what is less damaging
IO550/520 and we need to be at a non-screamingly noisy rpm as soon as possible due to a typically noise sensitive airport.
Which is less hard on the engine - reducing to 25/25 after take off or leaving the throttle where it is and reducing rpm to 2500rpm?
Since reducing the throttle on the Continentals turns off the 'extra rich' switch, the 25/25 may put the pots in as much stress as pulling the rpm back.
Have the APS guys done this - reducing RPM with throttle wide open and seeing what happens, when do things get nasty?
