I went flying yesterday and have some numbers to report. The extra baffling in my above post knocked about 30 degrees off of my max temp. I ran the motor really hard, a lot of race circuit WOT and extended flat spins at WOT. I have the sensor at the back of the cylinder which reads about 30 degrees higher from the front according to my readings. My next attempt will be to make more air flow through the back cylinder fins and not escape around them.
Silversurfer-wait to you see what baffling I have planned for the Suk
Happy New Year.

Here is a quick attempt at improving the minimal baffling I had. It will "some what" form a seal on the top and sides of the cowl. This little extra baffling that I am adding only took me a few minutes of actual time.
I will report back on temperature differences once I get a chance to take some. The temp gauge I am using it the one Geistware used in his experiments.
