Hi Ron
Do you have an intercooler installed on your 914?
No I dont as I rarely use the Turbo boost except at short or high fields
I probably wont bother, (Extra weight when Im already nose heavy)
I would imagine worst case for potential ice would be fine pitch or at least
Having the wind turn the prop with little to no throttle opening?
Is that what you find?
Actually the CHTs and EGTs drop faster when I close the throttle than the Inlet
temp, The body of the turbo would take longer to cool down so still keeps the
passing air warm, I will make a note to check this when I am next flying
I would also imagine the second you begin to increase MP close to ambient
pressure having the prop pull the aero plane, the heating from turbo compressing
air would raise temp above carb ice range.
When I have used the Turbo then Full power for a sustained climb its always the
water temps that makes me flatten the climb not the inlet temp,
The thing I noticed is the inlet temp increased with height even though the OAT
dropped at a constant throttle setting, I assume due to the lower density of
the air passing the hot turbo, Normal cruise 4800 at 28/29 MAP for me
