P1SC with bolt ons, how much power?

I bought a used Procharger to put on my C5 Corvette. Currently it puts down 400/360 at the wheels and I am about to slap this baby on and run 7-9 pounds of boost (stock bottom end). What do you think the results will be? Local shops (they would know better than me) say only about 500 but I was hoping for around 550. I hope to gain more than 100 HP but I have been disappointed before. I am setting myself up for that again?

Car currently has LS6 intake, cam, L/T headers, GHL exhaust and an U/D pulley.

I am not sure what kind of numbers you will end up with. But I believe a procharger and a new tune should get you the 100 hp your lookin for. Good luck and congrats on the procharger purchase

Depends on the cam/heads. I'm running a mild cam 216/220 Comp cam with ported heads, long tubes, no cats, and dynoed at 561/490 with 8psi. Good luck

Those are similar to the numbers I would hope for. Stock heads but I think I may be getting some of those too... Are yours ported LS1s?

Yes, cnc ported. With that cam, the car feels about the same as stock until you drop the hammer.
