"Held" meaning past tense, so its blown up by now? Detonation is not the only reason for failed ring lands. Materials exceeding their designed power goals will make them fail.

boosted EJ engines require aftermarket pistons at 400 due to non forged internals and thin ring lands

Ive yet to hear on here of a aftermarket piston ring lands cracking. My SR running Wiseco Pistons see a fair share of high 80's knock, been running like that and drifting it for 3 years with no issues at all. Just needs a retune.

Companies could save money and material if they could use thinner ring lands. But they cant cuz a thicker ring land is required to withstand the power.
