I'm running an original S-Trim although I may get it upgraded once we get everything worked out. My car hit 643rwhp before running out of fuel (too small a pump) but there was still 1000 rpm's left.
My SIG has all the mods although we have now added a return system, dual pumps, and an 8-rib system. I think we hit that with about 16lbs but it might have been slightly higher. My guess is that this combo will hit 700rwhp with 100+ octane and at least 600rwhp with 93 octane. I think the key was the Livernois heads and cam to take it from 400hp to where it is.
