When **** hits the fan

In the past, people would just trash the pistons make up calling them ticking glass time bombs and junk. I haven’t had any problems with mine in years. Though I don’t push them like MPO does in racing often.

FWIW, I have used stock replacement hypers in my 2.6L Mitsu Starion rally engine, turbo'd to 14-15 psi, and putting out around 1.75 HP per cubic inch. Nary an issue, running a few thousand miles of hard rally stages on them, and spending lots of time at full boost, in all sorts of weather conditions.

The ECU would tell you when it detonated via the stock knock sensor, so it was not hard to avoid detonation in setting things up.
