The biggest advantage of a turbocharger is that it can greatly increase the power and torque of the engine without increasing the engine displacement. Generally speaking, the power and torque of the engine after adding a supercharger will increase by 20%. The disadvantage of the 30% turbocharger is lag, which is a slow response to sudden changes in the throttle due to the inertia of the impeller.
This is the purpose of compressed air. Most people still think that a supercharger will increase the fuel consumption of the engine, because the high-speed turbine requires a lot of energy to work. But the power of the supercharger is actually "using exhaust gas", which will definitely be produced when the internal combustion engine is running. Exhaust, an engine that makes thousands of revolutions per minute, emits massive amounts of gas at a very high frequency.
