Turbo vs Supercharger: Which Adds More Power?

When it comes to adding power to your engine, forced induction is the way to go. Both turbochargers and superchargers can dramatically increase horsepower, but they do it in very different ways. Understanding these differences can help you make the right choice for your build.

How Turbochargers Work

Turbochargers use exhaust gases to spin a turbine that compresses intake air. This "free" energy from waste gases makes turbos incredibly efficient. Modern turbos can add 50-100% more power while actually improving fuel economy under light loads.

How Superchargers Work

Superchargers are mechanically driven by the engine's crankshaft through a belt or gear system. This direct connection means instant power delivery with no lag, but it also means the engine has to work harder to turn the supercharger.

Power Gains Comparison

Both systems can add substantial power, but the delivery is quite different:

• Turbos: Can add 40-80% more power efficiently, with some setups exceeding 100%
• Superchargers: Typically add 30-50% more power, with immediate delivery
• Peak power: Turbos generally win in ultimate power potential
• Usable power: Superchargers provide more consistent low-end grunt

Real-World Performance Differences

The choice between turbo and supercharger often comes down to how you drive and what you want from your car. Turbocharged cars excel on the highway and in situations where you can plan your acceleration. Supercharged cars shine in stop-and-go traffic and situations requiring immediate throttle response.
