Hail - if you use a trapdoor into the airbox from the shroud opening, do you think that using the hot air passing through the radiator for intake might cost you some horsepower as opposed to drawing cooler air from somewhere else?

Also, not too sure about the pressure there, as the design by nature is intended to create a low-pressure zone above and in the hood opening to assist in drawing air through the radiator and evacuating up and over the bonnet.
