What causes a turbo to make noise?
Potential causes of turbo noise include: • Boost/air/vacuum leak – either on your engine intake, or your intercooler • Compressor wheel damage
Can you make a turbo sound without a turbo?
However, if you do not own a turbo car, you can achieve the blow off valve noise via an electronic system, which creates a fake turbo noise. Some car owners even opt for an exhaust turbo whistle that attaches to the end of your exhaust tips.
How does a turbocharger work?
A turbocharger makes use of the used exhaust gases and forces it through the turbo that acts as an air compressor. The additional air produced from the turbo gets pushed into the cylinder that allows for more fuel to be burnt. A turbo in a car is one method to increase car horsepower and overall efficiency.
What are the common problems with turbocharged cars?
Turbos are a great way to improve the performance of yours car, however there are many common turbo problems that you should be wary off before buying a turbocharged car. Loud Siren Noise. Turbocharged cars do make good noises such as spooling or a blow off valve noise but there are also bad noises. Poor Acceleration.
Why are turbo cars quieter?
If you recall, turbochargers are powered by an engine's exhaust gases. Exhaust gases that would otherwise have been sent down the pipes are used to spool turbochargers' turbines. When you take away a portion of the exhaust gases, there's naturally less to send into the exhaust system.
Does a turbo reduce noise?
Much like the effect on the intake, this results in a flatter, more sinusoidal tone to the exhaust, which most people would say is less exciting than an NA engine of similar design. The turbo also tends to make the exhaust quieter as a byproduct.
Do all turbos make noise?
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.
Does turbo engine make more noise?
One of the unexpected advantages of a turbocharger is that it actually makes the engine quieter because it muffles the sound of air intake. However, if you start to hear a loud, whining noise - a bit like a dentist's drill or police siren - it's a potential symptom of turbo failure.
Do all turbos flutter?
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.

What noise should a turbo make?
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'.
Why do turbo cars backfire?
The reason for the exhaust backfiring is essentially the same reason why the normally aspirated engines perform a similar dance. Turbochargers take time to spin or spool up to their normal speed to create boost. These turbo shaft speeds are incredibly fast — anywhere from 60,000 to 250,000 rpm and higher.
Why do some turbos sound different?
This could mean one of two things, either your wastegate or blow-off valve isn't releasing a sufficient amount of pressure or you are running too much boost on the stock turbo. Tuning down the boost or fitting a higher pressure BOV can remedy the situation and return the 'whoosh' sound.
Why do turbos whistle?
However, one of the important issues to take into account when a turbocharger is used in passenger cars is the whistling noise due to unbalanced forces that can be perceived by the driver, which causes discomfort.
What can cause carbon deposits in a turbocharger?
Lack of oil changes can result in a build up of carbon deposits entering the turbocharger. Objects Entering the Turbo. Dust, stones, leaves and other small objects can enter into the turbo via the compressor or turbine inlets.
Why does my turbo make a siren sound?
The police siren noise is usually caused by damaged turbines or missing blades.
What are the symptoms of a bad turbo?
Loud Siren Noise. Turbocharged cars do make good noises such as spooling or a blow off valve noise but there are also bad noises.
What happens if your turbo breaks?
If you have diagnosed that your turbo has broken, you will be thrown into the whether you should invest in a new or reconditioned turbo. Both will fix the car and be backed up with warranties in case the turbo breaks again, but whats the best solution?
What is turbocharger?
A turbocharger makes use of the used exhaust gases and forces it through the turbo that acts as an air compressor. The additional air produced from the turbo gets pushed into the cylinder that allows for more fuel to be burnt.
Why does my turbo fail?
Below are some of the main reasons for turbos to fail: Cracks and Poor Seals. A turbo uses forced gases to push back into the cylinders and if there is a crack or faulty seal, some of that gas will be lost. Pipes leading to the turbo often crack overtime and is fairly common (see below photo). Old Age or Heavy Use.
How to tell if your turbo is leaking oil?
Increased Oil Consumption. If you are noticing your car using more oil , this could be a sign that your turbo is leaking oil and leaking into the manifold. Engine Management Light.
How does a turbocharger work?
It does this by using the energy in wasted exhaust gas (on the turbine side) to spin a turbine wheel, which then (on the compressor side) pulls cold, fresh air in and pressurizes it for our engine to consume. The more air we put into our engine, the more power it can produce.
What is turbo smart?
All Turbosmart BOVs are designed with maximum air flow in mind for performance and turbocharger reliability. They are designed with a unique Boost Balance system which means they cannot be overcome by increased boost levels, they use light pistons to ensure quick response to eliminate surge, and then promote boost and throttle response equally by closing fast, ensuring turbocharger momentum is maintained, reducing lag and improving acceleration.
What is the problem with a turbocharger?
The most common issue associated with excess heat and turbochargers is housing damage.
How can turbochargers be mitigated?
At the end of the day, many of the issues that arise with turbochargers can be mitigated by working within the specifications provided by the manufacturer and ensuring that the turbo is getting proper lubrication in a contaminant-free environment.
How does forced induction work?
By forcing more air into the combustion chamber, an engine can function more efficiently and in turn provide more power. Either supercharging or turbocharging can provide this benefit to an engine; superchargers are belt-driven and are therefore operating whenever the engine is running, while a turbocharger is driven by the exhaust gases that the engine generates as it builds revs throughout the powerband.
Can debris damage a turbocharger?
This isn’t so much an issue of debris from the outside world mingling with the workings of the turbocharger, though.
Does a turbocharger have parasitic loss?
The turbocharger does not have the same parasitic loss a supercharger does, and for that reason, turbocharging has become an increasingly popular choice for OEMs looking to improve power output, fuel economy, and emissions over similarly powerful, larger-displacement naturally-aspirated or supercharged engines.
