Idling the engine cools the turbo because it circulates the oil, yet does not make the turbo "work." The amount of cooling it needs is directly related to the way you just finished driving it. When you drive it gently around town, 15 seconds should be more than adequate. When you drive the car hard ie.

Why do you need to let a turbo cool down?

Switching off when the engine is very hot stops the circulation of oil. The layer of oil around the turbocharger bearings stop flowing and literally gets “burnt”. The black sludge that forms is similar to what you find on a burnt frying pan. That is not good for any engine.

Do you have to let a turbo engine warm up?

Cool down

Just as you need to warm up your engine, you need to let it cool down. Extended journeys and high speed driving creates a lot of heat in your turbocharger, and if you turn off the engine whilst it's still hot, you can cook the oil inside, leading to unnecessary build up of carbonised oil inside your turbo.

What happens if you don't let turbo cool down?

As they say, you need to let the turbo spool down as it spins excess of 100,000 RPM while doing this oil is used to lubricate it, if you shut it down immediately there are high chances of oil residue forming on the turbo lines and clogging it up.

Why engine fitted with turbocharger should be left to idle before stopping?

To let the turbo cool out, this helps to add longevity to the lubricating oil from the excess exhaust heat. By letting the oil flow through the torbo it moves heat away from the bearings and prevents the oil from just sitting and burning onto and gumming up the shaft and bearings.

Is there a break in period for new turbos?

Allow the vehicle to idle for 10-15 minutes without applying any throttle. Even at idle, the turbo can be spinning at as much as 28,000 RPM's on certain models. Use this time to check for any loose fittings, hoses, exhaust leaks, and to bleed the cooling system of any trapped 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.

Do turbo engines need to idle before turning off?

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.

The turbo are always spinning when the engine is running, and will even spin down for for up to a couple of minutes after you shut the engine off.

At what rpm is turbo activated?

While your car's engine revs, at cruise, at around 2,000 rpm, a turbo's turbine can reach rotational speeds of more than 280,000 rpm.

Does a new turbo need running in?

Installing a new turbo. Before removing the turbo, we advise you let the engine idle to operating temperature before switching off and draining the engine oil from the sump (be VERY careful as oil will be HOT). As the oil is more fluid when warm, you have a greater chance of removing as much as possible.

Why does my turbo whine?

3 – 5 minutes. This will allow time for the oil to cool down the turbocharger while the engine idles down. If you were to rev up your engine and then shut it off, it will cause damage and wear to the turbocharger as the oil pressure drops with it is still spinning at very high RPMs.

How long will turbo last?
