Is compressor surge bad for the turbo?
Since the turbo is actually making significant boost, is at high RPM, and the pressure is fluctuating wildly because of the surge, these conditions do have the potential to cause greatly accelerated turbo bearing wear and/or damage to the compressor wheel.
What causes turbo compressor surge?
Hence, the turbocharger surging is a result of various engine parts not performing in sync. A worn-out engine cylinder or fuel system may lead to problems in the engine and the turbocharger. This will result in less airflow to the compressor against the higher back pressure, making the compressor surge.
What causes turbo fluttering sound?
While the engine shuts off airflow, all the pressure from the turbo is still there — looking for somewhere to escape. The only available path of least resistance is straight back through the turbo and so this backpressure is what causes turbo flutter.
Is turbo flutter and compressor surge the same thing?
Both turbo flutter and compressor surge occur when the air pressure after the turbo is higher than what the turbo can maintain. The difference is that compressor surge occurs while you’re on the throttle and compressor blades in the turbo stalls.
How do I make my turbo whistle louder?
3 Ways To Make Your Turbo Louder | Now You Know – YouTube
Is 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.
How do I stop my compressor from surging?
Surge can be prevented by providing an anti-surge valve, which allows more flow to be recycled back to the suction side and enables moving the compressor operating point away from the surge line.
What does a faulty turbo sound like?
Loud noises: If your vehicle has a bad turbo, you may hear loud noises that sound like whining or screeching. So if your vehicle is running and you hear a loud whining sound that increases in volume as the problem goes unfixed, this is most likely to do a turbo problem.
Does turbo flutter damage?
Does turbo flutter damage your turbo?
How do I make my turbo flutter louder?
HOW TO GET LOUD TURBO FLUTTER WITH SCREAMER PIPE …
Does cold air intake make turbo louder?
The sound of your car will be louder and more aggressive with a cold air intake. Instead of loudness though, a cold air intake changes the sound of your car engine. You will clearly hear the sound of air flowing into the intake – especially when you rev up the car and then release the throttle.
Do turbo whistles work?
It works. It doesn’t blow off, all it does is whistle, but it works. MAKE SURE you read the measurements on this thing before you buy. I bought it and ended up having to do alot of work trying to get a good enough flow for it to work because my aftermarket muffler was way too big.
How do you detect a compressor surge?
Generally speaking, a surge will be the result of a sudden and significant change in the compressors’ flow function. To detect a surge, measurements of discharge pressure, inlet temperature, and compressor flow should be taken. The compressor’s suction pressure can also indicate a surge-based oscillation.
What do you mean by compressor surge?
Compressor surge is a form of aerodynamic instability in axial compressors or centrifugal compressors. The term describes violent air flow oscillating in the axial direction of a compressor, which indicates the axial component of fluid velocity varies periodically and may even become negative.
What are the signs of a blown turbo?
What are the signs of a blown turbo?
- The car has noticeable power loss.
- The acceleration of the car seems slow and noisy.
- The car doesn’t easily maintain high speeds.
- There is smoke coming from the exhaust.
- There is an engine fault light on the dashboard.
How do I know my turbo is bad?
The symptoms of a damaged or failing turbo are:
- Loss of power.
- Slower, louder acceleration.
- Difficulty maintaining high speeds.
- Blue/grey smoke coming from the exhaust.
- Engine dashboard light is showing.
Should a turbo whistle when letting off throttle?
It’s called compressor surge. It happens when there’s not enough pressure to open the blow off valve, and the slight flutter you hear is air hitting the compressor blades. Nothing to worry about unless maybe if happens after WOT in boost.
Are whistle tips illegal?
Whistle Tips
These aren’t exactly new, but they were recently popularized by a KRON-TV interview with Oakland resident Bubb Rubb and his imitation of the whistle tip screeching. Regardless, these devices are illegal in California.

How does compressor anti surge work?
These valves detect when a process compression stage is approaching to surge and subsequently take action to reverse the movement of the operating point towards the surge line. This decreases the plenum pressure and increases the flow through the compressor, resulting in stable working conditions.
How do you control a compressor surge?
What is the difference between compressor stall and surge?
A compressor stall is a local disruption of the airflow in the compressor of a gas turbine or turbocharger. A stall that results in the complete disruption of the airflow through the compressor is referred to as a compressor surge.
What should a turbo sound like?
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!
How long should a turbo last?
around 150,000 miles
Turbos are designed to last the lifetime of the vehicle (or around 150,000 miles); however, it’s possible for them to wear out over time depending on how hard you drive the car and the original build quality of the turbo.
