Easily as hot after shutdown. I have an air temp probe up near the oil filter right now.

If the goal is more mass flow at approach speed and slower, and given the new door closes from the inside, can you actuate pneumatically? A spring holds it open, and increased dynamic pressure closes it?

Spitballing outside the box, how about pneumatically using manifold pressure? A spring holds the door shut. Low MP pulls it open.
