Question about pulley size? And mods..

**KoldAsIce** · 09-22-2013

Hey guys I'm not new I have a 01 GP GT but tomorrow I'm picking up a 97 GTP.. It's got ZZP wires, Autolite 104s plugs, ZZP PCM, I believe a W-Body intake, Downpipe I think 2.5", Res delete, High flow cat.. Rest is pretty much stock! NOW I know about GPs but I'm gonna be honest so I don't eff nothing up I don't know much about superchargers I was wondering what size pulley I can drop to SAFELY for a little more HP.. I'm gonna get some headers I think just gotta wait a little other then the pulley what mods would you guys suggest? Thanks!!!

I'm gonna pick up 2 aero gauges before anything but I have a ODB2 adapter with Torque for now... I was just curious what I could get away with BTW how much HP would that add give or take?

i suggest you do the headers and a 3.4 pulley along with the tune at the same time.

well i went with a 3 in dp and a plog. im running a 3.6 and dont get any kr. I noticed a pick up in power idk how much but its a decent amount for the cost

Yea good thing is the kid I bought the car from kept the original PCM so I can just get it modified when the time comes and have no down time.. And with headers you can drop to 3.4?
