A friend of mine who owns a 1988 Monte SS has done that supercharger swap onto the LS2 that he installed in the car a few years ago. The car was tested at 392 RWHP before the supercharger install, and once he got the blower on and all sorted out, the car was tested at 652 RWHP. His build thread is over on MonteSS.com.

Don't spin the 'charger too fast with little pulleys. My buddy with the ZR1 cooked the bearings in his 3 times trying to get boost out of it. I think they're safe to about 15psi. Things go south above that.

LSA? Did you grab the one with the T6060 that was on EBay just before Christmas? I had a covet problem, but the cost decided it for me.
