James, I'm sure more than a few 440 Sixpack Dodge, Plymouth, and Olds W-30 owners would argue that "fact" with you, but I agree with ya.
When it comes to cold air induction systems, there's a whole lot more "sucking" than "ramming" going on. (hope that makes it past the censors)
.
That's the biggest reason I never made my scooped hood functional.
But if I had a SRT, I would probably open up the vents in the scoop for under hood cooling. Still, it probably wouldn't help that much because the scoop doesn't protrude high enough to get beyond the layer of "dead air" that envelops the car.
Pat, I think the biggest improvement offered by NeedWings intake is better (smoother) air flow characteristics, and volume. Needless to say, it sure works.
As for under hood filters, like Tony (Acrispy1) has, sucking heated air, I don't think it probably makes that much difference on a NA car. After all, that's the way it was always done before functional hood scoops starting showing up on Muscle cars back in the 60's. (Not to mention the 50's Baby Birds)
My 69 AMX came that way from the factory. But when I installed a functional 1970 AMX hood scoop (that had a "foam sealed" housing directing the cool outside air directly into the carb) it didn't lower my 1/4 mile ET's at all. But "obviously" I sure liked the way it looked.
