Assuming that the print below in bold is true, does anyone know if the operation of a GMT400 throttle body is similar enough to that of a carburetor that the added pressure created by increased air hood scoop create problems?
Functional hood scoops are situated in a high-pressure area of the hood. At higher rates of speed, more air will enter the hood scoop, and it will be moving at a higher velocity as it does. This cooler, denser air is responsible for the performance boost associated with hood scoops. In order to “catch” this air, the hood scoop needs to have an opening that’s high enough to clear the boundary layer around your car.
Engines rely on fuel and air to propel your car. Fuel is easy to increase, but it’s harder to increase the air intake or to get more power from each combustion. Hood scoops are an easy way to increase the air intake and also to ensure that the air being used is a desirable temperature or pressure for optimal combustion. In short, hood scoops function much the same way as cold air intakes, but they can be combined with cold air intakes for even greater power gains.
installing a hood scoop can be a serious problem for your engine. If you have a carburetor, then a Ram Air hood scoop could cause serious harm to the inner workings of your car if you don’t take the proper precautions.
