Hey TBatt. You can also consider changing the vortech pullies on the supercharger side instead. The majority of the slip occurs on the serpentine side. I proved this out on the dyno with some belt grip dressing. The 8psi pulley is not only bigger but it is blasted so it grips better and has better belt wrap. Also, a vortech pulley is $90 where the 9psi stillen pulley sells for $200.

Just food for thought.
