What do turbos 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!

Do turbocharged engines make noise?

Usually a turbocharger muffles the sound an engine make, but these turbo cars sound utterly fantastic.

Do Turbos have different sounds?

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.

What does turbo chatter sound like?

When people think of turbocharged cars, one of the first things that comes to mind is the sound of turbo flutter, that fluttering/chattering sound which happens when the driver backs off the throttle in a hurry, such as when changing gear.

Why do turbos make that sound?

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.

Turbo Noises || EXPLAINED

Should I hear my turbo?

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.

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.

What does turbo flutter sound like?

The sound of air escaping the blow off valve has been described as turbo flutter by some, but is different in a few key ways. The first is the actual sound. The blow off valve will make a “psssh” sound, only louder. This is the sound of air harmlessly escaping your turbo.

What is a flutter noise?

Irregularities that occur at higher frequencies are called flutter and cause a roughening of the tone: a piano sounds like a harp, and voices waver with small, rapid variations above and below proper pitch.

Is turbo whistle a problem?

A "turbo whistle" usually indicates a worn and failing turbo bearing, which is pretty much all there is to go wrong with a turbo.

Why do some turbos flutter?

The air has to travel somewhere, so it heads back through the turbocharger. The fluttering you hear is the air escaping back through the turbo as the compressor wheel fights this motion.

Do turbos make car quieter?

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.

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.

Does a turbo act as a muffler?

TIL that under Texas transportation law, a turbocharger can count as a muffler for a diesel engine : r/cars.

What makes a turbo surge?

Whenever the breakdown of gas flow takes place in the turbocharger, a reversal of scavenging air occurs through diffuser and impeller blades into the blower side which causes surging.

What does a dump valve sound like?

Aftermarket Dump Valves typically vent the pressurised air into the atmosphere for the purpose of making noise, and are characterised by the 'standard trumpet' sounds.

What makes a car go Stustustu?

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 does my turbo sound like a siren?

A faulty turbo may result in a loud, siren sound coming from the engine. The louder the sound, the worse the problem could be. Here's the siren noise that typically results from a failing turbo. If you hear this noise, you should consult your mechanic as soon as possible to get your vehicle checked.

Do car 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.

What makes Stututu sound in car?

When there is vacuum (no boost) in the intake manifold relative to the rest of the intake system, the BOV opens. It's the BOV that makes the signature turbo sound ("pssst"; "sutututu"), not the wastegate.

Do turbos muffle sound?

There is little question that turbocharging an engine carries with it performance and fuel-economy benefits. Most also agree, however, that turbos have a knack for muffling engine noise, lowering the tone of the exhaust note, and layering on whooshing sounds.

How do I make my exhaust backfire?

Keep your foot on the pedal for a little bit. For me, it works after about 30 seconds of keeping the car off with the pedal down. Fire up your car while you stomp your foot on the gas pedal until it goes all the way down and then 'hold it there. ' Voila, you just backfired your car.

Why do V8 engines sound good?

The rich roars of the V8 are music to many people's ears. A V8 engine has two rows of four cylinders arranged in a V shape, and – in the cross-plane crankshaft type, rather than a flat-plane – these cylinders fire in an irregular pattern across the two rows.
