There are so many factors to consider, you can't just throw out an obscure number and say that is the failing point. Heat and oil starvation are ultimately the biggest enemies, which has more to do with the tune and how you drive it..

You could probably make a single dyno pull at 500whp on pump gas and not fail, and you could probably drive the car balls to the wall 24/7 at 250whp and throw a rod. Hell, people have blown completely stock engines..
