Is turbo flutter bad for your 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.
Are turbos supposed to flutter?
That fluttering noise is the sound of a turbo operating in compressor surge, as the compressor ‘chops’ through the air rather than pushing the air into the engine. Love it or hate it, it’s doing nothing good for your turbocharger performance or reliability. This is where a blow-off valve comes into its own.
What does it mean when your turbo flutters?
Turbo flutter, also known as compressor surge, occurs when you step off the accelerator after achieving peak boost. While the engine shuts off airflow, all the pressure from the turbo is still there — looking for somewhere to escape.
How do I increase turbo lag?
How to Reduce Turbo Lag
- Replace your turbo vehicle’s exhaust downpipe with a smaller-diameter unit. A downpipe with a smaller inner diameter offers less airflow, slightly reducing top-end horsepower.
- Replace your stock blow-off valve with an aftermarket unit.
- Purchase a new intercooler kit for your turbo vehicle.
What’s the sound of a turbo flutter engine?
The sound of a turbo fluttering can be alarming for people used to naturally aspirated engines. Turbo flutter is sometimes described as “pigeon noises” or written out as “stu-tu-tu.” Both of these are pretty good descriptions of the sound, but what actually is turbo flutter? Turbo flutter is another name for compressor surge.
What’s the difference between turbo flutter and wastegate chatter?
The “wastegate chatter” rumor would lend credence to the opinion that turbo flutter indicates high performance. While wastegate chatter is a turbo-specific noise, it is different than turbo flutter. Wastegates can either be internal or external to the turbocharger.
What’s the difference between turbo flutter and compressor surge?
Turbo flutter is another name for compressor surge. So, Is Turbo Flutter Bad? 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.
Why does my car make noise when I Turn on the Turbo?
That noise may tell the world you have a turbo, but the truth is, the sound signals a problem. Turbochargers are our friends, we shouldn’t let them suffer! A turbocharger is an air pump, that is, it is a mechanical component that pushes air.
