Abstract

A vehicle intake supercharger is described herein. The supercharger is driven by a continuously variable transmission (CVT), which is driven by a main car transmission through a transmission output shaft. The present invention significantly improves boost by the supercharger at mid and high-end revolutions per minute (RPMs) and reduces boost lag at low-end RPMs with lower power withdrawn from the engine at higher gears. As the transmission output gets faster, lower engine power is required to spin the supercharger, where boost is optimized by the CVT depending on many factors, such as driving conditions, driver input, engine RPM and max engine intake pressure.
