The symptoms of damage caused by excessive temperatures Loss of power and performance. A smoky exhaust. Abnormally loud whirring noises. A lack of boost, or your boost gauge showing a drop in pressure (if your vehicle is fitted with one)
- What happens if a turbocharger is too hot?
- Whilst turbochargers are built to withstand the high temperatures generated during normal operation, if the temperature of the exhaust gases is too high, then it can cause catastrophic damage.
- What can damage a turbo?
- Foreign objects – there’s a chance larger items of debris, such as stones or even broken car parts from other cars can get sucked into the turbo via the inlet. As you would expect, these particles can cause severe damage to the wheels and blades in the turbo. Check your air filter is serviced regularly.
- How do I know if my turbocharger is bad?
- This is a sign that something has gone wrong with the turbocharger. It might be time to make the upgrade to a new one. This will occur when the turbo housing develops a crack. This allows the oil to seep into the exhaust system. In return, that will cause irregular gases to be produced and emitted from the exhaust.
- Can you turn off the engine without damaging the Turbo?
- The turbocharger is very hot at this point. If you turn off the engine immediately, it could damage the turbo. Therefore, you need to let the unit cool off first. To avoid problems, you should let the vehicle idle for 30 seconds or so. Then, you can shut off the engine without causing any damage to the turbo.

Can water damage a turbo?
If water is not plumbed correctly, this intense heat can potentially destroy the bearing system and the oil-sealing piston ring behind the turbine wheel. Water ports are located on either side of the turbo’s center housing.
- Is it possible to damage a turbo at idle?
- Unfortunately, yes. The turbo is spinning at least 10,000 rpm even at idle. If it hits something like a paper towel or a signifigant amount of water, the turbo wheel usually touches the housing or the bearing gets ground up. Even if the damage isn’t immediate, it builds up since the turbo has to be balanced.
- What happens if a turbo wheel is damaged?
- If it hits something like a paper towel or a signifigant amount of water, the turbo wheel usually touches the housing or the bearing gets ground up. Even if the damage isn’t immediate, it builds up since the turbo has to be balanced. A damaged wheel will throw it out of balance and over time it will wobble until it finally snaps.
- Does water in a turbo cause coolant to leak?
- The water in a turbo allows you to safely shut the car off even after very recently boosting. The water mass absorbs the heat instead of the oil left in the CHRA having to do it so as not to get ‘oil coking’ damage to the shaft. Unless the casting is cracked then no, coolant won’t leak from there.
- What happens if water is not plumbed in a turbocharger?
- Heat stored in the turbine housing and exhaust manifold “soaks back” into the center section of the turbocharger after shutdown. If water is not plumbed correctly, this intense heat can potentially destroy the bearing system and the oil-sealing piston rings behind the turbine wheel. Does my turbo really need water? Why should I care?
Why are turbos so hot?
Turbo chargers get hot because hot exhaust gases flow through the manifold then the turbo. So when the turbo is red hot, the manifold also glows with red heat. The temperature of the exhaust gas in diesel engines varies by manufacturer.
- Why does a turbo need a hot exhaust gas?
- A turbo needs enough exhaust gas to overcome its boost threshold, which both throttle position and engine rpm impact. The hot exhaust gas heats the turbo raising the intake air temperature. Hot air has decreased density and less oxygen than cold air, which causes reduced engine performance.
- What happens to a turbocharger in hot weather?
- Again, this serves to increase the amount of work the turbo has to do, reducing the overall efficiency and performance of your vehicle’s engine. For most people, the drop in turbocharger performance during hot weather won’t be a problem.
- How does a turbo boost work?
- Adding boost with a turbo increases the temperature of the charge air above inlet air temperature through compression of the air. This calculator provides the temperature of the air as it exits the turbo. If you are using an intercooler we have a calculator that will work out the temperature after the IC as well.
- How does hot air affect engine performance?
- The hot exhaust gas heats the turbo raising the intake air temperature. Hot air has decreased density and less oxygen than cold air, which causes reduced engine performance. Before air enters the engine, it travels through an intercooler to lower the intake air temperature.
Can a turbo catch fire?
Irrespective of whether the turbochargers are heat shielded, the turbocharger’s surface temperature is hot enough to ignite fuel or oil when it comes into contact with it.
- Can a turbo charger cause a fire?
- While the fires occurring within the turbo charger are usually restrictive, some fires may spread to the air-intake side of the truck. Consequently, the fire may spread to the engine compartment of the truck. If the oil hose or the fuel line of the truck malfunctions, oil may get squirted into the exhaust or the turbo charger.
- Do you need an oil catch can on a turbo car?
- Now that we’ve explained why you’d need one, we can talk about what the catch can will actually DO. By installing an Oil Catch Can on your turbo car, you’re preventing those oil vapors from collecting on the inside of your intake manifold, helping you keep the need for media blasting intake cleaning spaced as far apart as possible.
- Can a torch cause a truck to catch fire?
- Even the heat from a simple torch can cause certain components of the truck to catch fire. Turbo charger oil seals may fail, thus causing the oil to spill into the exhaust. This may cause internal fires and a spike in the temperature.
- How do I prevent a turbocharger fire?
- Review your prevention, monitoring and contingency controls to ensure the risk from turbocharger fires is adequately controlled. Deflection barriers separating the oil hoses and fuel lines from an engine’s turbocharger Contain fuel lines and hydraulic hoses to prevent spray onto hot surfaces.
Why do turbos like cold air?
As air temperature increases, the density of the air, and the amount of oxygen it holds decreases. This means that the turbocharger has to work harder, spin faster and compress more air to produce the same amount of boost it would at lower temperatures.
- How do I cool my Turbo?
- Fit a larger air intake – increasing the amount of air available to your turbo Replace your air filter – to ensure that it is clean and free flowing Fit a water or methanol injection system – which can be used to cool either the intake air, or the charged air.
- How does a turbo work?
- A turbo provides extra power because it uses the exhaust gases to pump air into the engine block under pressure. This technique is very effective and beside more power a turbo can decrease the fuel consumption. A turbo uses the exhaust gases to set a flywheel in motion, the more revs, the more exhaust gases the faster the flywheel turns.
- How does hotter air affect the turbocharger?
- In addition, hotter air also has a secondary affect on the turbocharger, by naturally increasing the operating temperature inside the turbo. Usually, the intercooler works to cool the air from the hot air intake, but in warmer temperatures, the intercooler becomes less efficient, as it is also exposed to the warmer temperatures.
- Why does a turbo make a loud noise?
- Turbos tend to make the air escaping the engine a little muffled, due in part to the fact that there are other noises happening, but mainly because of the fact that the turbo itself acts as a muffling chamber. The result is that the engine doesn’t scream as loudly and many of the natural tones of the engine itself are lost.
Does turbo waste more gas?
A turbocharger typically helps a car get better gas mileage because a smaller engine can be used to get the same amount of performance. Expect a turbocharged engine to be about 8% -10% more fuel efficient that the same engine that is not turbo equipped.
- Can you use premium gas on a turbo engine?
- When you use premium gas on your turbo engine, it will provide more power compared to using regular gas. However, higher octane would not affect lower-compression engines. These engines will not completely burn the fuel leading to wasted gas. There will be no significant increase in performance when you use premium gas on a regular engine.
- Do turbocharged cars get better fuel economy?
- As I’ve learned through years of testing, turbocharged cars often return much worse fuel economy than their official ratings would lead you to expect. My findings parallel those of other testers. Consumer Reports, for example, concluded that downsized, turbocharged engines typically achieve worse mileage than larger engines without turbochargers.
- Can a turbo engine boost without a wastegate?
- But correct, in that without the larger mass of air that an engine without a wastegate will not see any boost (example of a non-wastegate equipped turbo engine is used in the Piper Turbo Arrow. The throttle is pushed forward a little at a time and the manifold pressure watched.
- Do turbo engines use high octane gas?
- Turbo engines are designed for use with high octane gas. These are suitable for cars with engines that operate at higher compression ratios, allowing them to completely consume the fuel’s energy. Turbocharged engines have high compression ratios since they are designed for high performance.
How hot can turbo get?
A turbocharger turbine lives in a terribly hostile environment. The turbine is driven by exhaust gasses that can exceed 1875°F (1025°C) and which are very corrosive.
- How hot does a turbocharger get?
- Manifolds, catalytic converters and exhaust pipes on some vehicles can reach 650 degrees C (11200 degrees F). Turbocharger system components using exhaust gas to compress intake air are often as hot or hotter than other exhaust system components.
- Why do turbos get hot?
- When you start to compress air, it gets hot. With turbos they have efficiency ranges, of how much air they can shift, and not start overheating the air. Once you start trying to run more boost than is suitable for the turbo, it’ll start to just turn into a heat pump.
- What causes excessive exhaust gas & turbo temperatures?
- Excessive exhaust gas and turbo temperatures have a number of different causes, including: Poor quality oil – that does not divert heat away from the turbo effectively enough, or carbonises because it cannot withstand the high temperatures generated by a turbocharged engine
- Does a Subaru Turbo heat up if you drive hard?
- Yes, you have to do that. Your turbo heats up to around 900 degrees Celsius under hard driving conditions. When you shut off the car, You suddenly take away the heat source and the ambient temperature falls to around 95 degrees Celsius (the normal operating temperature for a Subaru that has been driven hard).
Should I warm up my turbo car?
Warm up your engine As the engine temperature increases, so does oil temperature. This thins the oil, enabling it to run more freely and lubricate the moving parts of your engine.
- How long does it take a turbo to warm up?
- Stay out of boost while it’s warming up, depending on your climate that can be anywhere from 5 to 15 minutes. Really, all of this is true for naturally aspirated engines as well, turbos are just more sensitive to it. Cars don’t like to be run cold, but it turns out that the quickest way to warm up an engine is to drive it. Yep.
- What are the best tips for turbocharged cars?
- Professor Ricardo Martinez-Botas gives his thoughts on the five common tips for turbocharged cars. These apply mainly to cars older than 10 years, and modified cars. 1: Warm your car up before driving – let the engine run and bring the oil up to temperature. “Absolutely.
- Why is my Turbo so hot?
- Unless your last couple of miles were driven gingerly, the turbo will likely be hotter than ideal for shutting the engine off. The reason for this is because of that lifeblood-oil coursing through it. If it’s not given proper time to circulate and cool, the oil cooks into sludge—and clogs the oil channels.
- How do you cool down a turbo?
- After working your turbo out a bit (like on a spirited drive or a few hours of long highway driving), give it a bit of time to cool down before shutting off the engine. A minute or two of idling helps your oil cool the turbo (and itself). 4. Cool It Down
Can you overwork a turbo?
If the turbo continues to over speed, it can over boost the engine, resulting in serious damage to the internal components and potentially complete engine failure !
- Do you have a blown Turbo?
- If you think you might have a blown turbo, get it looked at as soon as possible by a qualified technician. The longer you leave it, the more damage it’ll cause, and the more expensive it’ll be to fix the problem. At Halfords Autocentres, we offer a Diagnostic Check for just £49.99.
- Do Turbos wear out over time?
- The car’s age and mileage. Although turbos are designed to last for the lifetime of the vehicle, it is possible for them to wear out over time. This might be down to the quality of the turbo originally fitted, or how hard you drive the car. Cracked or worn seals.
- How do you know if a turbo is bad?
- Blue and gray smoke can also be a sign of a damaged turbo. A sludged or coked bearing housing, a restricted oil drain line, or a broken oil seal is normally the guilty culprit, but other kinds of damage to the turbo can also result in blue smoke. Thin clear or white smoke is completely normal. This kind of smoke consists mainly of water vapor.
- What happens if a turbo overspeeds?
- If the turbo continues to overspeed, it can overboost the engine, resulting in serious damage to the internal components and potentially complete engine failure. BTN Turbo say overspeed can be caused by a restriction in the air intake filter or pipe work, or a split or detached air hose, allowing allowing incorrect amounts of air into the turbo.
Do I need to let my turbo cool down?
Turbocharged engines do need to cool down before they are turned off. But in nearly all driving conditions, the engine does not reach temperatures that require a deliberate cooling down period.
- Should I idle and cool down my turbocharged engine?
- You should idle and cool down your turbocharged engine because the oil in the bearing shaft can easily get burnt, and the residue can cause the turbo engine to fail. The other parts of the engine could also get damaged because the engine did not cool properly before the switch off.
- How do you keep a Turbo Cool?
- To keep them cool two methods are used, oil cooling and water cooling and sometimes both together, depending on tge size of the turbo and the thrust it generates. While you run the engine, the oil and coolent keep running through the engine and tge turbo.
- What temperature does a turbo cooled engine stay?
- So in a turbo charged engine, the engine will still remain around 80 degree Celsius (because it is constantly being cooled). How come the radiator/fan which cools the engine, can’t keep the turbo just as cool as well? Jul 22, 2015 at 12:19 The turbine side needs hot gases in order to make it spin really fast.
- How do I lubricate my turbo after hard driving?
- After hard driving, just drive your car slowly/calmly for a few miles. This will let the turbo cool down and because the engine is still on, the various turbo parts will still be lubricated whilst the turbo is cooling down. Not the answer you’re looking for?
