On my van (2WD) the engine compartment is a high-pressure area when
driving, high enough to lift and move the hatch if it's not
latched.  I'd like to know whether that pressure is generated by the
scoop (seems unlikely to me given its size) or coming from behind or
underneath the vehicle.  Is it known which direction the air normally
flows in the left-hand vent column (the right isn't a vent, it's the
main induction system)?

Yours,
David
