You might have to run a smaller pulley to make the same HP at altitude though...
Besides, it isn't the rings. The failure in the pics doesn't support that theory.
If it were the rings butting, there would be seize marks all over the cylinder walls since the rings ends came together and bound up on the walls causing the lands to crack.
It's a detonation failure. Oil in the cylinder, going lean at WOT, bad tune, low octane, etc, is what everyone should be more worried about.

Obviously you don't understand what a dyno correction factor is. Dyno tests on supercharged cars done at high altitude can inflate the numbers pretty noticeably when the CF ends up being 1.15 or worse.
Also the guy that I quoted did not break his engine. When he said that he was fortunate that his ring gaps were .015", it's pretty obvious to me that he meant he was fortunate not to get one of the cars that come with .007" gaps. And I agreed with him.
