Paul, I see you are back, just wanted to let you
know I probably won't be attending Camarillo.
You've seen my plane, I've made so many mods lately
(intake manifold and oil cooling) that the cowl is
still very rough, splotchy and unpainted. I've
decided it just isn't presentable enough to be
judged. If Spencer is there with his V8 he would
win over me in cosmetics and performance.

I used a camping stove to heat some water and
finally tested my oil temp gauge and sensor.
It reads 222F, so it is reading high by 10F.
That means that I can climb out full throttle on
a hot day only to about 2000 feet before temp
hits 210 and it will still go to 220 easily.
Better than the 230 that I thought it was though.
We know the oil cooler is getting good airflow
so maybe it's mixture-related, will check that
soon.

I put on the finned oil pan, was disappointed,
no apparent improvement. Could be there is just
not a lot of airflow in that area, will try to
take some pressure measurements to determine if
there is airflow there. I might be able to put
some ducting in from the NACA to feed it.

I had it build from 1/8 material because that is
what I had laying around but I think 1/16 would
be sufficient, transfer heat better and be lighter.
The fins are 1/16 x 1 on 1/2" spacing inside and out.
