Greetings,
Well, I had everything
back like it was previously, so I figured I would just go up to make sure my oil
temp was back to 180 like before. Instead, I found
that the temp climbed to 220 by the time I got to 5000 ft.
This baffled me,
until I realized (hours later on the way home) that I had only briefly
tested the temps after blocking off the bottom opening in my cowl. Looking
back on the logs, I did that test when I was limited to a couple thousand
feet, for a short flight. Bottom line is that it wasn't a good
test.
What made me
think about this, was the fact that I "thought" I caused the high oil temps
yesterday, when I reduced the inlet from 80 to 48 sq inches. In fact,
today's numbers are almost identical, so the inlet restriction didn't really
hurt me much. Once I realized that the inlet change didn't hurt me, I had
to assume that the outlet was too small, and then I realized the error
of my testing methods.
For the next flights, I'll
remove the cover plate on the bottom exit, and make sure I'm back to 180
for oil temp. If that's the case, I'll just have to factor this into the
Rev 2 plan, and I can go back to restricting the inlet.

slowly)
