Which is better, A Supercharger or Turbocharger?

3 minutesread


Supercharger vs Turbocharger:

Both superchargers and turbos are forced induction systems which will add lots of power. But each system comes with its own set of benefits and drawbacks.



Superchargers Turbos
Immediate power delivery Delayed boost due to turbo lag
Less efficient as they run off power from the engine More efficient as they run off exhaust gases
Can cause more engine strain Not as easy to maintain
A most cost-effective way to boost hp and torque Better fuel economy
Power gains across wider RPM bands Power gains across narrow RPM bands (unless using a twin-turbo)



Either a supercharger or a turbo goes to administer you more power. once you get that power, however, will vary. Turbos are visiting have the tiniest punch at low RPMs. This can be because of turbo lag and since they spool slowly until the RPMs are high enough to spin the impeller.

Since a centrifugal supercharger is a belt-driven turbo, it’ll see an analogous curve and numbers throughout the powerband. Centrifugal superchargers and turbos make most of their power at the highest end of the facility band.

A twin-screw or Roots-type supercharger will offer you a more linear torque curve. Because they’re belt-driven and sit right on top of the engine, all the compressed gas goes immediately into the motor. This leads to increased power outputs but a similarly-shaped power curve thereto of a naturally aspirated engine.

So, a supercharger provides a moment boost, while a turbo has boost lag and must spool up before delivering power. The downside of a turbo is that you just don’t get that instant boost, but it’s more efficient than a supercharger. The supercharger must use power from the engine, which can use more fuel.



Turbos are getting a more popular option than superchargers because of their efficiency. Turbos are more common on economical cars searching for decent power but good mileage.

Automakers can use smaller four-cylinder engines with a turbo rather than a much bigger V6. And turbo V6 engines have started replacing larger V8s in many performance cars and trucks.



Superchargers provide good low-end torque and a linear curve throughout the powerband, which delivers reliable results. But superchargers can cause additional strain on the motor since they’re powered by the crankshaft. A turbo reuses exhaust gases that were visiting exit the car anyways, so there’s no additional engine strain.

Superchargers are easier to take care of though as you don’t should pander to wastegates or exhaust propulsion. They need their own contained oil system, while turbos share their oil supply with the engine.



Both superchargers and turbos will be quite expensive. Superchargers are usually costlier than turbos but require less maintenance. Turbos are more cost-effective and more fuel-efficient but may cost more to keep up.



Superchargers are usually louder than turbochargers. Superchargers typically make a whining sound, whereas turbos have that “whoosh” sound.


Which is better:

Both superchargers and turbos can help your engine produce more power. There are several different kinds of superchargers and turbos, so finding the correct one for you’ll rely upon your needs.

If you wish a second boost with no lag, a supercharger can be best. Superchargers can even get more power within a wider RPM band. Turbos are more efficient than superchargers, but they are doing have some lag time. They’re better for mid- or high-end power boosts.

But if you would like the most effective of both worlds, there’s always twin charging. Twin charging is when a car has both a turbocharger and a supercharger. Why pick one after you can have both!
