She is a lengthy one, no doubt. It’s got the long box, the crew cab. You lose minimal heat energy, as well as minimal pumping energy, and so a lot more of that energy is transferred directly into mechanical energy to turn that turbo and give you more power. So, I really like why Ford did this. It makes complete sense.

Well, we got another snowy morning here, and what do we have? We have a 2022 F-250 Super Duty with the legendary 6.7 Power Stroke, and I cannot wait to get into here and show you guys what I think about this 6.7 Power Stroke as a licensed diesel mechanic. So, let’s get into her.

Well, we made her to the shop. The weather is not the kindest out there, but yes, this is the truck right here. She is a lengthy one, no doubt. It’s got the long box, the crew cab. It’s really just a work truck, but it does have the 6.7 Power Stroke, which is what I wanted. It’s still not a bad-looking truck for being basically like, I don’t know what they call it, a Tradesman trim or whatever. But, yeah, I mean, you got Power Stroke dual exhaust there, always a key feature of the Power Strokes. I mean, the one thing that always looks weird on these things is the massive chin splitter, but I guess I get it. If it’s just a work truck, you might as well get that fuel economy. If it was my personal truck, I’d take that thing right off. I don’t care how much fuel economy it saves. But, yeah, we’ll let this thing drip off here. I’m going to finish my coffee, and then, we’ll pop the hood right there and get down to some business.

So, I’ve given reviews on the 6.7 Cummins, the 6.6 Duramax, so I figured it was time for me to get my hands on these 6.7 Power Stroke, see what it’s all about, and that’s exactly what we’re gonna do today. We’re going to firstly go over just the specs of the engine, what it’s all about, maybe go over some things I like about it, and then obviously go over some issues, and then finally give you guys my conclusion of what I think about this 6.7 Power Stroke as a licensed diesel mechanic.

Wow, so right off the bat, the 6.7 Power Stroke debuted in 2011. It replaced the 6.4 Power Stroke, which was really not the best-built engine, nor was its predecessor, the 6.0 Power Stroke. In fact, in my opinion, the 6.0 was probably better used as a boat anchor than an actual engine. And so, this is the first in-house Ford-built Power Stroke engine. Now, I say this because before that, Ford had a very strong relationship and built engine in coordination with International and specifically the Navistar division. In fact, they made the legendary 7.3 Power Stroke, which ran from 1994 to 2004. But because of the 6.0, as well as the 6.4 issues, Ford decided to cut ties with International and build an engine completely on their own. And so far, it seems like it was a great decision. After Ford cut ties with Navistar, it seems like the International Navistar engines continued to have their downfall, and they just were not very reliable engines. Whereas these 6.7 Power Stroke was really impressing people with its power, durability, reliability, fuel economy, as well as actually longevity. So, it seems like it was a really good decision by Ford to actually invest a lot of research and development into making their own engine, and it seems like it’s paying off some dividends.

So, since 2011, there have been three generations of Power Strokes. In 2015, they kind of tweaked the engine a little bit, revamped it a little bit, gave it more power. And then, in 2020, they really boosted the numbers. They gave this thing some monstrous power numbers. This engine right here is sitting at 475 horsepower, as well as 1050 pound-feet of torque, which is a little bit wild. And I can say firsthand that this truck is actually really, really, really fast. It’s the fastest truck I’ve ever driven, and I believe the 0-60 time on a normal length F250 is like 6.1 seconds. So, it is really quick, and what’s even more shocking is in 2023, this year, they are going to be releasing a high output version of this 6.7 Power Stroke, which is going to have 500 horsepower and 1200 pound-feet of torque. Which is going to be something to see. That thing is going to be quick and have tons of power. So, this engine is very powerful.

So, today, I’m going to focus on the 2020 plus 6.7 Power Strokes just because we have the truck right here. So, let’s go over what changed in 2020 to give this engine that much power. So, one of the two big changes in 2020 with the 6.7 Power Stroke is Ford changed the Pistons in this engine. Originally, they were a lunar alloy Pistons, which is pretty standard across this whole segment. But Ford went with steel Pistons in this engine. Now, there’s a couple benefits of going with steel pistons. Number one, obviously, is strength. Number two, is the heat resistance that steel has over aluminum. And finally, number three, is the fact that steel does not expand as much as aluminum does when it gets hot. So, you can actually make the tolerances in the cylinder bore much, much tighter than you could with an aluminum alloy piston. So, that is one of the reasons why Ford was able to get so much more power out of this engine.

Now, the biggest downside of steel versus aluminum is obviously weight. Steel weighs a lot more than aluminum. But Ford, being smart, what they did is they actually shrunk the Piston down. So, the Piston is actually a very short piston. It’s very thin, and they understood that steel, yes, it is very heavy, but it’s also very strong. So, you don’t need as much of it versus aluminum. So, they got away with having much less steel but still having a steel piston, and the end result is that the Piston actually weighs pretty much the exact same as an aluminum piston. It’s a little bit heavier, but it’s really, really close. So, very smart from Ford for doing that.

The other benefit, I guess the fourth benefit, if you will, is the fact that since the Piston has shrunk down so much, there is a lot less friction between the piston and the cylinder wall. And this is just going to allow a lot more energy to be transferred into mechanical force versus heat friction energy loss in a normal aluminum piston. So, again, another way that Ford is able to make that much power out of this engine.

Now, the second big change for 2020 is the fueling system. Or the fueling system was revised. This truck right here has a fuel system that can get up to 36,000 PSI. That’s a 6,000 PSI increase over the 2019 engines. So, it is a fair bit of pressure. And because of that added injection pressure, it just means the diesel fuel is going to be atomized that much more efficiently. It needs a more clean burn, which adds more power, as well as reduced emissions. So, it’s kind of a win-win situation.

In 2024, it also revised their VGT turbo. They went with a Honeywell fully electric VGT turbo, whereas before, from 2015 to 2019, it was an electric over hydraulic VGT turbo. And what would happen is if the engine was cold or if the climate was cold, since it was hydraulically actuated, it would be a little bit slow in those colder temperatures. Now, with a fully electric VGT, it’s really going to minimize any lag whatsoever, and it’s just going to be a much more efficient power-producing unit.

Now, finally, in 2020, Ford added some strength to the engine. They actually added strength to the block. They revised and added strength to the heads themselves, as well as adding strength to the connecting rods. Because of the different Pistons, they needed to go with a different connecting rod anyway, but this connecting rod is beefier than the previous one. So, quite a bit done in 2020, and that is why this engine can produce that much more power than the previous generations of 6.7s.

So, there are five things that I really like about this V8 Diesel Power Stroke. The number one thing is the fact that it is an under square engine. Now, what that means is the fact that the stroke is actually larger than the bore of the cylinder. Now, I like that a lot for diesels because under square engines just naturally make torque very easily and very well because of the long crank throw and just gives the engine a mechanical advantage. Therefore, it makes torque very easily.

Now, almost every V8 engine comes with what’s called an over square engine, meaning that the bore is actually larger than the stroke of the piston. And there’s nothing wrong with that. In fact, it’s actually really good for high revving engines
