It may be fair to say that if you see no specking that there may of been no detonation. But if all the combustion surfaces were really clean and fresh its possible that you may see no evidence of detonation specking.


It seems from alot of what was posted is that those stock Hemi pistons have a very thin ring land at the top. And ring land breakage is a common problem with foced induction even at mild levels.

As Dram/Dan stated hammered bearings are also a sign of detonation. But like you said you may of unintentionally exaggerated that.

Detonation because it happens at the piston will sometimes beat up the piston at the wristpins also if it doesnt break the lands or piston face first. But it will and can carry its force all the way to bearings too.

Im not sure you have a Det problem, I think its the OEM pistons and boost. But I wouldent rule out the det completly just yet.

I look forward to the pics of the undamaged pistons. mike
