CAMARO6 - View Single Post - Gas mileage after air dam removal (and wind noise fix)

Yea I was surprised, I never expected to get a decrease in wind noise from taking OFF the air dams. But if you think about the air flow it kind of makes sense, the dams force air away from under the car out to the side, where it has to compete with a very fast moving mass of air already whipping by the side of the car. It is conceivable that this introduces oscillation in air pressure around the side of the car, and thats exactly where I was getting my excessive wind noise from.

You can interpret the MPG however you want, but IMO there is no difference at lower speeds, and maybe a slight difference above 70mph.
