There is no definite limit to the amount of torque that these transmissions can handle. HP doesnt break anything, torque does.
That said, there are rough estimates of where the stock transmissions are rated and it tends to be in the 400+ Tq range. It could last years or not even a month, it'll fail when it wants to fail.
Best you can do is make sure the OD unit is properly serviced and you have a good clutch.
