It has factory turbo timer. It will keep fans and stuff running for few minutes after hard driving even if you turn off the engine and lock the door.

I was at the track last week. After a 20 minute session & cool down lap.. When I shut off the car, the fans still ran for a good 10 minutes. Yup, no timer needed.

There is a water pump that runs after you turn the car off that circulates water to cool the turbo. This runs even if the fans are not operational. You can hear a faint noise from the engine bay everytime you stop the car if you listen carefully. The auxillary fans only come on if the water temp gets too hot

I suspect the purpose of this is more for safety reasons rather than anything else ie it is to try and reduce radiant heat from the turbo and prevent the car catching fire, the hood or rocker cover getting heat damaged etc rather than trying to cool the oil etc BMW had issues on the R56 mini model (turbo) where the water pump that cools the turbo was failing. As a result there were quite a few cars that caught fire and even burnt to the ground. This resulted in a model recall and they replaced the turbo water pumps on these cars. |

As for turbo timer? No way I would do it. Imaging how it would mess with the complicated electronics / ecu in this car. IMHO it is not necessary, far better to be patient and simply just let the car run for a few minutes when necessary. |
