Some turbo cars will be fitted with a turbo timer, which keeps the engine running for a specified time after the ignition is turned off. This allows the turbo to cool down before the engine shuts off, which prevents potential damage to the turbo.

Do you let a car with turbo it idle after a run?

YES! Especially if you have been pushing it hard. Turbo's need to 'cool off' after being used, and is very important if they have been used hard. Oil from the engine will cool the turbo off after a few minutes. Sophisticated cars and cars with twin turbos usually have timers built in to the ignition system which will run the engine for 2-4 minutes after you turn the key off, specifically to cool the turbo(s). You should always idle a car with a turbo before you turn the engine off - longer period of time if it was racing.

Why does your fin in your turbo stop spinning on idle?

The TURBINE inside a turbo-charger stops spinning when the vehicle is at idle because there isn't enought exhaust pressure to keep it spinning, lowering the internal engine pressure. creating less wear on the turbo and engine also alowing the engine to idle.. if it was to continue forcing air into the engine it would also need to force gas. to match the air fuel ratio to keep the car from dying, causing the engine to rev.. not stay at idle..
