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.
Accordingly, do all turbos flutter?
Most manufacturers eliminate turbo flutter through a component known as the blow-off valve (BOV). … While turbo flutter might make a lot of noise, it actually doesn’t do a thing for performance! That’s because it’s caused by backpressure after you release the throttle.
In this way, how do I get rid of turbo flutter?
How do I make my turbo whistle louder?
Is a BOV bad for your car?
The simple answer is NO! A Turbosmart BOV or BPV are designed and engineered to improve the performance of your turbocharger system and NOT damage your engine.
Is BOV flutter bad?
Unlike actual turbo flutter, this sound isn’t indicative of any kind of harsh or overly heavy use for your engine. If this is the noise that you associate as turbo flutter, then you’re in luck. Blow off release isn’t harmful to your engine or turbocharger in any way.
Is it normal for Turbo to whistle?
All turbochargers make some amount of noise – and most people don’t even notice it. However, if the whistling sound gets louder, more noticeable, or changes in any way, it could be symptomatic of a number of different problems, that all warrant further investigation.
Is no BOV bad?
Without a BOV, compressor surge can be a real problem on older, worn-out turbochargers — resulting in premature turbo failure.
Is turbo surge bad?
What does turbo flutter sound like?
When people think of turbocharged cars, one of the first things that comes to mind is the sound of turbo flutter, that fluttering/chattering sound which happens when the driver backs off the throttle in a hurry, such as when changing gear.
Why do turbos go Stustustu?
The basic concept behind this surge is when the incoming air has no place to be released once the throttle has been closed, which is normally done so through the blow-off valve, and then gets recycled back into the turbo.
Why does a turbo pop?
How are they created? Generally speaking, turbocharged cars can also create these sounds. The popping noises occur when ignition is retarded and unburnt fuel is sent into the exhaust system, where it combusts.
Why is my turbo fluttering?
Turbo flutter, also known as compressor surge, occurs when there is an abundance of pressurized air in the turbo system. When the engine is not able to combust the full amount of air pressurized by the turbocharger, this excess air will build up in the intercooler system.
