Supercharged engines are engines that have been modified to produce more power than a standard engine. This is usually achieved by adding a turbocharger, which forces more air into the engine, allowing it to burn more fuel and generate more power. Turbos are a type of forced induction system, which uses exhaust gases to spin a turbine wheel, which in turn compresses the air entering the engine. This increases the amount of oxygen available for combustion, resulting in increased power output.
