Why turbocharged engine should not be stopped at high rpm?

You must understand that turbocharged engines run by exhaust gases. The hot gases and high spinning speed makes it extremely hot after a drive. High temperature causes the engine oil to burn and lose its properties.

Why should a turbocharged engine not be switched off immediately and left on idle for a while before shut 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. The layer of oil around the turbocharger bearings stop flowing and literally gets “burnt”.

How long should you wait to turn off a turbo car?

When you drive it gently around town, 15 seconds should be more than adequate. When you drive the car hard ie. when your husband drives it, you should let it cool for 30 to 60 seconds.

Why is it advisable to allow a turbocharger to idle after a high speed run?

It helps cool down your turbo by keeping your engine idling for a preset amount of time (after you turn off the car).

Should you let turbo cars idle?

Drive your car gently for the last minute or two of the drive, or let the car idle afterwards for at least 60 seconds. By letting it run. the oil will continue to circulate and cool down the turbo. Boost leaks can cause your turbo to overspin, which leads to failure.

Is it bad to let a turbo car idle?

Drive your car gently for the last minute or two of the drive, or let the car idle afterwards for at least 60 seconds. By letting it run. the oil will continue to circulate and cool down the turbo. Excessive boost pressure can cause heavy, damaging surge or overspin the turbocharger at the top end of the RPM band.

Should you let a turbo car warm up?

Yes, turbo chargers in themselves need to be warmed up before driving and cooled down after driving. This is to save the bearings in the turbo assembly from deforming. Turbo chargers function at very high rpms, mostly in excess of 100k rpm. As a result, oil temperatures are quite high.

Does a turbo decrease engine life?

Turbos Reduce the Lifespan of an Engine One of the most common turbo myths is that running boost will damage your engine over time. However, a properly implemented turbo pushing enough PSI through a motor to produce respectable levels of power won’t strain a motor any more than idling in traffic will.

Should you let a turbo warm up?

Should you let your car idle after driving?

No. It’s completely unnecessary after a long or short drive. Normal driving conditions are so mild compared to what the engine can endure that there is no reason to randomly idle the engine following a drive. All you will do is burn fuel and create pollution.
