Hi all, no responces on my cabin heat post yet, so I'll try another angle. It's info I want either way besides. Mainly for the guys who fly behind a 912 in the cooler north country in the winter, what are your average cht and oil temps on a winter flight. For instance, if it's 20 degrees F outside, what will your temps be. Also, do you have a round cowl, or a smooth one, and does that make much of a difference in temps? Thanks, JImChuk
