I had a powerdyne kit on a 94Z228 with every bolt on and ran 12.72@110. I also put an 8# pulley on with a boost retard.I'm guessing with a stock Z28 and a 6# kit, about 330-340 at the wheels. I've seen alot of these powerdyne kits dyno very close to that.

I have a question. If i made a disapointing 315 rwhp with just a 4.5 psi kit on a 97 TA stock manifolds,just whats in my sig.And i also had 9 degrees falseknock and weak valve spring's and that hp was at only 5000 rpm then should i make close to 400 rwhp with a 6.5 psi upgrade,solid intake tube,larger air filter,Mac headers,off road pipe,cutout,larger injectors,aux fuel pump and dyno tunning... Am in in the ball park will my guess yes or no...
