Rest your Turbos when you park before turning off car?

[Vanimalious]

I typically take a moment to set music before rolling, but as long as you aren't revving the engine or driving hard, the time it takes to low throttle/idle going into your neighborhood to your parking spot is enough time to circulate imo.

The ford ecoboost engines are designed in a way to prevent damage caused by this. They have to expect the majority of people to turn the car off when they reach the destination. To prevent warranty claims, as the engine is cooling the temperature difference between coolant in turbo and block will continue to move coolant through the turbo with the engine off.

This is either a 2.7 thing or it is bullshit. My ranger gets no rest.

This is nothing new and isnt fords fault. You dont have to let it run. Its for the longevity of the turbo. Any turbo. To circulate relatively cooler oil through it. But this goes for any turbo driven vehicle especially ones that are created high temps. But not fords fault . These turbos are tiny. Not sure how much heat they are actually creating. I would let my diesel superduty 6.7 cool down after driving cuz it was deleted but I wont be letting this bronco cool.

The ecoboost motors don't require any special treatment for cooling down unless you have gotten the motor exceedingly hot, in which case, allowing the temperature to drop will certainly be helpful... but if your coolant temps are under 230, I would not even think twice about shutting it down and walking away.

Also, you probably shouldn't be beating in the motor until it hits 160... but you are not likely going to hurt driving normally right after starting it up. That said, I will still accelerate briskly even under 160 degrees, but not going WOT until past 160.

What do I base this on? The advice of Corky Bell (who knows a little about turbos), my dyno experience, my personal research, and look of the turbos after 230k miles on a 2011 Ecoboost 3.5 engine (they looked damn near new).

Most importantly is to use an oil that is going to resist breaking down under high heat loads - Mobile One Synthetic has never failed me in this regard, so I continue to use it. There are better synthetic oils, but Mobile One is a good balance of price to performance.

I’ve been running a 1st generation 3.5 liter ecoboost in a 2013 ford flex, with an aftermarket tune, axle-back exhaust, and some other goodies, which shaved 1.5 seconds off of the stock 0-60 time. I’ve never paid attention to the turbos other than getting them to breath easier for more power. And I’m at 175,000 miles without a hint of any problems. 20k miles on my wildtrak since receiving it in may, which is a later/improved generation ecoboost. I’m not worried.

Hey everyone!

I just found something out! We should be resting our Turbos when you park before turning off car! Not only should we warm up our cars but we should let them rest first or else the Turbos will die!

This might come as a shock but when I was reading and I read that I was immediately so worried my Turbos will be dead! I'm at 4k miles and I know I have not let the SavSqch (thats my Broncos name) rest!

I am so upset FORD never told me this and between not knowing if you put 3quarts of oil or 11 quarts in engine and now this Im so upset my Bronco may not have a life of happiness and longevity!

What do you all do for your Turbos after you drive? Do you sit and rest, then turn off? I think after reading this the only acceptable time to shut off immediately is if you have turtle head poking out and you need to hit the can. Then screw the Turbos for that one time and go poop!

Am I in the minority by not resting the Bronco?

This is a concern in older cars. 30 years ago metallurgy and oils were not as good as they are now.. In current street cars with modern technology and better lubrication, it is not a concern. The days of requiring turbo timers etc. are over. No need for worry, your bronco will be fine.

And this is why someone needs to come out with a turbo timer for the bronco

that's a joke, right?

unlike a catch can, an aftermarket turbo timer probably really would void the engine warranty.

I mean no it’s not bc that’s what they do is exactly what people are describing… let’s the turbo cool down before shutting off the engine. For the record I specifically asked my dealership what would void the warranty before mine was delivered and I quote “if you bypass or negate the cat or put a downpipe on”. Not sure why helping the turbo cool down would void a warranty. Some dealers a complete dipshits that shouldn’t be allowed to sell vehicles to people and I’m sure they would try to give you a hard time but it’s only helping the turbo, which by the way will fail at 90-100k miles when no one has a warranty bc that’s what they’re designed to do

CLUE: IT HAS NOTHING TO DO WITH TURBO TIMINGS
A turbo timer sounds like something that measures how long a turbocharger can be allowed to spool up.

Instead, a turbo timer works by keeping the engine running a while longer before it is switched off.

Why is this so?

IT’S A QUESTION OF OIL
We all know engine oil is designed to lubricate engine parts, prevent deposit buildup and remove harmful contaminants by suspending them.

Now, the turbochargers are also cooled using the engine oil. The idea of a turbo timer is to keep the engine running, so that oil continues to circulate.

This helps cool down the turbochargers and prevent sludge from forming.

DOES MY CAR NEED ONE?
It all depends on your car and how you drive it.

But if you’re one of the many who simply use their car to get to work and back, you don’t need a turbo timer.

Most regular drivers will never drive their cars hard enough to require such a device.

Don’t let your fellow enthusiasts fool you into thinking you need one. Especially when they talk about carbon deposits and a failed turbocharger.

IF I DON’T USE ONE, CAN I LET MY CAR IDLE?
You could, but you’d only be wasting your time and fuel.

The only turbocharged cars that need a turbo timer are of the racecar variety.

Don’t let your engine idle for more than a minute. Remember, under NEA (National Environment Agency) regulations, drivers cannot do this.

And if you’re driving a naturally aspirated (that’s non-turbocharged) car, you definitely don’t need to let it idle before switching off the engine.

WHY DON’T I GET A TURBO TIMER JUST TO BE SAFE?
Well, if you do plan on heavily modifying your car, then sure. The workshop doing the tuning will probably recommend that you install one as well.

But if you aren’t, then it’s a waste of money. You’ll be spending on a component that your car doesn’t actually need.

================
then's there's this:

“During normal turbo operation, the turbo receives most of its bearing cooling through oil,” said Keith Plagens, turbo system engineer. “After shut down, the problems with turbos in the past were you would get coking in the center bearing. Oil would collect in the bearings, the heat soaks in and the oil would start to coke on the side and foul the bearing. Water cooling – used in the EcoBoost engine – eliminates that worry.”

The new EcoBoost V-6 uses two Honeywell GT15 water-cooled turbos.

“The EcoBoost engine uses passive thermal siphoning for water cooling,” Plagens explains. “During normal engine operation, the engine’s water pump cycles coolant through the center bearing. After engine shutdown renders the water pump inactive, the coolant flow reverses. Coolant heats up and flows away from the turbocharger water jacket, pulling fresh, cool coolant in behind. This highly effective coolant process is completely silent to the driver, continuing to protect the turbocharger.”

================

conclusions:

1. ford eco boost uses water-cooled turbos (not oil cooled)
2. ford has implemented features in the engine design which eliminate the need for 'turbo timers'

This is exactly what I was talking about!

 

[lewishamilton]

Interesting... I didn't know we need this, but my other car is an mk7 golf R, the car's fan will still keep running after you turn it off. Because of this, a lot of people run to me in gas station and tell me I have to turn off my car first, and I have to explain my car is like that and sometimes I have to show my dash to make people believe me.

 

[DocFuller]

So there was wayyyyy too many pages to read through so pardon if it was covered, but for everyone who’s saying to wait after you park because the turbos will get damaged….uhm sorry to say but from the factory your vehicle is made to turn off at red lights, ya know, intermittent driving and such….so no I don’t feel the need to wait any amount of time after I park. If I’m finishing a song, great, otherwise drive your bronco and don’t worry about damaging it.

 

[AMTRV]

And this is why someone needs to come out with a turbo timer for the bronco

Ain’t happening because it doesn’t need to.

 

[HoosierDaddy]

That's old school thinking. Back before the days of ceramic ball bearings, water cooled turbos, and super thin oil.

^^^^ Came here for this.

For normal usage, the old issue of coking the oil has been designed out.

Only if I've been ripping down the interstate a long time or towing heavy etc ... maybe let it idle for a small bit, but the ride into the rest stop/fuel station for example counts as cooling down time also ... that turbo ain't working at that point.
