OK how exactly does a superchrager make an engire more powerful? It's basically a high volume (high flow) compressor that produces positive pressure in the intake manifold. But does the extra power come from the fact that when the intake valves open air rushes in "under its own power" as opposed to having to be "pulled" in (thus robbing power)? In other words, a superchrager is really only making the intake stroke *less* of an energy hog that it would *normally* be, correct? So even with the best supercharger in the world, you're only going to get so much of a power boost because you can in theory only make the intake stroke rob zero power. And, if you are stupid and put smaller pulleys and such on you're not really doing much except second guessing the design engineers who made the 'charger, because there's only so much air you can cram into the cylinders. Is all of this correct of am I missing something?
