you have a 2001 Focus with only 33,000 miles?!?!? or is that how many miles are on your supercharger? and do you have the BBK or an underdrive pully? and i see you have nos. so if im not mistaken when you really get into it your RPM's probably start moving up pretty well. could be whats putting the after effects on your JRSC. but its hard to understand what your issue is. are you saying the part on the Super charger itself broke a stud? the pully part of the supercharger? it would be best if you could post pictures of the aftermath!
