Comparing Fords 2023 High Output Turbocharger To Its Little Brother... Worth $100 Per HP?

[@diesel-technology5507]

The cooled compressor housing is all about keeping the tolerance of the air gap between the wheel and housing consistent, so they can use a tighter overall tolerance and not have the heat expansion of the cover cause any issues with the air gap. The efficiency of the turbocharger increases significantly so the compressor doesn't increase in size but the air density increases a lot due to the efficiency of the unit

[@Duramaxtuner]

@diesel-technology5507 Great theory! I will try to check compare the tolerances between the compressor wheel and housing and let you know what we find.

[@Micah_Makes]

​@@DuramaxtunerI'm came to say the same thing. It isn't a theory.

[@WiredNautical]

This is definitely the reason, At the end of the day efficiency is what its all about.

[@sleestack1976]

Protecting tolerances has to be it, that air isnt in there long enough and the sink area not big enough to be an effective heat transfer.

[@LWRC]

@5:34 you don't know for sure why Ford put engine coolant through the turbo compressor cover! And yet, you keep saying there are no differences between the standard turbo and HO turbo except for the coolant circuit! Pretty obvious you do not understand the engineering that went into the HO turbo! If you don't understand it, how can you criticize it??!!! Just fyi - the coolant in the compressor cover is not for cooling the charge air! It is for cooling the bearings!

[@JEREMIAH_TC]

You missed the part where on the high output they now have stainless steel exhaust manifold and stainless steel bolts, bolting at manifold to the engine. Not only is the turbo housing code, but the lines are cooled

[@Duramaxtuner]

Noted, thanks!

[@VegasGuy1975]

When it comes to thermodynamics one of the most important rules to consider is that cooling the air at the point where it’s actually being heated is the best chance you have to control the effect of the boost. It’s a simple as that. It’s a lot more expensive to do this as it requires a lot of precision machining and additional complexity, but cooling the air at its earliest point where it’s being heated is a great idea. It’s also worth noting that the stated 25 horsepower and 120 foot pounds of torque is incorrect. It’s 25 horses and 150 foot pounds of torque.

[@cnetate]

I traded my 21 ram 3500 HO that was tuned by you guys. Even when a tune, the truck just wasnt fun to drive a felt like a semi. Im not gonna lie, I ram my 15 ram 3500 ho and my 21 on the 100hp tunes while towing but you can definitely tell the truck pulled power pulling up the passes on I70 in CO. My 21 would easily get to 250 degrees. After three rams and ram not doing anything in 24, I decided to buy a 23 ford f350 lariat ultimate HO. Im blown away at the power of this truck, I pulled the same passed with the tuck with about 6k miles on it, doing the speed limit, for the most part. My ram couldn't do that with the tuns. I'm so happy with this 23. Fuel milage is great and truck feels solid. Highest temps I saw pulling was 210 deg. This is the first truck I've own where I'm thinking, this doesn't need a tune.. But it's always tempting. Is there gonna be turning for the 23s? I hear with tuning, the bottom end bearings go bad on the ps 6.7..hammering the bearing?

[@Duramaxtuner]

@cnetate Yes we do have tuning for the 2023 HO Powerstroke in the works. What the difference in power between the standard output tune and the new high output tune will be, we are not sure of yet. More testing still needs to be done. We haven't heard anything about bearings going bad in the 6.7Ls.

[@shmes9]

I believe it's because certain tunes have up the feeling down low in the RPM range and that increased cylinder pressure let's say below 1,600 RPM maybe higher is very hard on the rods and crank and it wipes the bearings out it's not as much as an issue in the inline 6 because of the strength and the design but it is in the V8 design not all engines are created equal though in the V8 world so each one has a certain limit

[@jameshenson4871]

cnetate something sounds funny about this comparison

[@jakeshupe79]

Silber turbo has been using a liquid cooled compressor housing on turbo snowmobile kits for years. It makes a huge difference on charge air temps. To the point on a long hill climb being able to hold your hand on the compressor housing vs being burned. My 23 ho will definitely out pull my 22 i traded it in for. Both pulling the same 40ft fifth wheel.

Great application of prior knowledge @jakeshupe79 and thank you for your insight on the 2023 HO Powertstroke compared to the 2022 SO as well.

[@andyradlgruber5315]

The coolant jacket helps keep the compressor wheel blade tip clearance as tight as possible. They use the technology on industrial gas turbines, but they do it on the turbine side to minimize efficiency losses. Aluminum expands greater than steel when heated, so your compressor case will grow and you'll end up with compressor losses when it gets hot. They cool it to keep it tight.

[@Uncle_Fester24]

Excellent video! I learned a lot. Thank you.

[@chadgardnerdds3197]

Look up “Chester’s Extreme Diesel at Monroe Civic Center.” The man didn’t finish high school, but one of his upgrades is adding a cooling system to the turbos since ~2005 & now I understand why! He can’t juice up the aluminum frame 3/4 tons or they bend under heavy acceleration. He just reworked my father in law’s Silverado 1500 3.0L diesel engine, powertrain & suspension so it can pull 35k+ lbs around the farm with zero problems. Cooled turbos were installed along with his other typical “upgrades.”

[@Duramaxtuner]

You won't be disappointed. Maybe down the road, we can tune it for ya!

[@Mr42960]

My opinion, my 08 Ford 6.4 had a huge conventional air to air intercooler but my subsequent 6.7's had the small brick air to water. I think for tuning and control consistency Ford just gave up and decided to tune around an air charge that was hotter but had less temperature variation overall. I agree with your cooling passage design intent extrapolation.

[@Duramaxtuner]

@Mr42960 Totally agree with your logic here. Lots of modern cars run engine coolant through the intake throttle body for this same reason.

[@revrdr600ho]

The next question is... Can you use that to your advantage to and create more power with the tunes you are developing for the 23+ trucks?

[@Duramaxtuner]

@revrdr600ho Haha, great minds think alike! We were just discussing this amongst staff today. We will let you know as soon as we have some more insights.

[@trueamerican7034]

All Ford fid was listen to Gale Banks, want mor power increase the sir density, basically anything you can do to cool the air will make or have the ability to make more power

[@aaronkelley8909]

Good explanation and theory! Thank you.

[@claybilton8000]

Cooling the air during compression should increase volumetric efficiency and decrease the hp demand on the compression wheel and provide more mass flow into the engine with the same energy into the turbo as well as other benefits such as less coking of oil at higher pressures and temperatures that would be present without the cooling. Mass flow is what matters. Lower temp is more mass at same volume flow or acfm.

[@texan77581]

Excellent video. I think a driver would definitely feel the extra torque pulling a trailer in mountains. Maybe some of the extra cost is warranty

[@williamvaughan1218]

Which coolant source is going to the compressor housing? Coolant from the engine coolant system or from the low temperature cooling system?

[@nahrens223]

I feel that this is an emissions and efficiency solution to cope with a higher output. Case and point. Both the maxxforce HO and the C15 acert CATs use staged intercooling to help cool the incoming charge air between the turbos to help keep secondary turbo from getting cooked by the hot incoming air from the primary turbo and this solution also aids immensely in preventing the primary intercooler from getting heat soaked during hard pulls which would otherwise create anexcessively hot intake charge and enable poor emissions thus making the whole after treatment work overtime to keep emissions in check. These are purely my assumptions as to why ford chose this setup.

[@nickpriegnitz5895]

I appreciate the insight on how the class 8 tech might be trickling down into the light duty stuff. One thing is for sure, they're getting close to the single turbocharger PR limits and will probably start revisiting the staged compressor systems again (re:6.4PS) if the HP races continue.

[@Duramaxtuner]

@nahrens223 Great correlation! It would definitely be interesting to see how well this turbo could improve cooling on a compound setup, especially without an intermediate intercooler.

[@nahrens223]

@nickpriegnitz5895 I feel that in due time a compound or sequential turbo setup similar to either the 6.4ps or ISV5.0 cummins will have to be revisited as well as long and EPA keeps requiring cleaner emissions all the while we the consumer keep demanding more power. I am also quite interested is seeing how Speed of Air dimpled pistons play into all of this as well.

[@KentSwanson-ol7ht]

What would it take to upgrade to high output. Is it just a turbo swap. I heard that the high output was water cooled vs the base 6.7 was not.

[@robertsloane1268]

Water cooled turbos are common on marine diesel engines Air cooling, on compressor is paramount at high boost. Charge air cooler might need a smalll boost ..hence they water cooled turbo Eco boost turbos are water cooled

[@nickpriegnitz5895]

These turbos have water cooled cartridges as well (like the ecoboost) and most other OEM turbos today. The water cooled compressor cover is in addition to the cartridge cooling.

[@MW-jj1rn]

I have been wondering about this. What about the injectors? I’m surprised Ford hasn’t offered this as an upgrade option for the standard 6.7 - performance shop. I’d like upgrade my 21 but not void warranty.

[@Duramaxtuner]

Haven't dived into the injectors yet. Interested though!

[@blakew1026]

They did up the fuel pressure from 30k to 36k. But I think the injectors themselves are the same

[@Re-engineer_everything]

I would like a dedicated radiator and coolant system for a compressor face for my stock and S475 please.

[@Duramaxtuner]

@JeremyCricket That would certainly be an interesting setup to test out. The question is how much the improvement to cooling would affect your air mass versus the cost of plumbing a completely separate system. Would love to see someone test this out though.

[@taylorjaniski7574]

What about cab & chassis trucks? Same turbos? I know 11-16 17-19 all had different turbos compared to pickups. Hows that relate to the commercial truck side?

[@Duramaxtuner]

@taylorjaniski7574 All Cab and Chassis models are de-rated from the factory. Which means that the factory tunes them to make less power in order to ensure longevity of the engine. This however, means that a HO option for Cab & Chassis trucks would be completely unnecessary. since it would be de-rated to below the power of the SO model. So to answer your question, none of the info in this video will be relevant to Cab & Chassis models since all of them will come with the SO model from the factory.

[@CTECH-REVIEW]

Great video and very helpful. I talked about this is one of my videos also. I know Ford also ran higher gauge stainless up pipes on the HO motor to help with longer term durability. And I also believe some of the HO truck variants get a larger rear axle. To confirm are you saying you only see 125ft lbs of torque more at 1100rpm and it doesn’t carry that difference through the rpm band?

[@Duramaxtuner]

@barry1me The 125 additional ft-lbs of torque at 1100RPM is a stat that Ford provided us with. We have not done our own independent testing to prove or disprove this. However, since this is the only place in the RMP range they gave us a measurement from I think it's mildly safe to assume that 1100 RPM is where you will see the largest increase and it will likely taper off from there slightly.

[@barrthom603]

Good to know, I had a 2020 SO, and we compared a 22 SO to my 23 HO and we could tell that the 23 HO felt noticably stronger towing 15k lb wise on the highway pulling some slight grade. Also havent noticed any downside to fuel economy either. The HO motor seems to be a monster, I hope they are durable.@@Duramaxtuner

[@evoemperor3776]

So apart from turbo any internal upgrades to the engine?

[@TheOutdoorDaileys]

Compression ratio is dropped from 15.8:1 to 15.2:1. I think those are the correct numbers. The injectors flow 6% more fuel and the HO version has stainless up pipes to the turbo. There's probably more that I'm forgetting or can't remember

It's 25HP and 150ft lbs of Torque. It was hard hearing you say 120ft lbs repeatedly. The SO 6.7 is 475hp and 1050 torque. The HO is 500hp and 1200 torque. A quick google search tuned up what looks to be the reason for water cooling the turbo...keeping the bearings cooler for longevity. Having said that I appreciate your content and what you tried to accomplish with your video. There is more going on with the HO than just the turbo..I know for example they changed the discharge pipes and exhaust manifold. May not contribute to the HP and TQ numbers but goes to increased reliability? Food for thought. I can't tell if your making fun or actually trying to understand the differences that make up the additional 150hp and 25 tq. Seems like a balance to me. Small changes to eek out a little mor hp and tq along with increased reliability.

[@Duramaxtuner]

@pat9125 The bearing cooling definitely makes sense as turbo temperatures play a large role in the life of the bearings. Also our bad on the specs. You are certainly correct that it is 150ft/lbs and not 120ft/lbs

​@@jasonkubitz9410 Our tuning is designed and tested to be safe for your engine in a multitude of ways. We first try to understand what the limits of each vehicle's drivetrain are either by getting info from the manufacturers or by testing in the real world. We then test our tunes on company-owned trucks for up to a month to determine how well the truck's drivetrain handles the added power. In the case of our 2017 Powerstroke we have taken it to multiple sled pulling events with no engine issues so far. We want to be sure we are protecting customers' trucks because it protects our reputation as well. For the 2017 Powerstroke we offer two levels of towing-oriented tunes. Our heavy tune is designed for vehicles that tow up to gross vehicle weight and adds an additional 30rwhp and 65 ft-lbs of torque to your truck. However, if you aren't towing more than 8,000lbs our light tow tune can add up to 60rwhp and 130 ft-lbs of torque. We also highly recommend adding TCM tuning as well, especially if you tow. It can help inpove the durability of your transmission by increasing line pressure and clutch holding capacity. Plus it helps transfer more of the trucks additional power to the wheels using better optimized shift points.

[@TheAnonymous1one]

Maybe it’s a reliability thing. If you are towing full weight up a hill WOT for long periods of time I assume high heat from the exhaust side will eventually soak into it. Instead of cooling from center cartridge maybe they decide to pull the heat out from compressor side to get advantage of keeping charge air cooler plus keeping the turbo cooler overall for longevity.

[@Duramaxtuner]

@TheAnonymous1one The center cartridge is cooled along with the compressor cover. However, it could definitely have to do with the reliability of the turbo over an extended period under high load.
