Ed, Mark,
I have a cowl flap.
At first it seemed to do no good at all, but after about 5 hrs of flying around
on a 90deg day testing it open and closed, it does seem to make about a 10-15
deg F difference (coolant) and cost me about 5 kts in cruise speed.
It takes a long time for the change to manifest itself in my temperatures.
Luckily I only seem to need it in climb even on a hot day. Looking back,
it was worth the trouble.

Mark,
I
considered them in my early days when I was fighting high temps. But,
once I solved that I have not really considered them. The only person I
am aware of using them is Bill Eslick. You should contact him for
details, but my impression was that while they appear to work in aiding
cooling, they also acted like a speed brake dropping over 10MPH from his
cruise. I believe he also found it very difficult to close them down against
the air flow out of the cowl when he tried to close them to minimize
drag.
But,
again contact Bill for the full skinny.

Ed,
What are your thoughts on cowl flaps. Do you use them?
