I didn't open the file above but here is what the formula should be for a Procharger (or other centrifugal with an internal step up):
Impeller RPM = (Crank Pulley Dia / Blower Pulley Dia) * Internal Step Ratio * Engine RPM
Step up and max RPM per model can be found at ProCharger Supercharger Models

Yea I've got a spreadsheet just not on this computer.
I've got it set up so I can compare blower speed for multiple pulley arangements, multiple blowers and at 50 engine rpm intervals all at one time.
Hey sharpshooter, if you've got belt traction, take that d1sc to about 107% with some C16 and crank the meth all the way up. Lots of Power!
