You can only get so much phase change cooling before you get the fuel wetting the cylinder walls and killing power. I think the boost pressure is a more important value since his static compression ratio was meant for n/a oeration. Crank up the boost enough and he'll have an intake charge temp rise that no extra fuel and meth will cool.
