Why do turbo engines sound different?

A turbo can make a few different noises. Firstly they rotate at pretty high speeds and tend to produce a fairly high pitched whine or whistle once they get up to speed. The blow-off valves which vent excess pressure can also make a noticeable hissing sound.

Are superchargers louder than turbos?

Superchargers are arguably more reliable than turbochargers. They’re easy to install and maintain. They’re louder than turbochargers—they enhance the RPMs by a considerable amount—and they’re also more common as a result.

What makes the supercharger whine?

Centrifugal superchargers provide the most efficient air compression system, and they’re the ones typically found in most vehicles. The sounds that they make can turn heads on the busy street! When the compressed air leaves the discharge outlet, the supercharger creates a whistling, whining sound.

Why do turbochargers make that sound?

Compressor surge occurs when a turbocharger is operating at peak boost and then the gas is let off, closing the throttle body. This traps air, which then exits back out through the turbocharger causing the compressor to spin. If the gas is released at the redline, you’ll hear crackles from the exhaust as well.

Do turbos reduce exhaust noise?

The turbo has a similar effect on exhaust systems, where the exhaust-side impeller disrupts the exhaust flow by creating an extra gate for the sound to have to flow through. The turbo also tends to make the exhaust quieter as a byproduct.

Do turbos whistle?

As the name suggests, a turbo whistle sounds like a high pitched whistle or whining sound, heard when the turbocharger kicks in as you accelerate and the revs go up. For some people, a turbo whistle can be annoying, but to others, it’s actually desirable!

What does a bad supercharger sound like?

This sound will be similar to a knocking engine or a loose rocker arm, and will increase in volume as the blower accelerates. If you hear this ticking sound coming from the motor, pull over and inspect the supercharger belt for any frays, strings or excess rubber that might be coming apart.

Does a supercharger change exhaust sound?

Premium Member. All a supercharger does is pressurize the intake manifold. That’s it. The only way your exhaust tone will change is due to the fact you’re lighting off a much larger volume of air and fuel by weight, thus flowing more exhaust gasses.
