turbos

[imnuts]

Not using the turbos and staying out of boost all the time is just as bad for their life as using them all the time. I would say to try to get into boost occasionally to get some work out of them. Sure it kills your fuel economy, but it is probably good for them. Otherwise they're sitting there with stuff potentially building up inside.

In any event, there needs to be a power source to push the oil thru the engine & turbos. Either there is a pump or an airbottle type... I don't see that in my truck. So tell me where it is>

They last longer if you don't use them... hm-m-m... gonna remember that... Seriously, be careful if you top a hill and go right into a steep enough down hill to cause the engine to go into off mode... those turbos can be spinning and if oil pressure goes away... they can run dry... not good!

Always wondered about that, have to assume they thought about it when designing the truck…seeing as I’ll do a full throttle pull and then let off and brake and I’ll watch it go from boost gauge at 17 psi and rpm at 6000 to engine off within a 5 second time span lol.

As for the use or dont use the turbos debate, I don’t think you could really ever get to the point of not using the turbos enough that it causes harm in this truck. Climb any hill for long enough to kill the battery and you’ll get turbo boost. My sentiment is just drive it like you normally would, no need to goose it, no need to baby it. If you need the turbos, light them up. If you don’t, then don’t

Also keep in mind that as long as the ICE is running, those turbos be spooling. They may not be spooling enough to make boost, but if exhaust gasses are generated, the turbo is spooling.

Mine goes to zero Engine off...

How do you see that

I believe the snails Ford uses in this motor is BorgWarner, so they are designed to last.

I had a BMW twin turbo that, thankfully, was under extended warranty. Turbos were $10k. But that's BMW, not Ford. I hear EcoBoost turbos last a long time with clean oil. Some folks get >>200k miles

Im on my 3rd 3.5 liter ecoboost in 12 years
5 yrs in my flex
6 yrs in my Expedition EL
first year w my F150 powerboost. Never any turbo issues
The 3.5 EB has always had plenty of power on original plumbing .

I see that by looking at the screen readout... I know that it represents a switch... Point is: it goes to zero. Get serious, if the engine is off its attached oil pump isn't pumping. So where does the oil pressure come from? Either there is an electric pump or a pressurized bladder over oil pushing it out... There is no other way. So show me one of these in the Powerboost.
