I do not trust the numbers chassis dyno's report so to do a small compare here is Steve - C5 with heads, CAM, headers, larger injectors that was on the same dyno I was on with the Rebel.

Compare these closely and tell what you see

This is from start to end of 1 dyno pull for both C5s that both end of pull just over 130 MPH.

Graph is RPMs, MPH, elapsed distance and time






Here is a compare of MPH and the time it took Steve's C5 (S-MPH) and the Rebel
