What is the calculation to figure out how much torque will be put on an axel? Moser's axels are rated to 5200 and I'm thinking thats not engine torque. I would like to see how much my car is making so I can do some figuring.
Its the one with tranny 1st gear, rear gear and engine torque.
I hope so to. I bought a 9in and pulled the axles and they measured at 26 1/8 and 30 3/8. So thats what I ordered. They are 31 spline to go w/ my detroit locker.
All depends if the locker is wider internally. Probably be alright. Usually run into problems when you cut axles for a spool, then go to a LSD or locker.
Steel, you won't break 31's.
350ft-lb x 2.27 (no units, it's a ratio) x 4.11 (no units, it's a ratio) = 3265.395ft-lb going into the axle.
It goes into it at a rate of engine rpm / gearbox gear ratio / diff gear ratio
So if that torque is at 4000rpm -
4000rpm / 2.27 / 4.11 = 428.738rpm at the axle. Which means in a manual transmission you need to have the axles spinning that fast to have all that torque going to it, otherwise it is going to be lost in clutch slipping. Which, with a 26" tyre is 33.15mph. Autos have the torque converter to allow the engine to spin to speed higher than the gear it's in, supplying more torque at lower rpm - allowing more torque at takeoff.
