2nd gear is notorious for shucking teeth during a power shift in the 915. Big turbo torqe can peel them off even after the clutch is fully engaged.

400WHP will break every gear in a 915 and bust the housing as well. At that point it is past questionable and a firm given that you can bust the tranny at will.

300 ft/lb is the limit of what the 915 can take long term, and at that you have to treat them with respect. I've seen one 915 grenade with a 225CHP 3.2L Carrera engine behind it during a burnout "demonstration". It was the cool $1000 set of black marks though.
