by Walter Kaden. It would be fun to dyno-test the output with this exhaust solution against single straight pies for each cylinder...The sound... Thanks. 👍

I am from a small Midwestern town in America and you don't see exotic cars very often. There is a pawn shop near where I live and they had a black Daytona convertible in the window and when I drove by I could not believe it and I went back and looked at it, what a beautiful car. It was the owner of the pawn shop's car and he was just storing it there.
I'm 58. The 365GTB/4 was always my fantasy car!! The CAR magazine test by Mel Nicholls was an obsession. This superb video was tremendously nostalgic.The profile was just perfection (closely followed by a yellow/black 512BB). Bravo Mr. Tyrelll!!!👏👏👏👏👏
Hi Mark. I'm 64 and I think that I've read the same road test as you! It's done the same thing to me 😊. It is my lottery win car, I still have the car magazine with the daytona on the front cover, in or next to a field of ( corn stubble) with the sun rising wow! What an Image! Yep, still wishing I could afford one today. 😊
When I had worked at a classic car shop, I had the privilege to drive a Daytona Spyder that wasnt in Concours condition, but it was a nice car. A driver's car. We had just performed a tune-up, and when I went for a test drive. I instantly fell in love with the car. From how smooth changing gears was to the engine's responsiveness and sewing-machine-like smoothness. When you put your foot down, oh how she went and wanted to keep going too! For this car, the steering did have a little bit of play in it, but nothing that was like driving a truck. I was quite surprised at how light the steering actually was. The previous car I worked on was a Testarossa, and the Daytona took much less effort to drive, including in the parking lot. The suspension was also just splended with how it absorbed the bumps and undulations in the road but you always felt secure, in control of the car. Truly has become one of my most favorite cars. Whenever I do find myself with the money to purchase a Daytona, I will most certainly will without any hesitation
I remember this car fondly as a young buck. Whilst living in Germany, I had many Auto Quadrat? - Trumpf? Card games where the 365 GTB was the card to have. It and the Lamborghini Miura trumped all other cars/cards in the stack…. Cars of the late 60s and 70s was the era of classy/beautiful/sensual/elegant design! What a time it was! Thanks for the memories. Ferrari was the business!
Was lucky to drive for the day an original Daytona convertable in the early 80s. An experience you never forget. We also had an AC Cobra 427 for a day now that was a dangerous thing to drive down Yorkshire narrow country roads. Terrifying but an experience never to forget.
Iain I have to agree, I was twenty something when this car came out with the correct lights. It is still a great car. The induction and exhaust noise is amazing. I remember reading somewhere way back that the additional exhaust pipes created a vacuum ahead of the exhaust gas leading front and acted as a secondary scavenger system.
Thank you very much once again Ian, for the high quality video you posted. Nothing to discard, only the sheer pleasure to share your knowledge and enjoy the beauty of the automotive world.
Lovely video. I’ve always been a massive fan of the Daytona or 365 GTB/4 to use its full name. Without a doubt my most favourite Ferrari. Such a stunning looking car even over half a century later. A masterpiece and so far ahead of it’s time. Full of state of the art design for the late 1960’s. Thank you Iain so much for great in depth video. What a beautiful Daytona.
Thank you for the close up look at the bottom of the beauty 😉 And thank you for taking us along for the ride. I realise it is tedious work freeing up a Daytona suspension. But hey, someone has to do it.
As a young 17 year old I got the prelidge going to Chenitte’s in Greenwich CT to pick up a new exhaust system with a neighbor for his 330 GTC back in 1978. We got a walk around in the basement and saw a Daytona covered in dust with a customers repair invoice with probably almost more than the car was worth. Explains the dust. Stunning car thanks for the memories!
And those "hidden" windshield wipers, what a details on this beautiful car! I know that Iain doesn't like the word iconic, but maybe this is an iconic car......! Thank you for the video, I love it. Let's hope that the owner decides it to leave this Daytona as original as possible!
Iain that note on the paper on the dash read “ don’t forget your top gun sunglasses Iain”. The other surprise on this car is the driving position which looks spot on; no short legs and long arms. It would be good to show people how those wheels are removed- most wont believe it! Great film and full of little Daytona nuggets. Who knew linear power curve to 7700. Almost unheard of on other cars. Porsche didn’t go this route. Nor Jaguar. 5.6 seconds is another world in 1969!
Thanks so much for this Iain. This is my all time favourite car so beautiful and the sound is awesome. I didn't know Alain De Cadenet has passed away such a gentleman, great driver and car enthusiast I loved his Victory By Design series .
Wonderful video Iain brings back memories when as a 16 year old schoolboy I was lucky enough to get a lift by my neighbour in his beautiful Daytona on his way to work. Just a glorious sound and the acceleration was amazing. Been my favourite Ferrari ever since. 😊
The super numary exhaust pipe acts as a by pass for built up gasses that are produced by back pressure. As the exhaust gasses leave the engine they are in free flow until they meet the baffles in the first silencer, these baffles create back pressure. A bit of back pressure is OK but not too much as gasses then can't exit the the cylinders freely. The extra pipes act as a method of releasing some of that unrequired back pressure by allowing some of the gasses to escape the main pipe and enter the silencer by a different route. It's all about control of back pressure.
Wow....i smiled the whole way through this video. As a child in the early 70s I played 'top trump cards' and this was my favourite from, one of the many car type card pack me and my brother played together. To see it so many years later in the flash..well its better then I imagined at the time. Wonderful to see. Thank you very much. Superb ....Cheers
Always loved the Daytona/ 365 GTB. Glorious sound when you open the taps. 1 would be added to a collection if funds allowed, its 1 of the few Classic cars that has never aged.
The Daytona and the Testarossa are my favorite Ferraris. If I ever won the lottery, a big lottery, I would make sure to get these into my garage. Great to see them together. To dream.
Clay Regazzoni owned one and drove it daily In Maranello people used to talk about his legendary commuting 'lap' times on the trips to and from the grand prix locations around Europe. Still to this day. This brings me to think that this car was something else for its time.
The design of the camshaft really impressed me, off setting the rear lobes to allow for the torsion or twisting of the shaft under load is just ridiculous attention to detail.
I was told by the ansa rep, whose products I sold in the 1970s, that the super numery pipes are for harmonic tuning. As such I consider them a great success. One of the best sounding cars I have ever experienced.
That Daytona looks mint. I bought such as Road&Track, read Brock Yates whilst in sixth form. The oil crisis came soon after when values crashed. Setright, also musician, wrote an article on the musical harmonics of the exhaust system.
I remember going to Italy to visit my family in 74 and there was a white Daytona in the building as an 11 year old i was drooling over it every day, beautiful car, you are absolutely tight about a compression leak test, i remember a mercedes 190 tha passed with flying colours a compression test and had a 60% compression leak at tdc.
Great video as usual, Iain. Nice to know that my humble 2.4 Fiat Dino coupe had the same valve timing as a Daytona. Redlined at 8000, although I only ever went up to 7500, the Dino engine always pulled very smoothly low down and gave a noticeable surge as it hit 4000. Great sound too, needless to say!
The value differences of Daytona's today are significantly higher than the original cost differences between the E-Types, Ghibli's and especially the Rolls, so history has proven that the Daytona was worth the extra money.
The first video I ever watched on this channel was a preceding one of the 72 Daytona Spyder convertible. I was introduced to this car via Miami Vice (The authentic one)as I'm sure were many. I continue to like it more than the Testerossa. Over the years I've rarely caught glimpses of them in the media. I know why now. They are scarce. Great to make your acquaintence Tyrell. What your doing is beautiful. I shall look forward to future and catch up on past content.
Iain, I live my exotic car obsession vicariously through you and this channel. I love to see you bring to life and enjoy the classic exotics that you work on. I absolutely love the early Lamborghinis and Ferraris specifically… with the combination of rawness and elegance that they exhibit. I think the Italian styling of that era is beautiful…especially so when contrasted to today, in a world where all the supercars look basically the same (in my opinion). The individuality of the classics is wonderful to see. I personally think that the Lamborghini Miura is the most beautiful car ever built, and I always love when you do an episode on them. You bring them (the cars) to life in your workshop for the enjoyment and pleasure of all of us who likely will never get to personally experience them. Thank you!
I love the info on the valve timing on the V12 and V6 being similar giving the lovely linear power curve. I was given a spirited ride in a 246 Dino when I was 17 and have loved the V6 ever since.
Another excellent review by Iain. He is always entertaining and educating. A great piece on the Daytona. I’ve got a 575M..like Iain said, nothing drives like a front engined V12 with rear gearbox.
Really fantastic video, so many interesting details, does justice to the original design and intent of the engineers who created these beautiful things, truly art.
A bit off-topic I admit, but I never know what to make of Fram oil filters: I often hear that they're a no-go when choosing a filter brand, but then I see them on these high-value cars.
I think that is just old bad information that’s part of the automotive world, I’ve been an engine builder my whole 51 years in the business, we use Fram on these v12s exclusively. Never have had an issue , and at a cost of around 50 k per engine, you don’t take any chances on unproven parts.
I can possibly help answer you.I worked for a largeish motor factors and Fram spin on oil filters were our main stock.However we did have occasional issues that their threads didnt quite match the recieving thread on the engine and on one occasssion as a separate issue a filter " burst" at its base plate although Fram said it had been overtightened and /or the oil pressure relief valve on the car may have siezed shut.Overall however we had very few returns.
There is an evil showing its head like never before. If you do a little research into what’s going on on this planet, let’s just say you would want to stand up and fight for our right as human beings to thrive and survive on this planet.
I was out in my classic mini yesterday. I almost had my teeth rattled out on some sections of road never mind having to swerve massive potholes. Terrible state.
I've seen a lot of exotica roll by on this channel but this Daytona takes the cake for me. Even my boyhood hero the F40 can't hold a candle to it. What an absolutely beautiful beast of a machine. The lines are so clean. Just imagine being fortunate enough call this one yours.
The Daytona, that was one of my fantasy cars in it’s day! Always a toss-up between the 250GTO and the 365GTB/4! And Alain de Cadenet what a car mad gent he was. His car test film series, Victory by Design, which had him driving a procession of cars around the beautifully scenic Wooton Lodge, was always entertaining
Listening to it makes me smile. Makes me want watch the opening of The Gumball Rally movie with the 427 Cobra's and Daytona Spyder's exhaust sound echoing through the streets of Lower Manhattan. Not a great movie but it had it's moments.
I love these long-form vids with lots of details and the test drive. The 365 GTB is a magnificent machine; the shape of the body and the sound of the V12, simply amazing. I can only hope a 275 GTB/4 will one day grace this channel.
@@iain_tyrrell Ian, I consider you to be the Bible for classic cars. All the little details and nuances that you have gathered over your years of working on these cars are just fascinating to learn about. Thank you for sharing with all of us.
The pipes likely acted as somewhat crude Helmholtz resonators, working to cancel out a droning exhaust sound. By delaying the timing of pressure variations, you can selectively cancel certain frequencies based on the length and diameter of the pipe. I would very much like to see the inside of the silencer to determine how it recombines. It may also promote power at a certain RPM. Either to tune out a power dip, or give a boost at low or high revs to improve driveability. P.s. US auto regulations continue to be a thorn in the side of automotive beauty. Love the old plexi's. edit: For the inclined and the pedantic: Helmholtz resonators are typically closed. But the phenomenon remains regardless of terminology.
The Super-numery pipes are there to stop the pressurewave from reflecting back into the cylinder head- there is a degree of valve over lap that can allow reflected back-pressure to stall the aircharge coming past the intake valve and defeat the scavenging that is sought. It's all about helping charge the cylinder and improve volumetric effeciency. Always look to harmonics when you see things like that. I hope this explanation helps.
Fabulous. When I fell in love with Ferrari in the late 90's, I can still remember seeing the Daytona (correct me if I'm wrong) for under 100k USD. Back then we didn't have great RUclips channels like this so I had to enjoy the sights & sounds of the marque vicariously through VHS tapes : )
All I can add to all the positive comments is that Iain, you sure are one incredibly fortunate man to have the opportunity not just to work on such automotive art but better still get to enjoy them out on the road as they were intended to be enjoyed. Thankyou, we appreciate your clear enthusiasm for this. 😁👍
In the late 70's a family friend came up our drive in a JCB Daytona, he took me (then a car fascinated 12yr old) for a spin. It's a wonderful memory to this day. A beautiful car.
Such a joy to watch Iain, whose passion is so infectious. Love all the details about the Daytona's design, history and especially the road test -- his mile-wide smile says it all. Thanks, Iain!
I met Allan de Cadanet, only once, he parked outside a friends London home is his open topped 1950's Alpha, reversing the tail pipe into a pile of sand (builders next door) then we went to a steak restaurant and he paid the bill for all three of us. I found him to be very entertaining, great company, which he obviously was skilled at, with that public school boy confidence and aire that justifies the fees . He said he bought the Alpha, I think in the 60's, and if I recall for some incredible figure, I think he said £75 !!! He turned down £750,000 for it. Not a bad investment. A nice chap RIP.
The "nerdy" bits are precisely why I love these videos. Four degrees difference in the cam lobes front to back? I have an even greater appreciation for the engineers at Ferrari.
I understand this was true of the big 429 Ford cammer engine as well. 6ft. timing chain length must have caused some consternation for tuners.

Wonderful, wonderful , wonderful. Fantastic video Iain of a timeless classic.
When I had worked at a classic car shop, I had the privilege to drive a Daytona Spyder that wasnt in Concours condition, but it was a nice car. A driver's car.
We had just performed a tune-up, and when I went for a test drive. I instantly fell in love with the car. From how smooth changing gears was to the engine's responsiveness and sewing-machine-like smoothness. When you put your foot down, oh how she went and wanted to keep going too!
For this car, the steering did have a little bit of play in it, but nothing that was like driving a truck. I was quite surprised at how light the steering actually was. The previous car I worked on was a Testarossa, and the Daytona took much less effort to drive, including in the parking lot. The suspension was also just splended with how it absorbed the bumps and undulations in the road but you always felt secure, in control of the car.
Truly has become one of my most favorite cars. Whenever I do find myself with the money to purchase a Daytona, I will most certainly will without any hesitation
The last real Ferrari. And a milestone in Design.
So much history and lore in one video. From the car and the man. Excellent.
those door pulls are so neat and as you've shown when they work well they are very satisfying
The best door pulls ever are those on the original XJ6 - very classy and solid looking. They make the Ferrari ones look flimsy.
Is this the longest Tyrrell's video every? And about my favorite Ferrari. What a treat!
I remember this car fondly as a young buck. Whilst living in Germany, I had many Auto Quadrat? - Trumpf? Card games where the 365 GTB was the card to have. It and the Lamborghini Miura trumped all other cars/cards in the stack…. Cars of the late 60s and 70s was the era of classy/beautiful/sensual/elegant design! What a time it was! Thanks for the memories. Ferrari was the business!
And I commented that Tyrrell's video on the 250 GT Coupe was one of his best, but this is equal to that one.
Thanks indeed!
Was lucky to drive for the day an original Daytona convertable in the early 80s. An experience you never forget. We also had an AC Cobra 427 for a day now that was a dangerous thing to drive down Yorkshire narrow country roads. Terrifying but an experience never to forget.
Iain I have to agree, I was twenty something when this car came out with the correct lights. It is still a great car. The induction and exhaust noise is amazing. I remember reading somewhere way back that the additional exhaust pipes created a vacuum ahead of the exhaust gas leading front and acted as a secondary scavenger system.
Thank you very much once again Ian, for the high quality video you posted. Nothing to discard, only the sheer pleasure to share your knowledge and enjoy the beauty of the automotive world.
Thank you!
Lovely video. I’ve always been a massive fan of the Daytona or 365 GTB/4 to use its full name. Without a doubt my most favourite Ferrari. Such a stunning looking car even over half a century later. A masterpiece and so far ahead of it’s time. Full of state of the art design for the late 1960’s. Thank you Iain so much for great in depth video. What a beautiful Daytona.
This was my favourite Ferrari as a teenager. I love how the front is designed to look like the Rover SD1 😉
Erm….😂
Thank you for the close up look at the bottom of the beauty 😉
And thank you for taking us along for the ride. I realise it is tedious work freeing up a Daytona suspension. But hey, someone has to do it.
I like bottoms too.
As a young 17 year old I got the prelidge going to Chenitte’s in Greenwich CT to pick up a new exhaust system with a neighbor for his 330 GTC back in 1978. We got a walk around in the basement and saw a Daytona covered in dust with a customers repair invoice with probably almost more than the car was worth. Explains the dust. Stunning car thanks for the memories!
And those "hidden" windshield wipers, what a details on this beautiful car! I know that Iain doesn't like the word iconic, but maybe this is an iconic car......! Thank you for the video, I love it. Let's hope that the owner decides it to leave this Daytona as original as possible!
Iain that note on the paper on the dash read “ don’t forget your top gun sunglasses Iain”. The other surprise on this car is the driving position which looks spot on; no short legs and long arms. It would be good to show people how those wheels are removed- most wont believe it! Great film and full of little Daytona nuggets. Who knew linear power curve to 7700. Almost unheard of on other cars. Porsche didn’t go this route. Nor Jaguar. 5.6 seconds is another world in 1969!
Thanks so much for this Iain. This is my all time favourite car so beautiful and the sound is awesome. I didn't know Alain De Cadenet has passed away such a gentleman, great driver and car enthusiast I loved his Victory By Design series .
DON'T STOP,,, The DAYTONA is the GTO's brother in my view ... Excellent Iain once again,
Thanks!
Wonderful video Iain brings back memories when as a 16 year old schoolboy I was lucky enough to get a lift by my neighbour in his beautiful Daytona on his way to work. Just a glorious sound and the acceleration was amazing. Been my favourite Ferrari ever since. 😊
Thank you too!
The super numary exhaust pipe acts as a by pass for built up gasses that are produced by back pressure.
As the exhaust gasses leave the engine they are in free flow until they meet the baffles in the first silencer, these baffles create back pressure. A bit of back pressure is OK but not too much as gasses then can't exit the the cylinders freely. The extra pipes act as a method of releasing some of that unrequired back pressure by allowing some of the gasses to escape the main pipe and enter the silencer by a different route. It's all about control of back pressure.
Wow....i smiled the whole way through this video. As a child in the early 70s I played 'top trump cards' and this was my favourite from, one of the many car type card pack me and my brother played together. To see it so many years later in the flash..well its better then I imagined at the time. Wonderful to see. Thank you very much. Superb ....Cheers
That’s lovely- thank you. It’s comments like yours that make the effort of producing these videos worthwhile
Always loved the Daytona/ 365 GTB. Glorious sound when you open the taps. 1 would be added to a collection if funds allowed, its 1 of the few Classic cars that has never aged.
WOW!! My favourite road car of all time... Think I'll watch that all again! Thank you Iain.
stunning, absolutely stunnin...what a classic
The Daytona and the Testarossa are my favorite Ferraris. If I ever won the lottery, a big lottery, I would make sure to get these into my garage. Great to see them together. To dream.
Clay Regazzoni owned one and drove it daily
In Maranello people used to talk about his legendary commuting 'lap' times on the trips to and from the grand prix locations around Europe. Still to this day.
This brings me to think that this car was something else for its time.
Automotive royalty for sure. Well done Iain, keep channelling the sublime!
The design of the camshaft really impressed me, off setting the rear lobes to allow for the torsion or twisting of the shaft under load is just ridiculous attention to detail.
15:23 the difference in the timing of the camshaft has probably more to do with the lag of the carburetion rather than tensile factors
Interesting
...so good of you to mention Mr. de Cadenet...Great show.
I bought youtube premium just so they couldn't interrupt Ian on his discussion nerdy bits! Well worth it 🙂
I was told by the ansa rep, whose products I sold in the 1970s, that the super numery pipes are for harmonic tuning. As such I consider them a great success. One of the best sounding cars I have ever experienced.
My god what a glorious sound!!! Mister Tyrrell you are a engine magician👍
Superb thanks for sharing. You bring my old days of reading classic and sport car to life, including write-ups by Alain de Cadenet 👌
That Daytona looks mint. I bought such as Road&Track, read Brock Yates whilst in sixth form. The oil crisis came soon after when values crashed. Setright, also musician, wrote an article on the musical harmonics of the exhaust system.
I remember going to Italy to visit my family in 74 and there was a white Daytona in the building as an 11 year old i was drooling over it every day, beautiful car, you are absolutely tight about a compression leak test, i remember a mercedes 190 tha passed with flying colours a compression test and had a 60% compression leak at tdc.
Leak down much more revelatory
Who could forget the 1970’s movie Gumball Rally featuring a rare convertible Daytona…such a fun movie for all lovers of anything automotive…
Great video as usual, Iain. Nice to know that my humble 2.4 Fiat Dino coupe had the same valve timing as a Daytona. Redlined at 8000, although I only ever went up to 7500, the Dino engine always pulled very smoothly low down and gave a noticeable surge as it hit 4000. Great sound too, needless to say!
I'm half in this video, but I have to stop and comment this is one of your best/one of my favourites.
Thank you!
+1
what an absolute joy to see Iain's face light-up as he puts her through her paces.
The value differences of Daytona's today are significantly higher than the original cost differences between the E-Types, Ghibli's and especially the Rolls, so history has proven that the Daytona was worth the extra money.
The first video I ever watched on this channel was a preceding one of the 72 Daytona Spyder convertible. I was introduced to this car via Miami Vice (The authentic one)as I'm sure were many. I continue to like it more than the Testerossa. Over the years I've rarely caught glimpses of them in the media.
I know why now. They are scarce. Great to make your acquaintence Tyrell. What your doing is beautiful. I shall look forward to future and catch up on past content.
3 hours more of my favorite Sunday evening entertainment? I wouldn't move from my sofa if the house was on fire!
What a marvellous video, I will never be able to own a Ferrari but watching and hearing iains enthusiasm makes me feel like I do😊
Iain, I live my exotic car obsession vicariously through you and this channel. I love to see you bring to life and enjoy the classic exotics that you work on. I absolutely love the early Lamborghinis and Ferraris specifically… with the combination of rawness and elegance that they exhibit. I think the Italian styling of that era is beautiful…especially so when contrasted to today, in a world where all the supercars look basically the same (in my opinion). The individuality of the classics is wonderful to see. I personally think that the Lamborghini Miura is the most beautiful car ever built, and I always love when you do an episode on them. You bring them (the cars) to life in your workshop for the enjoyment and pleasure of all of us who likely will never get to personally experience them. Thank you!
Thank you too- great to hear!
What an astonishingly wonderful looking car - and the plexi-glass versions are certainly more appealing.
I remember Richard Hammond drove one in a tunnel in France! He said you are watching a man falling in love again!
I love the info on the valve timing on the V12 and V6 being similar giving the lovely linear power curve. I was given a spirited ride in a 246 Dino when I was 17 and have loved the V6 ever since.
What a wonderful mustache you got at 30.38 ))
Para mi el mejor ferrari de todos los tiempos y sin duda el mas bonito
Question, Sir Ian. What effect does the Xtra 4 degrees on the rear lobes of cam have on the engine/driveability at low rpm?
Seemingly none whatsoever. Interesting question
Another excellent review by Iain. He is always entertaining and educating. A great piece on the Daytona. I’ve got a 575M..like Iain said, nothing drives like a front engined V12 with rear gearbox.
Enjoy the 575!
Imagine not being excited enough about your brand-new V12 Ferrari to even be bothered picking it up and driving it home...
Really fantastic video, so many interesting details, does justice to the original design and intent of the engineers who created these beautiful things, truly art.
A bit off-topic I admit, but I never know what to make of Fram oil filters: I often hear that they're a no-go when choosing a filter brand, but then I see them on these high-value cars.
Farm were original equipment on Ferraris for decades
I think that is just old bad information that’s part of the automotive world, I’ve been an engine builder my whole 51 years in the business, we use Fram on these v12s exclusively. Never have had an issue , and at a cost of around 50 k per engine, you don’t take any chances on unproven parts.
I can possibly help answer you.I worked for a largeish motor factors and Fram spin on oil filters were our main stock.However we did have occasional issues that their threads didnt quite match the recieving thread on the engine and on one occasssion as a separate issue a filter " burst" at its base plate although Fram said it had been overtightened and /or the oil pressure relief valve on the car may have siezed shut.Overall however we had very few returns.
The smile on your face whilst on the test drive, is worth a thousand words!
The state of British roads is shameful. They're a bloody national disgrace.
I’ve hit a few recently. Think I need pot hole headlights
There is an evil showing its head like never before. If you do a little research into what’s going on on this planet, let’s just say you would want to stand up and fight for our right as human beings to thrive and survive on this planet.
Keep sending money to Ukraine..... road tax =just another legal govt.(terrorist) tax ....
Same in Australia. Seems to be an English thing.
I was out in my classic mini yesterday. I almost had my teeth rattled out on some sections of road never mind having to swerve massive potholes. Terrible state.
I've seen a lot of exotica roll by on this channel but this Daytona takes the cake for me. Even my boyhood hero the F40 can't hold a candle to it. What an absolutely beautiful beast of a machine. The lines are so clean. Just imagine being fortunate enough call this one yours.
Yes indeed-
Unpopular opinion. The Daytona was like a huge downgrade (designwise) coming from the 275 GTB/4.
Upgrade in my opinion 🤷♂️
100% agree
Subjective!
Do you have one? If it’s a downgrade I will take it off your hands for £100.
Tell that to the sellers. Maybe they will lower the asking price.
Such detail, makes the channel stand out from the rest 👍🏻
Thank you!
The Daytona, that was one of my fantasy cars in it’s day! Always a toss-up between the 250GTO and the 365GTB/4!
And Alain de Cadenet what a car mad gent he was. His car test film series, Victory by Design, which had him driving a procession of cars around the beautifully scenic Wooton Lodge, was always entertaining
Listening to it makes me smile. Makes me want watch the opening of The Gumball Rally movie with the 427 Cobra's and Daytona Spyder's exhaust sound echoing through the streets of Lower Manhattan. Not a great movie but it had it's moments.
I love the history, the technical description and stories of your experience with these cars. Fantastic. Thank you.
Glad you like the combination. Thank you too
I love these long-form vids with lots of details and the test drive. The 365 GTB is a magnificent machine; the shape of the body and the sound of the V12, simply amazing. I can only hope a 275 GTB/4 will one day grace this channel.
Let’s see next time a 275 comes in. Thanks
@@iain_tyrrell Ian, I consider you to be the Bible for classic cars. All the little details and nuances that you have gathered over your years of working on these cars are just fascinating to learn about. Thank you for sharing with all of us.
The pipes likely acted as somewhat crude Helmholtz resonators, working to cancel out a droning exhaust sound. By delaying the timing of pressure variations, you can selectively cancel certain frequencies based on the length and diameter of the pipe. I would very much like to see the inside of the silencer to determine how it recombines. It may also promote power at a certain RPM. Either to tune out a power dip, or give a boost at low or high revs to improve driveability.
P.s. US auto regulations continue to be a thorn in the side of automotive beauty. Love the old plexi's.
edit: For the inclined and the pedantic: Helmholtz resonators are typically closed. But the phenomenon remains regardless of terminology.
Best auto-vision channel on youtube or anywhere !
Thank you very much! Delighted to know you enjoy the videos.
The Super-numery pipes are there to stop the pressurewave from reflecting back into the cylinder head- there is a degree of valve over lap that can allow reflected back-pressure to stall the aircharge coming past the intake valve and defeat the scavenging that is sought.
It's all about helping charge the cylinder and improve volumetric effeciency. Always look to harmonics when you see things like that.
I hope this explanation helps.
Thank you. Very interesting
@@iain_tyrrell Thankyou for your program!
What a treasure, both your knowledge, the car, video editing... 😍😍😍👏👏👏
Thank you!
Man that gave me chills when Iain opened up that seemingly sleepy V12. Great video as always. Cheers from the US!
Wonderful. Iain never disappoints. Fabulous cars, great production, endless knowledge, and that V12 howl.
Fabulous. When I fell in love with Ferrari in the late 90's, I can still remember seeing the Daytona (correct me if I'm wrong) for under 100k USD. Back then we didn't have great RUclips channels like this so I had to enjoy the sights & sounds of the marque vicariously through VHS tapes : )
All I can add to all the positive comments is that Iain, you sure are one incredibly fortunate man to have the opportunity not just to work on such automotive art but better still get to enjoy them out on the road as they were intended to be enjoyed. Thankyou, we appreciate your clear enthusiasm for this. 😁👍
In the late 70's a family friend came up our drive in a JCB Daytona, he took me (then a car fascinated 12yr old) for a spin. It's a wonderful memory to this day. A beautiful car.
JCB?
The Daytona owner, Mr Bamford, of JCB company
Such a joy to watch Iain, whose passion is so infectious. Love all the details about the Daytona's design, history and especially the road test -- his mile-wide smile says it all. Thanks, Iain!
I met Allan de Cadanet, only once, he parked outside a friends London home is his open topped 1950's Alpha, reversing the tail pipe into a pile of sand (builders next door) then we went to a steak restaurant and he paid the bill for all three of us. I found him to be very entertaining, great company, which he obviously was skilled at, with that public school boy confidence and aire that justifies the fees . He said he bought the Alpha, I think in the 60's, and if I recall for some incredible figure, I think he said £75 !!! He turned down £750,000 for it. Not a bad investment. A nice chap RIP.
Thoroughly enjoyable run through of the Daytona ! The V12 creates a sound to behold - many thanks for sharing.😊
Such a delightful episode, Mr. Tyrrell. I love how the Daytona puts a huge smile on your face.
Thank you!
I find this channel by far my most favorite auto content on RUclips.. and I love the nerdy bits..
Unreal video. Love it. The noise and the grunt are beautiful. I envy your job. David
I've never really paid much attention to these before but it's absolutely stunning! Thanks for the education. Simply beautiful.
