Chuck, is the oil cooler air coming from inside the top cowling space over
the heads, or do you have a separate NACA duct for this?
Also, you need to look at the air flow into and through the cooler. The transitions
should be smooth, not abrupt, and open generously. You can ram too much air into
an otherwise fine cooler setup. Jamming eqals turbulence and lower air flow
with far less efficiency over the heat exchanger.
Another consideration. It is OK to have excess power for takeoff, then throttle back and climb slower / fly at reduced power, especially in hotter weather. Many certified craft do this, especially turbo charged engines and turbines.
Or just fly higher in cooler air!
Deep peace of the Light of the World to you.

Subject: Re: Blended foil prop
Although I am having better performance with my new blended foil prop, the
down side is higher oil temperatures. My cylinder head temperatures still
remain below 300 degrees, but my oil temperature has climbed from 190
degrees to close to 220 degrees. It was suggested I install a very expensive
Airwolf or ADC spin on remote oil filter system with claims it will bring my
oil temp down 15 degrees. Another suggested adding another small oil cooler.
But I wondered if that would lower my oil pressure. I don't know if my oil
temperature jumped up because this prop pulls harder or if it spoils the
air flowing into my cowling. Any suggestions?!!
PS: Wentworth Air Salvage quoted me a price for an Airwolf out of a wreck
without hoses and filter for close to what AC Spruce sells a new complete
kit for!!
