Description
The supercharger has proven to be one of the most effective means for obtaining increased power from an internal combustion engine without having to make major engine modifications. This is accomplished by compressing combustion air before it enters the cylinders, which increases density. This results in improved cylinder filling, allowing more air and fuel to be burned in the combustion cycle, with dramatic increases in torque and horsepower. Speedmaster has developed its line of centrifugal superchargers to a performance level that has it regarded as the performance and technological leader in aftermarket supercharging.
