Turbocharger Or Supercharger – They Both Squeeze Out More Power

So, The biggest difference between a turbocharger or supercharger; is their source of energy:

  • Consequently, the flow of exhaust gases driving a turbine in a turbocharger.
  • While, a belt or chain-drive from the engine’s crankshaft drive a supercharger.

So, In the old days, a high-performance or racing application; wanting more power, relied on a turbocharger or supercharger. Although superchargers still play a big part of the automotive industry; they’re not part of the focus on fuel economy. As a result, most automakers have leaned towards; turbochargers for their fuel economy benefits.

Today, Everything from sedans to light-duty trucks feature a turbocharger option; or is already a factory default.

Consequently, Allowing drivers to enjoy that extra horsepower, from a smaller fuel-efficient engine. Regardless of the application, using a turbocharger or supercharger creates extreme operating conditions; placing more stress on the engine.

Have you ever wondered what the advantages of a turbocharger or supercharger are ?

When designing an engine to pull in more than atmospheric pressure; tuners often turn to forced induction. Because, It’s one of the fastest ways, to add significant power to almost any engine.

So, What is the difference and why have automakers leaned towards turbochargers. Mostly, because of the pros and cons of one over the other in today’s applications. So, A turbocharger is driven by exhaust gas. Alternatively, A supercharger is driven by the crankshaft of an engine.


Turbocharger Advantages:

  • Allows for smaller engine displacements, to produce much more power relative to their size. Smaller engines use less fuel to idle; and have less rotating and reciprocating mass, which improves fuel economy.
  • Turbochargers run off exhaust energy that is typically lost. Consequently, The recovery of this energy improves the overall efficiency of the engine.

Turbocharger Disadvantages:

  • Turbochargers, especially large turbochargers, take time to spool up and provide useful boost.
  • For traditional turbochargers, they are often sized for a certain (RPM) range. Consequently, where the exhaust gas flow is adequate, to provide additional boost for the engine. They typically do not operate across as wide an (RPM) range as superchargers.
  • In some turbocharger applications, especially with larger turbos; reaching the boost threshold can provide an almost instantaneous surge in power. As a result, compromising traction or causing some instability of the vehicle.
  • also, Turbochargers get very hot and often tap into the engine’s oil supply. This calls for additional plumbing; and is more demanding on the engine oil.

Supercharger Advantages:

  • Adding a supercharger to any engine is a quick solution to boosting power.
  • The superchargers biggest advantage over a turbocharger is that it does not have any lag.
  • Good power at low (RPM) in comparison with turbochargers.

Supercharger Disadvantages:

  • The biggest disadvantage of superchargers is; that they suck engine power simply to produce engine power.
  • The crankshaft drives the turbo. So, you’re essentially powering an air pump with the engine power. Because of this, superchargers are significantly less efficient than turbochargers.

Finally, The main difference between the turbocharger and the supercharger lies in its power supply. So, That’s why turbochargers are the choice of today’s automakers.
