How to Use a Turbo Timer
If you own a turbocharged car, installing and learning how to use a turbo timer will help your turbo last for many years to come, with less chance of it failing. A turbo timer is a device that is wired to the car's ignition system and that keeps the motor running for a short period after the ignition is turned off. Keeping the motor running allows the turbo to cool down. The turbo is cooled by the engine's oil supply and when the oil is cut off abruptly, the turbo can overheat, potentially damaging it.
