Preliminary Warhawk ETP Canted Valve Results
Preliminary Warhawk ETP Canted Valve Results We made our first couple pulls last night on our Warhawk based development engine.
We warmed it up and broke it in last night. We had a chance to make a few sweeps, the highest being 7500 RPM. we still have 2000 rpm to go. It is a 4 inch stroke with a 4.180 bore. With a custom ETP manifold and 2 Fast throttle bodies on top. Timing was at 25 degrees and AF ratio was still on the rich side, about 12.3-12.5 We will continue to make more pulls after the PRI Show next week where we will have the engine on display. Fuel was C-14 VP.

How is that acheived?
What is the valvetrain and is the oiling system dry sump?
Is this just a regualr warhawk block with your heads on top?

Judging by the diminishing gains (if you plot those numbers on a curve) I don't think you will make power all the way to 9500rpm, even if you can spin it that high. You can always go prove me wrong though 
You're crazy enough to try it though

5000 rpm 530 lb ft
6000 rpm 612 lb ft
7500 rpm 602 lb ft
8500 rpm 540ish if the slope continues.
Motor could be peaked out but could be tunning etc. still one bad bitch at 860 hp.depend on how fast the TQ curve drops after 6000rpm could make alot more power. I don't think its finished yet however.
