rpm quest

http://www.coastdriveline.com/htmlfolder/calculator2.html can i use this calculator to figure the rpms on my ranger or will it not be right?

the only thing i dont like is that it doesnt take what motor you have in consideration.

a 4.0 would have less rpm at say 60 than a 2.9 with lets says 3.73's.

As long as the gears are the same it doesn't matter what engine you're running. A 2.3 @ 3000 and a 460 @ 3000 rpms are going to be going the same speed if the tranny, tcase, and rear end are geared the same and voth vehicles are running the same tire size. The calculator should be good.

I stand corrected.
