Does Flutter hurt the turbo?

When the compressed air has nowhere to go, it causes the turbo rotational speed to rapidly drop, and attempts to push against the wheel. This can cause premature wear on your turbo, however closed throttle flutter on modern turbochargers is unlikely to cause a noticeable drop in turbocharger lifespan.

How do you fix a turbo Flutter?

Conversely, if you’re trying to eliminate turbo flutter, the best thing you can do is install a blow-off valve or replace yours if it isn’t working correctly. Almost every vehicle with a turbo comes with a blow-off valve, and if it’s working properly, you won’t get any significant turbo flutter.
