Turbo Cool Off

[Coderedpl]

Just a silly thought that's going through my mind, how many of you actually sit there after you get to your destination and let it "cool off/down"?

I've honestly done this since I had my A4, and even got into a habit of doing it with my naturally aspirated S4 =O
The golf r is no different, i let it warm up till the rpm's drop and let it cool off for a minute or two, if i drove it really hard then I let it cool off for much longer.

I've heard some people saying this is un-necessary but I assume that's a false statement.

so do you?

I've been driving it easy before getting to my destination, I think having air moving over the radiator, etc., is probably a better way of getting it to cool down. So no, I haven't been letting it idle when I get to where I want to be.

I have over 224,000 Miles on original engine and turbo. I don't wait for turbo to cool off while idling. I just take it easy the last couple miles of my trip.

These engines have an electric water pump to help cool the turbo and engine down once the engine is turned off.

But another good practice it to just take it easy for the last <1minute of your trip before you park the car - in reality, you are normally coasting in a carpark looking for a parking spot or similar anyway for 30 seconds - so you are safe to just turn it off.

A freind of mine lets his car idle for about 10 mins after driving which is both totally unnecessary and actually counter productive as heat soak settles in - he would be better off to just turn the car off after 30 seconds.

That's my thought process as well. Airflow is the most important, but after that, idle sucks.

Just don't shut it off after immediately running high revs. When you arrive at your destination, sit for 5-10 seconds before turning the engine off. That's what I do.

Also, like others have said, it's better to just take it easy and let the car walk along at low speeds before shutting it off, this way air if flowing over the intercooler, radiator and so on.

When I was on the Dragon, I would let the car sit for about a minute at the bottom to cool off before turning it off. On the return trip, I just eased up on the throttle once I hit the NC state line and drove slowly to the pit stop there. When I finish a session at the track (VIR), I take a short drive around the parking lot or on the exit road to South course to let the engine, turbo and brakes cool.

Water cooled and no turbo timer no need

You're just wasting gas

[VR420man]

its not just "cooling the turbo" that they do a cooling process its having hot oil in the turbo and if the turbo is red hot when you shut the car off it can super heat the oil and actually gum up the bearings in the turbo and in turn starve the turbo of oil. this most likely wont happen with the new oils we use in our engines so just as long as you not beating the cr@p out of you car and shutting it right off you should fine......

[betterthansx]

99% of, if not all, modern cars do not require this. If you are romping on the car at the track, stop and give it 5-10 seconds then shut her down. Like someone else mentioned, these cars have electric water pumps that will circulate water to cool the turbo/engine after the car is turned off. Turbo timers are just a waste of money on modern cars, but of course Greddy, HKS etc...will tell you otherwise, they have a part to sell. For every second you have the car sitting and idling, you are getting 0mpg...hurts

While I agree with the "just take it easy for the last few miles of your trip" crowd, sometimes that's not possible. If I'm deep into the boost right up to when I reach my destination, I just let it idle for a minute or so before I shut it off. Maybe it isn't necessary as some say, but it makes me feel better about it.

Water lines are there for a reason..

Well i honestly thought the responses will be different but that's good to know. ^_^

Doesn't the Manual tell you to let it idle for a few minutes after a hard drive?

I wouldn't think so. I don't think "hard drive" would be found anywhere in the manual. Vw expects you to drive the car the way 99 year olds who want to live to 100 would drive.

I usually wait 5-10 sec then shut down after normal driving. After spirited driving I usually just take it easy for a few miles. I always open my hood to let her cool down when I'm home & other places that I can.

These engines have an after-run coolant pump, no need to wait or purchase a turbo timer. For those with an R enjoy, i'm jealous!
