I was looking at SteVTEC's graph of acceleration g's vs mph showing optimal shift points for a 2K2 Max. It showed going up to 40 mph in first @6600 rpm. That's a huge load of torque going thru the drivetrain. Any idea what it's limits might be before it splines?

 

if you are talking about physically falling apart at one time, much more than you can ever make that VQ put on it. but over time axles, joints etc will degrade. but for it to snap at once.. well.. unlikely.
