Specifically what he is seeing is that cylinder #2 CHT is about 436 degrees peak, during cruise it is running 400-420 degrees. The next hottest cylinder is number 4 which peak is 392 and cruise is 340-360 degrees. Cylinder #1 and #3 both peak around 390 and cruise at 305-320 degrees. Is this normal for this engine or should he worry about it? I have all the data in an Excel file sampled at about 10 times a second, so if anyone wants further detail send me a private email and I can send you a copy of the data. Thanks Trampas
