JRSC squeeling at high RPM

[JRSC2001GSR]

My supercharger just started this tonight. At around 5,500+RPM my supercharger (or belt) is making a really loud screeching squealing noise, it's not peircing loud just loud. I think the belt might be slipping, although the belt is still tight. What are your opinions? Also what is the JRSC stock belt size, 620mm?

Do a search.

1. The belt is loose.
2. The belt is worn.
3. Search for the size.
4. Something else is screwed, in which case figure out what and post it up.

Welcome to the board! As you have noticed, SEARCH is the thing around here [img]smile.gif[/img]

I just went through this. I tightened my crank pulley to alternator belt a bit, even though I thought it was tight, and it helped for a day or two. Squealed again, so I replaced the belt. No more squealing. The belt didn't even look that bad, had some cracks across the ribs here and there, but that's about it. If you're losing boost pressure up top with the squeal something is loose or slipping.
