Hi!

I have two issues with my Procharger Supercharger kit.

1.
The belt squeals at startup. I have recently changed the multi belt to a brand new one. But it squeals more than ever. Stops after about 15 seconds after startup. Here is a clip of the squeal, but this is an old clip, it lasts longer now. https://www.youtube....h?v=6tyfjKAH9DY

As you can se in the comments, someone writes that I should "change the two small pulleys". Exactly which pulleys is he referring to? See attached file (not my car). Can this be the issue?

Could the belt be too tight or too loose?

2.
There's a rattling noise from the supercharger unit on idle when I have driven it for about five minutes and then let it go down to idle. The rattling sound is not there on idle when I've just started it up, only when I have driven it a while. My dad thought it might be the bearings in the pulleys with "teeth", that drives the supercharger.

Here is a video clip: www.markusp.se/download/procharger_bearings.mp4

Help much appreciated!

Rattling is normal from prochargers, mine did it a little bumb up your idle to 1000 and that will solve that.

As for belt squeal if its not constant I wouldn't worry about it as much, now if your not hitting the boostlevels you should be i would tighthen the belts and see if that helps.

 

Yes, some rattling always comes with a SC, but this kind of rattling I've never heard before.

How do I "bump up my idle"?

No, the belt squeal is not constant, but she screems like a stuck pig on startup, pretty annoying and sort of embarrassing among people, haha...

 

You can bumb up your idle with uprev, tighten up your belt untillb it doesnt squeal or try to find the culprit and see if that pulley/item is hung up.
