This was the most dramatic race car I've ever seen. At the Silverstone Tourist Trophy in (I think) 1977 they were coming out of the Woodcote Chicane sideways and not fully straightening up until half way down the start/finish straight. They were unbelievably quick, having started from the front row and managing to lap backmarkers within three laps (on the full Grand Prix circuit). But the reliability - oh dear..............a year or so after this I went to work for Broadspeed and they were still bemoaning the "no dry sump" regulation. I was also told that they had signed a contract to develop the coupe and were somewhat shocked when that turned out to mean the XJC and not the XJS.
@@ppcmagazine Oh.... please do. They were really impressive. I was at the British GP in 1977 (£5 on the gate to get in - can you believe) and they demonstrated the XJC, possibly before it had raced. From where we were standing we could see its roof coming down the Hangar Straight like a streak of lightning.
@rogerking7258 You worked with some old school legends there then. Worked with a couple myself but obviously not @Broadspeed. I hear RBroad was a character to say the least.
I'ce just 1 word for the owner of this sublime car : a Huge BRAVO👏👏 !! The work that has been done here on this car is just sublime and apparently of great quality !! I'm a big fan of his Car ❤️🤍💙 (from 🇫🇷😉👍👌💪👋)
I wasn't aware of this project . I have 2 x 6L V12 engines and one 5.3 L in my shed . I had chose the V12 to develop as a 3/4 scale Merlin engine for a pop rivet kit P51 Mustang but the kit builder failed . I also designed a PSRU for the engine/ fuselage and later an aircraft kit but ran out of funds .The specs include overbore of liners to 7.0 L , fully polished and balanced crank / rods etc ., with an option of long main cap/block girdle/dry sump, flowed heads , reground cams to TWR WEC spec , full later Gore Tex gaskets , reprogrammeable engine management using 2 x Audi V6 (Denso) ignition , etc .The V12 had proven its reliability with TWR in the championship and was the perfect choice for the purpose as most of the kit builders , predominantly in the US were using the ubiquitous Chevy V8 . If you want an aircraft to look and sound like a P51 then it has to be a V12 .
The jag v12 by twr was by no reliable it was an horrific challenge just to keep it cool and it had about six different radiators. It also had a healthy appetite for oil.
I like this guy's attitude to the car, attention to detail without getting caught up in matching part number obsessiveness. For those that choose that way, I have nothing against, but it's deep pockets territory and like so many people I cannot afford that level of authenticity. A car like this is do-able for a greater number of people, and it still looks and sounds awesome.
Ooh now ya talking, definitely an old PPC mag cover car! What a beast. Having been enough of a masochist to have owned a Jag V12 I'd have chosen a LS as well. Keep up the great vids lads 🤘
The car is awesome! I own a JAG V8 supercharged and always loved the older XJ's especially John Steed's XJ Broadspeed in the Avengers. I saw one of the original Leyland race cars up at Gaydon Jaguar heritage last year, its just a busier which modern Jaguar could learn from. If I had the money? Robin has produced an awesome build despite no Jag engine 😉Great stuff!!!
Nice to hear and see it on the move on your YT channel, having read about it in the mag in the past. Sounds thunderous and has the looks to go with it.
That LS3 sounds so good. It's such a great option. Sounds better than the V12 and is super reliable. I mean, why wouldn't you. Just imagine how painful the V12 could be to try and keep going. It's a 🔟 From me.✅
Absolute beauty! I recently had an xjs pre he with a manual getrag in it and the diff from the manual 3.6 along with a few other upgrades that I did. I also had a spare pair of pre he heads that I had skimmed and polished but couldn’t find anyone to do the swap so unfortunately that was as far as I got. It was loud, brash and pretty quick for a heavy car. Would love that coupe though… 😊
Initially I gagged at the loss of the V12, but actually he's right, the costs are prohibative and at least it's a manual, making it quite the weapon! Also, it's his car, he can do what he wants with it and stuff the purists! :)
I was the same. But to gain 480bhp from the V12 it would need to be enlarged to 7ltr and literally all the internals changed with forged items. I know Harry Metcalfe spent a Small fortune to get to 350bhp! To keep it in brand, I may have chosen the Jag V8 supercharged😊
@@markwalton8644 The Jag V12 was originally designed as a race engine in the early 60s and was close to 500hp, but the road engine has obviously been simplified and downtuned.
I could imagine thar car painted a deep black. It would look so mean and nasty. Scare people when you went past them. But I liked it and a good honest build. Sounds fantastic and looks great. Nice Work Robin, be proud of what you have achieved.
Just imagine... this Jag powered by a 512ci or 8.2 liters Cadillac v8. A big block lump with all the torque and really no need to rev it like the LS. I would love such a thing.
@vincentdevri The trouble with a Cadillac 8.2L V8 is that it’s a big block engine(a really really big block) weighing about twice as much as an LS as fitted to this car! Nose heavy a lot! Handling not very nice!
@@ivatt442 I know it weighs a lot. The handling is going to poor anyways because of the long wheelbase. I'd rather have the low down grunt of the Caddy. Fits the car more I think
Pssh, sandals are the sign of true dominance. Many people claim not to give two hoots about what others think, but only a select few have the grit to follow through. Sandals = peak independence
A friend of my brother races a V12 (XJS) the engine has been reliable and long lived but he is conscientious with rebuilding it frequently. The LS is a very attractive solution, light and very well supported. Sadly if I was less lazy and better funded I would LS swap a Volvo 245, but we are all different.
Very wise, smart & practical decision to go with the LS. Though, I personally would’ve gone with the Jag 4.2 straight 6 with ITB’s, street spec mod with higher compression pistons, very mild cam as to not destroy drive ability with matching headers & exhaust. Focused on balance & lightness more than outright brute power, especially given that it wasn’t intended to be a race car. You don’t need 500bhp to have fun & the Jag 4.2 straight with ITB would sound so much better & be more fun on the track!
@@kasperkjrsgaard1447 Agree & would’ve been my 2nd choice. Though on a cost effective practically of the Jag straight six would’ve slotted straight in making it a much easier & less costly project. In addition, you don’t have to spend $60K on a full race spec V12 engine, especially when it is not used on the track as a serious race car competing in a series. You would not be able to drive the car on public roads with a full race spec engine as it would have no drive ability below 4000 rpm. Given that the car is just a show pony for Sunday drives at the local cars & coffee meet with the odd track day, why would anyone want or need to spend $60K on a full race spec engine?! Surely sourcing a used V12 engine & having it rebuilt properly to a street modified level engine would’ve been much easier & more cost effective compared to all the dramas associated with fitting an LS engine. The golden rule is always KISS: Keeping It simple stupid!
I guess it all comes down to individual taste. As a previous XJ12 owner, definitely not for me, it's like putting ketchup on caviar. Looks well put together though.👍
A very nice motorcar and I'm still coming to terms with the LS into a Jag C body, which although it is logical, it grates. One point on etiquette is that race numbers should never be used on the road, its bad PR for genuine motorsports competitors indeed, Motorsports UK frown on the practice. For more kudos a black line through the number might be more appropriate.
Big shame about the v12 was nobody made 4 valve per cylinder heads c n c aluminium would have made it a lamborghini killer. The engineers must of known this because it had a 12 /1 compression ratio and didn't really produce that much power. A big v8 engine and a live axle would never break but ho hum ..looks and sounds fantastic one of the best car sounds I've ever heard V8 RULES
Amazing car, probably better with the V8,in my opinion the six pot XK engine was better than the V12, I've had both and prefer the old six, I've got one in a mk1 Capri that I built in the 80s, just restoring it at the moment, can't wait to drive it again after it being laid up for 30 years😊
Another LS engine, again, vomits at a personal pet peeve.... having seen them proliferate during the last decade across most viewing shows/channel as a ubiquitously American sponsored/enforced engine swap. But at least the rest of it is good, even if it is definitely all unique towards the owners own choices and situation.
Sacrilegious, put a galon of petrol and a match to it. Its disgusting. I mean a Jag V12 from an XJS is about a grand then upgrade it you can get over 500 bhp esily. Worse thing is you used the worse ever shit engine in tje world. The sound is shot too TERRIBLE

The Jaguar V12 IS a very, VERY cool engine. But.......the standard engine which only puts out a maximum of 300bhp only gets SINGLE FIGURE MPG! Just imagine how much worse that would get with the engine taken out to 7.0ltr, hot cams, headwork, forged pistons etc. Standard they are supposed to be 8mpg (the later HE actually hit double figures....occasionally like maybe 10 mpg if you were very lucky) Plus as stated these are crazy money to tune, even just needing 12 spark plugs, leads, ITBs etc makes everything more expensive compared to a V8. These Yank V8s also have a colossal amount of decently priced tuner parts making the sky the limit power wise and WAY cheaper than any other naturally aspirated engine.
Luckily the mpg is totally irrelevant. Most big engined race cars only do 8mpg. (If you want to get across Europe fast and economically) then it’s A Beemer 530 diesel all the way! 👍😁👌

The later Jag 5.0ltr supercharged V8 with 500+bhp (depending on version) standard or well over 600bhp with a little tune. That Jag V12 doesn't do anything right (maybe smoothness?)
What a genuinely honest man creating a lovely car on a limited budget. Nice result. 👍

A beautifal Jag with a very pleasing soundtrack, awesome video guys.
Very lovely. Ralph Broad produced some wonderful race cars in my day.
Certainly did!
LS3 is such a good economic choice for an engine for this beast 😍😍🇦🇺
I'm drooling wow absolutely sublime
What a cracking car.
Sounds great
Series 2. I adore these jags. It's quite the special, I'd be happy with a Coupe in the six.
Sweet.... always loved the old Jag XJ coupe. And that sound with the V8... stunning. Keep up the great work!
What a car, what a sound.
Thats an AWESOME XJC....very well done
Props to Robin for making it happen 👍
Thanks guys, a great piece. Love the sound of that LS 😁

Yes I saw it too. I hope it happens!🙏
A chap very much down to earth with his car. I wish my mates that ask for a b road ride understood how much a new clutch is!
Awsome motor, congrats , , , had quite a few V12 jags, inc a manual 4 speed. Its the only car i regret selling! DOH!
Grace, Space & Paaaaaaaaccccee!!!
Back in the 80s, there were several Chev converted Jags here in Australia due to the cost of fixing the original engines.
Amazing!!
