Default Calculate blower rpm's

Anyone got a link to calculate a blower's rpm's or even the formula?

Specifically procharger D1SC.

Thanks in advance.

lower crank diameter / blower pulley diameter * Engine RPM

7.25 / 7.65 * 6000 = ~5686 Blower RPM

You'll probably want to include the internal step up ratio of the blower if you want the real RPM. The D-1SC has a 4.10:1 ratio. ie: In the example NWDragRacer posted the blower would be running at a little over third (23,313.xxx) the D-1SC's 60,000 max rpm.

Good luck.

Yep got the internal step-up figured in too.

Thanks
