thoughts on Ecoboost
Having too many issues with the 09 F150- The 5.4 that year is proving to be to problematic. I borrowed a friends 3.5L Ecoboost to pull my 5000lb trailer and it pulled with little effort. Looking f...

Thanks Turtle...GREAT video !
Only have one issue and is with his mix up of gas vs diesel describing the fuel PSI. IMHO, most won't pick that one up, but that is the way of it
Folks who argue dino vs synthetic engine oil won't get this one either. Yup, dino has come a long ways closing the gap with synthetic, but so has synthetic been improving at the same time. That additional headroom on specifications might make the difference down the road. Especially when it gets driven hard using that big block volumes of air/fuel in a tiny combustion chamber.
That then gets into rejection thermal management of all of those BTU's and is with surface area between a small displacement vs larger displacement.
That can be managed with higher flow rates of coolant, which up to a point tops out, and then the efficiency of each square inch matters. Play with temp differential to have higher transfer rates, to swirl, to better plenums both in & out (multi in & out paths of virgin coolant helps and is the why they had reverse coolant flow to the heads a few years)
Lubrication, and why most of the higher priced oils now claim some sort of molybdenum sulfide these days. Am still adding my own last quart, which has been mixed in a blender with MolyB powder. Have some Tungsten disulfide powder, but limited 'cuz the buddy's firm bellied up and he dropped off the face of the Internet
That added margin of better lube (the lowest coefficient of friction for additives...both MolyB and Tungsten) makes a huge difference in anything metal to metal. Like the chain-stretch wear from extreme pressure when the turbo's kick in.
Cool video and like Dustin Golley. Smart guy showing his knowledge of the engineering & technology involved

Here is a great video on the EcoBoost.
The guy does a great job of talking about the good and the problems with this engine.
When this guy talks about this being a high performance engine he is a 100% correct. This engine needs to be thought of as pretty much a race engine. As mentioned, race engines need impeccable maintenance.
Another thing about this engine and engines like this. They don't have much duty cycle. That's why class 8 diesels have a big CID displacement in them. We can make big power with a little engine but when the weather turns hot and the mountains get steep you need that big mass to displace the heat the engine produces.
In short, if you are going to pound on this engine day in and day out up steep mountains in hot weather this engine is not for you IMHO.
If you are a weekend warrior and pull a trailer now and then in easy or moderate conditions this might be a great engine for you.
