A turbo can make a few different noises. Firstly they rotate at pretty high speeds and tend to produce a fairly high pitched whine or whistle once they get up to speed. The blow-off valves which vent excess pressure can also make a noticeable hissing sound.
What does a faulty turbo sound like?
A loud whining noise – Often, a failing turbocharger will make a loud, distinctive noise when under boost – a bit like a dentist’s drill or police siren if compressor wheel damaged. If you start to hear this noise from your engine, it’s definitely time to have it checked out!
Why do turbo cars sound better?
Simply due to the turbo quieting the exhaust sound down. Turbocharged require a free flow exhaust in order to create maximum boost from exhaust flow. Running the exhaust through the impeller housing tends to remove the pulses, effectively muffling the sound.
What is the disadvantage of turbo engine?
Disadvantages of a Turbo Engine
Well, more power means more energy output per second. This means that you have to put more energy when you use it. So you must burn more fuel. In theory, that means an engine with a turbocharger is no more fuel efficient than one without.
How do you know if your turbo is blown?
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.
Can you still drive a car if the turbo goes out?
Unless your turbo disintegrates on the inlet size, no problem. If the turbo damaged the cylinders/pistons, you would know it, the car would not be able to drive or make awful noises. Regarding power, if you have enough, you have enough. Of course with turbo, you would have more and your mpg would be better.
Why do turbos whine?
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.
Should a turbo whistle?
When should you be concerned? 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 turbo flutter good or bad?
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.
