The Different Types of Turbocharger Systems and their Relative Advantages

It is necessary to understand the different types of turbo systems in the world of automobiles. This involves knowing the variations that exist between single systems, twin-scroll systems, twin systems, electric turbo systems, and variable geometry. The various types of turbocharger systems and styles include single turbo, twin turbo, twin scroll turbo, variable geometry turbo, electric turbo, and variable twin scroll turbo. Here is a helpful, detailed discussion about a few of these systems and their best advantages.


This type of turbo has limitless variability with different turbine and compressor wheel size. This variability is responsible for the different torque characteristics observed in vehicles. Larger turbocharger systems generate high top-end power, while smaller turbocharger systems generate low-end power as they move faster. Additionally, there are journal bearing and ball bearing single turbocharger systems. Ball bearing turbo systems generate less friction for the turbine and compressor to spin on allowing a faster spool.


  • Offers a simple and easiest turbocharging options when it comes to installation
  • Offers an inexpensive option of increasing efficiency and engine power of your vehicle 
  • Gives room for using smaller engines to produce same amount of power as larger ones reducing the weight of your vehicle

Twin-Turbo Charger System

Plenty of options exist when using two turbochargers just like single turbo systems. The system is designed with a single turbocharger for each cylinder blank.


  • The system provides a much wider and flat torque curve. This allows a low-end torque with high power for your vehicle than small single turbocharger systems.

Twin Scroll Turbo Charger System

These systems are better in nearly every all aspects than other types like single scroll turbochargers. The use of two scrolls divides the exhaust pulses preventing interference of exhaust pressure from one cylinder to another. This allows maximum power and efficiency of your vehicle's performance.


  • Allows more energy dispensation to the exhaust turbine
  • Allows more valve overlap with no exhaust scavenging hampering, which ensures more flexibility when turning

Electric Turbocharge Systems

With a powerful electric motor, nearly all of the drawbacks of turbo systems are eliminated. These types of systems are entirely free from turbo lag, insufficient exhaust gases and a lack of low-end torque production.


  • Connecting an electric motor to your exhaust turbine recovers most of the wasted energy in your vehicle increasing its performance and efficiency
  • Electric motor connection offers an even torque throughout the ride
