Curious to see how much if any air from the hot exhaust migrates into the intake. Pink ribbon test held at various distances between the two holes when grills are/aren't attached? It looks like there is room to enlarge the intake hole higher and if there isn't any air migration, to the right. 100 degree intake might indicate some commingling so maybe not the right. Most of your big gains in performance may have already been made.

Another exhaust vent style.
