Which is Better: Supercharger or Turbocharger?

[OSophie]

Both supercharging methods have their own advantages and disadvantages. Here are the differences between a supercharger and a turbocharger: Power: A supercharger uses the engine's own power to drive a compressor for boosting. Consumption: The supercharger consumes engine power, and its speed changes with the engine speed, avoiding boost lag. It performs exceptionally well at low engine speeds but is limited by the engine's RPM, resulting in insufficient boost at high speeds. Exhaust: A turbocharger utilizes the engine's exhaust gases to drive a turbine in the exhaust pipe, which in turn drives a compressor in the intake pipe for indirect boosting, without consuming engine power. Speed: The turbocharger operates at extremely high speeds, providing several times more boost pressure than a supercharger. However, due to the inertia of the turbine and the significant resistance of the intermediate bearings, the turbine speed does not increase immediately when exhaust gases suddenly increase, leading to turbo lag.
