I need a short blower tutorial. Now I know what they do, I believe.
They ram more air and increase cylinder pressure, improving volumetric efficiency and power.
But what is with the pulley changes, what are you guys doing there and what are the positive and negative affects, and why.
Also why does it affect Inlet Air Pressure.
Thank

Glad to answer Jim,
The Short answer is this.
A supercharger is an Atmosphere multiplier, in its current configuration it takes Atomspheric Pressure all around us and boosts it up to about 1.6 times for a Gauge pressure of 8.5 psi
Turning that same blower faster with a larger 10% overdrive crank pulley can boost it 1.8 times or a gauge pressure of 11.5 PSI or more depending on pulley size.
More Atomsphere ( Air + More fuel = More Power )
