I would have to climb at 125 kts to keep them cool which gave me a climb of 300fpm. I copied an idea someone had on the forums. The cowl flaps fit tight under the muffler and fold when closed. This allows for fences to be present on both sides of the cowl flap. My RV10 now can climb at 110 and show 1000fpm in the climb and the CHTs run around 350-380. I live in Oklahoma and they have been a big help in the climb performance. I have their details and drawings on my web site http://www.nwacaptain.com/cowl_flap.html. Just another idea for you.

Your page certainly validates cowl flaps as a way to fix high CHTs. While others have added shark's gills and other louver varieties, I always figured they would add drag in cruise and not give you the control of cylinder temps that cowl flaps do. I remember the summer I spent in OKC where 90 seemed the equivalent of 100 anywhere else. Where frozen goods would melt between the store and the car. Not my favorite spot to reside.
