Here's a graphic showing the pressure measurements across the top of the hood relative to under:
Measurements were taken at 42 mph and averaged between one N run and one S run at each location; wind was 10 mph NW.
For vent location, the passenger side presents no difficulty; however, the driver side has the inverter at the front of the engine bay and the fuse box along the side behind the headlight, two things I would rather not get wet. A vent in the middle of each side right over that -1.3 reading would miss both of those, perhaps with an additional vent across the front just behind the radiator.
