Hello, long time lurker here finally decided to signup, glad to be here in what seems to be a pretty friendly community here. Being a long time Pontiac fan and driver I bought a good condition 2002 GTP Fully loaded. I had since done several modifications however, no easy access to a dyno make me wonder what kind of power I'm putting out with my current mods. I understand that there are many many variables involved which makes it difficult to estimate power without actually dynoing the car but I was hoping some of you guys might be able to give me a rough estimate of how much horsepower and torque I might be making at the crank.
Wizaired Cold Air Intake
ZZP 3 inch downpipe with High Flow Cat
ZZP PCM tune
3.4 Inch Pulley
90,000 miles on car, well maintained, always had synthetic oil
I'm certain I have some knock since I'm running the stock ac delco plugs and thermostat, but I have some more supporting mods on the way like a 180 thermostat and some autolite 104's. I'm curious how much power that might add as well.
