how much horsepower

[99blueZ]

Hey guys - I'm gunna get my car dynoed to get the real #s but i was wondering how much power you think i have.

My car is a '99 Z28 6spd with 74k. It has FRA, K&N, SLP lid, SLP 85mm MAF, Smooth Bellows, and borla exhaust. What is my RWHP and what would that mean at the crank.

MAYBE 320-325 at the rear, MAYBE, you need headers and y pipe

typically what people use is about a 16% drivetrain loss. obviously, with lighter wheels, and driveshaft, those numbers will be reduced. So if you are putting down about 320 to the ground, then that means that you are between 350-360 at the crank. hope this helps
