dyno numbers for my build are in (cam + nitrous) - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I recently did
Comp cam (custom grind) 219 229 and .561 .572 113 lobe (small cam)
921 dual springs
hardened pushrods
kooks Long tubes (1-7/8")
GMPP offroad axle back exhaust (left stock mid pipes in)
New Era intake
ZEX nitrous kit with HSW 360 deg spray plate
Custom tune with 5 degrees retarded fot the nitrous

All dyno numbers are SAE correctred with no cools downs between tuning runs. We were in the 460's with engine only before timng was pulled for the final tune with the nitrous. If I could run two tunes that would be nice. The 5 degrees we removed made a big HP drop.

These are the nitrou pulls with a small shot and a medium shot. We just sized the jets as needed to get good AF numbers. With the 5 degree retard we seen no engine knock at all and kept AF down in the 12:1 range for the entire runs. This should mean real safe nitrous set up.

I though it was excellent that I was pulling in the 460 range with no timing removed and a cam this size. Escpecially with no dyno fan to help air flow out at all.
