Kyle:
**Back on the subject of CHT's, detonation, etc. If I am understanding correctly, CHT's are primarily a function of internal cylinder pressure (which, in turn, is influenced by the timing of the combustion event), but detonation margins are more heavily influenced by IAT?** Sorta. CHT's are function of heat IN and heat OUT. Heat IN is a function of ICP. ICP is most affected by timing and mixture (mixture afects the EFFECTIVE timing, or the thetaPP). Heat OUT is a function of baffling and OAT. Detonation margins are affected most by the combinations of fuel octane, CHT, and IAT.
