So many people think they understand nitrous. They don't.
Barrman is correct. With the proper controls of nitrous (most important), the octane, and the spark you can achieve bigger than average power gains.
Now having said that. I'd look to D for what the mechanical strength of the parts are. But at the same time just because parts failed does'nt mean it was a good nitrous / fuel / spark / rpm balance. Ramping nitrous for starters will go a LOOOONG way in keeping a motor together.
**if** you have it all balanced right your first failure would be a piston swelling and then scuffing / sticking in the bore.
Quite often people break rods and think it was too much power. Well.. you gotta define power. Rather I suggest it's huge leaps in power transitions that break rods. Not simple shot size.
