So what is the limiting factor in terms of torque/horsepower holding capacity? Is it the shaft(s) that run into the quick change gears at the back? I have seen a limit of about 1500hp for these... What alloy are those shafts? Do you make any in maraging steel?

I would love to have a quick change for my vette, but I am sure I would break one...
