which pully d1
which pully d1 I am picking up my d1 procharger kit and front mount Saturday. It is going on a full bolt on a custom cam 6 speed and 9 inch camaro. What pully do I need to run to end up with roughly 525 or so to the wheels? 8 or 10 pound pully?
Need to know what size the crank pully is to choose the head unit pully.
I have a 7.250" crank pully with a 3.7" blower pully making 10-11 #s of boost... 520rwhp, my car was tuned at 5,600 feet/elevation. You should make more power than me if your around sea level.

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.
Hopefully this helps. Bob
