While we're thinking cowl cooling issues. My factory diagrams had a sketch of a door closing off the 5" x 8" hole at the lower cowl trailing edge (nosewheel slot).I suspect it was a 200 early artists conception which never got into design. Although I've not heard of anyone doing this (probably due to the mechanical risks) it's something I've looked at for a long time. It would seem to me that there is a vertical gusher of exit air here all pointed the wrong way. If CHT's could handle it this might be an area of improved cowl exhaust giving well in excess of 1/4 kt. Thoughts? Larry
