I'm trying to diagnose the cause of problem that on my home build VK-30 with 914 F2 engine variable speed propeller
1. Airbox temp goes up to 92 C to 95 C and all other parameters are NORMAL, like oil temp, CHT, EGT etc.
RPM was 5000 ~ 5500 with no drop or any vibration issue gain height 12000 feet to 16000 feet.
as per book, Airbox intervene at 88C. but here no such action was found. why?
