What does a turbocharger do for a car?

A turbocharger gives an engine extra power without sacrificing fuel efficiency. It is typically added to smaller engines to improve performance. Today you can find turbocharged engines on many vehicles, including sports cars, trucks, sedans, and luxury vehicles.

A turbo improves efficiency even on the throttle, even at identical parasitic drag. This isn't just fuel efficiency, but thermal efficiency. A turbocharger gets you closer to an ideal power cycle.

It is possible to add a turbo to any engine that doesn't have one. However, the success of this process depends on careful preparation and following the necessary steps. This includes upgrading the ECU, enhancing the clutch system, overhauling the fuel system, and upgrading the internal engine components.
