I have two turbo cars. If I run them hard, put it in park and finsish listening to the song on the radio then turn the motor off.
None. End of thread.How long should I wait for the cooldown when I idle before shut off?
answer depends on if the turbo is water cooled or air cooled and how nard the engine has been working prior to shutdown.How long should I wait for the cooldown when I idle before shut off?
Yeah that's gasoline engines for you. The exhaust runs way hotter at idle than diesels so you don't ever really cool them down by idling them.No, not always. There is a guy who rebuilds Mini Cooper turbos and he said he gets a high # of them with coked turbo shafts, some really bad ones. They are water cooled and I can assume the extreme Mini's, the owner's know how to babysit their turbos. Yet he still gets coked turbos in on a regular basis he said. He is an advocate of cooling down "pushed" turbos.
The auto industry is flush with those.Honestly, if that's not enough, then it was a bad design to begin with.
Ditto with the 2.7 eco. It’s about the size of a liquid cpu cooler pump, 1” thick by 2.5” circle, plumbed inline with the hoses, supported by the hoses. its not big, but it doesn’t have to be.On vehicles with the 4-cyl Ecoboost 1.5, it has an electric water pump plumbed into the coolant circuit that covers the turbo and air-to-water intercooler that is bolted to the intake. After shutdown, the electric pump continues to run for an addtional 5 minutes. Just for reference, the 3-cyl Ecoboost motors in the Bronco Sport and Escape are air-to-air.
