How much HP?
Monday, February 06, 2006 9:35 AM
Ok I want to get a few opinions on how much wHP I'm putting down. Here's the list of the mods.

Intake
AEM alternator pulley
Cat-back exhaust. Not crush bent
Magnaflow resonator
Magnaflow muffler

I'm guessing 142 at the wheels. What do you think?


Ps. I know there's no absolute HP for each mod I just want everyone's ball park figure.

Word. approx. 165BHP at the flywheel, minus 12% puts you around approx. 145 at the wheels.

They are right, what they were saying is its about 12% loss for a manual and like 16-20% lose for an auto.

Get to a dyno but, if I had to take a guess I would say 135whp. Most 5spd Z's put down around 120-125 stock. You have gained no more than 10 whp.

on a N/A car, its called an intermediate or B-pipe. its only a down pipe when the car is turbocharged


Some times the best way to get that tailgater off your but is to light a fart.
