For all you guys with RV4's and RV3's with cowl cylinder bumps.
 Here is an idea for cowl flaps. This is on a Turner T40 that did well in
 the 350 mile x-country  race from Corona CA to Sacramento CA.
 The hinges are like those on your car trunk lid.

That would have less drag with the sides (a.k.a top and bottom of the flap)
sealed off.
