Supercharger vs. Turbocharger - Which Is Better?

Supercharger vs. Turbocharger - Which Is Better? | B & L Automotive

Are you torn between choosing a supercharger or a turbocharger for your vehicle? If so, you're not alone. The debate between these two forced induction systems has been raging for years, with enthusiasts on both sides passionately defending their preferred choice.

Understanding Superchargers

Superchargers are mechanical devices that compress air and force it into the engine's combustion chambers. They are typically driven by a belt connected to the engine's crankshaft, allowing them to deliver immediate power and throttle response. Superchargers are known for their linear power delivery, providing consistent performance across the entire RPM range. However, they can be parasitic, drawing power from the engine to operate, which can affect fuel efficiency.

Understanding Turbochargers

On the other hand, turbochargers are exhaust-driven compressors that utilize exhaust gasses to spin a turbine, which in turn drives a compressor wheel. Turbochargers harness wasted energy from the exhaust to boost engine power without sapping additional power from the engine. They offer excellent efficiency and can provide significant power gains, especially at higher RPMs. However, turbochargers suffer from "turbo lag," a delay in power delivery caused by the time it takes for exhaust gasses to spool up the turbine.

Pros and Cons of Superchargers


  • Immediate power delivery
  • Linear power curve
  • Simpler installation compared to turbochargers


  • Parasitic drag on the engine
  • Limited power potential compared to larger turbo setups

Pros and Cons of Turbochargers


  • Improved fuel efficiency
  • Greater power potential
  • No parasitic drag on the engine


  • Turbo lag
  • Complex installation and potential heat management issues

Which Is Better for Performance?

When it comes to performance, both superchargers and turbochargers have their strengths. Superchargers excel in providing instant power delivery and consistent performance, making them ideal for applications where immediate throttle response is critical, such as drag racing or street driving. 

On the other hand, turbochargers offer excellent efficiency and the potential for significant power gains, especially in high-performance applications where top-end power is essential.

Which Is Better for Daily Driving?

For daily driving, turbochargers may have the edge due to their superior fuel efficiency and potential for lower emissions. Turbocharged engines can deliver impressive power when needed while maintaining reasonable fuel economy during normal driving conditions. However, modern supercharger systems have become more efficient and refined, making them viable options for daily drivers as well.

Questions You Might Have

Which is better for drag racing, a supercharger or a turbocharger?

Superchargers are typically preferred for drag racing due to their immediate power delivery and consistent performance off the line.

Can I install a supercharger or turbocharger on any car?

In most cases, yes, both superchargers and turbochargers can be installed on a wide range of vehicles, depending on compatibility and available space under the hood.

Are superchargers or turbochargers more expensive to install?

The installation cost can differ based on the type of vehicle and the complexity of the setup. Turbocharger installations usually require more components like intercoolers and exhaust modifications, making them more complex and expensive compared to superchargers.
