Specs: RSI 2.5L bottom end, Pacman/Erland cox 8V head, C2 camshaft with custom lobe centers
405 Whp at 16psi
448 whp at 18 psi
475 whp at 22 psi
I stopped right there, but we could have done well over 500whp and run up to 30 psi if desired. Dyno plots to come.
Bottom line, big HP pulling past 7k and and the flattest torque curve you have ever seen from 4k-7k.
8V ftmfw
OK, here are the scans.
Two things to note: 1) the motor was still making power at 7k where I chose to set the rpm limit. 2) there is a rich dip between 4500 and 5000 that would not tune out. We think there is some sort of resonance in the intake manifold at that point. I wonder what a custom intake will do?
