Five flights into this Phase I exercise. Engine (Lycoming IO-320) is running great. I've been downloading the data logs from the Dynon Skyview after every flight and pouring over the graphs over on savvyanalysis.com.
It looks like cylinders #1 and #2 are consistently the hottest over the aft cylinders #3 and #4 by about 25 degrees. Cylinder #2 being usually the hottest by a few degrees and #3 being the coolest.
I have the stock air dams from Van's baffle kit in place on the front cylinders and I'm wondering what the concensus is here on how much to trim them down so I can balance the CHT's a little bit closer. Any suggestions on a starting amount to trim off? 1/4" or less?
Should I keep the relative shape of the stock air dams or just start trimming from the top edge downward?
Overall cooling has been just fine, and the past couple of flights have been in rather hot weather.
