Just my 2 cents. This will be a significant restriction, with air moving over it at over 100 mph. I see a possible flow issue. I would taper each side to a V.
Also, if it is possible to integrate the mount, such that no cross sectional area is lost at that location (larger diameter chamber that flairs back to normal) that might mitigate head loss.
