Dave,
Some builders of Van's AC have similar
problems with exhaust systems too close to cowlings. Van's has a metal
(stainless?) tape that you install where needed. Other builders have installed
either gill vents on top of cowl, or a door controlled by cockpit accessible
cable. Also, when Mooney's put turbo's on some of their AC, you had to taxi and
idle for almost 15 min. after high power settings to let the temps come down.

New
problem: melt down after shut down. That turbo has a lot of very
hot mass. I flow enough air through the cowl when running to keep things
cool. Right after shut down the cowl is just luke warm to the
touch. But 5 min after shutting down the turbo side of the cowl is too
hot to touch on the top and I can smell resin. It gets a little
soft to tap on it and it is starting to look a little mottled and maybe
yellow (if I let my immagineation run away). I have seen a couple of RVs
with drop down hatches in the top cowl to let heat out after shut down.
Does anyone have an idea about how hot I can let the fiberglass get?
Bright Ideas?
