Many people tend to focus solely on a turbocharger’s maximum boost limit, but that isn’t the only factor that affects performance. Turbo turbines affect a turbocharger’s efficiency and power output. Discover the relationship between turbo turbines and performance and why choosing the right type of turbine for your turbocharger matters.
What Is a Turbocharger Turbine?
A turbocharger has two main parts—the compressor and the turbine. The turbine drives the compressor powered by exhaust gases from the engine.
The turbine in a turbocharger is either radial or axial. The difference lies in the turbine’s blade orientation; radial turbines point outward from the center, while axial turbines run parallel to the shaft.
The Importance of Turbine Size
The size and design of the compressor and turbine can help you determine your turbocharger’s efficiency. A large turbine wheel allows for more exhaust gas flow and boost pressure. However, a larger wheel also means more inertia, requiring more energy to get it moving. This translates into more lag—a slower response.
On the other hand, a small turbine wheel has less inertia, resulting in less lag. However, it may not be able to handle a more exhaust flow. In that case, it produces less of a boost.
The Turbine Design
A turbocharger’s turbine design creates a balance between power and efficiency. Modern turbines tend to have greater blade angles and streamlined designs, which help the gases flow smoothly through the wheel. The engine’s exhaust temperature may decrease with better airflow, resulting in better fuel efficiency and a longer engine lifespan.
What To Look for When Choosing a Turbine
Consider your turbo turbine’s application in the car and the engine’s size. A small turbine is best for low RPMs for street driving, while a large turbine suits high RPMs for racing.
Additionally, the turbine should be able to handle the maximum exhaust gas pressure the engine generates without being overly restrictive. A knowledgeable mechanic can assist you in selecting the perfect turbine for your vehicle.
You should also consider the turbocharger manufacturer, as different brands have various housing inlets for turbines, such as the Cummins turbo parts, which typically have large housing.
A turbocharger can improve your car’s efficiency, power output, and acceleration. Understanding the relationship between turbo turbines and performance is crucial for finding the best option for your vehicle. You can experience a significant upgrade in fuel efficiency, engine longevity, and driving experiences with the right turbocharger!
