Blower RPM Worksheet

[BOOOOST]

Here guys, have fun (click on the attachment below).

It's setup for Lightnings, but you can easily change the values. I noticed the Lightning at 5200 with the stock pulleys, spins the same as the Cobra does at 6500 with stock pulleys: 13150 rpms (approx.)

You probably all knew this though ;-)
