In the process of testing out my engine monitor (the one I'm building) I ran a detailed log of a flight which captured some interesting facts. Turns out that there's a significant difference in both EGT and CHT between the two forward cylinder and the two aft. Engine is an IO-320 160 HP.
Max EGT Values: 1042.52, 1106.60, 1408.28, 1403.06
Max CHT Values: 322.70, 358.52, 386.42, 379.22
I fully expected the cylinder head variance due to basic airflow, but I'm quite surprised to see that the max exhaust gas temps vary that much.
Note that those are the maximum temp values over the course of a 45 minute flight, sampling at 10 Hz. The averages show much the same:
Avg EGT Values: 870.57, 946.65, 1174.19, 1187.25
Avg CHT Values: 288.47, 317.31, 335.30, 337.83
Does that seem normal, or is there something odd going on here?
