Multiply this result by the previous result and you get the number of inches per minute you will be going at 5000 RPMs. 1219.51 * 87.92 = 107219.3192. Multiply that by 60 and then divide by 63360 for MPH. ( 107219.3192 * 60 ) / 63360 approximately = 102 MPH.

Ok, now I have a headache.
I really can't imagine not going over 5000rpms.
