Hi all,
Well I flew N727MM for the first time Saturday, and I was delighted/discouraged.
Delighted in the fact the airplane handled almost perfectly with just the slightest hint of a right wing heavy condition.
Discouraged in that I couldn't fly very long due to high CHT's. I mean like 440 for a short time. Oil temps weren't overly high.
I have an overhauled O-360, 9:1 pistons, Sam James cowl/plenum.
I understand there have been some issues with SJ cowl, so my question is, what have some of you done to mitigate the high temps, other than fly fast?
Can larger inlet rings be fitted to the cowl without major surgery? BTW, I have a new SJ cowl that I will be doing the surgery on.
