I meant on a stock engine.
Procharger has been around for a long time and make serious power on a lot of cars.
Even the tuners that totally redesign Procharger systems to improve them have said the new Procharger system is good.
I just would like to see centris deliver a dyno that looks almost like a positive displacement blower or twin turbo on a 100% stock engine.
I know it can be done because tuners have modified centri systems to do so on a stock engine.

Tuners have added a restriction plate to the system to produce more boost sooner, with centrifical superchargers. What this does is to make the blower work harder than it normally would, but whenever you work a blower harder you are going to produce more heat. Some have claimed that the restriction plate works, but we haven't seen a reason to use one at EPP. Bob

With the plate, they are making power EARLY, almost like a positive displacement blower. On the street, low/mid RPM power is crucial.
I am really interested in the idea about IAT's. It makes sense. What data do you have to support this? It's not that I don't believe you.
It makes sense. But, I have not heard owners reporting elevated IAT's.

No upgrade yet for an even larger intercooler. I don't have any numbers yet on how much horsepower the ProCharger front mount can handle. It is going to take a built engine and a lot of boost to find the limit to this intercooler. Bob

No reason?

It makes sense. But, I have not heard owners reporting elevated IAT's.The reason I say I feel there is no reason to use a restrictor plate is that with 500 rwhp on tap, it is pretty easy to fry the tires as is. On street tires traction is a big problem without a plate, I just see a plate as a way of further reducing traction.
You won't find a lot of information regarding the use of restrictor plates, here is one link from the GTO Forum. http://www.ls1gto.com/forums/showthread.php?t=168775 Bob

Man I'm glad to see this, I didn't want to go PD on my SS when it gets here. I feel that with the big 20" wheels I didn't want the insta torque that a PD blower puts out on the street. I would rather have the boost come on a little slower since this isn't going to be a dedicated drag car. Bob if my car had arrived I'd take you up on the install. I was really hoping to try to squeeze 600 RWHP out of my stock LS3 with H/C, Exhaust & BOOST, maybe a little meth too since I have 2 other cars with meth injection. A stock SS will fry the stock tires on the street, so no need for the extra torque down low IMHO.

We have kit from them on my freind Truck (Denali 6.2) and when he got hot a tuned denali beat him badly.
we changed the air filter location and it is a day n night diff.

bob the graph is awesome. the only thing that really turns me off is what is with the 6200rpm? i think if that graph continues like that to 6800 i would replicate the same exact setup. what cam is that? is that f1a on a 402? psi? what gear are you running on that setup? its so purty i need info

Thanks! We basically just took a snapshot of the dyno graph up to 6200, as max rwhp had peaked. That doesn't mean that you can't continue to rev higher before you shift. We do our dyno pulls in 4th gear, and since the numbers had peaked we cropped it at 6200. Bob
