Do you guys know what pulley I need to achieve 8 psi of boost on my 2001

camaro ss? I've searched and searched but it's hard to find out which ones

to order...So 6 rib what crank and blower pulley will achieve 8 psi? I'm about

75 ft above sea level(sacramento,ca)

I-forget the crank pulley size but the blower depending what u got d1/p1 would be a 3.8

any one? is 8 psi too much for a 6 rib set up?? I'm thinking I need the 6"(5.8) crank and possibly a 3" pulley? but i've been told 3.8" also

6" Crank and 3.4" Blower pulley on a P1SC-1 should net you 7psi on a stock car.

I have a 3.2" blower pulley already, would that produce too much boost with a 6 inch crank?

The 3.2 should be about perfect for 8 psi. With a good tune 8 psi is what I recommend going with. Bob

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.
