im gonna put a 3.5" pully on my supercharger what size of belt can i use or do i use the stock size

 

[jacobmh27]

you do need another Size belt I know there is a size chart on this site somewhere but you need to make sure you have supporting mods and Scan For KR after install

What mods you have? I doubt a 3.5" pulley will make your stock car faster.

And might hurt a lot

Get a PCM. You'll need a tune and a 180* T-Stat IMO.
