How much boost should I be making? P1SC-1, stock LS1 w/ blower cam.
Just curious about how much boost you guys think I should be making. I'm new to Prochargers in general and just bought a car.
00 SS-
Full boltons: long tubes/ory/cutout/catback
Thunder Racing "TR Blower" - 214/230 .601/.579 117 LSA
P1SC Procharger /w Front Mount intercooler & red Race BOV
LS6 Intake Manifold
6 rib setup with the stock 6.XX crank pulley and a 3.25 blower pulley. The boost gauge runs right up to 6lbs at 6200rpms. I'm about to order an 8 rib setup and a meth kit to try to find some more power but I want to make sure that ~6lbs is where this should be at. It seems a little low to me, but I know the engine should be a good bit more efficient than a stock setup. I replaced the belt when I got the car and I have it pretty snug. Bob@ brute speed said "guitar string tight," I have it pretty tight but not LITERALLY that tight.
Thanks for any input!

I have a p1sc1 and on the 6rib yet with the chevy Chad mod and I'm seeing 4psi at 5200rpms. That's with a 3.85 blower pulley I wanna get a 3.2 or a 3.1 and try to get 10psi out of it. I think with that 3.2 u should be around 8-9psi

How much boost the blower can produce depends on many variables.
* Cubic inch. The larger the engine the less boost it will make with a supercharger.
* Headers and exhaust. A better flowing system will produce less boost, requires a smaller pulley to regain the loss in boost. Ultimately though, more power will be gained.
* Camshaft and heads. A camshaft with some overlap will leak out some boost through the valves. Better flowing heads react a lot like a better flowing exhaust system.
* Altitude. Elevation plays a big part in how much boost is produced. Those people living in the higher elevations have to spin the blower harder to see boost.
* Condition of engine. An engine with real good sealing rings will ultimately produce more boost than one with worn rings.
* Rpm. An engine that is spun up higher in the rpm range will normally produce more boost.

Thanks Bob, this is the p1sc1. I found a spot was a vacuum cap was missing and it's now a little over 7lbs. I don't think the belt is slipping either. And im about 2200'. Thanks!

You're welcome, your elevation is putting a hurt on the boost, 7 psi isn't bad at all for your combination. Bob
