If you were to disconnect the driveshaft to the front diff. would you still have 5-40% attempting to be sent to the front wheels under rear traction loss?

On the 2wd dyno is 5% always being lost from the rear wheels?

Must you change out the ecu and transmission of the 996TT to that of a GT2 in order to get 100% rear wheel power?

I very interested in the first question as the answer should help with the other two.

Thanks for your help,
Rick

 

The transfer is mostly mechanical so...if you disconnect the fron diff it should be pure RWD
PSM might still limit power and brake individual wheels if slippage is detected

 

Probably won't work very well with the PSM system.

 

Thanks for the reply's. I forgot to mention this is on my race car and the PSM has been removed and no longer is part of the equation.

I just don't know if the ECU will still try to dictate 5 to 40% to the front even though nothing's there.

I have heard that the system is mostly mechanical but does that mean there is still some loss?

Thanks,
Rick

 

Go Rick!

 

The torque is transferred to the front axle by a fluid coupling. The difference in speed between the front and rear axles determines how much torque the front gets. If the front driveshaft is disconnected, the output shaft from the fluid coupling spins freely, and there is no slippage in the fluid coupling.

 

Thanks ebaker for the info. Has anyone disconnected and driven their car in this fashion? Anyone track one with the driveshaft disconnected?

Great forum!
