Today was a hot, but not blistering hot day in St. Louis (about 88 degrees & humid). I tried out some of the lean on climb input, and here’s what I came up with.
When I leaned (2000’ agl, 2500 RPM, 50 lean of peak which was 1390 CHT) the oil temp and CHT stopped climbing, but didn’t go down - stayed at 210 and 430 respectively, climbing to 8000’. Still seems troublingly high.
I also noted, in cruise, the differences by cylinder. CHT’s were: 360, 350, 330, 320, 350, 340. EGT’s were 1410, 1390, 1350, 1390, 1380, and 1420. These seem like pretty wide ranges - is this normal, and could it be related to my high temps? And are my temps high? Is GAMI the answer?
