A supercharger is the safer, more cost effective application.Turbo add a lot of heat to your engine and are more prone to problems. They also require a lot more turning.Superchargers are almost plug and play. They require very little to install. Are a lot safer for your engine than turbos. They dont have massive turbines so and run off cooled intake air (as opposed to turbo running off of hot exhaust air) so they keep temperatures in the engine bay down.Superchargers give you more power at lower RPMs.Superchargers generally give more torque gains that Turbos.
