A
Ford truck hood scoop is a functional way to give your pickup a unique
look. Hood scoops allow more cool, dense air to enter the engine compartment
than standard intake systems. Keeping the engine cooler will add noticeable
power. At high speeds a well designed scoop will act as a supercharger
and may add up to 20 horsepower.
In order to function properly, a Ford truck hood scoop must be mounted
in a high-pressure area. For this reason, many scoops are located toward
the rear of the hood. In this region, also known as the cowl, the curvature
of the windshield creates a high-pressure zone. A reversed scoop, where
the opening faces the windshield, may also be placed in this spot.
For optimum efficacy, a Ford truck hood scoop must be high enough to
clear the hoods boundary layer. A boundary layer is a slow-moving layer
of air which clings to the surface of any moving object. A NACA duct
is another type of intake which is mounted below the surface of the
hood. This style of intake is designed to draw boundary layer air inward.
