Need to see 2 engines with the same build except the pistons, instrumented and tested on a calibrated engine test rig on the same fuel at the same time.
- Specific fuel consumption (g per kwh)
- instrumented pistons for temp
- exhaust gas analysis.
No two engines are identical. We've built quite a few identical spec engines and optimized them on the engine Dyno and found 2% difference on 500 HP.
Honing finish and technique, ring types, etc. many factors involved.
And don't tell the guy who's doing all the tests which one has the magic pistons.
@@hotrodray6802when they are claiming 20% improvements it should be easy to see even if the engines are out a few % from each other.
@@hotrodray6802 If they alternate/swap the pistons on the two engines over multiple tests then it should be rather easy to calculate the error.
You wouldn't notice a difference between the 2! Like engine additives, this a buy me trick. Too many factors involved as well
I can't wait for Gale Banks to get a hold of a set!
My thought exactly.
Same. You know he will put every single instrument in his shop to use to check the claims. With proof of yes or ya no.
You don’t think Gale will dismiss it because it wasn’t his idea?
@seandurgin I truly believe that if it does what is says. He will back it and tell us the truth.
Just like he does when he test everyone's intake. Shows the data that they are all bull. Shows the data why they are bull..
@@seandurginnope , he has backed products that werent his
The fact that they are willing to go to a shop with the equipment in it shows they aren't trying to hide. Would definitely be interesting to see a unbiased review from this shop
Would like to see lifespan results.
Teardown analysis at 60k, 100k, 150k, etc
Exactly it does have more surface area though id think longerrrr no??? This is a good one
Well, if it’s a coating, then you could have stress and cracks and all sorts of things happening over time.
The tear down I was thinking of includes not only the piston tops, but the rings the cylinder walls, the various bearing surfaces, valves, everything.
It’s pretty safe to say, if one change in an engine, It will cause changes elsewhere
Good point, ceramic is tough as nails when it comes to heat but can also be brittle on impact.
My thought is, what if I creep into detonation territory and get a very slight ping, does that piston top shatter?
What about full on detonation?
I've had a motor detonate and shatter the front and rear-center plugs in a v6 Gas engine and the engine still runs and drives fine but isn't as smooth at idle.
The detonation wasn't that bad internally, no boost, lower RPM, when it happened. Was something with the coil pack or plug dropping out at around 90% throttle pulling from a dead stop.
The takeaway is the fact it shattered the plugs and even cracked others around the center plugs, the ceramic on the plugs.
You'll do that, yourself.😅
Can’t wait for you to do a video on a build or rebuild using that style of piston. Very interesting stuff. Thanks for sharing Dave. Take care and stay safe.
Me too
That's what I thought this video was gonna be. Not just him being paid to advertise for that company with a vid😅
First thing I thought when I heard the truck pull in.
This has quickly become one of my favorite CZcams channels. Thank you for sharing your knowledge. Please keep the videos coming as ive watched every single one on your channel so far, and it's boring on this app until I see "Daves Auto Center uploaded a new video to their channel". Haha keep em coming !!! God Bless.
Thanks, will do!
Completely agree. Keep them coming.
Same!! I hope they never change!
couldnt agree more! found them about a month ago and is now my favorite youtube channel!
SAME! I’m not even a mechanic
As a physicist, 13 to 16 mpg seems unreasonable. In the end, efficiency is physics and the only way you increase efficiency of the diesel cycle is by increasing compression ratio, increasing temp, and decreasing the temp sink. Their pistons might provide a higher compression ratio. The ceramic top might reduce heat loss (higher temp), and the heat sink (atmosphere) is going to be the same. I’m not sure you can get 20% more efficiency from these changes, and then add in environmental emissions considerations, and that makes me more skeptical. Maybe, but this definitely falls into the “show me” category.
I agree with you. I’m not a physicist, but I do understand with diesels the leaner you run, the hotter the burn and more NOx is produced.
Yeah and of the new piston is increasing compression that's definitely not some technological breakthrough.
@@hoonaticbloggs5402You mean gas motors
I happen to think this is total snake oil.
Embarrassingly so, much like engines that run on water.
@sungear
Agree on the snake oil....though engines run on water vapor, via steam isn't.
As a mechanic here, this sounds like Magical Pistons. I'd love to see some Dave tests on these Pistons!
Maybe the dimples create some kind of cushion in the combustion process or it could reduce the friction between the piston and moving flame front. Either way the same technology improved golf ball travel through the air!
@@garybulwinkle82 nope it's Voodoo
Actually the ceramic coating You can do yourself
And someone said putting dimples in the top of pistons has been around a while.
And total seal rings have been going on three decade ; maybe longer...there is one more thing drill and tap oil Jets to spay up inside tops of the pistons to cool them Even more
You are very correct to want to see some research and testing. This link from speed of air may be helpful. Thanks for watching!

They could make a vehicle last 40 years no problem but it would cost us $200,000 for a little car
Agreed, if only you could figure out how to capture all that wasted heat energy, and figure out the mechanical forces wanting to rip the ice engine to pieces. If only there was a technology that could get >90% efficiency
@@servicedogojokeguys2967it would probably cost the same, but they would have to spend more for manufacturing and couldn't mark the price up as much anymore. Car manufacturing costs are a fraction of their sale price.
Dont forget this guy has a product to sell, lets see long duration in production testing
Better in every single way with no drawbacks and yet no manufacturers employ it? 🤔
In my 19 years of automotive powertrain testing experience, this appears to be a good product idea but is giving me a little too good to be true vibe and another "re-inventing of the wheel". I'm not opposed to seeing more on this but I find it hard to believe timing events haven't been changed as well as the amount of injections per cycle since both of these things have a huge effect on diesels combustion noise. As good as it is being sold, it makes you wonder why this concept hasnt been being utilized by cummins.
20% fuel mileage is huge, hard to believe an OEM hasn’t done this
@@stephenbrown3760 According to the numbers this guy is citing: just shy of a 26% mileage increase... 25.95%.
This is just like the magic carburetor in the 70s that would get you 50 mpg on a big block that the oil companies kept hidden....
Buy a set and build a motor. Post the results as you put miles on it, make a good series.
@@stephenbrown3760 I thought the same then realized that manufacturers want to spend as little possible to make a product. I know GM changed piston design on the 3.0 Duramax and the newest version is producing a lot more torque and HP.

@@DavesAutoCenterCenterville Great idea but what will happen when government wants all EV's by 2035 or so. All this great technology will be thrown away. I hope I'm totally wrong.

Great Job to you and your team. It's obvious not only you know your trade but your also passing it down to the next generation of mechanics and builders.

@oilman1758 the government is going to find out that you can't legislate a market change. That's what's gonna happen. Electric vehicles suck. And they still will in 10 years.
@@oilman1758that's wildly unrealistic and even they know it. The power grid can't even handle existing loads as it is. Charging ONE ev once takes as much power as the power consumption of several households. So youre talking multiplying the national power supply several times over to make that realistic
Sorry Dave, if these pistons really are that much of an improvement in power and emissions -- then why hasn't every OEM started putting these in production engines? I'd like to see Gale Banks test these pistons on his dyno and measurement setup and your own real world engine builds. Make this sceptic a believer.
Perhaps auto manufacturers do not want to pay a patent royalty?
@@maxscriptguru non-sense. If the pistons really do save emissions and boost efficiency; the cost will be absorbed in the production and the OEMs benefit immediately; either by marketing more power and better economy, or paying less in CAFE fees. And if you don't think the emission controls don't cost the consumer more money. Not too long ago an auto with CA State emissions was at least $1400 more than the other 49 states (though several have adopted some of CA emission regulations, but that is a whole other can of worms). I look forward to real world testing and science data - not some single company claiming a patent with "their" own "testing" data. My Statistics professor (way back in the 80's) taught us a valuable lesson. Statistics with numbers, there are lies, damn lies, and statistics.
Other than the quieter dmax. There is no proof yet. Seems too good to be true.
People build things w death dates these days. Ford, Ram, chevy etc don't want their motors to last longer then we are not buying new trucks or cars.
Oil companies (and even car companies) could give a f about efficiency or reducing maintenance intervals or even a product that works well. It's only when new government regulations force them to make improvements that they are forced to comply. Oil companies have been know to buy up patents just to suppress discoveries that could affect their profit margins, meanwhile getting huge government subsidies, basically screwing us coming and going. Perhaps this is rediscovered technology that was suppressed by oil companies.... just a thought.
My 1974 Merc Cougar XR7, when i ported & polished the Elderbrock Intake i put in golfball dimples inside just by hand, 1992 when i had that 400M (0.020 over) out. Had lots of fun in it over the decades. Was stationed at Edwards AFB working on B2 at the time :) all of them were just under the carb & inside the runners where a die grinder w 1/8" carbide cutter fit too.
No idea or dyno testing but managed 17mpg for a long time.😊
Racing MX I got some insight on squish shaping of heads and scalloping of intake ports. This is next level and very cool!
Very cool!
The ceramic coating and porous surface makes sense, it definitely seems as though it would cut down noise levels in the engine.
It'll make the green with one shot too !! 🙄😂
Thanks for sharing Dave. I have been hearing about this technology for a few years now but never had a chance to do any testing myself, so keep us updated on any installations or testing you do.👍👍👍
This is easily one of my favorite videos from you guys! I would LOVE to see more in depth content from the Monster Engine side of things with engine break down and builds!! Either way, great content guys and happy to watch the growth! If you guys end up needing a well trained CNC Machinist, i would be willing to travel to work for a great company like you guys!
We tested this on a wet flow bench. So we took 318 heads one we put HUGE dimples into combustion chamber, one we roughed up 40grit, and one we polished. The wet flow showed the dimples and rough surface worked well to stop pooling of fuel. With polished HORRID combustion chamber of 318s it puddled on head didnt get complete "burn" or atomization AT ALL. So there is some truth to this in keeping fuel in air. Direct inj fixes that obviously. But im interested in what benefits on head of piston would be. Our dimples where much more close to each other. But it did work. Wow the noise is way reduced
Turbulence is a fantastic thing once you combine fuel & air.
Roush racing was putting dimples into intake manifold runners on Ford NASCAR motors back in the 80s similar results increased power lower fuel use
The main difference in your testing and their product is the ceramic coating on top of the piston..
@@kenkahn138 it also made the runners easy to slime up with gelled mothballs for a real good qualifying lap🤫
They placed the dimples where the injection jets spray. So there probably don't have to be many of them.
Correctly sized rod bearings make a diesel quieter, too.
This channel just continues to grow to be better and better. I just love and seriously appreciate the effort you guys put in, in achieving absolute excellance in automotive engineering. The way that you guys do not close your eyes and minds to new ways of doing stuff, is testament to your commitment in constantly moving the whole internal combustion industry forwards. Im just off to watch this video again, it really is solid gold stuff.

Thanks for the videos!
Bill and Ernie Elliott were using The golf ball dimpling on pistons and combustion chambers. Since the 1980’s in Nascar.
Until someone let the cat out of the bag, and then Nascar changed the rules to a lower mandated compression.
This is pretty incredible. I noticed how much smoother my 6.7 was when I started using scheaffer oil. Add those pistons holy crap
Looking forward to it! 2 of my favorite Automotive Channels for sure!

High octane fuel won WWII.
@@MarkSDCA its definitely on the list, along with proximity fuses for AA rounds, forced induction, shaped charge warheads. So many things that came to be as a result of ww2. As horrible as the time was it slingshotted the world ahead by decades in tech.
On a 2 stroke dirtbike engine, the squish factor comes into play.
If the compression is uneven, you build hot spots. I might dimple my next piston just to see..
Pretty cool idea.
Just a 'side thought' - the dimples would tend to lower the compression ratio and increase the total chamber volume by the amount of material removed from the dimpling process. Will that necessitate a skim of the head to restore the compression ratio? HA - or am I completely wrong? CHEERS from AUSTRALIA.
@elvispresley3340
Yes I already have a milled head and it seems to build more heat..
I love this Channel! Learning a lot from Dave and the crew... keep up the great work.
I love this channel. Thanks Dave!
I've seen some interesting results from dimpling piston tops and head ports, both intake & exhaust. Dimpling ports increases the volume but has the benefit of keeping velocity about the same, which is important. At least that's the theory. For pistons there are probably benefits in cylinder filling. The ceramic coating has advantages on its own too. I wonder if they've independently done tests of each application to see what differences there are. They probably have.
What happens when those dimples get filled with carbon build-up?
🤔
Hey Dave, you and your team are the best! God bless you guys, cant wait to see the show! Thanks dude!
I dunno squat about motors but this channel is Fantastic!! Great job Dave & Team!! Wonderful and informative videos!!

Looks and sounds like a winner Dave, I have worked diesel service and repair for all of my life but never knew this type of piston was available. I remember when Slick 50 came out and it was awesome to quiet down a Diesel engine. Wynn oil for transmissions, Minneapolis Moline G1000 had this howling noise that would make you deaf. Keep up the great work.
I remember back in the 2000s on carbed dirt bikes (cuz the 1 cylinder setup) the dimped intake ports was a thing. Even dimped intake valve. It helped the fuel atomization in the air and gives less fuel condensation on the walls. I think it is something similar can happen, increased atomization in the cylinder, better burn. Oh this atomization was just mentioned at 13:50 hehe. It would be nice to see how the hex shaped area in the piston affect the burning, and the flame shape. Looks like a lots of thought went in the piston. Great work, hats off! Can't wait for the upcoming videos with this piston.
Love this channel. Keep up the work boys
Thanks! Will do!
Dave's thumbnail face is the face my friend made when I told them what I'd do for a Klondike Bar.
Exciting piston technology premiered by Dave’s Auto Center. Thanks Dave!
I don’t work on cars anymore but damn I love this channel.Dave you have to be the most honest boss ever.Thanks for letting us ride along with you and the guys.
Highly persuasive. We need you to test a car for noise, temperatures around the engine exhaust emissions chassis dynamometer for power and torque objective road test for acceleration and fuel consumption . Then you pull the engine change the pistons and repeat all the tests. If you can show positive improvements we will believe you - then they will become standard fit for rebuilding everything everywhere .The theory does sound credible - no doubt they will be much more expensive at least initially - but if this is true it is staggering .

THIS is a Direct result of the great Show of MYTHBUSTERS where they tested wind resistance of vehicles that were dented all over the vehicles with golf ball sized dents and they proved it provided greater fuel mileage.

You know what could really use those pistons is a 7.3 or a 6.0
The dimple doesn’t surprise me on sound, VW reduced their diesel noise by adding a big dimple in the cylinder head
Talk about Excited! Man, I can't wait! This is Awesome!
Dimpling has been used for years in motorsports and 2 stroke applications to "clean up" inefficient combustion chamber design. The idea is to read the piston crown for gaswash in the carbon, and introduce dimples to create turbulence and ignite the stale areas for an even flame front/burn. The same idea as unshrouding valves, removing sharp edges and blending valve reliefs.
Been out of the business almost a decade yet strangely fascinated by your channel. Can’t wait for and hope you get your tv show.
He's already got a TV show, right here on YT!
If this piston is so great and giving a 25% increase in fuel efficiency, much longer oil change intervals and decreased exhaust temperatures, WHY are the manufacturers not using it? WHY is this being sold as an aftermarket engine rebuild and not for the OEMs to just make them with these pistons in the first place?
Imagine the look on engine manufacturers executives' faces when you tell this simple part means 25% increase in fuel efficiency and longer oil change intervals and better emissions!!! They would be breaking down the doors of this company ordering millions of them.
This is the content I like. Please make more
I've seen & heard of these @SpeedOfAir dimpled pistons for a year & a half or so now. From what I've seen\heard\watched they seem to be a very dramatic change in something like a piston thats been pretty much the same for decades if not a century or more. Adding the dimples has shown increased MPG in various vehicles of 10, 15, 20% depending on what else is going on. Thats alot of increase when your talking about a OTR semi truck going back & forth across the country every week of the year. It's like a really good increase in the combustion cylinder leaving less un-burned fuel, & overall just a cleaner exhaust coming out of the pipe\stacks. Who woulda thought golf ball dimple technology would make it into the internal combustion engine on piston faces? No one! It is crazy to see improvements like this after being the same for so long! Id put these in my 7.3 in a second....if i ever had to rebuild it cause it died, cause it probably won't. Comng up on 300k miles in my '00 f250 7.3 zf6, with nothing other than normal wear & tear maintenance stuff & I just put a new(reman) set of injections into it last summer. Shes still going strong as can be!
Fascinating! I'd love to see a production diesel sedan with these pistons someday
That would be cool!
Speed of Air technology is something new, I’ve asked if they would make piston’s for my old 7.3 but they have no plans, they make the pistons for 6.0 liter Cummins and Cat.
Yea that would be fantastic but unfortunately not as many of us with the ol 7.3 anymore to perk these guys up. Just imagine how weird it would sound with the injectors still hammering.
The cummins 5.9/6.7, cat are the bigger demand for now, so they'll focus their energy there and as demand and money comes in, expand to older engines
This channel is great because Dave’s the man. Excellent content
Glad you enjoy it!
Since they build motors it’s simple. Dyno test a motor with standard pistons and then change them out and test again. Do a ,”calab”.
Two videos in one day. This, this is good.
If it what they said it is more power more mpg and less emissions it be a game changer for the trucking industry
Lake Speed Jr shoutout to. If you want to learn on piston ring tech and oil follow him. Love the videos Dave great info
Thank you guys for sharing your wisdom
I'd love to see 2-3 different engines, 100% stock, run on a dyno for several hours each. Record power, emissions, take oil samples, etc. then do nothing but change the pistons and rings then repeat the same tests, collecting the same data.
So you put these pistons in a 6.7 Duramax, add in some Bank's upgrades and AMS oil ... I want to see that build plus all of Dave's upgrades.
That would be awesome!!!!!!! Love to see that.
no id like to see a better company that actually has decent products instead of banks, like fleece performance or similar
Dave has the best information n trades ever. I greatly appreciate him sharing his knowledge
Glad you think so!
I recently had speed of air piston put in my 6.7 Cummins from my 2020 Ram 5500. Results are,
Engine runs smothers, less vibration
Very quiet running.
Have only run about 3000 miles so far so I'm waiting for more break in before pulling firm fuel efficiency numbers. But it's looking good.
So in 3k miles you haven't even bothered paying attention to fuel efficiency?
@@volvo09With the money he spent on the Pistons swap he doesn’t care about fuel economy. It probably cost him $10,000-ish to do the piston swap.
But what about the longevity of the pistons? Do they wear out after 20000 miles?
Looking forward to seeing some results from monster engine builds,,, it still looks too good to be true,,,, better combustion, better atomisation is always going to produce power, but the egt reduction, the noise,,,, to me I need to see it, anyway will continue watching with interest
You did see it. That truck he pulled in was a diesel and it was quiet for a diesel truck.
I need more evidence than 1 truck
Great point!
Love your channel Dave. Just curious the cost of this If I had a duramax let’s say w 50k and I wanted these pistons. Thats a big overhaul. Or let’s say I had a fleet of 30? 30 motors at your rebuild price ? That’s a lot of diesel fuel. Is the juice worth the squeeze. I do love the concept
Ive been following SOA for a long time, love to see more of them. They make pistons for big rigs too, which is where my interest is beings im a trucker. Figure 20 percent increase on a over the road truck......a lot in savings!
What I have seen and heard on this video is a game changer. I would hope that this new technology would continue to grow, I am retired but am still interested in progress.
These pistons are gonna make cold starts a bitch.
Do y'all know Mark "the beard of knowledge" from Pawn Stars? I never would have guessed he had a brother who was a gearhead!

I’m sure there are even more undiscovered efficient coatings out there for pistons, and even others metal-on-metal parts of an engine.
