I installed a lot of ProCharger kits, many of them in C6's.
The Gates industrial green drive belts are by far and away the best available, so if you have issues with belt slip/jump/failure etc I'd try the Gates green belt in that size before dropping the money on an 8-rib setup. It doesn't color match as nicely but most anyone with a big supercharger setup understands the green belts are the way to go.
On any Procharger setup, if you hear weird squeaking/whining pulley noises, take it seriously and after IDing the offending pulley (a *very* small well-placed squirt of WD40 can quiet a bad pulley bearing) reverse lookup the bearings used and make sure it's not some sealed bearing rated for a paltry 6000rpm or something like that when those pullies see 3x engine RPM due to the pulley ratios.
Had a LOT of problems with several ProCharger installs due to ProCharger not being able to do belt-speed based math and select correct bearings for the pullies and tensioners in their kits. Honestly ProChargers aren't my favorite centrifugal blowers.
If anyone else is ever in the market for a supercharger on a Corvette, and if my $0.02 matters - i really prefer the A&A 'flip kit' Vortech V1/YSi based kits and the East Coast Supercharging (ECS) Novi 1500 based kits.
The Edelbrock kits are very well engineered and tends to be one of the most trouble-free setups in Corvettes by virtue of an absolutely ingenious heat exchanger design that clears the stock hood, along with a very thin and easily installed Air-to-Water heat exchanger in the nose of the car instead of the bulky air-to-air intercooler required by most centrifugal setups like a ProCharger or Vortech.
The big advantage of the Procharger over the Edelbrock setup is being able to expand things later on. With pulley changes and a bigger fuel system you can run more boost and turn up the power on even those smaller P1SC head units and get to mid 650-700whp or so with all the supporting mods. The Edelbrocks tend to be in the 500-575whp range and are great as a 'set it and forget it' sort of build, but don't offer much in the way of future expandability when that starts feeling slow.
Overall your setup and Prochargers in general make good power and I do really love the power delivery of a big centrifugal blower. IMHO it's better for a street car because power is consistently and gradually rising toward redline with a good flat torque curve so it's easier to find traction on most city streets with sensible tire choices, vs 'all if it RIGHT NOW' sorts of power from a big twin screw blower like a Kenne Bell or Whipple. Turbos of course bring their own variables into play and because of packaging and cooling issues I generally don't like turbos on Vettes.
Regardless of all that, nice car and you owe us more pictures
Did you get it dyno tuned? What did it make and what else have you done to it?
