The turbo is predominantly water cooled, so it will continue to run coolant through even after the engine is shut off to cool it down. Save your money and petrol and dont bother with a turbo timer. Go buy a front lip or something.
They were for the older style oil cooled turbos, you had to leave the engine running to maintain oil flow to cool down the turbo.
