Assuming a 15% Drivetrain Loss. What Internal/external Modifications need to be made to a 2015 Jaguar F Type R. To reach 915HP Crank.

 

Call and talk to: Hennessey Performance | Making Fast Cars Faster Since 1991

 

Hennessy doesn’t work on 2015 models.

 

In short....A LOT. Fuel delivery would need to be increased as well as boost. A custom tune on a Dyno would be needed, as well as replacing the connecting rods, head bolts (and maybe heads). May also need new pistons.

The issue then, is once you get to 915 BHP, it is doubtful the rest of the driveline would hold up. Rear Differential (since you are not AWD), axles, driveshaft, and the Tranny. While ZF8HP's are used in Demons and Hellcats, it is a different model with much higher torque rating. We have 8HP 70 HIS, and would likely need the HP 90 or 95.

Nothing enough money can't solve

yes. I agree. So to sum it up.

new rear diff axles driveshaft pistons connecting rods heads ,head bolts. I’ve already tuned the car. New spark plugs engine mounts. Working on getting the upper and lower belt pulleys.

thoughts on bigger intercooler? Different fuel Injectors?

 

It will need to be re-tuned/custom tuned after the fueling etc. are improved. I am not sure who/if anyone makes larger injectors for this platform? May end up needing to run E85 also to get that HP. And yes, cooling may be an issue. Bigger intercooler, and/or Methanol/water like I have would help.

No offense to Therock88, but talk to Hennessy Performance. That's what they do which is to turn cars into 1000+HP monsters... And they have been doing it for a long, long time.

 

i would like to do both. Yes ofcourse the car will be re tuned once new parts are added. Which water/meth kit are you running? Which Intercooler would be the best?

 

I'm just wondering if you are wasting our time or actually motivated (financially) to get your F-Type to this magical 900 hp figure? Have you found a qualified shop that is willing to make custom intercoolers, brackets other parts for this larger supercharger? This is a fully forged motor build with a 2.65 Litre roots supercharger that HAS NEVER BEEN DONE! You'll also need to run a new fueling system for E85. Is it possible... ofcourse. Do you have $60 000 for this build?

 

None taken. And would agree these guys build some machines. I was simply suggesting WHAT will likely be needed to accomplish it. I also think it will be very expensive to do. Interestingly Hennessy already has their F-Type build, but nowhere near that HP. Perhaps they know something we do not? They only got it to 623 HP at the low/low price of $10,000 ...haha


There is an aftermarket intercooler you can view at Paramount performance. It is made by another company (cannot recall who), but you can see it at the Paramount site. I designed my methanol kit and integrated it into the existing WS washer system. A link to my DIY thread below.

I used mostly AEM and Devil'sOwn products, but any combo can work.

F-Type Meth/H2O DIY

The original owner used to be on the forum. He sold it not long after the work was done. I'll see if I can dig up the thread but I'm fairly certain he wasn't attempting some monster build at the time. But I agree with you, a build like the OP is thinking about is going to cost a mint.

 

Yes. The car is tuned for a blended E85 without needing to replace the fueling system. So to reach those figures Full E85 is needed? And since we’re at that price point Should I Replace the Supercharger for a Screw?

 

Just a note...E85 typically needs about 1/3 more fuel as gasoline....So typically need larger injectors to get real benefit. Most of my experience here is on the Porsche 911 Turbo platform...But similar concept will apply to these or any car.

im quite fine Not running full E85.

truly the 777 is just a figure. If I can get 700 to the wheels I’ll be fine.

im very motivated as it has “NEVER BEEN DONE”.

 

What are you at now?
Any dyno runs of your car?
.

none yet. Tuner said 600. But I haven’t been on a dyno.

 

Not a hope in hell with our platform, different/bigger charger will be needed so new intake will need to be manufactured.
Everything i would imagine would need to be upgraded so doubt it will be off the shelf stuff.
Good luck because you'll need it

 

Anything is possible with enough money, but much less expensive to buy a car designed from the ground up for that purpose, even if it's a one-off custom.

 

Please post back any dyno numbers you make.
We are all very interested in how this turns out.

but I LOVE the Ftype R.

why is it so difficult to add 300 Hp?

it seems due to cost and lack of “**** it” money. This will take some time.

but I’m doing it.
