How to provide additional pumped cooling for your Turbo, like more modern cars. I have seen burnt out bearings in a Turbo that then generated loads of oily smoke. I have also heard the water boiling in the Turbo after stopping.
To stop that and prevent the oil in the Turbo from cooking and coking up the bearing, some modern cars have an additional electric water pump that runs on after the car has stopped, that cools the turbo. You may have heard the advice to idle the engine for a few minutes after stopping to allow the Turbo to cool down. Well this circuit does that for you, but without having to leave the engine running. It is a run-on timer with extra water pump. Importantly the timer circuit is set up to use ZERO power after the time of 4 minutes is up, so as not to drain the battery.
In this video I show how I added a cheap second hand eBay water pump, meant for this purpose, to a turbo used in a Freelander 1.8 Turbo. Equally applicable to MGZT turbo, MG6 Turbo and lots of other turbo cars both petrol and diesel that don't have pumped water cooling that still runs when the engine has stopped.
