It's certainly possible and could be done for racing purposes. As mentioned, would require larger SC, ported and polished everything, forged and shot peened everything, redesigned cams, 14 to 1 compression, massive engine and SC cooling, VP Purple, no cats, and twisting to 9000+ rpm. Zero drivability on the street. But why do that if there's a perfectly good V8 suited for the job putting out the same power with more torque without having to spend $50k+ on an engine build?

True. Never said I bought it. Just said it's possible. What would be the point? A lot cheaper to go out and buy an SVR and a VAP tune. (Sorry...having another logic attack).

Unhinged.... that is nonsense. The only accurate part is the supercharger swap (no porting needed) and no cats. The compression ratio doesn't need to be that high at all and you forgot that there is plenty to bore in the V6 (up to 3.7L without changing the crankshaft). And it's a bit less than $50K, more like $41K. The car remains very driveable too. The cams also can stay, head rework, deck honing etc. and of course water/meth injection. You also need to add, transmission upgrade pack to 900NM, Also, runs happily on 95 octane thanks to water/meth.
Anyway, yes, the V8 is so much better ;-) ;-)

Agreed, v8 wins EVERY TIME because in the real world you can also theoretically do all those same tuning things to a v8

Can you just provide links to what you’re referring to so that the rest of us can read/watch an F-Type with this setup?

No you CANNOT push the V8 to that level of boost (22psi+) safely
No you cannot bore a V8 further
Internal testing at JLR shows that the V8 is good to 750hp at best due to limitations such as crankshaft, block and heads design and thermal integrity.
No it's NOT a guestimate in price, when you see something as precise to the $1K perhaps there is a reason.
NDABunka, you are in the Official Jaguar F-Type owners Club North America on Facebook... Videos of that car are plentiful from ripping a Hellcat and for 190mph runs...Rumor has it that one V6 car in this forum is in the 500/530hp range from this forum too (Punisher). with a lot lower end mods. The last one I am not 100% sure but based on the mods done it's very possible.
Expecting that someone wants to be copied is pretty silly, maybe they should post the part numbers needed as well..
Tuners keep their secrets and maybe they share a dyno sheet to those that want to spend the money to do it. Other than that, those that do get to have a blast and the satisfaction to tear up the track. There is no glory in posting their work just to have a bunch of people throwing negativity their way.This thread is proof of that.
Besides, I know personally that Stuart at VAP has told someone that wanted such work done that they can handle it in collaboration with an engine building shop near them. Ultimately this person had the work done but did not use VAP just because of their time schedule and not for any other reason (nothing negative about VAP). I know what his engine bench dyno tests are like,so yes he can beat an SVR even one with tune and pulley.What I hope people get out of this thread is that if someone wants to spend enough money on their V6, they can get a lot out of it and it's not to be underestimated. It probably makes no financial sense to some but there are V6s in the 500 and 600hp range, some will even add NO2 (dry) for a 75hp cheating gain.
Now the negativity will continue...

Unless you are racing in a class that limits you to 6 cyl or a certain displacement, I'm not sure why you'd bother though as you can get any of the V8 F types to 605hp for $1k and about 20 minutes of your time.
We can all go back and forth with this but until we see a dyno chart it's all just wind.
2 cents,
Dave

You can tune any engine to be hugely power, I had a Golf R, I could tune that to 600HP and destroy any F-Type V6 or V8, but did I, no because guess what I don't want a 4 cylinder car, sounded rubbish even if it was silly fast.
I drove the V6S, V8S and SVR, once I'd driven a V8 I simply had to have a V8 and I wanted a car that sounded incredible and went bonkers fast out the box with a warranty.
If I went V6 I would had to tune it immediately to get any kind of satisfaction and then I'd be looking at making serious power not just the usual 450HP or so from bolt-ons and as such I'd end up spending a lot of money and doing something not many have done and in the long run, I'd still rather have the V8.
Both cars are great, but your either a V6 or V8 guy, I am a V8 guy and for me it has to be the V8, even if it was easy to make the V6 go quicker than a V8 and not a lot of money, I'd still buy the V8.
I'd also still buy the SVR, I wanted the halo model, the rare one, the one with the silly big wing and all the respect and sense of occasion that comes with own a super special and super rare car.

I think you are saying that the $41K figure does have foundation & knowing your background I fully believe you. What I am saying is that spending $41K or $50K (why not throw another $9K at it at that point) is pointless IMHO as it make no financial sense but perhaps a multi-millionaire wants a v6 so that they can track it in a restrictive class and therefore it would make sense... to them.

Yes and no... you can fit the upper pulley and the car will run fine, but it will only gain a little low end power.
On your SVR (and the 'R') the electronic bypass valve in the charger is set to bleed off boost at 13psi. So adding the upper pulley will make more power up until the point the boost hits 13psi and then it will bleed off any excess.
In point of fact, the car is mechanically capable of 15psi of boost, on the stock pulley just by shutting the bypass valve via ECU Tuning.
Adding the upper gets it to 16.5psi, the crank to 18.5psi.

Thank you, when I do this I shall literally just go with the lower pulley, uprated intercooler and your tune I think, based on that with 18.5psi what theoretical power am I looking at, 650HP?
Does the Project 8 600PS tune allow the full 15psi of boost then to hit the magic 600PS number or did they do it via fuelling and spark adjustments.
