Then that would make your diesel truck a Hybrid! You sure you wanna go there?

 

It won't be too long before we see a turbocharged gas motor in an SD.

 

There was talk in the mustang forums of an Ecoboost coyote 5.0. Since aftermarket turbo kits are pushing 600-700 horsepower, and holding together, I'd say that would be the platform for Ford to use...

 

From what i've gathered the answer to my question is fuel mileage (when loaded down) and longevity of the motor? Thats what I think. The small motor would have to work entirely too hard and wear itself out (depending on how much weight and how often) Thanks for the thoughts!

 

For a 250 and up, 8-10 slugs-n-jugs only please!....IMO the only 6 cylinder that belongs in a any HD truck is a Cat or a Cummins (and a 2 stroke Detroit 6-71 in many years past).

 

There are a couple Ford Techs who have their own YouTube channels that have posted some interesting gotchas related to the DI-turbo Ecoboost engines they're seeing. One symptom I find intriguing, is one or more dropped cylinders at less than 50K miles. Apparently the cause is carbon buildup on valves, in particular the valves where the PCV fumes are fed back into the engine. As typical, turbocharged engines where cylinder pressures are high under boost, produce quite a bit of crankcase blow-by. The fumes fed behind the valves produce excessive carbon, causing the valves to be stuck partially open. One of the techs brought this anomaly to Ford engineers who really didn't have an answer, other than pull the heads. Last I saw, Ford was working on a chemical cleaning method for the problem. Another thing one tech mentioned, was independent shops trying to clean the carbon build up on DI-turbo engines by using Seafoam or other chemical cleaners down the air intake. Ford discourages this method because it can destroy the turbocharger. The extra combustion occurring in the turbo has been causing seal failures.

As my father used to say, and is true with the EcoBoost engines; you don't get something for nothing. Smaller, more complicated engines that work harder, will probably require more expensive maintenance and live a shorter life.

 

We were looking at buying a new truck a while back (but the $47k sticker shock nixed that idea), and the salesman was reeeeeally pushing the eco. I think the 5.0 is a better engine, so he let us test drive both. I liked the 5.0 better out of the two. No lag, better performance, and way better sound. I did like the eco, power wise, and think its a good marketing ploy, but I don't believe the mileage numbers, which is their biggest supposed perk. From what I've been garhering out here in the 'real' world, they're not getting any kind of mileage like what they advertise, which isn't really much of a surprise I guess. Plus, like I told the salesmen...Those turbo's are $3,500 A PIECE, and the warranty doesn't last forever!

That's wrong Frank, the EB turbos can be had for around $600 each from Tousley Ford.

People constantly resist change, I remember similar things were said about aluminum heads on a diesel engine. And after more than ten years you very rarely hear of a problem with them. Likewise there are many DI turbocharged gas engines with lots of hard miles that are going just fine.

 

I'm working on doing exactly that. Propane injection and electric accessory drive. I won't post a thread about it until it's done though because I know it will make most people here's brain explode.

 

I would like someone to tell me how well built the ecoboost engine is. How beefy are the rods, crank etc. after 150,000 miles with some boosting, how well do the rings hold up? These questions need to be addressed.

 

Well, ok..they might be cheaper than what I was told they were, but I still don't think its worth it. It's 2 more items (plus all the other hardware to make it work) that can fail. Now if it made the mileage that ford claims, it might be a little different. It doesn't have anything to do with resisting change, hell, I like change! It's just not worth it to me, when the 5.0 option is out there.
