If you ask a car enthusiast whether they prefer turbochargers or superchargers, most likely they’ll choose the former. And for a good reason. Turbos are simply better than superchargers. They provide more power, better fuel economy, and they’re generally easier to install than superchargers.
The main advantage of turbochargers over superchargers is in the efficiency of the system. While superchargers are driven directly by the engine, turbos use exhaust gas flow to drive the turbine wheel, which in turn, spins the compressor wheel. This means that turbochargers extract more energy from the exhaust gases than superchargers, and that translates into more power output.
Moreover, turbos are renowned for their fuel efficiency. The reason is that they’re not driven by engine power, like superchargers, which require a lot of energy to spin. Instead, they’re run off exhaust gas flow, which would otherwise be wasted. Therefore, it’s not uncommon for turbocharged cars to deliver more power while consuming less fuel than supercharged ones.
The difference between turbos and superchargers
Both turbos and superchargers are devices that increase the power output of an engine. However, there are significant differences between the two.
A turbocharger uses exhaust gases from the engine to spin a turbine, which in turn drives a compressor that forces air into the engine. This process is known as forced induction. A supercharger, on the other hand, is driven by a belt connected to the engine’s crankshaft, and it compresses air and feeds it directly into the engine.
Here are some key differences between turbos and superchargers:
- Turbochargers are typically more efficient than superchargers, as they use waste energy from the exhaust gases to generate boost. This means that they do not put as much of a load on the engine, resulting in better fuel economy and less wear and tear on the engine.
- Superchargers, being belt-driven, produce boost as soon as the engine is running, whereas turbos need a certain amount of exhaust gas flow before they start to generate significant boost. This means that superchargers provide more immediate power delivery, whereas turbos generally have a slight lag.
- Turbochargers can generate more boost than superchargers, which means that they can produce more power. However, this also means that they can put more stress on the engine, which can lead to reliability issues if the engine is not built to handle the extra pressure.
- Superchargers tend to be less complex than turbochargers, which can make them easier to install and maintain. They also make a distinctive whine or growl, which some enthusiasts find more exciting than the whistling sound of a turbocharger.
How turbos and superchargers work
Before we dive into the advantages and disadvantages of turbos and superchargers, it’s important to understand how they work. Both turbos and superchargers are forced induction systems that increase the amount of air flowing into the engine, resulting in more power. However, the way they achieve this differs.
- Turbos: A turbocharger is essentially a turbine driven by exhaust gases that compresses the intake air, which is then fed into the engine. The turbo is connected to the engine’s exhaust system and intake system via a turbine and a compressor, respectively, creating a closed circuit. As exhaust gases flow over the turbine blades, they spin, causing the compressor to spin as well. The compressor takes in outside air and compresses it before sending it to the engine. The result is an increase in horsepower and torque.
- Superchargers: A supercharger, on the other hand, is belt-driven by the engine and uses a compressor to force air into the engine’s intake manifold. Superchargers come in two main types: positive displacement and centrifugal. Positive displacement superchargers provide a consistent boost of pressurized air throughout the operating range, while centrifugal superchargers provide a boost that increases with engine speed.
Turbos vs Superchargers: Which One is Better?
Now that we know how turbos and superchargers work, let’s compare them. There are a few key factors to consider when choosing between the two:
- Cost: Turbos are generally less expensive than superchargers due to their simpler design and lack of additional components.
- Fuel Efficiency: Turbos increase fuel efficiency by allowing smaller engines to produce more power, while a supercharger can decrease fuel efficiency due to increased operating temperatures and additional power demands.
- Power Delivery: Turbos can have a delay in power delivery at lower revs (known as turbo lag), while superchargers provide immediate power throughout the entire operating range of the engine.
- Aftermarket Options: Both turbos and superchargers have a vast array of aftermarket options for performance upgrades, but superchargers tend to have a wider variety due to their simple design.
Ultimately, the choice between a turbo and supercharger depends on the specific needs and wants of the vehicle owner. Both have their own unique advantages and disadvantages, and it’s up to the owner to decide which one suits their vehicle and driving style better.

Pros and cons of using a supercharger
Superchargers and turbochargers serve the same purpose, to boost the engine’s power output. However, superchargers and turbos operate differently. Superchargers are belt-driven and draw power off the engine to compress air and force it into the engine. The compressed air results in an increase in power and torque. Here are some pros and cons of using a supercharger:
- Pros:
- Immediate power – Unlike turbos, superchargers provide an immediate boost in power and torque because they operate by drawing power from the engine’s crankshaft. Since there are no lag times in building boost pressure, superchargers provide a more immediate power delivery.
- Efficient at lower RPMs – Superchargers are more efficient at lower RPMs, providing more linear power delivery. This is ideal for everyday driving, as it provides more accessible power throughout the rev range.
- Simplicity – Superchargers are relatively simple in design, consisting of a compressor, pulley, and intercooler. They are less complex than turbochargers and require less maintenance.
- Cons:
- Limited power gains – Superchargers are less efficient than turbochargers at compressing air. This results in limited power gains and a higher power ceiling. Turbochargers can generate more power by compressing more air into the engine, resulting in a higher power output.
- Loss of power – Superchargers put an additional strain on the engine, reducing its efficiency and causing a loss of power. When driving aggressively, the added load can cause a reduction in engine power over time.
- Increased heat – Compressing air generates heat, and superchargers add more heat to the engine bay than turbos. This results in higher engine bay temperatures and increased risk of heat soak.
In summary, superchargers provide an immediate boost in power and are more efficient at lower RPMs. However, they have limited power gains compared to turbochargers and can cause a loss of power and increased heat. Before deciding between a supercharger or turbocharger, it is essential to consider your driving goals and priorities.
Tuning options for turbos vs superchargers
One of the biggest benefits of turbochargers over superchargers is the range of tuning options available. While both provide significant power boosts, turbos have the capability to deliver much higher power outputs due to their ability to compress more air and fuel into the engine. Let’s take a closer look at some of the ways turbos and superchargers differ in terms of tuning options.
- Boost control: With a turbocharger, you have more control over boost pressure. This is because the wastegate can be adjusted to restrict exhaust flow and make the turbine spin slower, reducing boost pressure. Similarly, the wastegate can be opened further to allow more exhaust flow, increasing boost pressure. Superchargers, on the other hand, typically run at a fixed boost level, so you don’t have as much control over boost pressure.
- Intercooler options: Because turbos compress air using a turbine, they tend to get hotter than superchargers. This means that intercoolers are crucial for turbocharged engines to keep the intake air temperature at a safe level. There are a range of intercooler options available for turbos, from air-to-air intercoolers to water-to-air intercoolers. Superchargers also benefit from intercoolers, but the options are more limited.
- Turbo size and spool: Another advantage of turbos is that they come in a range of sizes, which allows for greater flexibility in terms of tuning. Smaller turbos generally spool up quicker and provide faster low-end power, while larger turbos take longer to spool but can deliver more top-end power. This means that you can tailor your turbo selection to the specific needs of your engine. Superchargers, on the other hand, tend to be fixed in size and provide a more linear power delivery.
Overall, while both turbos and superchargers can provide significant power gains, the greater range of tuning options available with turbos gives them the edge in terms of performance potential.
| Turbochargers | Superchargers | |
|---|---|---|
| Boost control | Highly adjustable | Fixed |
| Intercooler options | Wide range available | More limited |
| Turbo size and spool | Range of sizes available | Fixed size |
There’s no denying that both turbos and superchargers have their place in the world of performance upgrades. However, if you’re looking for greater tuning flexibility and a wider range of options, a turbocharger might be the way to go.
