That sound is biblical. Always loved the XJC V12. This has only confirmed my view. This proves that tasteful and restomod can exist in the same sentence. Amazing car.
The sound from the rear of the car is genuinely astonishing. It has a near Ferrari-esque howl. A very well executed project. That 5.3 strikes me as an engine with an excellent basic design that was never fully brought to its best by Jaguar. Great work by the tuners here.
This could be peak Harry’s Garage, the length of time this has taken to get sorted, the journey, the amazing sound and Harry’s love, passion and enthusiasm is fantastic to see. What a finish! 🎉
Those pull-away clips are some of the most exquisite car content I've seen in a while. Simply perfect, and knowing the amount of effort and passion that went into this car makes it that much more special.
Out of all of the wonderful cars in your garage, Harry, this one is for me. And the noise, sublime with a bass undertone, so melodic! Well done to all who have created this masterpiece and to you, Harry, for taking us along. Thank you.
It’s easy to flinch when you think of the expense to get there, but this compared to the modern cars you review is just so cool, visceral and characterful - while the sound is just heavenly to any petrol head. Worth every single penny to own something so fantastic. I agree with others, by far the best car in the entire collection and one I’d love to own. A painful journey, but so worth it in the end.
I think this will be number one on the family garage heirloom list! What a Labour of love and only achieved because of passion, knowledge and that other old chestnut......money. This was the Jaguar Coupe V12 that got saved and Godspeed to Harry for that ability to be able to share this dream with all of us born in 1962! Cheers.
The colour looks stunning in the sunlight, the lines, the haunches, the curves, all scream scolded feline! What beauty and now with the blistering speed and sophistication that was Harry's vision. Top marks to the cameraman for the videography and editing, really managed to show off the Jaguar in all its magnificent splendor.
Fantastic sound! Point not mentioned was that the original injection and ecu was designed for very different petrol to what we have now. No wonder great results can be achieved with the correct modern upgrades and the right skills to set them up correctly.
Genuinely this has got to me my most favourite car in your collection. It's transformation from a pretty scabby car that existed 'because why not' to this absolutely beautiful and tastefully exquisite machine is amazing. The choice of colour is so amazing. A real perfect example of a colour that most would shy away from, but seeing it on the car its perfect. You chose the team of people so brilliantly to restore this car to better than it left the factory. All so incredibly knowledgeable and enthusiastic towards your specific niche. And it shows. It cost far more than the car is worth. But was it worth it? Certainly. Fantastic to see running and enjoyed.
This video was an absolute joy to watch, the culmination of all that hard work…and wow! What a beast that car is! The noise is incredible but still sophisticated, it looks so stealthy and classy, but it goes like a scalded cat. You look like a posh bank robber Harry! Thanks for sharing this journey with us all😊👊
That is a proper Jag. You built the kind of Jag that I would. Can’t find anything to say “I’d do this instead of that.” Having owned and built fast cars that are street driven… the Horsepower and Torque levels are in that sweet spot. Anymore, it becomes a liability and things wear out and break that much faster. Superb choices and excellent execution. Well done Harry and everyone involved!!
Harry you never fail to entertain with your content enthusiasm and passion. The sound of the V12 is infectious and I’m looking forward to seeing it in the future.
I kind of agree but coil technology in itself was very as it was.Coil packs were yet to happen.If you look now at how much HT can be achieved by modern stick coils per cylinder.The old V12 had one coil to somehow energise 12 plugs every revolution of the crank using one dizzy and one condenser.(actually every two revolutions?)You goto 4000 rpm thats alot to expect.Those old cylinder oil filled coils got very hot under high load and hated the damp aswell.As for fuel injection Triumphs system on their 2000 engines were an electrical nightmare as were the injectors that just stuck at will.
Harry, it’s been well worth the heartache to listen to the V12 singing through the exhaust. Very happy you saved the vehicle and look forward to a few south of France tours as it has plenty of extra luggage space.
Tom just blamed his inability to get the original system sorted on the system rather than himself. Of course this video is going to be nothing but singing the praises of the new system - it's all he was able to do. But funny how some mechanics manage to sort out the old system and make is reliable. I understand that Harry has his happy ending - and that's nice. But this conversion and video series has promoted a myth that the original system cannot function reliably. I've met mechanics who are experts in the original system and they know what to do with it. So, sorry, I can't get excited about old Tommy-boy. He's basically throwing together kit-injection that mostly sorts itself out. There are a million mechanics at his level.
@@andoletube Yeah I thought that too, but I have no experience with the ownership of the older systems. The conversation did touch a little on the immaturity of those early injections systems, I can only imagine the frustration that would cause on such a vehicle. Have you seen any good evidence that it can be reliably run for the extended periods one might expect? Cheers.
Love it - the sound of a proper engine in a real British gem. Good on you for restoring this beauty as it deserved. We miss this from British manufacturers today.
Oh Harry, this car restoration has been epic. What you and the team have done for this 'Gentleman's Express' is outstanding. Such a usable classic, looks and sounds amazing, it must be an intense pleasure to drive. As I have said before, this journey has been the most awesome of your entire collection. I salute you sir!
Those gains on normally aspirated with stock internals are really impressive. I always felt that this engine was very conservatively set up from factory. It looks and sounds amazing and the spacing on the first three gears seems just about perfect for the engine. Beautiful and addictive 😀
Harry as someone who's watched the story of this car the whole way through I've got to say I can't be more thrilled for you. That car is a real treasure well done on seeing it through and getting it running at its best
A huge improvement in the aesthetics of the engine bay! The previous induction unit looked like a messy bowl of metal spaghetti, whereas this new system looks both period-correct and good enough to show off. Well done! Your XJC is a real gem and has improved in every way since you started this process. The color is both beautiful and speaks volumes for the heritage of the brand. It looks like a true British GT coupe, like a genuine Jag, from every angle... and now it has the performance to match the great design.
Fantastic episode! The sound of that V12 through my headphones was sensational! So happy for you Harry and truly one of your nicest cars in the garage!
Got to be my favourite Harry's Garage video yet! Love this sort of approach to classic cars keeping the looks of the original but inhanced with some tuning and modern technology just shows what can be done to an old engine design 😀 very impressive figures and all on 9.1 compression this is great!
Makes me wish a hadn’t sold my pre HE xjs last year. It had the getrag manual, 3:54 diff, custom exhaust that went under the cage and not through it so I could keep it at 2 3/4 inch all the way from the manifold, larger throttle bodies etc and being the pre HE I bought a spare pair of heads and had them ported, polished, new valves etc and that’s as far as I got. Unfortunately I didn’t have Harry’s money and couldn’t afford to pay the cost for having the heads fitted. I weep at the money I spent on it only for someone else to benefit fully 😢. Harry’s car is a true master piece though, it’s everything you could want when you’re a jaguar lover like me.
As a person of a certain age I remember John Steed driving a green XJC in the "Avengers" & instantly adoring the car. Hard to believe it had such poor performance figures in "standard form". This is a stunning car & fortunately Harry you have been able to to give it the attention & resources it deserves for future generations to admire as we go electric.
This has been my favorite car in Harry's garage since he first bought it, and it just could not have turned out any better than this. Spectacular. If Harry said to me, 'Look, you can have any car in here, just pick anything you like', I'd take this Jag.
As many others have said. Fabulous to watch the Jag's story and restoration. The engine sounds incredible and your passion for the car is infectious. Hope to see it at Goodwood inn the car park pehaps. Wonderful machine, beautiful colour. The craftmanship of the guys who fixed it, as with the Fulvia is brilliant and fascinating. Thanks.
You now have arguably one of the best sounding Jag V12's in your possession, the larger TB's, filters and exhaust have been transformative. Looking forward to seeing more of the XJC this year
I have loved the Jag build, a fascinating series - enthralling even - and the grin on Harrys face with the finished product tells the story. Sounds epic, looks like it drives even better. Awesome 👍
the exhaust note is perfect. this could be an only car for me here in georgia, no salt on the roads. comfortable, fast enough, sounds great, and looks awesome.
Great mod, best of both worlds - Pre HE V12 with 6.0 litre fuel injection system. The H.E. (High Efficiency) V12 that you mentioned relates to the development of the V12 with digital fuel injection and the May Cylinder heads. These had a swirl chamber at the exhaust valve with a channel around the intake valve. Fitted to XJ-S and XJ12 models from around 1981.
What an utterly fabulous project the XJC has been. I’m extremely envious. One thing I noticed were the ‘headrests’. Or should I correct myself and call them ‘shoulder blade rests’?! That is a machine full of character and quality. Good for you Harry.
Yes, I looked at those 'head' rests and wondered whether it was Sir William Lyons who decreed that they stay below the window line, as he did with earlier cars.
I saw you in Burnfoot, County Donegal today. You overtook me a little later on the Slab Road. I wasn't sure if it was you until i heard the sound of the engine. Congratulations on the restoration and may you get much enjoyment from her. Probably the best sounding car in anybody's garage.
At last Harry absolutely delighted for you with the way this has turned out fabulous and intricate work by Tom beautifully explained step by step , in my opinion it simply couldn’t look or sound better ! Let’s have a road trip or track day video soon PLEASE !
Mint. The honest joy on Harry's face when he dropped it into 2nd and screamed round that bend was reminicent of me at 17 in a mini clubman on lanes i know better than the back of my hand. Pure joy. What a motor. Love it!
Love it. The glorious V12 running all cylinders is such a delight. Coupled with Harry's child like enthusiasm for finally getting this thing right. Bravo
Nothing like a proper manual & trans set-up to enjoy such engines...an auto trans on this car would be a shame...I once drove the LS9 Corvette with both auto and then swapped to a 6 speed manual..and the car was completely transformed in term of driving pleasure & performance ,dropping a gear from 4th to third and flooring it....amazing..!!..this jaguar is born again with these transformations..and all this with the comfort of a British leather interior..also this dash is gorgeous..looking at today"s ridiculous 'ipads' glass cockpits..I wonder what modern cars will look like in 30 years from now with their bugged-out computers & obsolete dash-boards..!!
What an awesome sound! Love the ethos with this conversion, with just a modernised intake and fuel/ignition control you have to appreciate that result. Manual conversion seals the deal. Hoping to get a similar result with my 911's 3.0 fitted with a later models intake. Thanks for sharing.
This is one of automotive youtube’s finest cars. So great that a car like this has undergone this sort of restoration. The people who have worked on this car are modern artisans and Harry a worthy commissioner of their services.
What an absolutely stunning car. I must admit this is my favorite car of Harry's. Just so utterly stylish, and now it has the performance and sound to go with it. How good does it sound!?
Fantastic rebuild! My friends dad used to run these, Geoff Uren (!), and I believe raced a Leyland XJC at Le Mans this definately took me back. Thanks Harry's garage...
2:28, during my time with Jaguar in the 80s we did many fuel rail modifications on the V12s to reduce the fire risk (many used to come in after engine fires). They had a lot of hose clamps, one of the issues addressed with the fuel rail mod (as the rubber fuel hoses harden the hose clamps no longer clamp as tightly and they start leaking fuel, leading to a fire).
Now THAT is an XJC that sounds and drives the way I believe an XJC should do - and always should have. It's beautiful to behold, beautiful to listen to and wonderful to watch / ride along in - even if only vicariously. Sure, the changes sound like they were massive, but they actually weren't and were only along the lines of allowing that 5.3 litre to breathe properly and more efficiently. No silicon chip to modify to get extra horses, no huge valves, no skimmed heads, no wild camshaft or non-standard pistons to increase compression - just the pure unadulterated essence and potential of the Jaguar V12......and I love it. Harry, mate, you have the best of both worlds in that car. She can be driven spiritedly and give you that gorgeous exhaust note to coax you into breaking the speed limit with effortless ease or she can be a laid back and wafty cruiser that just quietly eats up the miles in comfort as only a Jaguar can. Man, do I envy you....but in saying that, I couldn't be happier that she's exactly what the doctor ordered. I look forward to seeing you out and about in it as often as possible!
Harry, just hearing that V12 sing through my speakers put a smile on my face. I cannot imagine what it must be like in person. You have tastefully modified this example, and I cannot commend your efforts highly enough. To say that I am envious is a gross understatement. I hope you have many years of enjoyment and memories with this piece of art.
Music to my ears Harry!!! Thank you so much for this update. I am working on my XJ12's engine and following mostly the same path. I will be going with the Mobeck fuel injection/ECU with distributor delete but otherwise the same path with better exhaust and larger throttle bodies and suspension upgrade. Absolutely love the sound of the car! A manual tranny will be going into mine as well. Thanks again for this series...stunning cars these Jags.
I recently watched a vid where a gentleman was majorly modifying Ferrari Enzos to make them more drivable and faster on track. Completely tearing apart the drivetrain, stroking the engine, redesigning the front end for better downforce, revamping the suspension...the whole works. So your engine mods to this lovely Jaguar to make it more drivable is in the Big Scheme of Things, quite appropriate. BTW, I thought the revamped Enzo was actually better looking than factory, but then that design was always rather awkward-looking to begin with. No such aesthetic problem with your Jag, however. Big thumbs up!
Are the gains not actually more than mentioned Harry? Original power figures will be at the crank, not at the wheels like your dyno runs were. Add X% for drivetrain loss and I think you’ve actually done even better than realised. Great result regardless, it’s now got the engine to match the looks and handling. Terrific stuff
wow i can't believe. I have seen so many Jag videos and always thought ahh you could that or that, but with this one. It is just marvelous. Absolute dream car, the way it sounds, drives, looks. Such a masterpiece. This is how the Jaguar should behave. Well done!
I'd love to see similar treatment to an XJS with a V12 engine, with the interior being restored to a high standard. The XJS was advanced for it's time, is a lovely car, and it would be great to see one restored with this engine. Another project for you Harry please!
I'm kinda sad (in a selfish way) the journey has come to an end, because I loved every moment of this series. But what a car you've ended up with. And what a sound!
I know mpg really does not matter in the car like that, but from technology point of view it would be interesting to know how much it changed. And in what direction.
Oh dear me - the sound! That’s astonishing. Surely the cherry on the icing on the cake of a car both reborn and transformed. Congratulations Harry - you didn’t stop smiling throughout the entire video!
Possibly my favourite of all Mr M's cars.
Looks and sounds exquisite.
this or the Espada. Probably this one :)
It's not about you.
@@johnsmith1474 But, you’re coming on a thread to say this very thing, apparently everything is about you?
Was just about to say the same thing.
I would have invested in a hundred kilos of sound deadening ( equal to a passenger) to improve the internal sound , 71 dB is horrible.
That's a beautiful British car driven by a British gentleman in beautiful British countryside making a very melodious noise thanks Harry
That sound is biblical. Always loved the XJC V12. This has only confirmed my view. This proves that tasteful and restomod can exist in the same sentence. Amazing car.
toss up series 3 e
The sound from the rear of the car is genuinely astonishing. It has a near Ferrari-esque howl. A very well executed project. That 5.3 strikes me as an engine with an excellent basic design that was never fully brought to its best by Jaguar. Great work by the tuners here.
Sounding as good as it looks now.
Yes!! a simple phrase but so true in this case 👌
This could be peak Harry’s Garage, the length of time this has taken to get sorted, the journey, the amazing sound and Harry’s love, passion and enthusiasm is fantastic to see. What a finish! 🎉
All changed for me when he chose that paint with the Aston Martin guys.
@@muzman777 for good or bad?
Countach says keep holding my beer 😅
The sound is amazing and I’ve only heard 5 seconds of it
This is the sort of restomodding that works best, for me. Turning the car into what it should always have been. Marvellous.
Those pull-away clips are some of the most exquisite car content I've seen in a while. Simply perfect, and knowing the amount of effort and passion that went into this car makes it that much more special.
Out of all of the wonderful cars in your garage, Harry, this one is for me.
And the noise, sublime with a bass undertone, so melodic!
Well done to all who have created this masterpiece and to you, Harry, for taking us along. Thank you.
Me Too! I love it!
I couldn't agree more...
Maybe it's a car that more of us can relate to, a car we used to see about or lived close by.
It sounds so beautiful on that launch across the road, enjoy that lovely sound
I work for JLR Classic so get to see lots of really nice Jags, but I have to say this is a master piece!!
The smile on Harry’s face says it all. Who cares what anyone else thinks - the fact you love it (and that V12 noise) is all that matters!
It’s easy to flinch when you think of the expense to get there, but this compared to the modern cars you review is just so cool, visceral and characterful - while the sound is just heavenly to any petrol head. Worth every single penny to own something so fantastic. I agree with others, by far the best car in the entire collection and one I’d love to own. A painful journey, but so worth it in the end.
You only live once and you certainly can't take the money with you!
Can't BELIEVE "they" thought it'd be the best powerplant for the Scorpion tank!
Moneys a relative concept.
Of all of your cars Harry, this is far and away my favorite. Never let it go.
I think this will be number one on the family garage heirloom list! What a Labour of love and only achieved because of passion, knowledge and that other old chestnut......money. This was the Jaguar Coupe V12 that got saved and Godspeed to Harry for that ability to be able to share this dream with all of us born in 1962! Cheers.
I love the way that V12 sounds…deep chested, and yet with a buzzsaw edge. Wonderful.
The colour looks stunning in the sunlight, the lines, the haunches, the curves, all scream scolded feline! What beauty and now with the blistering speed and sophistication that was Harry's vision. Top marks to the cameraman for the videography and editing, really managed to show off the Jaguar in all its magnificent splendor.

Harry, you should seriously consider this XJC for next European road trip. Autobahns to alpine passes, the big cat would excel.
Amazed at how much money can be spent on a car trying to get it right that probably never left the factory right to begin with.

The coil from a Fiat 1000 does a great job as a replacement
Still isn't "right." It's a quirk-mobile for an elderly Englishman.
@@johnsmith1474 - why are you here watching then?
Just a beautiful sound with that magical delay for the gear change ….. just as it should be. Wonderful !!! Great work Harry.
You may never drive your Italian jobs again! The Jaguar is ACE.
Now that's how a video is done. Informative and fun, with a magnificent exhaust note!
Harry, it’s been well worth the heartache to listen to the V12 singing through the exhaust. Very happy you saved the vehicle and look forward to a few south of France tours as it has plenty of extra luggage space.

Nothing like a proper manual & trans set-up to enjoy such engines...an auto trans on this car would be a shame...I once drove the LS9 Corvette with both auto and then swapped to a 6 speed manual..and the car was completely transformed in term of driving pleasure & performance ,dropping a gear from 4th to third and flooring it....amazing..!!..this jaguar is born again with these transformations..and all this with the comfort of a British leather interior..also this dash is gorgeous..looking at today"s ridiculous 'ipads' glass cockpits..I wonder what modern cars will look like in 30 years from now with their bugged-out computers & obsolete dash-boards..!!
What an awesome sound! Love the ethos with this conversion, with just a modernised intake and fuel/ignition control you have to appreciate that result. Manual conversion seals the deal. Hoping to get a similar result with my 911's 3.0 fitted with a later models intake. Thanks for sharing.
This is one of automotive youtube’s finest cars. So great that a car like this has undergone this sort of restoration. The people who have worked on this car are modern artisans and Harry a worthy commissioner of their services.
Jeez Harry, those numbers are proper impressive for a 1977 car! 😳 And it's a stunning-looking motor. 😍 Love it! 👍🏻
The best blog I've watched on utube all week. So jealous it's not me behind the wheel with its 350 horses 😅
What an absolutely stunning car. I must admit this is my favorite car of Harry's. Just so utterly stylish, and now it has the performance and sound to go with it. How good does it sound!?
Fantastic rebuild! My friends dad used to run these, Geoff Uren (!), and I believe raced a Leyland XJC at Le Mans this definately took me back. Thanks Harry's garage...
Absolutely astonishing ! It sounds phenomenal Harry ….. well done
2:28, during my time with Jaguar in the 80s we did many fuel rail modifications on the V12s to reduce the fire risk (many used to come in after engine fires). They had a lot of hose clamps, one of the issues addressed with the fuel rail mod (as the rubber fuel hoses harden the hose clamps no longer clamp as tightly and they start leaking fuel, leading to a fire).
Harry, you and your team absolutely nailed this car. It looks and sounds beautiful. This is classic sports car sound done right.
Now THAT is an XJC that sounds and drives the way I believe an XJC should do - and always should have. It's beautiful to behold, beautiful to listen to and wonderful to watch / ride along in - even if only vicariously. Sure, the changes sound like they were massive, but they actually weren't and were only along the lines of allowing that 5.3 litre to breathe properly and more efficiently. No silicon chip to modify to get extra horses, no huge valves, no skimmed heads, no wild camshaft or non-standard pistons to increase compression - just the pure unadulterated essence and potential of the Jaguar V12......and I love it. Harry, mate, you have the best of both worlds in that car. She can be driven spiritedly and give you that gorgeous exhaust note to coax you into breaking the speed limit with effortless ease or she can be a laid back and wafty cruiser that just quietly eats up the miles in comfort as only a Jaguar can. Man, do I envy you....but in saying that, I couldn't be happier that she's exactly what the doctor ordered. I look forward to seeing you out and about in it as often as possible!
That is fantastic ! What an excellent result Harry and Tom
Harry, just hearing that V12 sing through my speakers put a smile on my face. I cannot imagine what it must be like in person. You have tastefully modified this example, and I cannot commend your efforts highly enough. To say that I am envious is a gross understatement. I hope you have many years of enjoyment and memories with this piece of art.
William Lyons will be smiling like a Cheshire cat.
Fabulous! A car that looks beautiful from any angle. Really nice photography on those Cotswold roads.
OMG the POWER INCREASE is MEGA
I’m not a classic car man at all. But this jag series has been one of my favourites- brilliant from start to finish. And wow what an end product 10/10
Music to my ears Harry!!! Thank you so much for this update. I am working on my XJ12's engine and following mostly the same path. I will be going with the Mobeck fuel injection/ECU with distributor delete but otherwise the same path with better exhaust and larger throttle bodies and suspension upgrade. Absolutely love the sound of the car! A manual tranny will be going into mine as well. Thanks again for this series...stunning cars these Jags.
I recently watched a vid where a gentleman was majorly modifying Ferrari Enzos to make them more drivable and faster on track. Completely tearing apart the drivetrain, stroking the engine, redesigning the front end for better downforce, revamping the suspension...the whole works. So your engine mods to this lovely Jaguar to make it more drivable is in the Big Scheme of Things, quite appropriate.
BTW, I thought the revamped Enzo was actually better looking than factory, but then that design was always rather awkward-looking to begin with. No such aesthetic problem with your Jag, however. Big thumbs up!
Are the gains not actually more than mentioned Harry? Original power figures will be at the crank, not at the wheels like your dyno runs were. Add X% for drivetrain loss and I think you’ve actually done even better than realised. Great result regardless, it’s now got the engine to match the looks and handling. Terrific stuff
That's what i was thinking, you loose somewhere between 15 to 20% drivetrain loss on the dyno.
Most dynos correct to flywheel power
wow i can't believe. I have seen so many Jag videos and always thought ahh you could that or that, but with this one. It is just marvelous. Absolute dream car, the way it sounds, drives, looks. Such a masterpiece. This is how the Jaguar should behave. Well done!
That’s the healthiest v12 jag of that era I have ever heard 🎉
Gladly its not a HE! The HE have cylinder heads from india and drop valve seats!
I'd love to see similar treatment to an XJS with a V12 engine, with the interior being restored to a high standard. The XJS was advanced for it's time, is a lovely car, and it would be great to see one restored with this engine. Another project for you Harry please!
I'm kinda sad (in a selfish way) the journey has come to an end, because I loved every moment of this series. But what a car you've ended up with. And what a sound!
What a glorious engine, worth the wait Harry - watched it twice now! Can't wait to see it in one of your legendary road trips 👍
I know mpg really does not matter in the car like that, but from technology point of view it would be interesting to know how much it changed. And in what direction.
What a beautiful car ,
How a car should look , bring them back , better than these plastic cars. Pleasure to appreciate and admire.
Thank you Harry
European road trip required Harry .
Oh dear me - the sound! That’s astonishing. Surely the cherry on the icing on the cake of a car both reborn and transformed. Congratulations Harry - you didn’t stop smiling throughout the entire video!
