What does a noisy turbo mean?

If the turbocharger gets too little air, it will start making noises. If, for example, the air filter is not checked thoroughly and replaced regularly, the intake resistance increases substantially.

What does a healthy turbo sound like?

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 an unhealthy turbo sound like?

Is loud turbo whistle bad?

How do I know if my turbo is OK?

How long do turbos last?

Ideally, your turbocharger should last roughly the same time as your vehicle. Specifically, most turbochargers need replacement between 100,000 to 150,000 miles. If you stay on top of car maintenance and scheduled oil changes, your turbocharger can potentially last beyond that.

What makes the stututu sound?

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.

What are normal turbo speeds?

The turbine in the turbocharger usually spins at speeds between 80,000 and 200,000 rotations per minute (rpm) — that's up to 30 times faster than most car engines can go. And since it is hooked up to the exhaust, the turbine also runs at very high temperatures.

What are the first signs of turbo failure?

Loss of power – perhaps your turbocharged vehicle isn't exerting as much power as usual? If it's showing a slower acceleration – or can't reach expected speeds – this could be an indication of a problem. Unusual noises – a loud whining noise may be heard from your engine if your turbo has a fault.

What does a blown turbo feel like?

The most common signs of a blown turbo are:

The acceleration of your car seems slow and noisy. Your car doesn't maintain high speeds easily. There's smoke coming from the exhaust. There's an engine fault light on the dashboard.

Can a blown turbo damage an engine?

Ignoring blown turbo symptoms can cause further damage to the car's engine. The more you drive your car with a blown turbo, the more damage the engine will have and therefore will cost more to repair.

How often do turbos need to be replaced?

Most turbochargers need to be replaced between 100,000 and 150,000 miles. If you are good at maintaining your car and get timely oil changes your turbocharger may last even longer than that.

Can over revving damage turbo?

Pushing the turbo to ever higher speeds, especially when making modifications to the engine, will take it beyond normal operating speeds and can cause damage. Components will be stressed more than the manufacturer originally intended and the components will fail over time.

How much is it to replace a turbo?

The average cost for a Turbocharger Assembly Replacement is between $1,949 and $2,251. Labor costs are estimated between $497 and $627 while parts are priced between $1,452 and $1,624.

Why is my turbo fluttering so much?

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.

Why do turbo engines pop?

These last efforts of adding fuel and dropping spark will place unburned fuel in the exhaust which will ignite in the pipes causing the violent popping sounds.

What is the sound of turbo blowing?

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.

What kills a turbo?

Extreme exhaust heat is what powers the turbine side of the turbocharger, and over time, 2000° temps will take a toll. Prolonged exposure to that kind of heat will eventually kill anything, guaranteed.

Is a 4 cylinder turbo better than a V6?

Modern turbocharged four-cylinder engines, when engineered properly, will either beat or match a naturally aspirated V6 in almost every category. Turbo-fours are lighter, more efficient, and can be more powerful than a naturally aspirated V6. The only thing that a V6 will always do better is towing capacity.

At what RPM do turbos kick in?

A decent turbo hits full boost at 3k rpm, but it varies depending on the mechanical efficiency of the turbo and how much exhaust is being put out.

Can I drive with a bad turbo?

Can I drive my car with a damaged or blown turbo? The short answer is that you can still drive your car with a blown or damaged turbo. However, the longer you drive it in this state, the more damage the engine will have and the more expensive repair bill you will get.

What is the most common turbo failure?

Most failures are caused by the three 'turbo killers' of oil starvation, oil contamination and foreign object damage. More than 90% of turbocharger failures are caused oil related either by oil starvation or oil contamination. Blocked or leaking pipes or lack of priming on fitting usually causes oil starvation.

What should you not do with a turbo engine?
