Andrew, In both engines I simply had to install a thermostat to
save bothering trying all the alternatives. tried exit flaps,
inlet restrictions, modified inlets etc. All time consuming and
costly. Many decry the thermostat option but is far simpler and
works. Current rads, Oil single pass 455 x 190 x 55mm thick, or
18 in x 7.5 in x 2.2 inch. Water 515 x 360 x 55 mm and double
pass! 20 x 14.5 x 2.2 inches, New cowl a great improvement on
the old (growth!) Attached Regards, Neil.

Tom, plan is to eventually do that to control temp by
controlling airflow. We have an insidious system here with
experimental whereby our phase 1 has to be completed within
12 months, with any uncertified powerplant its 40hrs. Seems
to be an anti safety system where we are told to just fly
the hours off then fix any problems after phase 1 is
completed. So if the plane fly's too cool I'll put up with
that for awhile. Just about to apply for the second CoA for
this plane. hopefully I don't need 3 or 4.
Lynn, just changed to synthetic, I had thought foaming was
part of the problem, hopefully this does help.
Neil, from memory your Sportsman has been good with temps since
the beginning, seems your temps are spot on. my oil is still
slightly hotter than coolant but no flight yet in this config.
must say its much better to be at this end of the spectrum than
the other. Before, I had thought I just needed more air through
the heat exchangers for it to cool, which I could only get in
flight. big mistake. going to be lots more ground testing this
time.
