Going In-Depth With Ford's Twin-Turbocharged V6 EcoBoost Engine

Hi guys, longtime lurker, first time poster. I just read this interesting article about the nuts and bolts of the twin turbo 3.5 liter Ford EcoBoost V6. Some nice engine porn in there too. 340 HP and 340 lb.ft. of torque starting off at 1500 RPM is incredible for a V6. Can't wait to see what this thing does when it goes into the Mustang.

Going In-Depth With Ford's Twin-Turbocharged V6 EcoBoost Engine

Interesting. We'll see how long it lasts. Most turbocharged gas engines that I can ever remember weren't the longest lasting engines. Torquey-yes. But also problematic. Let's hope Ford does their homework on this!

well diesels tend to last a long time, but from what i understand the main thing is most people dont let the engine get up to temp properly before engaging the turbo and they dont let it cool down enough when shutting the car down least thats ive heard from turbo guys

I think that has more to do with the turbo than actual engine lifespan. If you work the car hard and shut down coking of the oil in the turbo bearings can occur. Not really a big deal even in diesel trucks today unless you get it really hot, like a long tow up a steep hill, but most times with todays synthetic oils no cool down is needed. It's usually cooled off doing slow city driving/parking. The newer gas engines are starting to look a lot like diesels with spark plugs. It's even got part of the combustion chamber in the piston now.


No just what the crap am I looking at in that picture, it doesn't even tell me at that site.

Some companies use turbocharging almost exclusively and have no trouble. Saab's engines (now GM), a large percentage of Audi/VW motors, Volvo, and now BMW. The little 1.8/2.0 Audi/VW turbo five valve per cylinder motor is extremely good and is long lived, I've owned a few.

Americans typically have a sort of bad taste in their mouth from Chysler's experiments with it in the mid-80s. Modern EFI coupled with water cooled turbochargers certainly are a large improvement over dated designs.

Should be an interesting motor, but are they really going to put it in the Mustang? They could have put the old 3.8LSC motor in the Mustang but never did, would have threatened the 5L at the time.

We can't compare a diesel to a gas engine. Diesels...you can boost them at 200 psi if you want to and no fear of running them lean, or at least not as much of a problem. Gas engine-the rods HAVE to be strong if you're going to have boost down low (remember the 2.3?), pistons have to be forgiving, head need good chambers design, plug location must be good, head gaskets must be high quality (remember the 3.8??) turbos have to be able to endure 1800-2000 deg temps, etc. Theres a lot more to be concerned with on a gas engine. If a wastegate sticks shut or a hose burns away, the engine won't forgive.

I realize that modern computer controls can be programmed to take all that into consideration, but keep in mind that it just adds complexity. And I think that each one of us knows that computers aren't always perfect.

Like I said, I hope Ford does their "homework" on this!

I can't believe ford are dropping the aussie 4L inline six in favour of this 3.5L under powered junker.

We've had 500nm of torque on tap from 1800rpm for years now

the latest and unfortunatly last version has 565nm and 310kw.

Nizpro built one to the tune of 1300kw

when some one can do that the 3.5L V6, i'll become interested

Typical Maintence Nightmare and Expensive to Fix.......

Why can Ford just get a simple Small 2 Valve V8..... Oh wait a minute GM has been doing it for the last Decade... The LS series, Expandable, Simple and actually pretty efficient.....

dfree--my thoughts exactly. Pushrod engines can be efficient! And cheap to build and maintain, which reduces overall vehicle cost and/or increases the profit margin. Why can't they build a pushrod 2V V8...hell even a 4V pushrod V8 with Variable valve timing. I have an idea in my head...dual cams in the block, etc. It can work with today's technology!

Chrysler has a variable valve timing V8 coming out that also includes a variable runner manifold:

GM has been doing it for awhile and have Vortec auto motors scheduled with variable cam timing:

And Ford? Well, we're stuck with the blasted modular motors in NA that don't even have the high end valve timing and intake tricks import DOHC V8s have.
