Reply to "Functional air intake on c pillar?"

With all due respect to everyone here, my interpretation of what was meant by positive and negative air flow from the rear window location that has been opened to the atmosphere, i.e., the glass removed is that within that 3-4" boundary immediately surrounding the cars surface, with the car in motion, the air flow will be out of the engine compartment, not into.

That is defined as negative air flow.

Beyond that static air boundary, i.e., further then the 3 to 4 inches to the surface, a scoop will create an air flow into the engine compartment.

If one completely isolates the induction to some kind of a ducting device (hose) and attaches it to the scoop, if it is within the 3 to 4" boundary of the cars surface, the air flow will be outward, away from the engines induction. If it is beyond that boundary, it will be into the induction.

Obviously the engine will continue to provide a demand for air in a completely enclosed system and at some point in the engine rpm and the vehicle speed it could reach a point where no air will flow into the induction.

That is presuming that the vehicle speed necessary to create this static situation of no flow in or out, is within the useful speed of the vehicle.

In other words, not at something over 200mph for example?

I think the best solution is to use a scoop that is not connected with ducting to the induction and therefore permit the direction of the airflow change or adjust itself as the aerodynamics change the direction of the air flow.

In that case the scoops become indirect sources of increased air induction and are engine compartment temperature lowering devices under most driving conditions, i.e., all but flat out racing conditions.

In my case I am not Walter Mitty. It is very unlikely that I will run ever flat out at LeMans in any vehicle, including my Pantera. Some other Pantera owners may feel otherwise though?
