How much HP can a stock non-turbo 2 gen diff handle?
Tnx in advance

 

Depends on how you treat it, your mileage may vary, and all that. ITS roadracers snapp Torsens on occasion at less than 200whp. But they're getting abused pretty good and aren't as strong as the stock clutch type. I've snapped axles at the drag strip at around 260whp but not diffs. I would guess though that given enough trips to the track the diff would eventually break.

 

i got 477 rwhp but so far i've been very lucky on the axle shafts not breaking (aftermarket). Mabey it's time 2 go 4 a whole aftermarket diff. Any suggestions?

 

It is torque that breaks rear ends; not hp.

How sticky the tires are; what type of tranny is used (auto vs manual) , weight of flywheel, and style of launch all effect the life of the drivetrain.

 

sounds like you have a fast ride.... I would start looking for an '86-88 clutch style Turbo 2 diff with matching halfshafts. There are a few guys with SBC/NOS running mid 9's on them with no failures with automatics. Do note that the pinion flange on the T2 is different than the n/a pinion bolt pattern. Meaning the driveshaft will need to have a new flange put on it.

Manual transmissions break parts.... autos are much easier in a drag application.
