Its not really about the boost. Its really about the power created and the tune.

If you have ZERO knock and you are making say 550hp it might last for a good while. On the other hand if you are making 450hp with spark knock occurring frequently well then it ain't gonna last long.

Boost is just a measurement of restriction....
