I'll find out! Traction is going to be the biggest issue and the hardest loads will be the launch and shift. The launch will be hand slide and no bar (is the plan) with the air shifter for the rest of the run will make very low stress spikes so we'll see if it will hold against the brute torque of it all. I've only ever broken one (at least catastrophically) and a few sheared off pinion nuts. The OEM gen 1 shaft is a weak link which was resolved with the heavier duty shafts. I quit running the heavy duty shaft after breaking a few engine cases which failed before the rear ever did.
