i got a new gates belt when i changed to a 3.4 pulley. it slipped so bad the engine
was actually missing after 5,500 rpms, put the old gatorback belt which was stock
length (gates was actually shorter so not to slip) no slippage at all needless to say
i'll be using gatorback from now on.you can get the supercharger belt # GTR-4060663
and the primary belt #GTR-4060935 both from summit racing, just put in these #s,jimmy
