Scott,

I'll take a closer look.

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?
