Hi-Performance superchargers!

I'm looking to buy a new supercharger for my 1997 GTP. I found American supercharger on eBay. Does any have any experience with these guys? Are these worth buying? Any other sources for high performance M90's for the L67? Thanks in advance for any help! -D

I don't have any personal experiance with that company, but I can tell you that you can save a lot of money by not buying it from them. If you're looking for more boost from your supercharger, get a smaller pulley, preferably a modular pulley system from pulley boys or zzp. Other than that ported inlet and outlet of your stock supercharger will net the same results.
