supercharger pully?

[gtp_80]

I have a stock 04 GTP 3800. i was thinking of changing the pully on my supercharger to a 3.4" but i don't know if it will effect anything else that i would need to change out also. does anyone know?

I know a lot of guys running the 3.4 SC pulley on the '04 GTP. You don't need a re-programmed PCM either. Its highly recommended to go to spark plugs that are one range colder just in case you get knock retard (KR).

The same principles apply whether you have the Eaton M90 Gen5 or Gen3 supercharger in a Series II or III 3800 engine. Thats includes running a Goodyear Gatorback SC belt. Good luck!
