    Dennis,

    I suspect the center-back of this vent will want to lift up and may tear the thing to pieces. Wind drag is a powerful force than increases exponentially with speed. It may go POOF!

    Just a thought.

    Hello, Roger.

    My cowl vent air scoop prototype is complete (I think) and I will drive the car to work tomorrow morning and see what happens.

    I considered anchoring it along it along the back side, but it looks to me that the wind will push the scoop with a clockwise torque (when viewed from the driver's side). That means that it would push the trailing edge of the scoop down, not lift it up.

    Agreed. I will keep the vent doors and a vent window open to give a clear flow path for the air and minimize stress on the scoop. I will accelerate slowly and watch the scoop for shaking, flapping, or bowing and hope that the quarter-turn anchors do not pull loose. My top speed in tomorrow morning's traffic will probably be around 45 mph and I will keep a screw driver handy in case I need to pull over and take the thing off.

    Flight Report

    I drove the Falcon to work with the windows up and the vents open. The morning temperature was 62° and it forecast to be 82° and mostly cloudy at 5:00. The cowl vent air scoop worked nicely. It channeled more air through the vents and made it breezy the inside of the car with just a vent window tilted open. I turned on the heater and directed air flow though the heater core and it worked fine. I hit a top speed of 55 mph and the top of the scoop shook a little bit. A center support would increase the scoop’s structural rigidity and eliminate the shaking.

    So, the cowl vent air scoop did work:

    Sixty square inches of Ram Air:

    But .... I drove home with all the windows down and the vent widows tilted all the way out to act as air scoops. Under that setting, I could not tell that the vent air scoop was adding much to the general air flow. There was some air blowing against my left leg from the vent, but it was rather insignificant compared to the amount of breeze that was present as a result of all the windows being open. I removed the air scoop when I got home.

    Analysis:
    Once again, I cannot improve on the stock ventilation design that was selected by the Ford engineers of 1959 who designed the Falcon. Those guys really did a good job. The vent system of the early 1950's that Roger referenced used a "ram air" concept.

    The Falcon's design engineers, however, seem to have achieved a better understanding of aerodynamics. If a vent scoop would have worked better, they would have included it. They instead selected "cowl induction" over "ram air" to supply the best ventilation for the Falcon. When air flows over the hood and hits the windshield, it has to slow down while it changes direction. It piles up on the windshield and creates a high pressure bubble that will follow a path of least resistance.

    The Ford design engineers placed the Falcon's ventilation intake grill at exactly where there is a high pressure air supply that will rush down through the open vents. The stock ventilation system of the Falcon is perfect as is. A cowl vent air scoop providing ram air is not needed. Dennis Pierson from 2016 speaking to the Ford engineers of 1959 who designed the Falcon: "I understand what you did and you did a good job!".

    Addendum: On reflection, however, it would have been nice if Ford han made the vent inlet louvers removable so that the cowl drains could be accessed and cleaned if the became blocked.
