What Are the Drivetrain's TQ/HP Limits
 
I searched and couldn't find any obviously no one intentionally does "failure testing" on their Evos.

That being said, AFTER the clutch, what components will start to fail when we exceed the stock torque & horsepower ratings by a significant margin? (Gonna get a 2.3L stroker; maybe go nuts on the turbo, too).

Intuitively, we expect things in the transfer case & transmission to start to break if we do a lot of launching with more power; but at what point does this really start to happen regularly?

What will the diffs handle?

What about the drive & half shafts/CV joints?

What do we seriously need to think about pre-emptively upgrading and replacing as we exceed 400 ft lbs, 500 ft lbs, 600 ft lbs, etc?

Safety, reliability, and weight are significant concerns.
