BB Hood/Cold Air
I think everyone was tired of the last thread I posted this, so I'll try again...
Thinking about cold air on a BB hood, if one cut intake holes in the front of the "dips" where they'd be out of sight, then made a big chamber in the inside of the hood to funnel the outside air to the cleaner, could a BB hood be setup for cold air similarily to the pic below, or would the shape of the hood create negative pressure (suction) and cause a problem at speed?
I realize that it's advantageous to obtain cold air from near the base of the windshield where the highest pressure is, but am skeptical that the pressure changes would be enough to make much difference. I already read skepticism about the effectiveness of the added pressure from intaking at the back of the hood...

I think your second statement would be right, the negative pressure would try to suck the air out. I have thought of opening the same point up, but to suck the hot air out from under the hood, and help cooling.

If you look at the C5R, the new Shelby Coupe, etc. they have rear facing holes in the hood - to promote air flow through the radiator and out of the engine compartment.
