In North America an exhaust driven intake charge pressure increaser is called a Turbocharger. A belt driven intake pressure charge increaser is called a Supercharger. If I have a battery charger that will give you a blast of higher amps momentarily to jump start the car ,It COULD be called a supercharger ,but it is not. We use the two terms to eliminate confusion but if there is any recognition of the two systems then it is understood to be a device that increases the pressure in the intake tract. T.C.
