800 H.p. On Stock Cyl Head ???

[TCluff]

Anyone Make 800 H. p. Without Cutting The Intake Manifold Off Of The Cyl Head And Going To A Fabbed Intake ??? With Or Without Nitrous

i do believe that Lmills just did 1125hp on a stock head! on spray, and 817hp on fuel alone. also i believe that Tim from TRE just did 875hp on fuel with a stock head.

W1cked did 1194 on nitrous and in the 800's on diesel only. . He runs a stock head, valves, springs, and cam. . Just good studs. .

I think w1cked has upgraded springs as he's turning close to 4000.

Nope. . Just stock springs. . I turned my stock CR to 3930 rpm on the dyno with stock springs as well. . I also run it at the track often. He used to run springs, valves, ported head, cam etc, but he said he had better luck with the stock parts. So that's what he has now. .

On your dyno run or any of your 1/4 mile runs at 3900-4000 rpm whats your boost at? Since your obviously not floating the valves at that rpm? I wonder at that rpm how much boost/backpressure it would take for the valves to float? Not that I feel its worth it but just curious since you have done it.

 

[JasonCzerak]

Yeah, that's what I was thinking, valve float. Don't the sled pullers have this problem with lots of boots and rpm?

 

[WUnderwood]

I did 909hp with the stock head, a little N2O
