Here's the thing that makes it confusing. If you look only at
cooling results, Paul was right. I could have gotten equal or
better cooling improvement by using a cowl flap. BUT, this
improvement comes at the expense of added drag, especially at cruise
& top speed (racing). By improving the pressure recovery instead, I
got the improved cooling with almost no increase in cooling drag. This is the ultimate goal in aircraft cooling design.

How can you tell, Tracy? That is to say, is opening up the intake producing more drag than a cowl flap would? How do you measure the effects of both so that your not just guessing?
