So would it be correct to say that since we are flying
experimental airplanes and if the oil cooler from the
"G" is interchangeable with the "N", that this would
be a solution?

My brothers Cirrus has the "N" and has no oil temp.
problems and I know some Legacy owners with tighter
cowls, smaller air inlets than the ES that have no
cooling problems.  How would you explain this?
