Living in AZ, I have worked hard to get good cooling in my -8. Clean airflow, good baffling, running LOP, etc. Now that I am traveling more, I find the opposite problem. At altitude (10.5K ?2K) in cooler winter temps, I find that my CHTs are getting too low , like <280? in cruise, and even less in the descents.
I can keep the oil temps OK by blocking air flow to the cooler, but with my rear-baffle-mounted oil cooler, that makes the CHTs even lower, since that flow now goes through the engine.
Of course, running ROP does make the engine somewhat warmer, but costs me 2 gal/hour for a 10 knot delta, and reduces range. That's what I'm doing for now, but I am wondering if others, especially those that live in colder climes, have similar problems and if they have developed any solutions?
Thanks,
Andy
