INDY/RHS heads

The question revolves around how much heat is wicked away from the actual instantaneous combustion temps. If those are not lowered around the peak, then there is little to no real torque or power loss.....in thermo terms, the PV curves does not change, where it counts. And if the loss is late in the cycle, when instantaneous pressure are way down, the effect ought to be minor. The head material an get the average heat away faster and thus lower the head surface temps, and raise the cooling system temps. But that does not automatically mean the actual combustion temps drop and pressures in any significant way. Perhaps a good way to figure this would be to measure exhaust temps.....that would be interesting.

Coated chambers...... damn you..... Now I need to learn more stuph! LOL Tnx for the discussion and the simulation to think. The education continues....
