While your driving the majority of the air flow will be out the bottom of the engine compartment, that opening is much bigger, the air will take the path of least resistance.
Yeah, I am not completely sold on the idea yet. The vents would be the highest up and back as far as I could get in the compartment. It would be a true vent on the inside with a scoop much like a NACA Vent, so although smaller in size, the opening would actually be bigger than it appears. You can't tell from the 2D but all would have a rectangular opening behind that allows flow toward the door..the badges would be tapered slightly off the surface of the panel. The heated air will want to rise and the gaps at the firewall are the path of least resistance now, so I will take care of those first. Hitting the firewall is what is forcing the air downward. I am seeing the affects of this now as any time I speed up the heated air then rushes in, drop back to a steady speed, not so much air coming in.

Thanks
