Whatever the gear well covers do I don’t know.
I have 9.5” steady H2O ram pressure in front of the middle of the scoop,
5/8” below the underwing surface; and that’s plenty adequate.

Oil cooler inlet
I'm in agreement with TJ on this
one. Tuft test is definitely in order. I did not realize that the gear door and
wheel fairing were where they are. Even if the transition is fairly smooth, the
opening at the wheel and the gaps in the door are going to make a mess in the
area aft of the door. Think little jets of air from all the gaps. This will
trip the boundary layer and make it much thicker than normal. It would
have to be fully sealed (air tight) around the gear door to stop this.
Any high pressure that the open
wheel well develops will squirt out around the door.
I would test to see how bad the flow
is loused up around the gear door with some oil or tufts. You may find that
sealing the fairing up improves things a lot.
Sealing the gap around the cooler
certainly can't hurt things.
Interested to see how the VG's and
gap seal improve things.
