TURBOCHARGERS VS. SUPERCHARGERS: WHAT IS THE DIFFERENCE?

Drivers seeking a thrill tend to turn to vehicles outfitted with a turbocharger or supercharger. Both systems increase the amount of power an engine produces, ultimately improving performance in the process. However, each system does it in a different way, resulting in two unique driving experiences.

HOW TURBOCHARGERS IMPROVE PERFORMANCE

A turbocharger takes advantage of exhaust gas flow to improve engine performance. More specifically, a turbine stationed within the exhaust path powers an air compressor that increases the density of air before sending it into the engine. This pressurized air contains a greater amount of oxygen. Since an engine’s power is generated by the combustion of fuel and oxygen, the compressed air leads to a more powerful combustion cycle.

While a turbocharger can substantially increase the amount of energy generated by an engine, it takes a moment to respond to acceleration. For example, if a car accelerates from rest, the turbocharger will start to compress air and offer additional power once gases begin to flow. This effect produces a distinctive driving experience that many drivers enjoy because of the rapid shift in acceleration.

HOW TWIN TURBOCHARGERS FURTHER IMPROVE PERFORMANCE

Select high-performance vehicles offer twin-turbocharged engines, which utilize two turbochargers for even greater benefits.

Many twin-turbocharged configurations use slightly smaller turbochargers than those found in their single-turbocharger counterparts; since these turbochargers are lighter, they spin more easily and reduce the delay of acceleration. These smaller turbochargers can also be strategically positioned for better airflow management, ensuring more balanced air distribution to the cylinders; in turn, this can reduce the likelihood of fuel igniting prematurely which provides a smoother, more stable driving experience.

HOW SUPERCHARGERS AND E-SUPERCHARGERS IMPROVE PERFORMANCE

Like a turbocharger, a supercharger increases engine performance by compressing the air before it enters the engine. However, turbochargers differ from superchargers in power source.

A traditional mechanical supercharger is connected to the engine’s rotating crankshaft, and uses that torque to power its air compressor, which increases the density of air before it enters the engine chamber. Since the supercharger is directly attached to the crankshaft, it immediately responds to changes in engine speed and has no associated lag.

Alternatively, an e-supercharger functions extremely similarly to a mechanical supercharger, but is powered by an electric motor instead of the engine’s crankshaft. Since an e-supercharger functions independently of engine rpm, it significantly enhances the engine’s power when accelerating from rest or driving at a lower engine speed.

WHICH IS BETTER: A TURBOCHARGER OR A SUPERCHARGER?

Turbochargers and superchargers both provide significant enhancements to engine performance, making them excellent options for those seeking a dynamic driving experience. However, each offers its own unique advantages.

Consider a turbocharger if: you are looking for a significant boost in performance with minimal additional fuel consumption.

Turbochargers typically offer a greater maximum increase in power than superchargers, making them ideal for drivers seeking the largest possible enhancement in performance. Since they’re powered by exhaust, they typically maximize power with a minimal increase in fuel consumption. Turbochargers do experience a degree of lag compared to superchargers which provides them with a distinctive driving experience that many drivers enjoy, particularly when it comes to sudden acceleration.

Consider a supercharger or e-supercharger if: you are looking for a responsive, noticeable boost in performance.

Superchargers and e-superchargers provide a highly responsive increase in performance, making them ideal for those seeking a powerful, precise driving experience. While both superchargers and e-superchargers offer a greater increase in performance at low speeds compared to a turbocharger, e-superchargers are an attractive option for drivers looking to maximize their vehicle’s performance independently of engine speed.

Consider both a turbocharger and an e-supercharger if: you are looking for extreme performance improvement at all engine speeds.

Select performance vehicles, including the Genesis G90 and Genesis GV80 Coupe, include both a turbocharger (or, in the case of these two vehicles, twin turbochargers) and an e-supercharger for greater maximum power across all engine speeds. The e-supercharger enhances performance at low speeds, while the turbocharger takes over at higher speeds to provide even larger increases in performance.

FREQUENTLY ASKED QUESTIONS (FAQ)

If you still have questions about turbochargers or superchargers, please consult our list of frequently asked questions below.

WHAT IS A TURBOCHARGER?

A turbocharger is a device that enhances an engine’s performance by channeling the force of waste gas exhaust to compress air before it enters the engine; this compression increases the amount of available oxygen in each cylinder, which in turn increases the amount of force generated during the combustion process.

WHAT DOES A TURBOCHARGER ACTUATOR DO?

A turbocharger actuator monitors the pressure of a turbocharged engine and regulates its performance by diverting exhaust gas away from the turbocharger’s turbine. This process ensures that pressure remains within a safe range while offering the greatest performance benefits.

WHAT IS A SUPERCHARGER?

A supercharger is a device that enhances an engine’s performance by using the torque generated by the crankshaft to compress air before it enters the engine; since more oxygen is available for each combustion event, the engine can generate a greater amount of power.
