What Are the Differences Between Turbocharger And Supercharger?

Sometimes there’s a little confusion between the turbocharger and the supercharger, because the presence of “chargers” in their names making it easy to perceive turbochargers and superchargers as interchangeable engine components.But there are a few important differences, and they’re at different ends of the vehicle spectrum.

What Is Turbocharger?

A turbocharger is a device that increases the efficiency and power output of an internal combustion engine by compressing the air entering the combustion chamber. It consists of a turbine connected to a compressor, both of which are housed in a single unit. The turbine is driven by exhaust gases from the engine, which spin the compressor, compressing the intake air and delivering it to the engine at a higher pressure. This compressed air allows for more fuel to be burned, resulting in increased power and efficiency compared to a naturally aspirated engine. Turbochargers are commonly used in both gasoline and diesel engines to improve performance.

What Is Supercharger?

A supercharger is a forced induction system used in internal combustion engines. It directly increases engine power by compressing intake air with power from the engine’s crankshaft.

How to Install turbocharger and supercharger?

Installing a turbocharger involves mounting it onto the exhaust manifold, connecting oil lines for lubrication, and installing intake and exhaust piping. Tuning is then necessary for optimal performance. Installing a supercharger entails mounting it onto the engine block or intake manifold, installing drive belts, and potentially an intercooler. Tuning is also required for best results. Professional expertise is advised for both installations.

Which is more efficient, turbocharger or supercharger?

You’re more likely to find a fuel efficient vehicle powered by a turbocharger than a supercharger.

One the one hand, turbochargers utilize waste energy from the engine’s exhaust gases to power the turbine, while superchargers are typically belt-driven and draw power directly from the engine. This means that turbochargers do not consume engine power to operate, making them more efficient in terms of power delivery. On the other hand, turbochargers often offer better control over boost pressure through wastegates and variable geometry turbines, allowing for more precise tuning and optimization of engine performance.

Which is louder turbocharger or supercharger?

In general, superchargers tend to produce more audible noise compared to turbochargers. 

This is because superchargers are directly connected to the engine’s crankshaft and operate at engine speed, causing them to produce a whining or whistling sound that increases with engine RPM. On the other hand, turbochargers are driven by exhaust gases and can be quieter, especially at lower engine speeds. However, some turbocharged setups, particularly those with larger turbos or modified exhaust systems, can produce noticeable turbocharger whine or spooling sounds. Ultimately, the perceived loudness of either system can vary depending on factors such as the type of supercharger or turbocharger, the design of the intake and exhaust systems, and any aftermarket modifications.

Which is response quickly turbocharger or supercharger?

Superchargers typically offer quicker throttle response compared to turbochargers. Here’s why:

Instant Power: Superchargers are mechanically driven by the engine’s crankshaft, so they generate boost and provide immediate power delivery as soon as the engine is running. There’s no lag time waiting for exhaust gases to spool the turbine, as with turbochargers.

Direct Power Delivery: Since superchargers are belt-driven and connected directly to the engine, they respond instantly to changes in throttle input. As soon as you press the accelerator, the supercharger begins to spin faster, increasing airflow and delivering power to the engine without delay.

No Lag: Turbochargers rely on exhaust gases to spin the turbine, which can cause a delay in power delivery known as turbo lag. This lag is typically more noticeable at lower engine speeds or when initially accelerating from a standstill. In contrast, superchargers don’t suffer from this lag, providing immediate throttle response across the engine’s rpm range.

Overall, if immediate throttle response and instant power delivery are priorities, a supercharger may be a preferable option over a turbocharger.

Which is cheaper to maintenance turbocharger and supercharger?

In general, turbochargers tend to be cheaper to maintain compared to superchargers. Here’s why:

Simplicity: Turbocharger systems typically have fewer moving parts compared to superchargers. Turbochargers consist mainly of a turbine, compressor, and associated plumbing, whereas superchargers include additional components such as belts, pulleys, and bearings for the drive system. This simplicity often translates to lower maintenance costs for turbochargers.

No Belts: Turbochargers are not belt-driven like superchargers, so there’s no need to regularly inspect, adjust, or replace belts. Belt-driven superchargers require periodic maintenance to ensure proper tension and alignment, as well as replacement if they wear out or break.

Less Heat: Turbochargers tend to generate less heat compared to superchargers since they are not directly connected to the engine’s crankshaft. Excessive heat can accelerate wear on components and increase the likelihood of failures, so lower heat generation can contribute to reduced maintenance costs.

Long Service Time: Turbochargers are often more durable and have longer service intervals compared to superchargers. With proper maintenance and care, turbochargers can last the life of the vehicle, whereas superchargers may require more frequent servicing or replacement over time.

Overall, while both turbochargers and superchargers require some level of maintenance, turbocharger systems typically have lower maintenance costs and longer service intervals compared to superchargers.

What are the applications of turbochargers and supercharger?

Turbochargers are commonly used in automotive and some aerospace filed, while superchargers are commonly used in high-performance cars and some motorcycles.


Turbocharger is a better choice for those who want to balance performance with fuel economy and efficiency.Supercharger is more likely to be the way to go for those who are more interested in a simple solution for raw power.
