Finally, someone with some engineering experience and enough foresight to apply it in a manner that will actually make a difference. Smart guy. I hope they sell a million of these things.
I could see how this is a very sketchy business. Your modification is minor, the efficiency change is also minor, but if it works it's definitely worth it. Fluid dynamics is one of the most complicated physics disciplines in science, so who's going to check or verify? Especially when the thing you are changing is an event which takes microseconds, and is an explosion which is contained inside a steel sealed chamber. But the way he described it for us, it actually makes perfect sense. I believe it. But obviously trying to observe the change before and after will not be noticable. The change is over the course of millions of cycles.
@@SubvertTheStateIDK, I’d say a potential “extra” 100 to 200FtLBS of torque would indeed be noticeable. If you already have the emissions equipment removed from your vehicle, then a quick sniff test will tell you immediately that something is happening. That’s what is surprising me, it’s a legit improvement and should be greatly noticed all around. Especially if you have an EGR temp gauge installed on your truck. This is waaay less voodoo sounding than most mods sold for trucks today. That says something.
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.
@@richieburrows7928 What kind of mileage did you get before the upgrade? Do you know if there has been a change in your regen frequency? Do you have an idea how much your EGTs have decreased? Any other changes to your engine? Thanks for sharing your experience!

A warranty means nothing if you don't follow the fine print. Even then the person offering the warranty discloses if they find any reason of a failure that isn't their fault then it's void. If you were a millionaire what would you care about a warranty anyway?
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.

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.
Cummins was the last diesel to beat the EPAs specs before they made them run the def, and the EPA kept moving the goalposts. So even if you beat whats required, the EPA will move the goalposts again.
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?

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

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.

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
I wanna set of those pistons in my little 3.0 eco diesel just because I want it to last/live as long as diesels are supposed to last. very encouraging developments coming down the pipe
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.
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
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.
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.
A very interesting video, seen before on UK company using them,results are very encouraging and its reassuring to understand the technology behind this. It does appear that the use of these pistons/ring sets are a great step forward, would i try them, yes i would, even for the hell of it. Keep us informed Dave
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.
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.
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.
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!
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.
My Head Hurts! Wow so much information all positive, I worked fo Kenametal Tooling inserts in Fairlawn N.J. and everything there was coating Engineering of all inserts and I can tell this man knows his stuff. Thanks Dave for this informative video and can't wait to share it with others in the field
$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.
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 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,,,
I've been a diesel knuckle buster for about forty five years. When I was still wet behind the ears the chief engineer on the ship told me that the black smoke that diesels produce was crystals of unburned fuel. Now that I'm retired some people ask me questions about the regen systems on their tractors and semis; I tell it's a catch can that when full goes into a 1,000 degree burn cycle to git rid of the soot. And some ask if it harms the engine? Which I tell them the results aren't in; but it does cost you acres or miles per gallon because of power loss!!!
Been a diesel mechanic since’83,tractor trailer etc;been in the transit industry since’98 this is good stuff and could shut the mouths of these environmentalists wacos , unfortunately it’s all so agenda driven. Love this stuff good job guys
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.
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.
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
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.
Goof ball dimples effect how a ball moves through the air- heat conduction, material expansion etc of a piston and the effect of dimples are not related to the former. A golf manufacturer can't help there.
A borrowed concept? I’m not sure how a 3D spherical design applies directly to a forced compression 2D design when it comes to the concepts an ICE is battling VS flight pattern….just a thought. Edit: all I’m getting at is I’m not sure the golf ball guru’s are concerned with the same argument for a piston head..
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?
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.

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.
Excellent information; hope the trucking industry will get on this.
Really interesting interview. Good to see there are companies out there designing parts that can make a difference to every part of an engine.
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.
Wow, harrier jump jet pilot!. RESPECT.
Id like to see like a duramax with twin turbos so you could keep the 2 sides of the engine separate and see the exhaust on each
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.
Yes, testing is very important. If you are interested, here are some of the independent test results from their website.

@@DavesAutoCenterCenterville I'm not saying i don't trust there guys but. I rather have a independent test.
@@jorisvr There's plenty of independent test out there from T & A performance, mining companies, places in Canada etc
I think Dave’s needs to run a test and on a different engine like a 6.7 Power Stroke or Cummins
A very interesting video, seen before on UK company using them,results are very encouraging and its reassuring to understand the technology behind this. It does appear that the use of these pistons/ring sets are a great step forward, would i try them, yes i would, even for the hell of it. Keep us informed Dave
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
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.
I just LOVE this sort of Piston Head stuff. Just wow!
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.
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.
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.
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.
a brilliant product for those who want a brilliant product,
way to go dude your onto something.
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!
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.
Dave, mic up the other guys, they have good questions we need to hear as well!
Thanks for the feedback!
Thank you for this, extremely educational. provides me hope here in California!
Enjoyed that one very much. Thanks. Be nice to have more of those !
Nice to know they are located in my City.
I wish SOA every success! Fascinating video Dave!
My Head Hurts! Wow so much information all positive, I worked fo Kenametal Tooling inserts in Fairlawn N.J. and everything there was coating Engineering of all inserts and I can tell this man knows his stuff. Thanks Dave for this informative video and can't wait to share it with others in the field
Very cool and interesting interview!
Thanks guys! Keep kicking butt
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.
$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.
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 want a set for my old 7.3 powerstroke!!
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.
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,,,
I've been a diesel knuckle buster for about forty five years. When I was still wet behind the ears the chief engineer on the ship told me that the black smoke that diesels produce was crystals of unburned fuel. Now that I'm retired some people ask me questions about the regen systems on their tractors and semis; I tell it's a catch can that when full goes into a 1,000 degree burn cycle to git rid of the soot. And some ask if it harms the engine? Which I tell them the results aren't in; but it does cost you acres or miles per gallon because of power loss!!!
Been a diesel mechanic since’83,tractor trailer etc;been in the transit industry since’98 this is good stuff and could shut the mouths of these environmentalists wacos , unfortunately it’s all so agenda driven.
Love this stuff good job guys
It’s also helps lower lung cancer.
It's not as good as he claims. Most of gains are from tuning
16:54 Love you bringing Gale Banks into this. Would love to see you do something with the folks over there!!!
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.
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.
Now add Lake Speed’s Total seal gapless second ring package and deep valley cylinder hone and check the result.
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
Wow this info is great way to bring it Dave this channel is amazing
I can count on one thing Dave - great information all the time
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.
Totally awesome interview and knowledge!!
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
love the tech and conversation, Dave and sons cutting edge , great spot at Formula 1 race . cheers
What an amazing meeting about combustion of an engine. So cool . Literally.
Dave, that was so awesome!🇦🇺
They should consult golf ball manufacturers about dimple patterns. I would assume they have studied dimple patterns more than anyone😊
Goof ball dimples effect how a ball moves through the air- heat conduction, material expansion etc of a piston and the effect of dimples are not related to the former. A golf manufacturer can't help there.
Who's to say they haven't?
A borrowed concept? I’m not sure how a 3D spherical design applies directly to a forced compression 2D design when it comes to the concepts an ICE is battling VS flight pattern….just a thought.
Edit: all I’m getting at is I’m not sure the golf ball guru’s are concerned with the same argument for a piston head..
they discussed golf balls at 20:25
Good thought but an explosion and a golf ball hit through air are two different elements to test for.
Curious about what kind of backlash is received from the supplier type companies that are now cut out of profits due to your success and innovation
Fantastic presentation. There's still hope for the ICE! Thanks.
Awsome video, i couldve watched that for 2 hours. Fascinating
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 ;-)
SO GLAD to hear OM606 thrown in there 👍... When!?
This month!
I was a GM goodwrench technician in the 80s so true Dave
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.🌞🎸🚀🖖
I'd really like to see a Dyno comparison.
Loved the analogy of a medical system treat the symptom and not the cause so true👍👍😎
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?
Very informative. Super excited on these man!
12:24 VW 1.9 TDI… now I know why they didn’t email me back… can’t wait to order a set !!!
Excellent content, thank you Dave!!!
Excellent, very informative and extremely exciting to know that we can now give new life to some very good old engines while mooning the EPA.
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?
The 77 Honda Civic had a pre combustion chamber in the head only vehicle that didn't require a catalytic converter at the time
Man! Great Share! There is hope yet! 💪🏻🙏🏻
Another great class down the road I have to rebuild my Duramax LB7!
whatever happened to the full-length video of the 7.3 diesel total rebuild with the new dimpled pistons?
As a owner operator over the riad truck driver im very interested in seeing these in any Cat , Cummings, or Detroit
Another great lesson thanks dave 😊
My pleasure!
