What is the difference between turbocharging and supercharging?

[McAnderson]

The differences between turbocharging and supercharging are: 1. Different power output: Turbocharging has turbo lag, and the power delivery is relatively less linear; supercharging provides a linear output close to natural aspiration. 2. Different operating speeds: The turbocharger operates in an ultra-high speed range of over 10,000 rpm; the supercharger operates at speeds well below 3,000 rpm. 3. Different characteristics: Turbocharging maintains the original form of engine components without the need for additional high-cost precision parts; supercharging increases engine power output by 20% to 40%, does not burden the maintenance system, achieves environmental protection, fuel efficiency, and high efficiency goals, and significantly saves new engine development costs.
