I've never owned a Diesel Engine. I have no intention of ever owning one since I simply don't have a need. I'm also not a Mechanical Engineer, Mechanic, nor do I have a Degree in Fluid Dynamics. But I sat here, watching this video ABSOLUTELY FASCINATED by the information and how it's presented! GREAT VIDEO!!!
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.

He doesnt have engineering experience. hes a pilot. Dimpled pistons have been tried and abandoned in the past the same as dimpling any intake components as the improvements are very limited and pointless. They also required far heavier use of dimples than seen here. Likely snake oil tbh.

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?
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.

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 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.

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.

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 love this video!!!! Back in my college days, we met Smokey Yunick. We did empirical work in our two story wind tunnel. We did golf balls and golf clubs. Great experience and our school made a few extra bucks. I have worked on Stanley steam cars to modern vehicles. One of my first bosses in engineering taught us to hack ECM code in fuegos. Listening to these guys is so mentally entertaining. And listening to the boundary layer so confirms the air curtain injection theory. This CEO soooo knows his stuff!!!!!! Lower EGTs mean Lower NOX without EGR and DEF! NICE! Love it!’nn
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!👍🏻👌🏻🛠️🔧📏
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
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
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.
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.
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.
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
This man has the best excuse in the world for having a large head..... It is absolutely FULL of freaking brains!!!! Amazing guy! Dave is smart as they come when talking engines, but even he was in awe of this dude.
Marines are often called “crayon eaters” and “jarheads” by the other branches. That stereotype could not be further from the truth. As a former usmc aviator and a double major in engineering I can assure you that the most intelligent people I’ve had the honor to work with were Marines
I love how Dave sit's there intensely trying to learn every bit of what's being told to him. Even if you've learned so much over the years, you can always take the time to learn more.
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.
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.
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
Haa Hahaa my brain is hungry for MORE Haa Hahaa & I flunked out of College lol my wife/family/friends etc believe I should be a Doctor/Engineer/Scientist etc etc Haa Hahaa big JOKE far as I’m concerned lol
I've never been too interested in diesels but since discovering this channel, my interest is definitely piqued. And the info in this video might be the most interesting and exciting I've heard about engine tech in a long time. Seems like this technology could totally change the face of engine design across the board.
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
If it works i have seen the test and it still feel to good to be true maybe in the future for me I'll finally get ahold of an l5p duramax and I'll pay to get it tested with emissions without emissions and with these pistons
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.
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!
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!!!!!!!!!
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'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!!!
I've been a diesel owner for my personal trucks since 1995. I want those pistons for my current 2024 Silverado 2500HD with the Gen 2 L5P but can't really justify the cost now that I'm retired from fire/rescue, but I feel that these will become industry standard from the factory just as soon as they get all the hours of certification done and can build them en masse. At that moment these guys will not only be famous, they will be rich. The very moment Speed of Air goes public and sells stock, I'm buying!
As long as they work the way he is describing them though it might not become a standard because the automakers will have to invest in this and that alone will cause price hikes and the next question is will people be willing to pay
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.
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.
@@kirkpalmer1709 The one that was the most advanced medium duty engine for its time made by Navistar International, not the piece of junk that was already antiquated the moment Ford started designing it.
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
Fascinating technology. Thank you Dave! ps I had 1979 vw rabbit diesel had to wait 3 months from order to ship from Germany. Mechanical injection, no turbo. 42 city 50 hwy mpg. 69 cents per gallon. Got before gas crisis and never had to wait in line for limited 10 gallon leaded.
Great video guys, really enjoyed it, Chris's explanation on how the dimples create the turbulent air flow on top of the piston, for better combustion was awesome. Looks like speed of air have a very bright future, hopefully they can break into the more common auto industry so all the EGR and DPF crap can be done away with. A diesel engine that burns more efficiently, runs quieter, better fuel economy, lower EGT with extra power, with out that evil EGR, and possibly without a DPF, wow that's very impressive...
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.
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.
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,,,
Love this! we run (4) Durmax Trucks for the last 10 years. Just like everyone else most of our problems are the DEF systems. Same on all our equipment. I would buy full rebuilds on my trucks if they can make this piston technology as and add to delete the ERG Def systems!
Fuel air mixture in the military bombs has been perfected its called a vacuum bomb & it makes them 3 times stronger blast radius sucking all the air out of the surrounding area. A combustion engine is the exact same principle.
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
$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.
I've never owned a Diesel Engine. I have no intention of ever owning one since I simply don't have a need. I'm also not a Mechanical Engineer, Mechanic, nor do I have a Degree in Fluid Dynamics.

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.
Yes, test results are very important. Here is a link of some of the independent testing results from their website.

@@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.
Didn't the guy say that SEMA certified them? Isn't that independent?
@@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…
@@DavesAutoCenterCenterville The CAT 3516 test report doesn't indicate much at all. In fact, the fuel savings was deemed "inconclusive".
What an awesome video.
I wish I had 25 percent of this
gentlemen's knowledge.
The EPA should listen to him.
With chevron being shot down by the Supreme Court. The epa no longer has power to say anything with out a vote from congress .. the alphabet agencies are tyrants and got what they had coming… neutered..
No more chevron deference! EPA will now be controlled by we the people via our elected…..
I love this video!!!! Back in my college days, we met Smokey Yunick. We did empirical work in our two story wind tunnel. We did golf balls and golf clubs. Great experience and our school made a few extra bucks.
I have worked on Stanley steam cars to modern vehicles. One of my first bosses in engineering taught us to hack ECM code in fuegos.
Listening to these guys is so mentally entertaining.
And listening to the boundary layer so confirms the air curtain injection theory.
This CEO soooo knows his stuff!!!!!!
Lower EGTs mean Lower NOX without EGR and DEF! NICE!
Love it!’nn
Wow, harrier jump jet pilot!. RESPECT.
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!👍🏻👌🏻🛠️🔧📏
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
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
He's a good sounding salesman. Let's seem some real world testing.
They have real world testing result on their website including 3rd party testing.
Like Boeing right?
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.
They already have
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.
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.
Really interesting interview. Good to see there are companies out there designing parts that can make a difference to every part of an engine.
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
This man has the best excuse in the world for having a large head..... It is absolutely FULL of freaking brains!!!! Amazing guy! Dave is smart as they come when talking engines, but even he was in awe of this dude.
Marines are often called “crayon eaters” and “jarheads” by the other branches. That stereotype could not be further from the truth. As a former usmc aviator and a double major in engineering I can assure you that the most intelligent people I’ve had the honor to work with were Marines
@@andymike6575 Worked with many engineers in aircraft overhaul industry and I would agree. 2 of the finest engineers I have worked with where Marines.
Excellent information; hope the trucking industry will get on this.
I love how Dave sit's there intensely trying to learn every bit of what's being told to him. Even if you've learned so much over the years, you can always take the time to learn more.
16:54 Love you bringing Gale Banks into this. Would love to see you do something with the folks over there!!!
Thank you for this, extremely educational. provides me hope here in California!
I wish SOA every success! Fascinating video Dave!
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.
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.
More power....cleaner ...better economy . Yup. Like it
Im working on the Mercedes diesels! Super stoked to see how they turn out
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
Haa Hahaa my brain is hungry for MORE Haa Hahaa & I flunked out of College lol my wife/family/friends etc believe I should be a Doctor/Engineer/Scientist etc etc Haa Hahaa big JOKE far as I’m concerned lol
I've never been too interested in diesels but since discovering this channel, my interest is definitely piqued. And the info in this video might be the most interesting and exciting I've heard about engine tech in a long time. Seems like this technology could totally change the face of engine design across the board.
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
@@andymike6575 the pistons are $4k
You and the boys (Speed Freaks) I never would’ve guessed that 😂😂😂😂😂❤❤❤I love these sit downs,don’t know what you’re talking about, I love it
This is literally changing the game for diesel engines. This is absolutely amazing
If it works i have seen the test and it still feel to good to be true maybe in the future for me I'll finally get ahold of an l5p duramax and I'll pay to get it tested with emissions without emissions and with these pistons
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.
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!
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, that was so awesome!🇦🇺
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!!!!!!!!!
love the tech and conversation, Dave and sons cutting edge , great spot at Formula 1 race . cheers
I was blown away with this video I would love seeing a engine like that great job and idea
Totally awesome interview and knowledge!!
Enjoyed that one very much. Thanks. Be nice to have more of those !
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?
would be neat to see this guy and talk compact tractors and diesel engines
I just LOVE this sort of Piston Head stuff. Just wow!
I am addicted to this video watched it eight times and still keep learning stuff
Dave, mic up the other guys, they have good questions we need to hear as well!
Thanks for the feedback!
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!!!
a brilliant product for those who want a brilliant product,
way to go dude your onto something.
I've been a diesel owner for my personal trucks since 1995. I want those pistons for my current 2024 Silverado 2500HD with the Gen 2 L5P but can't really justify the cost now that I'm retired from fire/rescue, but I feel that these will become industry standard from the factory just as soon as they get all the hours of certification done and can build them en masse. At that moment these guys will not only be famous, they will be rich. The very moment Speed of Air goes public and sells stock, I'm buying!
As long as they work the way he is describing them though it might not become a standard because the automakers will have to invest in this and that alone will cause price hikes and the next question is will people be willing to pay
it will add to the cost of the engine build but save a on the deleted emissions if true.
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.
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
I want to see the results, and process of them doing the 7.3, I really want to do this to mine.
Check their website they’ve already put them in a 7.3 with emissions got 500+ horses
Which 7.3? Gas or diesel?
@@kirkpalmer1709 diesel
@@kirkpalmer1709 The one that was the most advanced medium duty engine for its time made by Navistar International, not the piece of junk that was already antiquated the moment Ford started designing it.
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
Fascinating technology. Thank you Dave!
ps
I had 1979 vw rabbit diesel had to wait 3 months from order to ship from Germany. Mechanical injection, no turbo. 42 city 50 hwy mpg. 69 cents per gallon. Got before gas crisis and never had to wait in line for limited 10 gallon leaded.
I can count on one thing Dave - great information all the time
Fantastic presentation. There's still hope for the ICE! Thanks.
Nice to know they are located in my City.
Very cool and interesting interview!
Thanks guys! Keep kicking butt
Great video guys, really enjoyed it, Chris's explanation on how the dimples create the turbulent air flow on top of the piston, for better combustion was awesome. Looks like speed of air have a very bright future, hopefully they can break into the more common auto industry so all the EGR and DPF crap can be done away with. A diesel engine that burns more efficiently, runs quieter, better fuel economy, lower EGT with extra power, with out that evil EGR, and possibly without a DPF, wow that's very impressive...
Makes me want to build a 7.3 Powerstroke with these pistons and gap-less rings just to see what the emissions would look like.
Please do and slap it on a dyno and share the info
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.
I’ll run my truck to Dave’s (1997) let me try them out. I’ll do some testing.
I hope you'll actually get to do that!
If you knew nothing about diesel's or plane wings you are well informed right now. This is a great video.
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.
What an amazing meeting about combustion of an engine. So cool . Literally.
I was a GM goodwrench technician in the 80s so true Dave
I was working on them in 1973 the first year of the cat. So I totally understand it took 20 plus years to get performance back.
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,,,
20:54 I had a feeling that's what your trying to do... But actually doing it... Incredible
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.
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
23:11 I'm sure that breaking up the boundary layer increases the heat transfer to the piston. So the coating is an incredible idea to mitigate that
Got the same design pistons in my Harley..no lie...running great so far in over 10,000 miles
I need more tech content Dave! I love this these lessons! Great content. I wish you had a shop Tacoma Washington! area!
i have an lly and id really like to see the performance... Good times comimg for diesel owners
Love this! we run (4) Durmax Trucks for the last 10 years. Just like everyone else most of our problems are the DEF systems. Same on all our equipment. I would buy full rebuilds on my trucks if they can make this piston technology as and add to delete the ERG Def systems!
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.🌞🎸🚀🖖
4:40, nice way of saying you can't trust anyone, maybe even yourself!
Fuel air mixture in the military bombs has been perfected its called a vacuum bomb & it makes them 3 times stronger blast radius sucking all the air out of the surrounding area. A combustion engine is the exact same principle.
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
At one time I remember that off shore race boat’s were messing with dimple hulls on their boats but never hear anymore about that !
When something seems too good to be true, it usually is
$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.
Incredible video. The Internet doesn't deserve it.
Awsome video, i couldve watched that for 2 hours. Fascinating
One word comes to mind, WOW!
