Which Is Better: The Turbocharger Or Supercharger?

Which Is Better: The Turbocharger Or Supercharger?

To provide an affordable boost to horsepower, there are really only two options. While the two operate under different principles, in the end they do the same thing; they provide additional power to get you moving faster. 

A turbocharger uses the vehicle's exhaust to spool up a turbine which in turn powers a compressor. The compressor then forces more air into the engine, increasing the compression ratio. This equals more horsepower and a big boost in speed. A supercharger does the same thing essentially, but uses gear or belt driven mechanical components in the process for power. Both have advantages and disadvantages.

Since a supercharger doesn't rely on the spool up from exhaust gasses, the power you get is immediate. A turbocharger experiences some lag, but is more efficient. It's only using wasted energy from the force of the exhaust gas and turning into useful energy.

Turbochargers normally provide a larger horsepower boost, but they also require more attention. They need more lubrication than superchargers and they create more heat. Turbochargers are also frequently the reason for engine knock, as the combustion from the added compression becomes slightly unstable. 

In the end it's really a matter of choice. Superchargers are more stable and adjustable, but turbochargers provide a larger boost on average and are more fuel efficient. It all comes down to which would you prefer: control or power?
