Your question is very vague, hence no responses.

Speed of the blower pulley is very basic maths.

ratio of crank/blower x engine rpm


eg 8" crank / 3" blower x 6000 rpm = 16,000 blower pulley rpm

Or is there something else you needed ?

Don't forget any internal step up ratio of the blower. The impeller shaft gear is smaller than the input shaft gear to get the speed up to the high RPM.

Crank Diameter / Head Unit Diameter * RPM * Step up ratio.

I don't know what the Novi 1500 has for a step up ratio though. I would expect Paxton to provide that info to you.

I didnt forget. He never asked about compressor speed. He asked blower pulley.

Although that is the vagueness I mentioned.
