"In Brent's defense the combustion chamber of an Ineternal Combustion engine ALWAYS has a vacume on an intake stroke. A supercharger just helps rush more air in during the intake (reducing the vacume and cramming more air into the cylinder)."
How can there ALWAYS be vacuum on the intake stroke, when a supercharger compresses the incoming air stream? When the cams lift the valves, the pressurized air is forced into the cylinder (by positive pressure). It is not drawn in by vacuum. When the charger is not producing boost, the pressure is diverted via the bypass valve and, vacuum of the intake stroke draws in air. (Idle, cruise, light throttle, etc)
Logical?
