First off, I'm not quite sure I'm posting this in the correct section, so if this discussion is better suited somewhere else, feel free to move it. Now... I have been reading a lot about divergent/convergent radiator ducts. Sealed airbox for the radiator with a small opening up front, gradually tapering to the size of the radiator, with a sealed exit chute directed to a heat extraction vent in the hood, or the wheel well(s). Not only does this make the radiator more efficient, but it alao plays a significant role in front downforce and drag reduction. The theory of this type of radiator ducting has been proven on the P-51 Mustang plane. It was so effective that it actually made measurable thrust. On a car, that "thrust" would be directed upwards, producing downforce. This is evident in racecars and supercars (think McLaren P1). Obviously, the ductwork would be less than optimal given space restrictions such as factory bumpercover size, radiator support placement, and space between the radiator and engine pulleys. And the vent placement is dependent on hood profile. My question, I suppose, is if anyone on here has invested any time or thought into applying this to the SN95? Blocking off the grill opening and only using the opening in the bumpercover as the inlet for the radiator duct, ducting the exit of the radiator out a vent in the front of the hood, and a belly pan under the engine compartment... that is the basic system in question. Has anyone done this? Pictures? Opinions? Thoughts? Concerns?
