N492CM flew for the first time Sunday morning.  It was a short flight (.2)—just enough time for one pattern.

The engine was super smooth, and seemed to have lots of power, although I never really did look much at the dynamic RPM that I reached.  I was busy paying attention to the coolant temperature.  The oil temp stayed below 200 the entire flight.  But I took off with water temp at 185, then with full power and the climb to only 2000, the temp rose to about 230.  I pulled the power back, and basically glided around the pattern for a full stop.  As soon as I pulled the power and dropped the nose, the temp started back down.  When I landed, it was back to 195.  Taxied back uneventful.

I have the small (facial area) thick radiator from Ed Klepeis (see the pic below).  Is anyone else using this one?  How have your temps been?  I would like info and pictures on your setup to see if there is some tweaking I can do to mine.
