Here's some general guidlines for driving. If you race heavily and are a very agressive driver who routinely breaks the speed limit by 50-100mph+ then the numbers may be lower:
Now I've seen 99 GT's survive on 500 rwhp and low 600 rwhp GT500 lose connecting rods. When you nearly double the rear wheel power of a motor than you don't have the safety factor anymore. That means bad fuel may do you in.
