Supercharger
A supercharger is a device that mechanics install or repair to make car engines more powerful. It works by pushing more air into the engine, similar to how a fan makes a fire burn hotter. Unlike other power-adding devices like turbochargers, superchargers work instantly because they're directly connected to the engine. Auto repair shops often look for mechanics who can work with superchargers because these systems require special knowledge to install, maintain, and repair. They're commonly found in high-performance cars, muscle cars, and some luxury vehicles.
