I've had a procharger now on my LS1 Vette for about 3 months and I'm having some belt squeak issues. Spray some belt dressing on the belt and it goes away. I'm thinking that the belt alignment may be off slightly and I would like to hear from some other Procharger owners and get some input. My kit is the latest one from Pro-charger P1SC-1. I know there are other people running this kit without the belt noise so I would like to hear from them and what they did to fix it? Thanks in advance.

 

im running the d1sc, and when I first installed my kit i did not put my balancer on all the way and I had imidiate problems with my main serpintine belt jumping off the pully. have you retentioned your belt since you installed the kit? the belt will stretch very quickly when its new. I would verify that your making the proper amount of boost, good sign that the belt is slipping.
