turbo or supercharger
So my windshield intake feeding the engine directly is a supercharger too?
Nah, it acts more like a turbo, low pressure below 20MPH, up to 7" positive pressure at 70MPH and the engine will never accept more air this way than it can use, unlike a supercharger that can blow out the top and bottom end of an engine.
BTW, you can put an electric motor on the end of a supercharge as use it for a high volume air compressor, with the right base.

From Answers.com
" An air pump or blower in the intake system of an internal combustion engine. Its purpose is to increase the air-charge weight and therefore the power output from an engine of a given size. In an aircraft engine, the supercharger counteracts the power loss that results from the decrease of atmospheric pressure with increase of altitude. Various types of pumps and compressors may be used as superchargers, which are either mechanically driven by the engine crankshaft or powered by the engine exhaust gas. See also Compressor; Pump; Turbocharger.
Some production automobile engines use a spiral-type supercharger, while others use a pressure-wave supercharger. However, automotive, marine, and stationary engines generally use a positive-displacement Roots blower driven from the engine crankshaft. See also Internal combustion engine.
In a supercharged diesel engine, the increased air charge allows the engine to burn more fuel and produce greater power without creating excessive pressure inside the cylinder. Supercharging the diesel engine makes ignition of the fuel easier without requiring a fuel of better quality. See also Diesel engine.
To enable a reciprocating aircraft engine to develop its rated sea-level power at altitude, a supercharger must be used to increase the pressure and weight of the intake air charge. Centrifugal compressors are generally used because of their relatively small size for a given capacity, and are driven either by a gear drive from the crankshaft or by the engine exhaust gas. With gear drive, a lower ratio is commonly used at low and medium altitudes, with a change to a higher ratio at high altitudes. See also Aircraft engine."
As you can see.....or maybe not for you, all the definition of supercharging requires is that...and I quote....."to increase the air-charge weight and therefore the power output from an engine of a given size." Notice that is does not specify HOW it is done. A turbocharger has been and will always be a form of a supercharger. It has an impeller on one end for driving and a fan on the other for discharge into the engine. It does the same thing as a roots type blower, but in a different way. An engine is said to have a super charge of air and fuel as long as it has a positive pressure on the induction system. It is indeed that simple.
everyone needs to stop watching tv shows where they call blowers superchargers and say a turbo is something different. supercharging is a way of forced induction whether its wasted energy (exhaust across a turbine) or a direct mounted belt drive blower. and settle on a ripp like everyone has mentioned.
[QUOTE=RedneckJeep;1068760]No, because your windshield intake is not capable of producing boost. Here, maybe this will help.
Gee that's odd, since I can put a magnahelic on my dash with the + hose connected to the intake (air filter compartment) and get anywhere from - 0.6 to + 7.6" W.C. and that my friend is pure pressure, obviously more air than the engine is currently using at any particular time. Obviously the negative pressure is at the lower speeds, like less than 20 typically.

My first thought was that they were different (supercharger and a turbo) but after looking at the following site (en.wikipedia.org/wiki/Supercharger) they say "A turbine-driven supercharger is known as a turbosupercharger or turbocharger". I guess peoples impression is that a turbo is different, but it is a type of superchager...

For looks I liked the old sidedraft paxtons. Especially when cradled between the finned aluminum heads of a V60 flathead.
Then what is the difference between a turbocharger and forced air via the windshield vent? (Other than the obvious physical difference)
The turbo is capable of putting the induction system under pressure, the air vent is not. Are you really this thick, or are you yankin my chain?
