Giving us a bad name here... ugh.

off topic but kinda funny , is it a Civic or Mustang?

Maybe he just likes the horse. Can't knock him for that =)

Yep.

So is this guy on the forums? First of all downforce is created to make the car stick like glue during high speed cornering... Why does he still have prius tires on? Secondly WTF was he thinking with the installation?

I would also like to know if he is. On a more serious note, someone should tell him. At highway speed any small amount of lift could make the car more dangerous.

Maybe I am wrong, but wouldn't the wing need to be upside down to create lift?

Sure it is on backwards, but wouldn't it still create downforce? Just not as effectively?

I am no physicist, but I don't think flipping a wing backwards changes the direction of the lift. I would think that flipping it upside down would do that.

Growing up in an aerospace household and after building countless flying model planes from scratch, I know a considerable amount about airfoils but I don't consider myself an "authority" on the subject. I work with aerospace engineers on a regular basis and I wouldn't dream of insulting their experience and education by labeling myself such.

The problem with what the guy has done here is that the design of that wing utilizes a basic airfoil (thicker at the leading edge and tapered to the trailing edge, similar to an airplane wing. To generate lift, the top of the airfoil is usually curved at a higher rate toward the leading edge and straightening out as it moves aft while the bottom is usually flat or concave. As air moves over the airfoil, it creates an area of low-pressure on top of the and an area of high-pressure below. This results in "lift".

Now on car-wings, this airfoil is inverted with the flat or concave surface on the top and the curved area on the bottom. This is how reverse-lift or "down force" is generated. The amount of "down-force" can be adjusted by altering the angle of the wing in relation to the air-flow. This is known as the "angle of attack". While down force can be increased in this manner (by tilting the front of the wing down), it also increases drag.

What this IDIOT has done by reversing the wing is render the airfoil backwards. This completely negates the aerodynamic properties of the design and increases drag. If you notice the little "lip" on the trailing edge of the wing, it is disturbing the airflow over the top of it to create an extremely turbulent, low-pressure area above the wing. So unless he were to compensate by tilting it dramatically, his wing is generating considerable drag while generating a little lift.

the wing probably works THAT well

This makes perfect sense to me
