I installed a 4 inch flex tube to bring air from the left nostril over to the radiator and that solved the problem!  Water temps climb to around 208-9 or so on take off and then they lower to the mid 190s.  Oil is running about 175.  Now that I can fly without the fear that I am going to lose the temps, I can concentrate on the checks I need to do during the 40 hour flyoff!  Oat was bout 88 degrees.

I am flying off a Class C airport, so temps are always high before I take the active.
