It should make an easy 700 rwhp on 93. The 2650 makes WAY less heat than the stock blower. Even at 15 psi you'll be 30-40 degrees cooler than the stock blower at 9-10 psi. You will loose some torque below 3000 rpm because of the way it ramps boost in. By 4500 though it will be up at least a 100 lb/ft over stock. I think it makes these cars way easier to drive on track. I can post up some dyno sheets when I get back to the shop on Monday if you're interested.

Thanks for the info. I have a question if you don't mind my asking. I trust you guys know your stuff. Is it safe at that psi and up to 6800 RPMs? Are you sending them out the shop for DD use at those boost/HP/RPM levels or are you dialing it back a bit. Those numbers look really good to me and if I can get there this way then that might be all I need.
Sorry to hijack the post OP.
