Which is better, supercharger or turbocharger?

[BryceLee]

Both supercharging methods have their own advantages and disadvantages. The following are the differences between a supercharger and a turbocharger: 1. Power: A supercharger uses the engine's own power to drive a compressor for boosting. 2. Consumption: The supercharger consumes the engine's 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 speed, resulting in insufficient boost at high engine speeds. 3. Exhaust: A turbocharger utilizes the exhaust gases produced by the engine to drive a turbine in the exhaust pipe, which in turn drives a turbine in the intake pipe for indirect boosting, without consuming the engine's power. 4. Speed: The turbocharger operates at extremely high speeds, providing several times higher 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 simultaneously when exhaust gases suddenly increase, which is known as turbo lag.
