Some guys with early N54's had this issue... it ended up being how the car was being driven... or shall I say LAUNCHED!

Some drivers were launching so hard that the rear axle would "hop". This "hop" would let the front crankshaft pulley contact the radiator support... some belts would get shredded or cut. The fix was a new front crankshaft pulley which was not cheap! I would take a real good closeup look at your pulley. IF you have a laser pen... that might help see IF everything is in correct alignment.
