So with this explanation, does that also mean because of a "faster burn", timing can be dialed back?
I was mentioning to 383 last night a question about thermal coatings interfering with the heat absorption based on the earlier explanation of the nearby surfaces cooling the fuel air mixture preventing pre ignition. Seems to me if coating reject heat from being absorbed by the piston, etc, the coating would also retard heat being absobed from the mixture.
In a word, yes. Some of the people I learned from are big believers in mirror polishing over coatings. Whether one is better than the other, I do not know or really even care. Reflecting the heat back into the combustion area helps push the piston down rather than being absorbed by the cooling system. Because there's more heat it burns faster so less spark lead is needed for ideal burn. Less spark lead and the engine doesn't fight itself quite so much and it frees up some power.
