Default HELP NEEDED C5 procharged vette

Okay so i have a c5 vette with a D1 procharger. All the pulleys are for an 8 rib belt but when i got the car there is a 6 rib on it and its eating away on the one side. i checked the alignment and its off so i know that needs to get fixed. The engine is an Ls6 fully forged its at around 600hp now. My main concern is, is the belt going to slip from the power?

Put flip drive on it. Only one way to make sure on the alignment.

Regardless of what you do you need to fix the alignment anyway. Then if you have slipping, go from there.

I had to get a laser alignment to find the issue so it could be fixed

good luck

It is odd because on the procharger pulley the belt is pushed all the way towards the engine side and on the alternator side the belt is pushed toward the nose of the car on the pulley. The only thing i did so far was order a new alternator pulley just because it was a little rusted, but should i take the procharger mounts off and get them shaved the 1/16th of an inch so the procharger sits back a little bit?

Amazon sells a gates laser alignment tool. Pretty cheap from what I have heard. Also get a flip/direct drive.

buy the gates laser and make sure it is properly calibrated, there is a really helpful thread in the forced induction forum on how to properly calibrate the laser... once that is done then check the alignment of your pulleys... I had a horrible experience installing my d1sc but I learned a ton, if I ever have to do it again I know what to look for and how to fix it... my belt was trashing itself just idling, the pic below is what it looked like after running for less than a minute!... my blower pulley was 1.5 ribs out towards the front of the car which was causing it to walk off the pulley and shred the belt... turns out that my kit is 8 rib compatible and there should have been a spacer behind my blower pulley since I am only running the 6 rib at the moment, but that spacer wasn't there to begin with... after getting the proper spacer everything is spot on and it runs perfectly, no belt dust or anything... hopefully your's will be a simple fix as soon as you spot the problem
