Driveshaft RPM @ 120mph
Ok, Thanks for taking a look.
I am not the best with transmission gear ratios and such, I know what they are but trying to figure out what the rpm would be of the drive shaft at a given speed is making my head hurt.
Ok
S5 TII Rear end
S5 TII Trans
S4 Vert Rims
205/50/R15 Tires
Just need a good rough number of drive shaft RPM @
@50mph
@75mph
@100mph
@125mph
If you are wondering we are working on a Hybrid Electric setup, with regenerated braking.

its supposed to do that
5280 feet in a mile (63360in)
The rolling diameter of your tires gives you a certain number of revolutions per mile. The ratio of your rear end will change that to driveshaft revolutions per mile.
(Driveshaft rev's per mile) x (miles per hour) = driveshaft rev's per hour
(Driveshaft rev's per hour) divided by 60 (60min in a hour) will give you driveshaft RPM.
You should be able to take it from here.
