How To Determine Procharger Rib Pulley? I bought a D1 and was wondering how I determine how many ribs it has. Do I count them all or just the inners? It has 6 inners. Also what pulley determines how much boost?
Thanks

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 blower.
* 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.
