Yay, this is great! Always get in debates with people sticking 100 octane in a stock 212.
Yeah, I see that all the time and when you tell them 87 is better they think your insane.
@@robotcantina8957 haven't even watched it and figured the conclusion, generally nthe higher the octane the more ethanol since it's used as anti-knock agent, ethanol being lower in energy then gas generally means it has worth fuel economy, and worse power in a low compression engine
@@robotcantina8957 *Yore
@@ryanmalin *you're
100 octane in non-modified engine is stupidity ;)
To use it, thera 2 major things to do:
Add fuel on carb (100 octane have less calories)
Add ignition timing.
You need to do a test with "non ethanol" fuel too. I'm curious if that fuel actually makes a difference
Yes, we will do that next time we bring out the dyno.
Definitely try the non-ethanol. It may be the placebo effect, but every small engine (and my wife's 77 T/A) I have l works way better on non-ethanol. If you have 93 non ethanol, the advanced may get you somewhere. And lord, so, so very much less ruined carbs. . .
@@gresvig2507 the carb thing is precisely why I use non ethanol in all my small engines. Kinda curious to try the water test on the non ethanol to see how honest the gas company really is with that. But even still my bikes and toys all are carbureted and get nothing but it.
Turbo race car guys love E 85. The fuel mixture must be changed ( more fuel ) when running E85 vs standard fuel.
That shouldn't make a difference, the reason to run Non-E is to not have it gum up while sitting.. My rarely used tools all get Non-E to prevent carb rebuilds every spring.
The fact that this is obviously a ludicrous hobby project for fun, and so many people are picking apart your methods for testing absolutely boggles my mind!
It's obvious you have put a lot of effort into testing and design, keep doing what you do. I enjoy watching this project grow!
My family enjoys this project as well... It is growing and is one ludicrous hobby. 🚙🚙🚙🤓

@@kansasrose2909 Metric conversion is helpful
@@ocdman202 We love💖💖 the metric crowd. 😊
@@kansasrose2909 I use metric in wood working due the easier way to measure. I still convert back and forth to standard. On another point, weather observations went ICAO a couple years back. I prefer the old standard than METAR. Too many crazy stuff in translations. Just thinking out loud while I wait for my next episode! I think I'll marinate some ice cubes!
@@dangerousdave5915 Looking forward to more videos from ROBOT CANTINA!👍👍👍
The 93 octane made less power because ethanol has less energy than gasoline, causing it to run lean. If you retuned the carburetor for e22, you'd get a more normal idle speed and approximately the same power as the other 2.
I was hoping someone would bring this up. E85 uses 30-40% more fuel IIRC, where that lands at the E22 level I'm not certain, but running the mixture a little richer likely would help. Still not enough dynamic compression to really benefit from it though
@@AustinRBa Did you see the retail price for diesel today.??.. Oh jeez.
@@kansasrose2909 Maybe those idiot " I like to smoke out intersections as a childish attempt at dominance " diesel guys won't do that any longer.
@@bobroberts2371 Maybe not.. I noticed their personality types at intersections as well. 🤨
What about non-ethanol 93?
The methanol/H2O injection should be fun to test. Fuel injector placement can also help lower intake temps.
Worth noting that from a detonation perspective the manifold temperature is pretty much irrelevant, what we care about is the charge temperature just before the spark plug fires. This is why direct injection allows more compression or timing, the fuel directly cools the charge rather than wasting cooling potential on the inlet plumbing.
I would love to see an MW/50 system added to this project. Water injection can add a lot of power, but I doubt the engine would survive the manifold pressure required to require it.
Only a tiny fraction of the increased power MW allows in from the water flashing to steam, most of it is from allowing the engine to run higher MP without knocking.
Essentially it's used as an Octane booster. (It doesn't actually change the Octane rating, but it prevents knock the same way Octane does)
With modern fuel, 97, 100, and even 105 Octane fuels are readily available, and I'd be surprised if nothing on the engine broke before the engine started to knock on those fuels. I don't know how much boost it would take on this engine to make high Octane fuel knock, but I'm sure it would be far more than any part of the engine is designed to handle.
@@willvvf161 This is fascinating. May be JIMBO will do some testing in this regard.

Here in Germany we got "ARAL Ultimate 102". It's pricey, but has 102 octane🙂
Edit: your explanation at the beginning is true! It's a hobby. The purpose of a hobby is to put as much time and money you can get, put into something that serves almost no purpose 🤣
Octane rating in Europe is different than the US. 100 octane in the US is roughly 105 in Europe.
@@5roundsrapid263 but you cant buy 100 octane straight from a gas station pump, right? Or at least i thought so.
@@swealer you can in some places.
@@swealer yes but it got some ethonol in it if you want true 100 octane you gotta get airplane fuel its pricey and can only be baught at small municiple airports aka county airports here in most states.
@@compwiz878 yeah E85-E100 isnt petrol.. is nice corn juice🤣 its good, dont get me wrong... We had E85 in germany a while ago but they removed it completly... Dont know why, probably because they cant put the big taxes on and it was dirt cheap.
I hear so many people say they’ve been told to use premium in their one cylinders. I always respond with its a waste of money. I’ll now reference this video from now on. Thanks for testing this!
I just loved the opening speech! Keep up the good work!
Yes, do more tests with EFI + 93 octane and E85, also it might be fun to try to get it running on propane which has octane number over 100.
In EU, especially Poland, using propane for cars isn't something new. We are using a lot of new tech to run cars on it! It's called "LPG" :D And it costs around half of the price of standard(95 RON, ~89-91 AKI[usdm/canada]). But it's using around 10-15% more of it. But still, You can get better performance on it due to higher rating(around 105-110 RON) and by that a bit of ign adv, but that is neglegible improvements in terms of city commuters. Have You ever used a car with 1.4 sohc with 77hp? It's painfully slow, even compared to ~150hp that can be found in most new city commuters with 1.0Turbo.
@@mmllmmll22 Yeah I'm from CZ so I know LPG very well :D But I wrote propane as I don't think Americans know about it, but it would be interesting if he could come up with something and drive it with the Speeduino (which I know can be done).
@@snap_oversteer we know propane here in America. Used mostly for heating but there are industrial applications as well... A common one would be propane powered fork trucks. We also know and use LPG for certain applications @Xserabis
@@steve.roadcap Yeah I meant LPG, I know you guys like propane.. atleast that's what I learned from King of the Hill :D
@@snap_oversteer I was actually going to refer you to King of the Hill... lol
The reason for the horsepower less is the lack of compression ratio in order to take advantage of the higher-octane rating, just like if want more torque from the engine you need make the intake runner longer just like with long tube header vs short tube header but with more than one cylinder which makes use of exhaust scavenge effect, now as for the cast flywheel it helps maintaining rotating mast which go for torque and lighter billet it aids in faster RPM for horsepower.
@@stingcool9455 you still have to increase the boost if you are using a better fuel

Another good video. This video perfectly illustrates what many competent engine builders know, in that higher octane gas does nothing for more power on a standard engine. I always cringe when I hear people say they put premium fuel in their vehicle so it has more power and better gas mileage . While premium fuels can have some benefits, unless your car requires it or is a built higher compression engine, a vast majority of those benefits are lost in standard engines. Keep up the good work Jimbo!
This is all very good to know. Thank you. 😊
I for one appreciate the frivolousness of using these engines in the car, but that certainly adds to the entertainment value of the project. This is really pretty interesting in all honesty.

Fantastic video!
It’d be really cool to have a dyno harness for the EFI - since those street rolls take a country mile and a half to test - and you could easily stethoscope it to listen for rattles.
I have a twin 212cc drift trike on twin torque converters that could also benefit from a better 3k-6k powerband. The timing keys are a best-guess and I also skipped the billet flywheels because I thought the advance was too much, myself. I have toyed with the idea of demi-turboing it. That’s twin motors, one turba.

Great q&a thanks!!
I estimate there was almost 6.5 ml to maybe 7 ml of ethanol in that gas (7 ml = 5.5 grams of ethanol, added to 20 grams of water, est. 0.95789 g/ml density for that mixture at room temp, so the volume would be 26.6ml, which is about what we see, a little bit over). Not really the biggest deal, but it's easy to underestimate ethanol if you add it to water and measure the volume, because the volumes don't add, the mixture "contracts".
In the current fuel environment, this is very good to know. ⛽⛽⛽👍

If it's the same regulations as where I'm from, E10 stands for "up to 10% Ethanol". And it will vary depending on season and supplier.
It's especially true for E85, they may go as low as 50% during winter to help with starting up the engine.
Learned something again! Thank you :D

This video more or less confirmed a thought of mine that I've had for the past year or so. There was a thread bouncing around on Facebook for awhile where a lot of people were reporting for a few months that they were getting terrible fuel economy. I was one of them...I noticed that from approximately November of 2020 to June of 2021 I averaged only 14.4 MPG in my Ford F-150. With absolutely no change, I randomly began averaging from July of 2021 until October of 2021 17.5 MPG. Then in November of 2021 to March 2022 I went back down to between 14.5-15 with no changes to driving characteristics or modifications to the vehicle. In April of 2022 I went up to 18.2 and even occasionally hitting 19 even MPG. I suspected it had something to do with the E content of the fuel possibly fluctuating and after watching your video, I decided to do exactly that. I took gasoline both 87 and 93 I had in my shed that I purchased in the tail end of February/Early March for my four wheelers and compared it to the fuel I'm getting now and...you're right, even here in Kentucky it seems that prior to April of 2022 the E content of the fuel was for me...between 8-12% but fuel purchased post April of 2022 fluctuated between 4 and 6%. So...I appreciate your video simply because I didn't think about the E content having such a wide gap between consistency.

Your tinkering on this project keeps my tinkering going. Your the reason I keep fabing and building things. Keep it going. I love these videos. Do you do patron? Seems a lot of other people use that to keep unbiased channels rolling that way. Can't wait to see your temps after intercooler install.
Looking forward to another great video from ROBOT CANTINA😊😊😊

Hey Jimbo, ignore the nasty comments from these Mr & Mrs KnowItAll. I am learning the basics from you, its just refreshing.

@@kansasrose2909 What ever happened to the cameraman?
Identical fuels save for octane rating, you lose energy density with higher octanes; higher octanes prevent detonation during compression, so that higher compression ratios, more timing advance, and forced induction may be used. But they're otherwise detrimental, again all other things being considered equal (I did not have any part in producing the fuels you tested)
Also....though ethanol has a lower energy density than gasoline, when burned at stoich, it will make just a little more power than gasoline, and you can advance the timing more to make even more power
Love this video💖

@@kansasrose2909 The first rule of Fight Club?? Have an
ending that can't possibly be predicted.
My best kept secret is the best I've ever had my predator run was when I ran it on white gas(camp stove gas, Naptha)
Made my day!
Here is something that many people do not know about the fuel industry - MID grade gasoline is unusually a blend pulled from both the Premium tank and the Regular tank. The octane rating is a computation of the blend mixed using proportional valves within the dispenser. Very, very, very few fueling stations have an actual Mid-Grade blend in a tank.
This is good information in the current fuel environment.

Using a manifold made up of an array of fined tubes cooled by a peltier may be a compact and cheap solution.
I use 89 "rec fuel" (ethanol free) in all my small engines. Mostly because its still good fuel 2 seasons later. Havent had to clean a carb since i started doing that.
That sounds great. I always like to read the comments on this channel... I always pick up a tid bit or two.
@@kansasrose2909 Me too.

These results make perfect sense. Higher octane fuel is inherently less energy dense. If you don't have an engine that is specifically designed / tuned to run higher octane fuel you're going to get less power from it. The advantage of higher octane fuel is that it can be compressed/heated more before it spontaneously combusts/pregnites. If the engine isn't designed to take advantage of this it's going to make less power then if you use lower octane fuel
This a really good point, considering the fuel environment we are in now. ⛽⛽⛽😜😜😜😜

Great work Sir thank you
Fantastic video!

@@kansasrose2909 Are we going to see more of the ROBOT?
Higher octane doesn’t equal more power. Gasoline of different octane rating will have the same energy per liter/gallon/etc. More ethanol will give you less power bc it has only approximately 60% the energy of gas. Octane rating just means it is less prone to knocking. Meaning you can use it in higher compression or booster engines.
The ethanol by itself is over 110 octane .
Raise the compression ratio to take advantage of that to get the hp back!
The gas / ethanol mix has lower KJ / k g chemical energy so cut down the head or change the piston to get the comp ratio up.

Thanks for sharing👍 yep, the fuel test showed just about exactly what I thought it would. No surprise to me. But the ARC flywheel... surprising! Makes perfect sense but I never thought about the reduced cooling capacity with less fins🤦♂️ almost hate to admit. Also the ridiculous timing advance with the arc flywheel may be adding to the heat generated. Looking forward to the next video!

@@kansasrose2909 What happened to the cameraman??
An adventure is never a waste. You're going extremely tiny on engines, but most people don't notice most cars could actually use a 500cc engine and be able to go up and down the highway perfectly fine. Honestly it would be cool to see some manufacturers making really small displacement four cylinder motors. I say 4 cylinder because the parallel twins kind of vibrate a lot. But a 500cc motorcycle motor has about 60 horsepower. A car going down the highway really only needs between 20 to 40 horsepower. The only issue is it would be pretty slow off the line, but the fuel economy would probably be amazing. Especially if it's running through a 6-speed transmission made for a car. We just like acceleration which is why we need all the displacement.
Such as the Kei cars from Japan? They seem to get by fine with 660cc three pots.
This is why a lot of manufacturers are doing hybrids with a small gas motor. The electric motor produces great low end torque to get the vehicle off the line, then the gas engine takes over from there, as an over simplified description.
@@deanstyles2567 back in the 70s they had some 300 cc kei cars I believe as well(upon looking at Wikipedia kei cars originally were limited to 150cc)
@@91CavGT5 as far as I know most hybrids use the engine as a generator, and solely use the electric motors for propulsion, I do understand there are ones that use both in a propulsion system but they are rare in comparison
@@jaykoerner I just sold a 2018 KIA Niro that could use either the gas engine or the electric motor completely separate from each other, or combined together. The drivetrain that is used in that car is used in other KIA hybrids, as well as some Hyundai hybrids as well. I’m unsure as to what kind of system Toyota and Ford offers since those 2 seem to be some of the largest volume hybrid manufacturers.
I read somewhere that the lowest octane fuel your engine can run on without knocking is going to give you the highest horsepower, since lower octane fuels have a faster flame propagation or something like that.
So many questions; so many trials; so many answers. Still can't walk a mile! lol
Lets see if JIMBO can come up with some answers. JIMBO'S UNIVERSE is like the MARVEL UNIVERSE.
So many twists and turns and trials💥💥💥

@@kansasrose2909 Me too,
Remember that ethanol and water takes up less volume when mixed compared to when separated. That might sqew the result somewhat.
Looking for another great video from this channel.

Ah OK.. so you concluded that a stock flywheel is better or works best for cooling in a confined space.
However, have you considered making an aluminium one and bolting on the stock plastic fan.
I must say found you fuel experiment very interesting..First class..
Me too, This whole endeavor reminds me of the MARVEL UNIVERSE.. so many twists and turns. JIMBO'S UNIVERSE🤓

Hi Jimbo !
Would it be possible to do an engine efficiency test in a future video? I'd be really interesting to see what kind of BSFC (in g/kWh) these engines are capable of. Shouldn't be that difficult to pull off with your dyno and some accurate fuel measurment going in.

Was that 93 sold as e20? If not, that's definitely a big no no for that gas station to be selling that.
Yes it was sold as E20 and it was cheaper than 87 by quite a bit.

Dumb question: would putting some sort of shroud around the flywheel allow you to go beyond 5000rpm? Apart from the flywheel, what would you need to reach high rpm (and wouldn't that be a nice goal for season 7 of the show: reach 7000rpm with a cement mixer engine?)?
This whole build should be featured in Popular Mechanical Magazine.
@@ocdman202 I don't know what Popular Mechanical Magazine is but I concur
@@anidiotinaracingcar4874 The library out here carries it.. They keep
it in a special section of the magazine racks.
Engines of this type are commonly ran at 7K RPM plus for years in the minibike and go kart application. You just need billet parts for safety.

Have had a gardening company for 23 years. Been running 87 octane in everything and chamion semisynthetic 2 stroke oil just fill a 12oz gatorade botttle to the brim dump it in 5 gal gas. Let mix on the drive to the job. Faouled a plug or 2 in 23 years but never burnt up a 2 stroker. I run em WFO
ECU controlled spark advance will give much more power than fixed especially in car application. Fixed advance fine for fixed RPM usage such as cement mixer, car works in wide range of rpm and loads.
