How much horsepower for light mods

[no_se7en]

Hey Nico, I recently bought a used Z TT 5 spd not so long ago almost stock, had about 3 simple mods in it. Had some suspension problem but it was on another thread......The mods are an aftermarket K&N cone filter, megan racing downpipes, and megan racing exhaust w/ 3 inch piping from catback. Never took it to get it dyno'd but just wondering how much horsepower im pushing on top of the stock horsepower??

Stage 2tt, probably about 320 bhp at stock boost.

Only if recently rebuild. Old motor = loss of compression = loss of hp

At the crank that is. And running 2.5" TPs to a 3" CB will hurt numbers instead of helping. Really unless this TT is pristine with something like 30k miles youre looking at 300 chp or around 255whp and thats at 15% drivetrain loss which is VERY conservative.
