Reply to "How to increase the power handling of a ZF? (850 newton/meters or 627 foot/pounds)"

Peter,

You're assuming this damage was due to too much torque for the ZF to handle. Perhaps the person who rebuilt this particular ZF didn't know what they were doing. Perhaps the R&P should have been replaced when this ZF was rebuilt. There are too many variables involved to simply blame the design of the ZF.

It's my understanding that most ZF failures occur in racing situations and involve broken input shafts on cars with slick tires. On a street driven Pantera, the tires limit how much torque can be transmitted through the transaxle. A 950 Hp motor will simply spin the tires under full throttle.

The best transaxle option for you, without spending $$$$$, is probably a brand new RBT ZF.
