I did search but found nothing.

How do you measure air pressure around a moving car? I have 2 reasons for wanting to do this

*To work out where to put an engine air intake (I want high pressure when the car is moving at 50 - 100kmh)

*To make an underbody tray - aero device to smooth air flow but also to work out how / where to place vents in a low pressure spot under the car to draw air through the radiator grill and out of the engine bay. I live in inland NSW Australia and it is often at 35C in summer, so although I have reduced the size of my grille (partially blocked) I still want to know there is good airflow once I make an underbody tray.

Thanks - any ideas appreciated
