My Dyno Video : 3.4L Whipple Cobra Just posting this to show what I made. I am NOT trying to start a war, lol...
Car made 785/711 on 23 lbs.... Going to go with the Crusher system and 26 psi, and try for 850rwhp before having to do major fuel system upgrades... E85 Tuned by Performance Solutions.

That table top torque is very impressive. Great power.

what do you consider major fuel systems upgrades? My buddy was making less power than you with the smaller whipple and HPP said he was maxing his setup with dual pumps,60lb injectors.

I got a complete return style fuel system with 95lb/hr injectors and Dual 255's with a Boost A Pump. The system is set up for EASILY 1000+rwhp BUT with E85, you got to run 30% more fuel, so it limits it. Right now, we mathematically computed that I am limited to about 850 rwhp on my current set up. After that, I will go with a triple pump hat, along with the Boost a pump and at least 120 lb/hr injectors...

Well it's a VIS Carbon Fiber 03/04 Cobra Hood, and I did have to cut part of the fiberglass skelelton, otherwise it wouldn't close on the Whipple. Also, I have solid mounts, which lowers the engine maybe half an inch, lol...

I beleive that the pistons and rings are the weak link in the termi engine. Do you have a solid rear or are you still rollin on irs?? (my buddy got a 04 last summer, already had the solid rear, k-member ect.. had the stock eaton ported did some fuel system work, pullied and he made 540 on a aggressive tune without icing.)

My buddy has the 3.4 On his cobra he went with the automatic and trans brake runs in the high 9s I don't know what lb of boost he's on but he doesn have twin 420lph bosch pumps out back. What does your cobraq have for ignition on it I think he tried to run more boost but it was blowing out the spark I think.
