Turbo-6, did you add any form of piston of themo cooling?
I remember a few years back where a turbo flathead equipped streamliner got to some ridiculous speed on their first full pass only to loose the engine.
As I recall one of the pistons melted through, and the other 7 had metal movement.
From what I could see (parts laid out on a table after teardown) it appeared the damage was centered in the are of the piston directly over the connecting rod.
I expect that was the thinnest part of the crown (it usually is) and additional cooling may stave that off long enough to complete the pass.
A thermal barrier on the crown might help as well (I have no idea if the pistons I saw had such a barrier).
Just curious if you have found any of that, and what you my have done to prevent that (if it's not a secret
).
