The rear edge of a bonnet is a high pressure area whilst moving, so rather than venting air out there, it will actually be pushed into the engine bay.
|
Are you sure about this??
The windscreen will see a high pressure due to the dynamic pressure acting normal to the screen, but I am not so sure that the bonnet will be.

i'm fairly sure this is true. remember that a lot of the air originally in front of the car has gone up and over the bonnet already. if you had a splitter, this would be even more pronounced...
while the air at the bonnet/windscreen might be lower pressure than the radiator air intake point, it will certainly be higher than underneath the car, so you will introduce air into the engine bay...
remember the walkinshaw commonwhores? rear facing air intake? they didn't do this to decrease the intake air pressure 
i also vaguely remember tests that someone did, (maybe J.Edgar) but i can't remember...
all you need to test is to put one end of a crude manometer vertical tube with liquid in it) to the gap at the bonnet, and compare to under car and in front of car.. be careful with the direction of the tube opening as that will affect the pressure readings..

EDIT: and you would be better off having a lower front apron/spliter that directed air around and over the car, to reduce the below engine presure and suck more air thru the radiator and from the rest of the engine bay.
