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.
Do turbos change exhaust sound?
The turbo has a similar effect on exhaust systems, where the exhaust-side impeller disrupts the exhaust flow by creating an extra gate for the sound to have to flow through. … The turbo also tends to make the exhaust quieter as a byproduct.
Are turbo engines more noisy?
As a general rule, turbo charged vehicles are somewhat less loud than a naturally aspirated engine. This is because the turbo acts as a muffler since it is in the exhaust system. This combined with a muffler will significantly change engine tone and noise, but not necessarily reduce exhaust noise.
Does turbo reduce sound?
The turbocharger intercepts the hot pulsing exhaust gases and extracts energy from them to power the compressor. this obviously changes the sound of the exhaust, making it much quieter and smoother.
Does a turbocharger affect the sound of car?
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.
Why do turbo cars sound so good?
Unlike turbocharged cars, the supercharger in a supercharged car is powered by a belt that’s driven by the engine. So, the exhaust gases can be sent straight towards the exhaust, where they get turned into wonderful-sounding notes.
Does a turbo act as a muffler?
The turbo will act as a second muffler, so in theory it should be plenty quieter. I would keep your current exhaust and see how that sounds first before you spend money on a new exhaust, it may surprise you how much quieter it will be, especially at cruise.
Why do some turbos sound different?
Those sounds are from compressor surge. The bigger the compressor the more prone it is to doing it and having too small a blow off valve can cause it too but that is not the only possible cause. Diesels almost always do it if the boost is turned up.
Do turbo cars have exhaust?
The turbo is powered by the exhaust gases. One side of the turbo is located at the exhaust manifold, the other at the engine’s air intake, and it contains two small fans joined by a shaft. As exhaust passes through the turbo, it spins one fan, called the turbine.
Why do turbo cars backfire?
The reason for backfiring being common on a turbo vehicle is the fact that for all that extra air a turbo pushes into the engine it must also get more fuel. When your foot lets off the gas there is more raw unburnt fuel coming out of the cylinder head and flash igniting which causes the sound of a backfire.
Do naturally aspirated engines sound better?
Larger displacement engines sound better, they deliver power in a more linear fashion which some people prefer, and having no turbine in the way of the exhaust means a naturally aspirated engine likely sounds better than a turbocharged engine of the same cylinder count/displacement.
Do NA engines sound better?
Smaller engines can be utilized, and exhaust gasses provide a way to spool turbos. … Noise – To this day, there is nothing better than the sound of a naturally aspirated performance engine. It’s generally louder and quite frankly sounds better. With the addition of individual throttle bodies, the sound gets even better.
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.
What does a blown 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.
