I have a 2007.5 Dodge 3500 with the 6.7 Cummins. In May 2022 I put these pistons in and I now have 58,000 miles. I have decreased EGT’s lots more torque and horsepower and way better fuel mileage. Well, worth the money spent.
@@JackLandon-zi4io South Houston Machine. Depending on what time of year and what altitude I’m at, I can get anywhere from 18 to 22 miles to the gallon unloaded. I did not set it up for economy. So considering the fuel mileage is not doing too bad.

You need two things to empirically assert that these are viable and efficacious for the public: 1. Long-term proof, ideally 500+ hours on a couple of engines 2. Dyno tests, emissions tests, MPG tests, sound tests, etc. Go to Banks and do a collab. Edit: Tests FROM the manufacturer of these pistons mean nothing. You need several third-party, non-interested parties to test them. Banks is a reputable start with good publicity. If these guys really believe in their product (and are honest), they would be running to Banks for a collab.
@@DavesAutoCenterCenterville You can't trust "independent testing results" if they are provided by the manufacturer. They have no incentive to report a failed test. Please do your own tests and report the results.
@@Steve-sf9xv maybe I explained my objection poorly. The salesman can be 100% truthful in reporting positive test results and still be hiding negative ones. Look, maybe I’m wrong, I’m willing to admit that, but this guys shtick sets off my BS alarm. Extraordinary claims require extraordinary proof and there’s just not enough independent reporting yet…
I recall learning about this theory back in the 90's in a science magazine. The study talked about how sharks swim smoothly through the water, and that the skin of the shark was rough. Basically, the rough skin creates eddy currents that act as bearings, making it flow smoothly through the water.
I have to laugh a little at this. I put dimples in the tops of pistons since 1973. The first time I saw it done was when I helped a guy rebuild a Cummins in a boat before it went to Hawaii. It did add power, but also reduced fuel consumption as well. Since then I've done it on everything diesel I've done, including an EMD as well as a CAT D399 and D398. When I got into the racing engine world, I did this on many of these engines as well, and one actually won the Daytona 500. I did some work at UCLA Engineering to figure out the reasons it worked back in the day as well. Interesting dynamics at work here. Nice video
Blimey! He said they are coming out with pistons for Mercedes OM-606. That’s my motor! I’m floored that there are still enough of these in the wild to make it worth while to design a market pistons for it. My engine is doing really well, getting 25-32 mpg…should I have it rebuilt? More power would be terrific.
After watching this, I'm with Dave. There's hope. It all comes down to the industry not shutting them out because it makes other stuff in the emissions system unnecessary. That is a multi-billion dollar industry. Those guys aren't going to be happy
I don't know of a manufacture anywhere that is designing things to last. Designed obsolescence is their goal always. How many 2024 vehicle will still be running and road worthy like the 60's-90's vehicles that were made to last with real American steel?
Having spent several decades working for one of the largest diesel engine OEMs, I can say that if this worked they would have gladly used it versus all the time and money spent developing the strategies they went to production with. This would have been a major advantage over competition and the design would have been bought.
@@D2O2 Nope. Designed obsolescence is designed into everything manufactured. If they made stuff to last longer it would run them out of business mentality. This tech will not end up in vehicles in mass for this very reason. Sure it will be available to the masses but at a much higher cost to the end user than say if it came in your vehicle.
Amen. I’m convinced the e p a has a vendetta against diesels and wants to make owning them as nightmarish as possible. Trucks would be $20,000 cheaper and would last a lot longer if it weren’t for all that faulty emissions equipment
Love these pistons. Finally, something to combat EPA standards and emissions. The emissions standards are absolutely killing motors and these pistons are great step in the right direction.
I would love to hear the difference in sound on the 7 3idi and power stroke. Great video thank tou very much I'm real interested in those pistons!!!!!!!!!
Go to their website they have a 7.3 with emissions on it. It’s getting 500+ horses. I have these pistons with 58,000 miles in my 2007 Dodge 3500 6.7 Cummins. I am very impressed.
Been following @SOA for awhile now & I can't wait to see where this is going! As a diesel enthusiasts I hate the restrictions being placed on our platforms and all the problems that come along with them! Ill be following along with you to see the progress! Hopefully i can afford a set of your pistons to someday throw into my 7.3, but I'm sure it won't die anytime soon to need a rebuild anyways. Love this stuff guys. Also love to see you 'dealing' with CARB & Comifornia along the way too, they really need 'help' down there!👍🏻👌🏻🛠️🔧📏
Do you mean because you know the design works as advertised? Those are some extraordinary claims this guy is making and he bungled a few of the explanations in this interview. Agree if these pistons really do what he is saying they will it be a game changer. I am highly skeptical however.

It was great to hear Chris P's back story about his previous career as a Marine Corps Top Gun instructor. He probably flew against some jets that I worked on for Macdonnell Douglas back in the mid 70's. "MacDac" was still building A-4M jets for the Navy and Marine Corps at that time. I am pretty sure that those jets were used as "bogeys" during the Top Gun training programs because of their extreme maneuverability against the F-14's and the F-18's. The Blue Angels were flying A-4's back then.
Absolutely great video with tons of information. So good, so much information, I watched it twice. I'll probably watch it again. I own a bunch of marine diesels with a couple coming up on overhaul. Hopefully Speed of Air makes custom pistons for models not on their list. I don't want to replace them with new engines because the new ones don't seem to be as reliable. The mileage boost is even more important in marine applications. My engines can run 24 hours for days or weeks without stops. Before I bought centrifuges I changed oil hot, engine running. Adding new oil and pumping old oil until it ran clear. Filters in a manifold for switching out hot. You have the best automotive repair business I've ever seen. Everything top notch. High quality work. No shortcuts. Repairs as perfect as possible. I know it was a lot of work getting there. The boss has a natural ability for teaching, too.
Enough talking let’s test is. Build 2 identical engines one with normal pistons one with speed of air pistons. Thats when you will see the reel differences.
You need to install the new pistons in one of your trucks and run your own test. I am sure your boys would volunteer one of their trucks for testing. You can even do a video on the build!
Has Speed of Air experimented with coating and dimpleing the cylinder head and valve surfaces? The goal being to eliminate EGR and PTF components. If the engine burns cleaner and more efficiently you don't need those systems.
You still need emissions systems because efficiency alone is never going to eliminate NOx emissions. SCR systems with DEF reduce NOx, which is one of the more harmful gases from the combustion process. Look into the science of it. DEF reacts with NOx to substantially decrease the amount of NOx coming out the tail pipe. I wish there weren’t emissions systems on trucks but they do make sense as long as they don’t constantly fail
Sounds amazing, you got to wonder how much is fluff and pipe dreams, or what tradeoffs are being downplayed. I have to correct the basic aerodynamic fallacy that was communicated, the claim that air moves quicker over the top of a wing (or dimple) because it has farther to go. There is no force or principle that requires air streams to travel equal distances in the same amount of time. Rather, pressure differentials accelerate the flow, and air over the top of a wing typically travels significantly faster than air on the bottom, and travels from leading edge to trailing edge much more quickly.
Here is some of the independent test results that you might be interested in. It would be great to see further test results as well. www.speedofair.com/r-d
@DavesAutoCenterCenterville those are testimonials. Real hard Data. He doesn't have any. It's all mostly fluff. I know people of all those categories of owners without those pistons getting similar milage.
@@alexanderzubar9593 that don't mean shit. We need mechanical proof from certified independent facilities, and more. I can go print anything and say it was a test see look at this look at that.
Yeah that’s all fine and dandy until the intake valve closes and the cylinder is under 30 plus psi of boost and god knows what combustion pressure….learn about Bernuli’s principle and pascals law 😂😂😂
@@localenterprisebroadcastin5971 I bet the dimples do nothing till TDC. At that point they may very well bring some turbulence in the combustion chamber. Hard to do, but how many have tried? That turbulence across the face of the piston would make a difference.
This is awesome, I have been following Speed of Air for a couple years when I accidentally came across their website, and I wasn't sure if it was a scam or a fly by night outfit. But now that people like yourself are interested, I can't wait until they get the certification and start putting these engines into service and not only will it improve the emissions as he said, but if you do oil analysis you can extend oil changes and put less waste oil out there, and the engines will last longer. I can see the OEM's not liking things lasting longer. I have a 2018 F150 diesel, not very popular, but I love it and would love to see what this would do to my little engine.
In as much as I truly can’t wait for the end result testing/performance of y’all’s 7.3 PS monster engine build, wanting sooo badly to do same of my spare 7.3 in shop, on engine stand, waiting to be gone thru, after watching this video & listening to everything your guest was breaking down, has my mind racing with thoughts of what sort of numbers could be ascertained from one of my 1955 Buick Nailhead 322 V8’s, incorporating these pistons⁉️‼️‼️ I’m currently building a 1966 IH Scout 800’s 152 inline (slanted; half-V8) 4 banger engine… this specific engine had interesting “semi-Hemi” designed piston tops, which conformed to the IH head specifically casted/machined of its combustion chambers! Strange shape at that too. Anywho, sadly, this original head had several cracks thru water jacket, from frozen water/coolant. Had to swap out its pistons for regular standard flat-top IH pistons that I pulled from a ‘75 IH Scout II’s 345 V8.. using one of that 345’s heads as well. Swapped rods, since diff length, new lifters, original 152 cam reworked/ground/polished, new oil pump. That 345 became a parts unit, due to half of that otherwise, low wear/milage engine, being extremely damaged by sitting water in it.. figure it was exposed to the elements w/hood open, no carb, no cover, for DECADES! Anywho, gunna be interesting to see how she (152) runs after all of this… wish I were putting in a set of these Speed Air pistons tho
Yea one of the reasons i left that a line mechanic for gm and never went back . A good choice for me . Warranty work being the next reason..i dont regret the move one bit
Dave I appreciate you guys for putting out videos like this that are packed full of information. I always learn something from your videos and I am always trying to grow my knowledge. Thank you so much. I wish I lived closer to your shop because I would most definitely apply for a mechanic position so I could gain more knowledge from you.
A very interesting concept. Most of my career was spent in engine building/machinist with the later year's spent in development, and over that time i have seen many piston development idea's from many manufacturers. I think the key to this is the computer modeling that is now available today and also CNC capability of accurate placement. Torque percentage increase is also a function of increasing the piston crown area in combination with better controlled fuel burn. All R&D is the key to the future.
I watched the first video when the salesman had the quiet engine,,, personally i was interested to see more, but i commented then 1 engine wont convince me, but listening to this discussion im more interested tan ever to see some monster engine builds,,, must admit that is nice packaging too,,,
Dave thank you so much. the info is out standing Cummins has to get these in the mix - Big fan of your vids I hope to get a monster motor in my old truck soon.
$3,770 and up for a set of piston’s, Plus Rebuild, you can buy a lot of diesel for that kind of money. Someone on here just posted the perfect answer, send it to Gale Banks and see what he says.
17:40 when that Duramax came in it was quiet because of the custom made duramax specific pistons, 2 days after an oil change with additives and treated diesel engine
Mr. Dave! You don't remember the 70's accurately! The VW Rabbit diesel started out as a 1.5 liters (50 hp) then moved up to 1.6 liters (52 hp.) Much later, came the 1.9L, after that, I lost track... (Sorry, it's the internet, there's always some guy... today, it's me.)
I am excited for the 2.0L vw tdi pistons to release. I wanna see how those little guy make gains. Total seal just needs to come out with rings for those pistons. Add that with the bosch glow plugs that moniter combustion pressure. You'd have a pretty great data pig.
It’s actually a relief to see people working in this way, truly approaching issues from first principles. It’d be great to see this rolled out to regular production engines. However, having worked in the automotive sector for over forty years, my cynical side says this will only ever be a niche product because too many people are too heavily invested in all the add-on post combustion treatments. But I do hope I’m wrong.
And who would claim of such improvements as proved without an unusual number of tests being done. Seeing is believing and I haven't seen anything yet. Less talk and more showing and while we do that we have many competitive arenas where these ideas could be demonstrated so why waste time BSing with Dave? I recall a device to create swirl in the engine intake and amazing claims for that which was all bunk. Things like this come along on a regular basis. Cold fusion anyone?

I have to correct the basic aerodynamic fallacy that was communicated, the claim that air moves quicker over the top of a wing (or dimple) because it has farther to go. There is no force or principle that requires air streams to travel equal distances in the same amount of time. Rather, pressure differentials accelerate the flow, and air over the top of a wing typically travels significantly faster than air on the bottom, and travels from leading edge to trailing edge much more quickly.
It's at least 50 % fluff
Here is some of the independent test results that you might be interested in. It would be great to see further test results as well.

@DavesAutoCenterCenterville those are testimonials. Real hard Data. He doesn't have any. It's all mostly fluff. I know people of all those categories of owners without those pistons getting similar milage.
There are many test result graphs with comparisons as well as testimonials in that link.
@@alexanderzubar9593 that don't mean shit. We need mechanical proof from certified independent facilities, and more. I can go print anything and say it was a test see look at this look at that.
20:07 The dimples basically break the air tension like when they spray water into the diving area of a swimming pool. To break up the surface tension.
I think that’s done so the high divers can judge the distance to the water
Yeah that’s all fine and dandy until the intake valve closes and the cylinder is under 30 plus psi of boost and god knows what combustion pressure….learn about Bernuli’s principle and pascals law 😂😂😂
@@localenterprisebroadcastin5971 I bet the dimples do nothing till TDC. At that point they may very well bring some turbulence in the combustion chamber. Hard to do, but
how many have tried? That turbulence across the face of the piston would make a difference.
@@localenterprisebroadcastin5971 I guess you know more the PhD engineers
This is awesome, I have been following Speed of Air for a couple years when I accidentally came across their website, and I wasn't sure if it was a scam or a fly by night outfit. But now that people like yourself are interested, I can't wait until they get the certification and start putting these engines into service and not only will it improve the emissions as he said, but if you do oil analysis you can extend oil changes and put less waste oil out there, and the engines will last longer. I can see the OEM's not liking things lasting longer. I have a 2018 F150 diesel, not very popular, but I love it and would love to see what this would do to my little engine.
Nice to know they are located in my City.
Wow, harrier jump jet pilot!. RESPECT.
whatever happened to the full-length video of the 7.3 diesel total rebuild with the new dimpled pistons?
Regarding the Excessive emissions plumbing in the late 70's into the mid 80's, I always called it a "Spaghetti Fest"!😁
Mike in San Diego.🌞🎸🚀🖖
In as much as I truly can’t wait for the end result testing/performance of y’all’s 7.3 PS monster engine build, wanting sooo badly to do same of my spare 7.3 in shop, on engine stand, waiting to be gone thru, after watching this video & listening to everything your guest was breaking down, has my mind racing with thoughts of what sort of numbers could be ascertained from one of my 1955 Buick Nailhead 322 V8’s, incorporating these pistons⁉️‼️‼️ I’m currently building a 1966 IH Scout 800’s 152 inline (slanted; half-V8) 4 banger engine… this specific engine had interesting “semi-Hemi” designed piston tops, which conformed to the IH head specifically casted/machined of its combustion chambers! Strange shape at that too. Anywho, sadly, this original head had several cracks thru water jacket, from frozen water/coolant. Had to swap out its pistons for regular standard flat-top IH pistons that I pulled from a ‘75 IH Scout II’s 345 V8.. using one of that 345’s heads as well. Swapped rods, since diff length, new lifters, original 152 cam reworked/ground/polished, new oil pump. That 345 became a parts unit, due to half of that otherwise, low wear/milage engine, being extremely damaged by sitting water in it.. figure it was exposed to the elements w/hood open, no carb, no cover, for DECADES! Anywho, gunna be interesting to see how she (152) runs after all of this… wish I were putting in a set of these Speed Air pistons tho
I really liked this video. I worked at a Chevy dealer in the late 80’s. What a nightmare of vacuum hoses and wires.
Yea one of the reasons i left that a line mechanic for gm and never went back . A good choice for me . Warranty work being the next reason..i dont regret the move one bit
16:54 Love you bringing Gale Banks into this. Would love to see you do something with the folks over there!!!
I wish SOA every success! Fascinating video Dave!
Thank you for this, extremely educational. provides me hope here in California!
I want a set for my old 7.3 powerstroke!!
Dave I appreciate you guys for putting out videos like this that are packed full of information. I always learn something from your videos and I am always trying to grow my knowledge. Thank you so much. I wish I lived closer to your shop because I would most definitely apply for a mechanic position so I could gain more knowledge from you.
would be neat to see this guy and talk compact tractors and diesel engines
12:24 VW 1.9 TDI… now I know why they didn’t email me back… can’t wait to order a set !!!
Enjoyed that one very much. Thanks. Be nice to have more of those !
A very interesting concept. Most of my career was spent in engine building/machinist with the later year's spent in development, and over that time i have seen many piston development idea's from many manufacturers. I think the key to this is the computer modeling that is now available today and also CNC capability of accurate placement. Torque percentage increase is also a function of increasing the piston crown area in combination with better controlled fuel burn. All R&D is the key to the future.
Dave, mic up the other guys, they have good questions we need to hear as well!
Thanks for the feedback!
I watched the first video when the salesman had the quiet engine,,, personally i was interested to see more, but i commented then 1 engine wont convince me, but listening to this discussion im more interested tan ever to see some monster engine builds,,, must admit that is nice packaging too,,,
my lbz is still in great shape but if or when it needs a rebuild or replacement im going to make sure i try these! super cool tech and science.
Dave thank you so much. the info is out standing Cummins has to get these in the mix - Big fan of your vids I hope to get a monster motor in my old truck soon.
I was a GM goodwrench technician in the 80s so true Dave
What an amazing meeting about combustion of an engine. So cool . Literally.
Very cool and interesting interview!
Thanks guys! Keep kicking butt
Making the 3516s reliable? Sold. I've lost count of how many gensets with those I've had to rebuild/repower in the last 15 years
$3,770 and up for a set of piston’s, Plus Rebuild, you can buy a lot of diesel for that kind of money. Someone on here just posted the perfect answer, send it to Gale Banks and see what he says.
The gapless rings might be worth the resources and effort.
Who would have thought something so simple could produce such an overall improvement
They have a fluid dynamics professor with supercomputer level programming to figure out the dimpling. That’s not very simple.
17:40 when that Duramax came in it was quiet because of the custom made duramax specific pistons, 2 days after an oil change with additives and treated diesel engine
Totally awesome interview and knowledge!!
Mr. Dave! You don't remember the 70's accurately! The VW Rabbit diesel started out as a 1.5 liters (50 hp) then moved up to 1.6 liters (52 hp.) Much later, came the 1.9L, after that, I lost track...
(Sorry, it's the internet, there's always some guy... today, it's me.)
Before I read your last sentence I was thinking exactly that 😂
I am excited for the 2.0L vw tdi pistons to release. I wanna see how those little guy make gains. Total seal just needs to come out with rings for those pistons.
Add that with the bosch glow plugs that moniter combustion pressure. You'd have a pretty great data pig.
Hey 2nd comment! Wears ball cap backwards. Sits on chair/stool backward.
It's all good.😊
love the tech and conversation, Dave and sons cutting edge , great spot at Formula 1 race . cheers
i have an lly and id really like to see the performance... Good times comimg for diesel owners
If you knew nothing about diesel's or plane wings you are well informed right now. This is a great video.
I dont even drive a truck but i watch all of daves vids lol
Wow this info is great way to bring it Dave this channel is amazing
What wouldn't I give to have a set of these for the 2GR-FKS.
These are super legit.
Very informative. Super excited on these man!
Now add Lake Speed’s Total seal gapless second ring package and deep valley cylinder hone and check the result.
So awesome to see engineers actually trying to actually solve the problems with emissions controlled diesels.
No emissions tests on diesel engines.
Clean burning diesel ;-)
LOOKS LIKE THE INDUSTRY IS FIXIN TO GO THRU MASSIVE CHANGES.....❤😂❤😂❤😂❤
Another great lesson thanks dave 😊
My pleasure!
Excellent content, thank you Dave!!!
Awsome video, i couldve watched that for 2 hours. Fascinating
It would be interesting to see this piston innovation applied to farming equipment.
It’s actually a relief to see people working in this way, truly approaching issues from first principles. It’d be great to see this rolled out to regular production engines.
However, having worked in the automotive sector for over forty years, my cynical side says this will only ever be a niche product because too many people are too heavily invested in all the add-on post combustion treatments.
But I do hope I’m wrong.
Gas applications for the coatings at least? Turbo or supercharging to reduce heat?
Awesome info about Speed of air technology
Fantastic presentation. There's still hope for the ICE! Thanks.
Great content!
Another great class down the road I have to rebuild my Duramax LB7!
The 77 Honda Civic had a pre combustion chamber in the head only vehicle that didn't require a catalytic converter at the time
I love this stuff. Who would have ever thought a dimpled piston could change so many different things
And who would claim of such improvements as proved without an unusual number of tests being done. Seeing is believing and I haven't seen anything yet. Less talk and more showing and while we do that we have many competitive arenas where these ideas could be demonstrated so why waste time BSing with Dave? I recall a device to create swirl in the engine intake and amazing claims for that which was all bunk. Things like this come along on a regular basis. Cold fusion anyone?
Man! Great Share! There is hope yet! 💪🏻🙏🏻
