I can make a pass on alcohol, and when I get back to the pit I can put the palm of my hand on the front of a cylinder head. Based on that, I am guessing the EGT has got to be significantly lower on Methanol than gas. I could be wrong, because I know much of the cooling effect of methanol takes place during the vaporization on the intake side.

Injected? On efi we run lean enough at idle that it will build heat as much as we want. No milking of the oil with the vacuum pumps help too. We really use very little fuel.
