I agree with Quadcammer again... 12# he should be around 500 +/-.. Even with race gas 30-40 more...
His graph would read about 510 rwhp SAE... An aftercooler I believe drops psi by about 1-2psi but its a colder air.. so that might gain him a few. Lets say he see's 11psi... at 20rwhp per #... thats like 500 at the wheel... 30 more for race gas.... I wanna see a graph.. 612 I dont believe it...
