Turbocharger Vs Supercharger | Difference

Turbochargers and superchargers are forced induction devices to boost the engine's power output. Both systems employ air compression to increase the volume of air entering the engine, allowing more fuel to be burned and more power to be generated. However, a few key differences place them on opposing extremes of the automotive spectrum. Let us check out the turbocharger vs supercharger in detailed information explained here.  

The main difference between turbochargers and superchargers

The main difference between turbochargers and superchargers is how they compress air. A turbocharger uses engine exhaust gases to power a turbine, compressing and driving air into the engine. A supercharger is driven by the engine and uses a belt-drive or gear-drive system to compress air.

Turbochargers are more efficient than superchargers in terms of performance since they work at lower RPMs and may create more power. On the other hand, superchargers provide more power at lower RPMs, making them suitable for drag racing and other short-burst applications.

Turbocharger Vs Supercharger

  • Superchargers produce significantly more horsepower than turbochargers. 
  • Turbochargers are ideal for smaller displacement engines with four-cylinder applications, whereas superchargers boost power in larger displacement engines with more cylinders. 
  • Supercharger experiences longer life and less heat wear than a turbocharger. 
  • Turbocharged engines require higher engine oil than supercharged engines due to extremely hot operating temperatures. 
  • Supercharged engine power delivery is more instantaneous than a turbocharged engine because no power lag was seen with turbocharging. 
  • The supercharged engine has lower fuel economy than the turbocharged engine. 
  • Supercharger engines are louder and more abrasive sounding than turbochargers. 

Which one do you prefer Turbocharger or Supercharger?

Turbochargers make more sense since they boost engine efficiency in various ways. Even if they can provide an effective boost at low RPM, superchargers place additional strain on the engine. However, if you can not decide, you can utilize both concurrently, known as twin-charging.

Where will things head in future?

Electric turbos, in which an electric motor spools up the turbo at low RPMs, creating an effective boost until the exhaust gases are sufficient to power the turbo, are projected to become increasingly popular in future automobiles. This is exactly what the ERS system is doing in Formula One, and it is the solution to the turbocharger's worst problem turbo lag.
