Superchargers do not suffer lag – a term used to describe how much time passes between the driver depressing the gas pedal and the engine s response. Turbochargers suffer from lag because it takes a few moments before the exhaust gases reach a velocity sufficient to drive the turbine. Superchargers have no lag time because they are driven directly by the crankshaft. Certain superchargers are more efficient at lower RPM, while others are more efficient at higher RPM. Roots and twi
