Like say you had a 1000 rwph car, you know that after every race something is going to break, whether it be a pulley, a piston.... basically like professional dragsters ( btw i know they have more than 1000 rwhp) Im jsut curious arround what rwph do things start to break i.e. 400, 500 600 700????

Your factory rods are rated to 450 HP, that's flywheel. You can go above it, but you're on borrowed time. Pistons and crank are close to that, but a little higher.

The block will hold more than that, I'm not positive how much though... I could imagine 500+ being ok.

Your transmission is next down the line to break, the T45 is rated very low, and you'll lose that... TR3650 is a little higher, but still only 360 ft/lbs if I'm not mistaken

You may lose the driveshaft around 600.

Your rear CAN give out on a very good launch (slicks) at 450 RWTQ but chances are you won't get that strong of a launch... carrier and axles will give out around then though... they'll be ok to higher... but agian, borrowed time.

That's about it for the whole driveline, and those are just my GUESSES, I can't say for sure on anything except the rods and transmission ratings. Point being: the factory stuff has different failure points, you don't hit one magic number where things randomly start to fail.
