how much hp am i putting out?

i have an 03 lancer oz. it has: cold air intake, exhaust, t25 turbo, blow off valve, with intercooler.

Hard to tell.... dyno it

You have 120 hp stock so I would say add up everything you added to that....

i would say around 175hp whp btw 120 stock is at the flywheel not the wheels u need to subtract the rest of the drivetrain which is 15% for manual and 20% auto trans
