Turbochargers and Superchargers are two forms of forced induction, but use different means to achieve it. There are a number of differences between the two, and they are sometimes better for certain applications.

Power Gain Difference
The amount of power that a Turbocharger or Supercharger has to offer depends entirely on how they are designed, and even the power band shape differences differ, depending on the type, settings, engine, and other factors.
