I moved the oil cooler inboard to the armpit location and closed up the

climb to 4500 feet. Cruised around at 5400 RPM, oil temp 180, coolant

temp

1/4 on the idiot Mazda gauge. 13C morning. I have never seen temps

this low

at this higher power setting. Lesson learned: do not use a 12A oil

cooler on

a 13B, even if it looks the same. Hopefully I can fly around now in the
hotter climates next summer. Attached are some photos.

Notice in the photos also, that I lowered the coolant rad leading

edge, the

air is split about 2/3 to the rad and 1/3 over the engine and finned

oil

pan. The rear of the coolant rad is raised slightly to improve flow

into the

ductfan. After moving the oil cooler inboard and closing the cowl

holes I

gained another 50 RPM on climbout, 5270 now at 90 knot climb. The

ductfan

inlet seems to be very sensitive to obstructions.

   Perry,

     You're out in McMinnville right?  Do you mind if I come out to met
you and see your aircraft?
