hey O4redline, quick question for you.

The math used to calculate the RPM's of the supercharger uses the length of the belt right or at least the crank pulley diameter....since ours do not have any accessory pulleys such as air conditioner pulley would it change the math?

Just curious, if you would calculate the eaton's rpm the same for both vehicles

It should just be the ratio of the circumferences unless the belt slips.  Since circumference is diameter times Pi, Pi cancels and it becomes the ratio of the diameters.

RPM blower = RPM crank X (Diameter crank pully X Pi) / (Diameter blower pulley X Pi)

RPM blower = RPM crank X Diameter crank pully / Diameter blower pulley

RPM blower = 7200 RPM X 6" / 2.7" = 16000 RPM

That's assuming that the pulleys are exactly 6" and 2.7".  I have no idea what the actual measurements are.

wow thanks!

This is useful for belt/pulley calculations.

You will need to click on the file paper clip, open or save the image, then zoom in to see the formula.
