1. Take a 500+bhp boosted motor with stock cast pistons.
2. Like an idiot, run that motor in full boost for an extended period of time at a very high rate of speed.
3. Remove pistons/rods to discover 4 if them are completely fine.
Of the other two, one had a cracked ring/land (but oddly enough, not the first compression ring, only the second) and the other one had actually been melted on the exhaust side. I have no speculation as to what caused it because I know exactly what caused it. (this was the old engine that made a mere 453rwhp)
