New piston design increases fuel mileage power and torque. Decreases oil change interval, noise, and soot. Speed of air pistons. monsterengines.com/ to get you some
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.
@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..
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
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.
This has quickly become one of my favorite RU-vid 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.
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.
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
@@TurboGTO288 I give too much attention, which is why I was quoting the video. I don't have the time or interest to back and forth with a troll. Don't you have better things to do with your life?
@@MikeSmith-nu9wt😂. Don’t blame the engineers man they can engineer a near perfect vehicle if they wanted. But when an engineer submits his designs or ideas they get the money people up top telling them to make it cheaper. It’s not the engineers that’s just silly to think that. 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
@@Lexidezi225it 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.
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.
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.
@@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.
I'm a level 8 crank polisher/ distributor, and let me tell you! The efficiency gains I've seen in the forward and return strokes using this technology are astounding! I can deliver the heaviest of loads now in a single trip. Also by passing the savings onto my loyal customer base means that I'm making fewer tedious trips over to your mom's place!
@@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. I would not want that at all. Nothing beats the sound of a V8. I own a 67 Firebird with a 455CID, I told my brother if this engine ever needs rebuilding it's coming to you. 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
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!
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. Many thanks David in the UK.
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.😊
Dave i like your stuff so far. You seem like a straight up, honest guy who has spent years perfecting his craft or trade. Can't wait to see more on this. Increasing power, economy, longevity while lowering maintenance seems like the golden ticket.
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
Hello from England, 🏴 I came across your channel by chance and really enjoy listening to your content. Look forward to seeing you on Discovery Channel.
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.👍👍👍
Dave I used to be a mechanic and I was surprised by this piston! Pretty cool if it really works? BTW I really like your channel. You're not afraid to comment on a bad design and as a mechanic I've seen lots of bad designs, so I subscribed to your channel. Keep up the good work.
AMEN DAVE & CREW! :) I love nothing more than turning on youtube and checking out your videos and learning from them. My 2 kids 7 & 5 say can we watch The Motor man on youtube. Honestly guys love what you are doing not only in your shop but online also. Been watching for a few weeks now and been meaning to say thank you. Not only is it about motors but also relevant in life also. All the way from Gold Coast Australia. Luke.
@@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.
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.
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.
I love this stuff Dave. Those pistons are some real "Rearden Metal" style development. I'm sure you'll get some blow-back like "why try customers with an untested product?" Well, what can you say: "I trust my own judgement".
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.
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 .
@@DavesAutoCenterCenterville Thank you, much look forward to seeing developments on this issue . Greatly enjoy the videos by the way here 40 miles north of London
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'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.
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.
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.
Awesome presentation!!! I have never heard of the dimpled pistons, until now... Very interesting.... The Total seal rings , I have heard about for a long time... And they are really nice...
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.
@@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.
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.
I race jr dragsters in late 90s early 2000s. One of my engines intake port was dimpled like a golf ball, it was a very ahead of its time and fast engine.
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.
Dave i love your videos! Im a traveling construction superintendent from maine. Love working on things and learning. My son is actually moving to utah, his wife is going to be attending BYU in provo. Keep up the great content!
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
Wild Love this stuff you know I just got back from monster and you pricing is fantastic “A bit more “ and get these kind of benefits is not even a question These are a no brainer 🤙🤙🤙🤘🤘
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.
I remember my friend building small block chevy himself and he ported the heads and pistons with a golf ⛳️ ball dimple. That technology has been around for years.
I am greatly appreciative of the sharing of information that this channel provides. "Teach a man to fish". I look up to y'all immensely and happily anticipate new nuggets of wisdom.
