What's better, a supercharger or a turbocharger? Well, while they both do a wonderful job of increasing and engine's horsepower, they go about it in quite different ways. The turbocharger relies on exhaust gas pressure to spool up a turbine to deliver more air to the engine. A supercharger on the other hand is driven by an engine belt, which rotates a compressor feeding the engine fresh air. While ultimately both will result in more power, there are advantages to each, such as throttle character
