I currently have a 2.8 kenne bell on my 2008 Gt500. I am looking at going to a 4.0 and wanted to see what some of you guys have used and how you like it. My car has a built motor. The engine has a ford gt block, Billit crank, H beam rods, Pistons, Head studs, Ported heads, cams, etc etc. I'm told that whipple is the way to go due to the Kenne Bell making alot of heat compared to the whipple. If anyone has used either, let me know what you think. Thanks!

I have a 4.0L Whipple - bugger hits hard!!
how much power are you looking to make?
This was at 24 psi on a "kill" tune
This is where I'm running it now at 20 psi

Thanks for the dyno sheet and video! Id like to see a 1,000hp all out pull. I still need a few other supporting mods. What did you do to keep the stock hood? Do you happen to know what your down stream air temps are?
Nice! What heat exchanger do you have and are you happy with it? Stock coolant pump?
we run the KB 4.2 and i make over 1200RWHP with a turbo 400. I run e85 and my temps at the end of the 1/4 mile are around 110. The liquid cooled 4.2 seems to run much cooler then expected.
whipple warranty/customer service suck .......
That's why I started this thread. I've heard alot of negative about both companies.
Some of it comes down to who you purchase it from and if they help/vouch for you when/if something may happen.
If Lethal, whipples largest distributor calls and says such and such happened, can you help them out, you really think they would say no?
Talk to these guys and become friends, not just customers and deal with them regularly and it can take you a long way, in my opinion of course.
I have a 3.4 and I am very pleased with it. If you are looking to go 1000+ I would say a 4.0 or liquid KB.

So you had an almost 200 rwhp differance with 4 psi?
Thanks guys... Its a tough decision. Kinda leaning toward the Whipple.
what kind of fuel are you running? i'd like to run a 4.0 at 20ish psi i was hoping to hit 900 rwhp.

Bruce, as you know i also have the whipple 4.0 , however i am running it on a stock motor with 18 PSI. The street manner are great and you cant feel the giant blower until you step on it. This blower is a monster, and it definitely needs a built motor to shine.
This blower is too much for me since i don't plan on building the block. I will be taking the blower off in the next couple of weeks and getting a smaller one. Since you are helping me out with the other parts , i wouldn't mind hooking you up with this blower if you decide to go the whipple route.
