you should post this question in the turbo/supercharged section, but you most likley have an alignment problem.

 

Your belt is touching the walls of the tensioner pulley. There should be some space clearance or else you get a frayed belt. Which side is the belt touching? Closest to the engine block or away from the block?

 

away from the BLOCK on the side of the s.c

 

What size pulley are you using? And if it is a smaller pulley than stock, did you shave down the mounting plate leg for clearance? Also, make sure the hose clamp on the drain back plate tube isn't touching the belt (rare but possible). What method are you using for adjusting/checking your belt tension? What belt (size/brand) are you using?
