What causes turbo whistle? Turbo whistle is the sound of the compressor inside the turbocharger speeding up (also known as ‘spooling up’, which is why it kicks in at the boost threshold (when the turbo starts to kick in) as you accelerate up the rev range.
What does it mean when your Turbo whistles?
A “turbo whistle” usually indicates a worn and failing turbo bearing, which is pretty much all there is to go wrong with a turbo. What would causes a whistling noise while driving?
Why do Turbo bearings fail?
They fail because not enough engine oil is getting to the bearing to cool and lubricate it, and the reason for that is usually that the turbo bearing oil feed and oil return pipes are blocked with carbon from switching the engine off when the turbo is too hot. Could be that simply replacing these two pipes will fix it.
Why is my car whistling and hissing?
The charge air escapes, resulting in whistling and hissing. However, a stone chip in the charge air cooler will also manifest itself in this way. And the escaping boost pressure also reduces the vehicle’s power output. The exhaust gases leave the engine at a very high speed and several bars of pressure.
What does 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 does a turbocharger work?
A turbocharger is a turbine-driven forced induction machine that boosts the efficiency and power output of an internal combustion engine by bringing additional air into the combustion chamber. If it seems a bit complicated to understand how a turbo works, take the cue from the fact that an engine run by a mixture of fuel and air.
Why do diesel engines whistle?
Most Likely Issue. If you hear a high-pitched whistling sound from your Cummins engine, there’s a good chance it involves a boost leak. A boost leak happens when the clamps and other components leak out air when under pressure from the turbochargers.
Is engine whistling bad?
Whistling Hoses are crucial parts of your engine’s cooling system, but they are also the weakest. Constant circulation of air and cooling fluid through your car’s engine can cause small cracks in hoses, breaking their vacuum seal. The whistling sound you are hearing could be air escaping through these holes.
Why does my car whistle when I accelerate?
If the whistling sound in your car is most noticeable when you accelerate, the likely culprit is a vacuum leak. The system that controls the air flow between the mass air flow sensor and the engine pushes air through a hose. If the hose comes loose or is damaged it results in a whistling sound as air escapes.
How to fix a whistling car?
There are some quick ways to deal with a whistling car. Clean the streams of the alternator pulley. In conclusion, since the most common reason why the car is whistling is due to a worn-out serpentine belt, you should start by checking it and checking its tensioner roller.
Can a clogged fuel injector cause a whistling noise?
This might be surprising, but clogged fuel injectors can actually cause a whistling noise. Typically, the sound won’t be as loud or strong as most of the other causes in this guide, but there will be a number of other symptoms accompanying it. For example, the air-to-fuel ratio will be messed up and the check engine light will come on.
Why is my serpentine belt making a whistling noise?
The serpentine belt is a continuous belt that is used to drive multiple devices in your car’s engine, including the alternator and water pump. If the belt comes into contact with water, be it from driving through a puddle or from an interior fluid leak, it can start to make a whistling noise. The same applies if the belt becomes loose or damaged.
Does a turbo make a noise?
As many fans of a turbocharged engine will know, a turbo often makes a whistling sound. This whistle is the sound of the turbo operating effectively, also known as ‘spooling up’.
What does a blown Turbo sound like?
Whining Engine The turbo actually makes the engine quieter because it muffles the sound of the air intake. Then if you hear some noise which is louder than usual from the engine, which is a bit like a dentist’s drill or police siren, the chance you have blown turbo symptoms is 100%.
Why does my Turbo make a PSSSH sound?
The blow off valve will make a “psssh” sound, only louder. This is the sound of air harmlessly escaping your turbo. 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.
Is your Turbo failing?
Similarly, a turbocharged car that struggles to maintain high speeds or isn’t able to reach speeds it once could may be experiencing turbo failure. One of the unexpected advantages of a turbocharger is that it actually makes the engine quieter because it muffles the sound of air intake.
Is turbo flutter bad?
Turbo Flutter is Harmless In short, flutter is the sound of a turbocharger trying to push air. However, failing due to closed throttle. Therefore, it dramatically increases the load on the bearings of the turbo. If it occurs at higher engine loads or boost levels, it can cause premature wear to your turbo.
What does an unhealthy 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.
Why does my Turbo make a bad noise?
A turbocharger will make good and bad noises but with regards to the bad noise, it is best described as a police siren. Once your turbo has reached this stage, you should really be looking for a replacement. The police siren noise is usually caused by damaged turbines or missing blades.
How do you know if a turbocharger is bad?
The most common symptoms of a bad turbocharger are low engine performance, blue smoke from the exhaust, and a burning oil smell. You may also notice reduced fuel economy and a check engine light on your car’s dashboard. Here is a more detailed list of the signs of a bad or failing turbocharger to look for: 1. Power Reduction

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.
What are the symptoms of a failing turbocharger?
There are a variety of symptoms that are commonly associated with turbocharger failure in cars. Carefully analysing the performance of the vehicle while you are driving helps to spot irregularities and diagnose turbo issues by your self. One of the most significant symptoms of a failing turbo you should notice is lack of overall power.
How do I know if my car has a turbo?
Naturally you’ll become very aware of its performance and capabilities. If you notice that the vehicle is taking longer to get to speed and can’t dance between the traffic like it used to, then checking the turbo should be your first port of call.
How do I know if my engine is failing?
Never ignore your engine warning lights – have a competent mechanic examine your engine to diagnose the fault properly, as soon as you can, as leaving it will only cause further damage to your engine. Sometimes, you can hear when a turbo is failing – listen out for a distinctive noise when your turbo kicks in at around 1000-1500 rpm.
Do superchargers make noise?
This type of supercharger runs at a multiple (perhaps 3–5 times) the engine RPM, driven by a belt. This is around 16,000 RPM, but of course it varies with engine speed. They generally have 5–6 lobes, so the main noise (whine) is 15–30 times the engine RPM, or around 1,000–2,000 Hz.
Why does a supercharger sound so loud?
Here are some factors that may go into making a supercharger sound the way it does: Because the whine comes from the gears as they mesh, changing up the shape of the gears will change the whine. If the teeth have a very shallow angle, the whine will be louder. Others postulate that the noise comes from the rotors chopping the air.
Do turbochargers make noise?
While it is arguable that turbochargers reduce the sound produced by engines, because they muffle the sound of air intake to the engines making the engines somewhat quieter, it would be accurate to say that noises would still be produced. The noise generated by turbochargers is called a turbo whistle.
How do you make a supercharger whine?
Make sure that your throttle is opened — it’ll make the noise sound much louder, which will definitely help produce that supercharger whine. Having the perfect car is about way more than just how fast it goes, though that can certainly help!
How do superchargers work?
Twin-screw superchargers cost the most, but they can also sound the loudest. They operate by sucking their air through a couple of gears (resembling worm gears) and then compressing the air inside a rotor housing. Because the rotors are tapered conically, the air pocket gets smaller and denser the further into the rotor it goes.
Why is my turbo whooshing?
The whoosh noise, also called surge noise, is caused by the compressor working at or near surge conditions. Whoosh noise is a broad frequency band flow noise typically found during throttle tip-in conditions, but sometimes found even at steady state driving conditions.
Why is my turbo lag so bad?
Until that happens, the turbo does not play a role in boosting the car. This issue, usually called turbo lag, is when the turbo spools air and fuel to send into the cylinder. If this process is slower than usual, you are experiencing a boost leak. The concept is simple; due to a leak, it takes more time for a turbo to fill up the boost pipes.
What happens if a turbo is leaking?
Loss of Power While you are accelerating, the turbo builds pressure in the boost pipes to give the car higher performance. If there is a boost leak, it will take longer to fill these pipes with pressure, and the pressure will be lower than usual. This will cause a drastic loss of power in your car engine.
Why is my turbo blowing?
Anytime a turbocharger ingests something — be it dirt, dust, a shop rag or a bolt left in the intake — it can spell disaster. Unfortunately, outside debris making its way across the blades of a compressor wheel (the intake side) accounts for 80 percent of all turbo failures.
What causes a turbocharger to over speed?
As a result, the turbo has to work harder to increase air pressure. This problem is also known as over-speeding. Ultimately, it will reduce the efficiency and the boost delivered by the turbo. A turbocharger is essentially made of two fundamental components: the compressor at the front and the turbine at the back.
How do I know if my Turbo is blown?
One common sign of a blown turbo is smoke coming from under the hood or from the exhaust. But excessive smoke can also be caused by a myriad of other issues. How can you tell whether it’s caused by your turbo or something else? Pinpointing the exact cause of a smoking engine or exhaust isn’t easy, but it’s far from impossible.
Why is my journal bearing turbo blowing oil?
Having and Oil Restrictor in a Journal Bearing Turbo can Causes Turbos to Eventually to Blow oil, Because it Starves the Turbo Of Oil, Which Causes the Internals of the Turbo to Wear out (including the Seals). Don’t Use a Restrictor with a Journal Bearing Turbo, if You think the OIl pressure is “Too High” Then a Drain with a Larger Inside Diameter.
Why is my Turbo leaking oil?
Under the Circumstances Where the Turbo Is Leaking Oil, You are also Losing Oil Pressure. It is Very Common for the Engine to Spin Bearings, or lose Compression Due To Lack of Oil Pressure in the Engine, Due to Your Turbo Leaking all the Oil pressure out the Turbo Seals.
Why does my car make a whistling noise when accelerating?
Whistling noises that occur when accelerating a vehicle are often due to vacuum leaks under the hood. If a vacuum leak is the cause, the car is likely to make the same noise upon pressing the accelerator when the vehicle is idling. An automobile relies on constant vacuum pressure to operate correctly, according to 2CarPros.com.
Why do my windows whistle when I accelerate?
If the whistling is coming from your windows and gets worse when you accelerate, this is probably due to worn out window seals. Constant exposure to heat and cold can speed up the deterioration of the sealant. Fortunately, it’s cheap and quick to replace it yourself.
Why does my car make a noise when idling?
If a vacuum leak is the cause, the car is likely to make the same noise upon pressing the accelerator when the vehicle is idling. An automobile relies on constant vacuum pressure to operate correctly, according to 2CarPros.com. The engine uses a series of hoses and gaskets to maintain the vacuum.
Why does my catalytic converter make a whistling sound?
When this hose becomes loose or gets damaged, a whistling sound occurs when the air escapes. When a vacuum leak is present, you’ll notice the car running less efficiently. Your fuel economy rating is likely taking a dive during this fault. This repair isn’t necessarily urgent, but it could end up ruining your catalytic converter. 2. Boost Pipe Leak
How do you make a turbo flutter?
An absence of a blow-off valve, and sealing the opening where it was will create backpressure. This will make the turbo flutter.
How do I get a turbo flutter?
In summary to get turbo flutter is simply done by unplugging the recirc valve and having a means to enjoy the turbo flutter or chatter but then be able to put it back to stock and not have a fault code on your dash.
What is the difference between turbo flutter and a wastegate?
While both these components perform valuable functions, the sound they create doesn’t do a thing. Turbo flutter works the same way; the turbo is extremely valuable, but the sound or the “flutter” doesn’t do anything. The only difference is that while the wastegate and blow-off valve are supposed to make their sounds, a turbo isn’t.
Is turbo flutter harmful?
Experts describe turbo flutter as harmful to the engine and suggest that it may be avoided in some situations. Because of this, the load that is placed on the bearings of the turbo significantly rises. If the engine is under a heavier load or the boost level is greater, it might cause early wear on your turbo.
Why do turbos sound like they spool up?
This is why turbos sound the way they do when they spool up. Turbos usually spin at forty thousand RPMs on idle, but with the accelerator pressed fully, the engine is working much harder and produces much more exhaust, which drives the turbo harder and at higher RPMs.
How does a turbo work?
A turbo works by forcing more air into the engine, with the amount of fuel being injected in increasing correspondingly, increasing the strength of the combustion, and producing more power.
A turbo provides extra power because it uses the exhaust gases to pump air into the engine block under pressure. This technique is very effective and beside more power a turbo can decrease the fuel consumption. A turbo uses the exhaust gases to set a flywheel in motion, the more revs, the more exhaust gases the faster the flywheel turns.
What is a turbo system?
A turbo system is a part of your engine designed to use your emissions in the best way possible. Generally, combustion engines work by mixing air and fuel together, burning it, and using that to create small explosions in your pistons ( like with a carburettor or injection ).
Does a diesel engine have a turbocharger?
The oil cooling system takes care of the turbo and does not let it become overheated. Almost all the modern cars with diesel-run engines have turbochargers because diesel engines are tougher than petrol units and have simpler intakes. How Does a Turbocharger Work? (At a Glance)
Do turbos increase power?
As well as increasing power, turbos increase torque – an engine’s strength – particularly at low revs. That’s useful in small petrol engines which tend to produce not much torque at high revs without a turbo. Naturally-aspirated diesel engines, by contrast, produce a lot of torque at low revs.
Why do turbo cars sound different?
Essentially, the noise is caused by what is known as “reversion”. When a turbocharged vehicle builds up boost, and the driver backs off the throttle, the throttle body snaps shut, but the turbo is still spinning, trying to compress air.
Do aftermarket turbos make a fluttering noise?
On many cars that have aftermarket Turbo installed they produce the flutter noise almost every time they release the throttle. And I mean a lot of after market Turbos make this noise, do these people know it causes extra wear? yes but normally these cars arent driven daily, but instead for drag or race applications.
How does a car sound?
A car’s engine under load plays a range of frequencies, but its root note—the pitch its musical chord is built on—is defined by its so-called dominant frequency. These sound-generating vibrations derive from the combustion in each cylinder and the corresponding pressure waves in the intake and exhaust systems.
