69, thanks for the interest. We just bought a house so right now I am only in the early/research phase of which supercharger to go with when the time comes. I have heard really good remarks about the ATI Procharger and if I ever pick up the kit I may look you up! I have had a few people say it would probably add about 125 to the wheels. Not too shabby for 8 lbs of boost. That would probably put me around 375 rwhp overall. I just need to decide on whether or not to mod the 93, or just buy an 03ish Z06 in a couple of years and add some boost to that beast (Procharger or Magnacharger). Decisions, decisions.......Let us know how your buddy likes the outcome of his 89! ATI sent me some literature about, yep, an 89 'vette. Stock they ran 14.54 @ 96 mph; after the procharger was added, they gained 1.82 seconds and 17 mph in the quarter!!! (12.72 @113). WOW!!!
