The words “NACA Duct” usually go by so fast that they sound like “Nackaduck”, but a NACA duct is really just a specialized type of duct. Ducts are hoses or other devices used to move air from one place to another. brings air into (in our case) a racecar in a very special way. Clear NACA ducts can be seen in the rear windows of NASCAR cars – there are usually two or three in the window. Carbon-fiber NACA ducts sit in the front of the car.
One of the commentators after the final race in Homestead mentioned that Jimmie Johnson should be happy he finished in third because it allows him to avoid the “dreaded second-place curse”.
Anytime someone says something like that, it makes me wonder whether there really is a curse, or whether that person had just been talking to Carl Edwards. So I analyzed a little data and guess what… there really IS a second place curse.
