Nice, good to know the tune works besides what the "butt dyno" tells us.

 

 

No, he has a R that he put the SVR bodywork on so his is a v8 with a tune that can bump HP from the 550 HP stock to as much as 650 HP. I don't know if he has that particular build but if anyone would, it would be him so not surprising with 75 HP more than a staock SVR that he was able to outrun it but it is good testimony for the tune

 

 

The title was a bit mis-leading to me. I was expecting to open this up to see the misery of a wrecked SVR that was perhaps actually... destroyed. In a way, it was a relief.

 

My bad?! The title is kinda misleading, I didn't consider the other meaning when I created the thread, I wasn't trying to click-bait anyone. It was just nice seeing the R pull on the SVR. Yes I am running around 650hp, and lesser weight bits here and there.

 

As destroyed is a bit far fetched.

Assuming you were both pedal to metal can you tell me how quickly you pulled away or how many lengths, what kind of pull was it 50-100mph?

I am sure you beat him, reason I am asking is because at some point in the future I do plan on doing the lower pulley, velocity map and an upgraded charge cooler or independent cooling setup for the SC with its own reservoir. So am just interested on how much of a difference there is as assuming you have around 80-100HP more than a stock SVR?

 

it was a 50-125mph pull. His front of the car was approximately 4 feet behind my cars rear at the end. Around 115mph my car gets a 2nd wind and power kicks in to push me ahead. Before 100mph, I was about a 65% car length ahead.

 

OK that is good to know.

I raced my buddies Mustang, its got a Whipple charger with around 800HP flywheels and it was also around a 50-120 pull, 50-90 we stayed quite level but beyond 90 he was pulling and by 120 is he was 2-3 car lengths ahead.

So sounds if I did these mods I could keep him within 2 car lengths but of course not a huge amount you can do about a car with 800 horses going to only the rear wheels. Of course from a standstill I destroy him and if its wet he has no hope.

Have you done both pullies?

Any cooling upgrades or still stock on the cooling side?

 

don't hold your breath for that one! ;-)

I hope there is video of this....

 

There are V6 that can do it and with nearly 180lbs in weight savings to help....

 

Not trying to pee in anyone's cornflakes and I like the V6 cars too.....but I've never seen or heard of a V6 that has been modded to make anywhere near SVR power.....in fact, I've never heard of one moddified to V8S power levels. ....and 180 lbs is insignificant when you're down 100+ hp. 180 lbs equates to about 20 - 30hp

There is a 195 hp difference between a V6S and an SVR.....and a tune gets you 36 hp.... both pulleys, exhaust mods, etc may get you another 20?

It's all about hp/weight so if you have a 575hp SVR at 3800 lbs you have 6.61 lbs/hp. a stock V6S with 380hp and weighing 3600 lbs would be 9.48lbs per hp and a modded. 450hp V6S at 3600 lbs would be 8lbs/hp.

To get to the same straight line performance as an SVR, your V6S weighing 180 lbs less would need to have 548 hp.

....so lets see pics of this 500+hp V6 F type. you could get there with nitrous but I've not seen one.

I know of now two V6S with more WHP than an SVR. No, it's not bolt-ons, those are not "tunng jobs", they are simply bolt-ons. What I am talking about is engine out tuning,machining, SC swaps etc.

 

Seriously? Please give more details, send links, etc! Would love to see these builds.

 

Ditto; I've never heard or seen a V6 Jag with 575+ HP; details please. :-)

I can personally attest to the VAP tune and crank pulley combo being more than just a “butt dyno.” I’ve done pulls on both a DynoDynamics AND DynaPack dyno. Got around 460whp on the “heartbreaker” and 523whp on the DynaPack. I also have the 200-cell cats and Eventuri Intake. I’ve edged out 2 hellcats, one from a dig and 1 on the freeway till about 130 and then we both had to let off the throttle. Also, I ran dead even with 2 Hurracans simultaneously (both my friends) from 50-120 mph before again, had to let off the gas. So yeah, I’d say the tune and pulley is definitely worth it. But be sure it’s the crank pulley. The supercharger pulley is way more work to install and the gains are fairly minimal. My 2 cents.

 

Yeah I'd do crank pulley anyway simply for ease of install.

The only advantages of upper pulley is price and the fact you don't need to tune for it.

Thanks for your feedback on VAP tune.

I think when I go ahead and do this I shall probably go VAP crank pulley and tune, uprated intercooler and continue to investigate running the SC on its own cooling circuit.

 

I suggest you take a look around in the F-Type Facebook groups... There are also videos of 60-120mph against a hellcat and the V6S wins several times.
