When he attempted to obtain a patent GM bought him out with a deal that he "could not refuse". He was paid cash and they provided him with a new car every two years for the rest of his life. Just goes to prove that if our government was really serious about saving the planet we would be driving with some of these modifications today.

@@jamiel9902 Carbs have a sweet spot of perfect mixture but only for a certain level of the air flow. So a big carb will have its sweet spot on certain airflow while the small one will have it at low airflows. Since the best mix is 16part of air to 1 of petrol ... this is the target ... but very difficult to obtain for all the real engine loads situations in daily use. For a track car engine things become much more simple... But since the engine displacement= volume is always attempting to pull the same amount of air despite the engine load required ... it becomes difficult to find the perfect balance in sizing the carbs and obtaining the mix required.

We built engines for the top Sportsman class at Willow Springs and everyone with our engines finished in the top 5 every race. This class was limited to 350 c.i and a holley 390 cfm 2 barrel. We got over 430hp out of these engines on our dyno. We did cheat a little on the c.i. but the point is that you dont need a big carb to make power.

It has been proven that a bigger carb always means bigger power. I guess if you are using a small cubic inch motor that doesn’t physically need more airflow it wouldn’t matter. But if that 350ci motor with a 2barrel 390cfm makes 430hp you could easily make 550hp with a 600cfm. Richard done this test on a 292ci 4.8L and 326ci 5.3L and a 364ci 6.0L and a 408ci he done test with a Holley 500cfm -650cfm-850cfm and 1150cfm. Every motors made more power down low with the smaller carbs. But they always made more peak power with the biggest carb. Unless it was cubic inch limited. Say the 4.8L the 4.8L stopped making power when the 850cfm was installed. It made les power initial throttle hit after 1150 was installed. It flat lined around the same as the 850cfm . The motor couldn’t physically pull anymore air in.. now the 408ci gained power everywhere with the 1150cfm over the 850cfm other than first initial throttle hit. It was the same or slightly less. Only reason why is because the smaller carb had more velocity at lower rpms vs the bigger carb. So it recived more airflow on throttle wack. But once the rpms got up the 1150 velocity woke up.

Carburetors engines are most efficient at wide open throttle. The economy gain is largely from eliminating intake runner vacuum caused by the throttle butterfly blocking airflow. In small aircraft we often cruise using wide open throttle and control engine rpm with engine load by adjusting the propeller pitch. Selecting a carb that is going to operate at near max throttle during normal operation was one half of the success. The carb cheater is the genius second half of the equation. You will see less gains when you use a carb that isn't so close to max flow during normal use.

Now, after watching this series and actually seeing that options are available, adjustments that are not excessive can actually be made, and making it a somewhat reasonable vehicle to drive isn't nearly as impossible as it once seemed; its just about working using logic and information that is readily, and adjusting to what the conditions allow.

I've been a Ford dealer tech for almost 30 years. I've heard stories that a properly set up VV carb is the closest thing to fuel injection, without actually having it. VV carbs are somewhat dynamic in their operation, but work differently from your set up. I also don't think you'd get anywhere near the fuel economy that you're getting. It is impressive.

His is more akin to port injection with an idle air control valve. He may not know it but his tuning is very well done for mpg efficiency. He is essentially running on gas fumes but can dynamically rev it high for more power(and lost of gas). I doubt he will get much for speed but noone needs a fast af car. His system is very seamless when it switches from fuel efficiency and more power. 40 mpg is very possible on most V8s.

But I only ran motors that came out of the junkyards...small block 4-bolts out of junked pickups. With the tweeks I did, e.g. jetting the carb differently on the left v right because of a slight difference in centrifugal force ( running oval track, as they joke, go fast...turn left ).

My 79 year old boss, who I worked for 6 years ago, he told me a story of how the original Ford Falcon had a backfire "screen" on the intake manifold, under the carburetor body, so prevent the engine from backfiring and killing someone. Apparently it was a common thing, when early day mechanics would work on carbureted cars, when they would do a tune-up, they would have the ignition timing off, and the engine would load up, then backfire through the carburetor, blowing a huge fireball into the person's face, and the problem is, the mechanic would "inhale" violently as a scared reaction to the backfire, sucking the fire into their lungs and dying. This problem required a "screen" mesh to be put on the carburetor. My coworker said that the first Falcon's with this "screen" on the intake manifold, made something like 30 mpg, and so Ford immediately removed the screen, and mileage went down by about 50% - back to normal. The screen apparently caused super fine atomization, which made it burn twice as well.

Now, add a second mower carb with a progressive linkage system that won't allow it to open until the first carb is wide open, along with your mixture leaning device adding more air only when needed you may hit the sweet spot of cruising range and the ability to have power for long grades or mountainous driving.

Don’t be surprised. Your right about the vaporization of the carburetor but a big difference is the leaner mixture due to your controller. In my twenties I took a Fiero Gt 2.8. bored and stroked to a 3.2 with some performance enhancements and balancing. 30 mpg then added a potentiometer to the O2 sensor to fool the ECM, giving me control to lean the mixture. bumped mileage up to 38 mpg without any precision monitoring system. Didn’t lean up too much because that would burn out the catalytic converter and over heat the engine. So in hindsight I learned from my advanced engineer dad , who created the PCV valve , that Catalytic converters require unburnt full to operate. That means our modern cars with multiple CATs waste fuel so the Cats can absorb non combusted fumes so they too can burn and glow at the right temp for the catalytic process to occur .

The smaller carb is greatly increasing the air velocity which in turn increases the turbulence, which atomizes the fuel better. The only downside I can see is your horsepower cap based on the intake restriction from the small carb, but I'm sure you knew this would be the case. Personally I'd like to see you try this on a late 90's 4 cyl car, like a Civic or a Cavalier. Cheap to buy used with light, more aerodynamic bodies. Ditch the FI, swap in a small carb, and test/tune.

I think you questioned how this would do with the 390 Carb. That's exactly what I wondered. Seems like you would need to limit the amount of air allowed through the IAC Valve so the secondaries would still work, assuming it's a 4160, or integrate a throttle position sensor. I would imagine you could get some great results while the car is running on the primaries. Creates some interesting problems to solve. You have me very intrigued by this whole experiment. Guess we're getting close to the feedback carburetors of the 80's when taking it to this next step. It's been fun to follow these videos.

Also, it did not need a catalytic converter. It used a venturi to being in some fresh air to completely finish burning the unburned hydrocarbons in the hot exhaust. The EPA rigged the test and put out a bad report, killing the engine.

According to Joerge Sprave from the Slingshot Channel, it's considered "prior art" legally once you post it up online like here on KZbin or other social media, so not likely he can patent it at this point. Also according to Joerge, who happens to be a retired patent attorney, this is often better for a small time manufacturer, because having the design in the public domain protects you from having to litigate patent issues in the future. It does open you up to have your design stolen, but it basically protects a patent troll from swooping in and suing you for a design that they later patent. This came up in regards to videos on Joerge's repeating bow design, which I would highly recommend checking that video series out. Really cool tech he came up with and I learned a lot about IP law in the process.

@@ThunderHead289 You gave several valid reasons for good mileage and I have another, remember that you advanced the timing "all around." That should help mileage and at least some of that advance should be possible with a larger carb, tuned to coordinate. BUT I don't believe you got 41 mpgs for a second!! 35 miles was nowhere near enough to compensate for possible changes in the angle of the car while filling or fuel tank venting issues that might leave an air bubble in the tank (I have had several mud daubers in fuel tank vents). I think you can see why I am a big fan of spread bore and 3 barrel carburetors, though the only 3 barrel I ever saw, on UTG, had a huge, combined secondary rather than a single little primary and 2 big secondaries as I would like. I am looking forward to see if you can find a way to bring back some performance without losing the mileage, hopefully in a way that I can use to up my mileage on my Lean Burn W150 with 225 slant 6 and 1 barrel, or use when I restore my 318, 2 barrel, 1978 surfer van. In both cases I would love to reach 20 mpgs while pulling a trailer at 55.

Hey Luke. The next major question would logically be what is the cost for the little electronic unit and metering box setup? If it will take a vehicle doing an average of 25mpg to over 40mpg, that is an extra 150 miles in a 10 gallon tank, mate. That's nothing to sneeze at - and certainly a veritable Hail Mary for all the blokes out there with V8s that just want to use them as everyday runners. I'd be interested to see the results of you running the Maverick to work and back for a week - you know, including the typical daily running stuff, trips to the store etc - and see how it does. Sure, getting the electronics to work with a Holley 390 is one thing, but when she's doing so well on the lawnmower carb, why not keep going and see what happens? Then maybe run it for a couple of hundred miles WITHOUT the electronic metering unit and see whether there is still some form of savings for running a lawnmower carb on a V8....or if it definitely needs that electronic wizardry to make it do its thing. Another thought - how well did it accelerate? Was it notably down on power from the usual carb you run on it when using the lawnmower carb?

When I was growing up (60’s & 70’s) a Plymouth/Dodge dealer I knew REALLY well, friend, and he worked on our cars. He had a new vehicle come in that a customer ordered. Back then you needed tune ups and when he came in for a tune, he asked customer how was his gas mileage. Customer said it’s the best car he ever had for MPG averaging about 30-31 mpg. It had a 318 ci motor in it. When our friend opened the hood to look over he said he NEVER seen a carburetor like it. (Also back in the day, mechanics had tests or shows for competition, our friend placed 1st in state), anyway, our friend did a tune on it and customer averaged about 32-33 mpg. He called Plymouth technical department about it. Longer story short, Plymouth wanted that carb back which he removed and put shell we say ‘correct’ carb on. Customers mpg dropped back to about normal for the day, about 20-21. He wished till the day he died he would have never called tech department and just kept the carb, figured it out, then start producing them. I will till the day I pass believe government, large manufacturing etc etc are in bed together.

That said, it still racked up ~10x the death tool of the worst flu year of the last 20 years in the USA. Anyway, about the carb: Funny how many people all seem to know someone that had some special prototype carb that was secreted away back to the manufacturer. Funnier still that they all mirror the same urban legend that ended up so popular it has its own entry on Snopes.

Now it has a 350 with a 650 DP on 35's and get's terrible mileage. It runs great though! It does make you wonder with all of the tech on vehicles these days that we're not getting 50+ mpg now. Most, if not all, engines are direct injected with variable intake and exhaust cams as well as computer controlled timing. Most also have variable controlled intake runners. Many vehicles have had this tech for a couple of decades now. Kind of leads one down a conspiracy type of road!

Cars are significantly heavier than they were “back in the day”. Pretty much every advancement in engine efficiency and aero gets eaten up by the extra weight for safety systems, power draw for the accessories, but the biggest factor is engines being tuned for power versus efficiency. If required by regulators, the manufacturers could absolutely retune their engines and trade some power for better economy, but most people would rather have a higher horsepower number they never use than a higher MPG number they use every day.

The carburetor is a mechanical fluid dynamics computer that can solve third order partial differential equations with very few moving parts. All the atmospheric variables are condensed into air pressure, which changes the velocity of the air passing through the venturi. This air velocity acts as a pressure differential measurement, and the pressure differential is what meters the fuel. It is a pseudo-closed loop control system, as the fuel metering changes based on intake plenum pressure, which changes based on RPM and throttle position. I love carburetors. I have a couple of spare carbs and distributors just in case SHTF. The addition of the controlled vacuum leak modulated by wideband O2 is absolutely genius. The elegant solution is almost always the right one, and your O2 system proves this.

Yeah, I wanna see how this setup would work on a big block, big car, cruiser - something where you're not really worried about HP, torque, or speed. I think that's where this would prove the _most_ practical. Imagine something like an old Continental getting something like...30 MPG. That would be insane, especially with their normal capacity.

The auto industry could have made cars to get very high mileage decades ago. Also covered up inventions like fuel made from human waste. The oil Baron's and Auto Baron's scratch each others back to get as deep in our pockets as they can get! We need more young inventors & researchers like this guy. Awesome work and great video! Five thumb's up!!!

There is also a opposing piston design which gets higher thermal efficiency which has been done before in Aircrafts which dramatically increased range. They don't want it because gas demand will be low meaning less money made

Their worst nightmare is people making their own fuel. How many times people dumping sh-t every year and ends up giving it to the government waste treatment facilities. The "climate change" alarmism is NOT meant to save the planet, it is meant to further oppress and control the people. EV cars repeats internal combustion vehicles of relying on expendable non renewable sources. Internal combustion engine is in fact more sustainable, but being banned because it gives people too much independence.

100 mpg carburetor is a short term, the oil baron will simply cut the production and increase the price to compensate the lower demand. The oil barons will ALWAYS WIN because of never ending demand. Want to stick to the oil barons? buy a farm and make your own fuel.

This was an awesome and well-executed experiment, and proof of concept. As with any good experiment, let's examine the liabilities. Lack of power (to what degree, I guess we don't really know yet), and... what? A natural tendency to self-enrich as your foot gets further in. Is there a point where the control circuitry can no longer sufficiently compensate? It kinda feels like this is the beginnings of the spread-bore carburetor- small primaries for cruise efficiency, and big secondaries for when you encounter a tunnel... lol

lets go best of both ideas here. Briggs and strattion makes a duel venturie carburator for their vanguard series V-twins. its about double the size of what is currently installed on this 302. So even lets say you cut the milage in half thats 20+ Mpg MINIMUM. and probably double the HP. I have a 83 deville i dropped a 305 chevy engine in... time for some more experiments of my own.

I really hope you get to a point of where its perfected patented and your mass producing and sell kits and packages for both. Im very proud of you and wish you the best of luck on this endeavor. Keep going bud. You won't regret it. 🙂

Amazing video series. Opened my eyes to how much energy is getting wasted in your average car if you can get 40mpg out of an old V8... Very interesting. Thanks for sharing.....Now just get a big ball valve and hook up 2 carbs. One performance and one economy..lol

There is definitely more left in it. Please do more videos on this! Maybe put it on a dyno see how it compares to a 4 barrel. Also, I wonder what it would mpg/drivability wise with an overdrive trans or a bigger engine like maybe a 350 sbc or 351w. Love it. Definitely earned a subscription!

Great idea and follow thru! I've always like the air leak tuning idea, just never tried it. Use it on a 4 barrel next, just to get stoic. 3d print a 4 barrel intake with a side lawn mower carb for the highway.

Maybe for another episode you could drive it for a week and then calculate your fuel mileage from average driving scenarios after it has used more fuel. Or take a longer trip, maybe 100 miles round-trip.

Reminds me of a Ford Fairmont my dad had years ago with the 2.3 L carbureted four-cylinder with a five speed manual. It also got around 40 miles per gallon. That was all while meeting emissions standards and delivering power that was adequate for the time in a midsize car. Still, a great project with clever use of modern close looped devices. Would be a good project for someone on the flats such as yourself who wants to turn an old piece of American iron into a fuel economy champ

This is pretty crazy. Maybe you could hit 50 by making some additional changes. A little upsetting when you are outdoing most 4 cylinders out there on mileage, although I'm not guessing the 0-60 is too hot. Although this project was kinda done out of spite, it's been pretty fascinating to see how well it's turned out. Goes to show that no idea is necessarily too ridiculous to try >>;=)

Would be really interesting to get airflow measurements at the same speed with the four barrel vs the lawn mower carb. It would give a nice comparison on the actual airflow through the engine.
