Not at all. There is a mountain of engineering data concluding that
reducing RPM reduces fuel flow and cooling. In fact, I just spoke with
one of the test pilot the other day who talked about flying the
instrumention for that. Its too bad Cessna doesn't do the same level
of
engineering.

This is not making sense, to me. Of course increasing fuel flow by
richening the mixture results in cooler CHT's, but how does increasing
fuel flow by increasing RPM give cooler CHT's? My engine runs hotter at
higher RPM.
