Carburetor scoops do they make a difference?

Shane, it will add HP with only allowing cool air into the engine. A scoop on the carb should be good as well. Use with a filter unless it is "designed" (Key word there my friend!) for use without a filter. Sealing the carb to the hood like Cudaspaz and 805moparkid did is the best and correct way to do so. (I also lovethe extra step 805kid did with the hood cut up for heat relief. (Though extreme for some of us street drivers.) Anytime you force the engine to breath fresh air, it add's power. Anytime you force the carb to breath in cooler air than under the hood hot air, it add's power. Having a scoop on the carb or hood and/or sealing the fresh air coming into the carb ensures max power output over hot underhood air.

These devices have been proven years ago on the race track.

As far as the above claim that it is just turbulent air, I can not say. Perhaps there using it wrong? I don't know.
