Consider
that cylinders that run 50d cooler - - can make more horsepower
than the
cylinders running 50d hotter.
Better volumetric efficiency.

And the measure of that would be????????? Scott
The measure is "manifold air temperature". If the manifold air temp
is lowered 50 deg F, then the power would increase 5.8%. That is of course
if the proper A/F is maintained. I believe there are to many variables to
predict what a 50 deg cylinder temp drop would do to the manifold air
temp.
