100 ft from my house (lucky) idler pulley(I think it is called) ripped apart, $30 steel dayco and put my stock belt(supercharger) on ,back in business .Waiting for my gatorback 715 too come, funny thing was I ordered it yesterday and today BAM! i NEEDED IT.My stock SC belt doesnt cause any slippage though.

The tensioner for the */C? I have gone thru 3 or 4 of the 3.0" grooved pulleys for my */C, and I am getting them from NAPA :?

If you are having issues with pullies.. (both of you)

I'd suggest replacing all the pullies on that belt path. Might be another pulley causing exess stress and wiping out other pullies.

This is my only issue so far, maybe I could do tensioner also (plastic crap) but I ignored the chirping sounds of my idler that told me it was going so my own fault.

I happened to do all mine while on a rampage and figured they had 14XK miles on them. Of course..one new ribbed one on the front of the car let me down in record time.
