Hi Bernie,
How did you flight go today regarding cooling. Hope
the work you put into the duct is paying off for you.

Well the diffuser was in place, but barely. We had a
mismatch where it mates with the ring on the cowl, so I duct taped it best I
could and went flying. The ambient T/O temp was 85 degrees, so a bit warmer than
the 81 degrees I previously tested in.
Climbed to 7500 feet in 10 min at 105 knots IAS and the
max coolant temp was 216 and was coming down at the end of the climb. My limit
is really the coolant pressure which climbed to 21 psig before starting down.
Oil temp got up to 190 degrees which is as high as I've seen so this
indicates the conditions were more extreme than before.
Bottom line is that with work to get it smoothed, it might
be a viable system. I am convinced that my exhaust is radiating a good load on
the radiator also. Will add some more length to my s.s. shields that hide the
exhaust from the radiator.
Bernie, hit 40 hours today so can sign myself into phase
