ill b doing the gotts and a k&n filter, this thread made me curious abt lightnings though, i wonder if they have the same stock opening at the fender well, for the supercharger on these 5.4s

That is a good question. I know that some of the aftermarket S/Cs use a CAI style filter at the end of the intake pipe but I've never looked under the hood of a stock S/C F150. As long as you leave the intake sensors and their surrounding housings alone, you can do whatever you want to the intake.

One thing I read is that when the vehicle is travelling, the body creates an airfoil around it and that the pressurized airflow is actually about 2-3 inches above the hoodline. This means that your hood scoop would need to be at least 3 inches or higher to have ANY effect. Otherwise, you are actually operating in a vacuum.

Fun stuff, ain't it?

Even if they are considered ineffective I still wouldn't mind having one.

The pitot tube opening, that picks up ram air pressure for aircraft speed is positioned quite a bit away from any part of the fuselage or wing for that very reason.

Much of what we'd "guess" in aerodynamics is just plain wrong!
