Just wanted to take a moment and share some of the recent results we've had installing the Procharger kits on several of our customers C6 Corvettes.

We've done several other C6's with Prochargers recently, but these give a great representation of the different combinations that we're putting together.

If you're interested in more information, please give us a call at the shop (281) 870-8787 and I'd like be glad to work up a package for your specific application.

As always, thank you for your time and consideration.

Sincerely,

David Coates

Car One/Graph 1 is a stock 6-spd C6 with Kooks headers, off-road X-pipe, MTI tuning, stock cat-back and Procharger D1SC making 10 - 11 psi of boost.

Result: 606.2 rwhp

Car 2/Graph 2 is an automatic C6 running Kooks headers w/ cats, MTI Stealth 2 cam, MTI tuning, Corsa cat-back and a Procharger D1SC making 9-10 psi of boost.

Result: 605.6 rwhp

Car 3/Graph 3 is an automatic C6 with a Procharger P1SC making 7-8 psi of boost, Corsa cat-back and MTI tuning.

Result: 495.6 rwhp

Dyno Graphs will be posted later tonight!

WOW!!! Certainly a way to keep the targa and get the HP too!!! What would a 7-8 psi boost installation cost? .... in California smog test passing configuration?

Impressive results!!! Care to share the specs on the MTI Stealth 2 cam? How much rear wheel gains on the cam alone...I'm in the market to add a blower friendly cam on my P1.

torque looks good on those, but I would've expected more h.p. from the big boost #'s... pulling out alot of timing because of the high boost vs. C.R.??? would not think twice about it but my car made more hp at 5.5psi (620rwhp), however not as much torque (518rwtq)... Obviously my car is set up different P1SC and different cam + fast intake and different dyno different conditions bla bla bla, but I just expected more h.p. at those boost levels. Any alky injection on these???
Sorry for all the questions...

Sure! The cam is a 224/220, .581/.581 on a 116 LSA. Very smooth idle, very easy to drive ...... you should see an additional 30 rwhp or so from the cam swap.

Another cam that I've had a lot of success with on my blower cars is a modified version of my G1 cam (228/232, .588/.575) but on a 115 LSA. A little more aggressive but still very driveable and enjoyable - you should see approx. 40 at the tires from that cam swap.

If you're interested, give me a call at the shop (281) 870-8787 and we can discuss in more detail.

Great numbers from your combination! We generally keep the timing and cam selection pretty conservative and don't use alky injection. Normally don't see much timing (if any) being pulled out either while monitoring during a run.

On the C6's we've generally found each lb of boost to be good for 20 rwhp (give or take a little) so the numbers we've seen from these combinations are right in line with our expectations. Sounds like you've got a really strong car there making that much power at 5.5lbs!

All the best,

David
