Anyone make the hoodscoop functional?

It IS in fact, a negative pressure area. I have checked this numerous times, and had friends do the same. The most simple way to tell, is to spray water on the hood, and see how fast you have to go before it blows off. I could get to 40 mph, and the water drops would just sit there and quivver. In this pic, you can see how air flows over a truck:



In this pic of a Dodge RAM, arguably one of the more areodynamic pick ups, you can see that high pressure is dictated by the darker colors, while low pressure is described by the lighter colors. You can once again see the hood area, all of it, resides in a low pressure area.

 

In this pic useing Smoke as the visual aid, you can see the smoke doesnt come into contact of the hood at all. Only hitting the truck at the windshield, and roof line.

 

Sure. Putting it in the stream of high pressure air would allow the scoop to be functional, at the cost of decreased forward visability.

 

You can "want" physics to not work all you want, and ask who ever you want, until you get the answer you like......Its doent mean the result will be different. And its "Bernoulli"

 

The hood scoop is less than 2" tall. Now....by your logic, being as the scoop is closed off, dont you think it would creat drag in its location, if it was in the airstream? Now....Comparing the hood on a Pick up, to the wing of an aircraft, is silly. DOnt you think?

 

First, calling me a lier is gonna piss me off. Now, as for the hood issue, all Im doing is telling you how it is, as many people on here have already done. You can argue all you want, but its not going to change how the air works on your truck.

 

Im not sure how else to help understand it, than whats already been posted. To help wrap your head around it, spray some water on your hood, and drive in a straight line. See how fast you have to go to get it to blow off. Also, Look at the design of vehicles that have actual functioning hood scoops. The WRX for example, has a lanted nose (more so than the Tacoma), and the scoop sits up quite a bit. Not only that, the a scoop in the center of the hood, even "if" in the air stream, is a horrible location for one. The Crysler "Air Induction" of the later 60's and on, was a good idea. The scoop faced backwards, and was at the base of the windshield. This is because the air over the hood, was found to "swirl" in a clockwise direction, and the base of the windshield was were the air (high pressure) came back into contact with the vehicle. My Honda has a factory air intake scoop on it. Its mounted at the top of the radiator, and gets its air right from the grill at the fron of the car. Just as in the pics I posted, that is a nice high pressure area.
