E85 Predator 212cc Build!
Вставка
- Опубліковано 4 жов 2024
- Today we're building a Predator 212cc engine to run on E85! E85 is 85% ethanol, and the right engine specs and tuning, can make a TON of power (way more than the gasoline equivalent in some cases). We're building a stage 2 212 using Go Power Sports parts, including their killer new 265 hot cam. In today's episode, we build the engine, and tune the carburetor to run Sunoco's E85-R properly, and HOLY SMOKES does this engine RIP!
Thanks for Watching!

A turbocharged application would apply nicely to e-85. With all the cooling properties it offers.
Yer on the 750cc honda engine
dont forget the octane
@@williamrheawe958 ethanol/e85 has higher "octane" rating that 93 and is less likeley to detonate
@@einar8019 Yup. e-85 is about 110 octane.
E85 does not double your fuel consumption. My mustang has been on e85 over a year and it consumes around 25% more fuel. Methanol is a completely different story on the other hand.
I run e85 in my built predator, using the same .265 cam. It's a badass combo.
Dude the 265 cam is seriously witchcraft... PERFECT for a yard kart/small track. The E85 is a nice bonus on top😉
@@CarsandCameras it really is the perfect cam. Night and day compared to the mod2. Ive got mine on a doodlebug db30. Its almost too much power. Keeps things interesting though lol!

but what if thru pure incompetence they create the problems that can be completely avoided if knew what their doing Christopher Dwyer? are they fix it hero's? or just stupid for creating problems that shouldn't exist? just asking bud :)

No.... "It'll be Fine" is a sketchy enough of a build logic, it doesn't need to be any worse. LoL

**shows his racing face**
A build like this is where full engine control makes more sense. Instead of drilling jets and everything else you just change a few numbers in a table, plus you get RPM dependent changes to spark advance to take advantage of what E85's lower combustion speed and high resistance to detonation does at low RPM.
Got to say I love what you did with what you had.
You're going to get lower air velocity through the 26mm carb, thus less suction pulling fuel from the carb bowl, so you may actually have to go larger on the main jet than you would otherwise on the 22mm to help 'suction'. Size the carb to your airflow needs. If a 22mm will flow enough air, use the 22 and jet to match the fuel. Going too big will result in poor transition between the pilot and main circuit and the motor will tend to fall on it's face without running a main that's WAY too fat for what the motor really needs.
Should run 2mm smaller then the intake port size to get enough vacuum.
Not enough for less signal in the carburetor, Port velocity in the head is the main concern unless the carburetor in question was a 30-40mm or bigger
@Garrett Knowledge is never a waste of time, watch this: LOL, a ton more ton more power, hahahahah, I love you guys. I am a retired dyno-tech, that only thing E85 is good good for is stability between weekend's in 1/8 and 1/4 miles cars as oxygenated fuels are less sensitive to weather conditions....Nitro-methane being one of the few exceptions, and corrosion in engine components. Don't get me wrong, it's like many of my younger friends, you never listen, and it is fun it is watching you try things. I would heed the MSD sheets on the stuff thou, and don't that stuff in a hot shed, that is not a "it will be ve fine" circumstance. The bump in compression was the best mod you made. BTW less mass on the flywheel is for better engine acceleration , not power. If you do try tuning with an 02 sensor, note that you will find best power around 9.87 afrs @wot, in my testing anyway, and i do not care where it is with pump E85. Get the actual fuel specific gravity from Sunoco, as it changes per batch
@Garrett Sadly few of my comments even get approved unless i just praise them, i think they i am just a arrogant knowitall, which i am not, i am a fan, and old dynotech, i just wanna help, and i realize knowledge is gained through experience. I just try to help, not criticise. Perhaps my wording suk
@Garrett Also could be the books i post exceed the 608 word thing and i fall in the troll bin, lol
I started binging this channel and decided to revive my old go kart which has been sitting in my garage for years. Picked up a predator 212 and it runs like a champ. The gas pedal would get stuck down but I decided it’ll be fine and just reached down and used the gas pedal with my hand
Matt Lemunyon 👍🎉👏🏻👏🏻👏🏻
Do an alcohol build. I ran jr dragsters for a few years, and we ran all billet alcohol engines. Tons of power to run 7.90 in the 1/8th mile, and a crazy sound from a 3 1/2 bore.
OJD1902 that’s not very fast. But jr dragster motors are powerful but they are slow
Ryan 14R yes it is, that is the fasted you can go in the jr with out getting in trouble where I live
This dude stupid. 7.90 would out run almost any street car and out mph. Dude thinks his dirt car be busting 4.90s 1/8 mile 😂
@@WilliamsMotorsports1x80 you’re the stupid one. Did you even read his comment! He said 7.90 on the 1/8th mile
If you can try and advance the timing. E85 is not as knock limited as reg. fuel. Also by advancing the timing you will have a lot cooler exhaust temps,and will do wonders for the torque curve
+1 on this statement.
Hell yea exactly what I was thinking! Even though the flywheel is already advanced it could possibly go further with the e85!🤘😎🤘
John may not be much of a driver, but he is a walking shop manual for almost all motors and after market parts -- he is so impressive and and there isn't anything Issac can't do with a motor to make it fire, turn over and run -- he wows me on every video
Liked watching the build... You guys are always thinking out of the box... Seems there's never a mechanical problem you guys can't solve... Thanks for sharing.... I'm a new subscriber and your channel has influenced this 53 year old kid to go buy a mini bike, ride it a while, then start tweaking it... I used to be a diesel tech, so I have some knowledge, but I'm picking up on these small engine builds by watching you guys.... Thanks for sharing... I really enjoy your content....
Why dont you guys get a a bunch of jets to keep in the garage? It would be way better than drilling them out
Dakota Schmitz.. apparently you haven't realized that pre planning is frowned upon in the cars and cameras garage.
@@jq71 I see that
Or, DUH! just use the "high altitude" jet that COMES/W the engine....!
Waste of money and original parts when you can efficiently mod the original.
Ooo the truck has a bed and rad support. That's minty.
The more compression you run the better the gain from E85. True pump E85 is around 110 octane
I just want to thank you guys for inspiring me to get back in to gokarting. I just bought a kart for my son. Puting a hemi 212 pred on there now and a TAV from go power sports. Its going on a 1970s live axle set up. Thank you very much.
I couldn't find "pre-used" on Wikipedia, so I petitioned to have it added in ur honor...
Thank u guys for this build cause I so want to buy a cheap go cart, and do a build like this
That kart sounded nasty af. Keep up the vids.
"I'm going to snap my fingers..." Ad...
Aww man.
Funny the sunoco blurb didn't say anything about e85 having 25% lower energy density than gasoline.... If you're particular setup can safely run gasoline it WILL have less power on e85. Don't get me wrong e85 allows for boost and timing levels that gasoline wouldn't in certain applications but you cant just throw it in a setup that works on gas and get more power.
Anyone who races anything should know you need alot more alochol than gasoline in the same engine, thats why it has the cooling properties it has.
@@16driver16 yeah but there are a lot of people who don't understand why high performance vehicles use the fuels they do and just assume it'll make them faster too because Race Fuel!!
@@DoRC do they think if they put jet fuel in their car it'll fly like on family guy too?
Do RC All things being equal, and you change over to e85, e85 will make more power than just about any gasoline aside from maybe Q16. Yes alcohols have less energy density, thats true for both ethanol and methanol. E85 improves power and torque production under the curves and peak power numbers as well. In this application, if the carb is set up properly, it will out power the same engine on gas. E85 not only has an octane advantage, it also has to advantage of latent heat vaporization that gasoline does not. It’s a very forgiving fuel, and it makes better power and torque than gasoline
@@taylorgtrotter So you're saying that switching to e85 while making no other changes will produce more power? How is that possible? How can using the same amount of a less energy dense fuel produce more power?
Im pretty sure you just threw off the crank balance by grinding on it.
It'll be fine
I’m pretty sure it was already going to be off when they put a lighter connecting rod on it.
lol no.
Itll be fine
Small engines are not balanced all that well to begin with. I was a Kohler service trainer for years.
John: "We're waiting on parts for the cross kart"..
Me: "Nitrous!!! Its gotta be nitrous.. Get you a freedom button on that thing"...😂😂😂🇺🇸🇺🇸🇺🇸
Sounds like you're a fan of the cleeter 😂😂👌👌
@@theshit683 Honestly, I've only seen a handful of his videos. But, I am a fan horsepower and tire smoke.. Because, 'Merica..😂😂
The Shit just get James to spray😂🤟🏻
Bawg deep!
Calm down there cleeter, in time, in time.
The power potential can be calculated:
A richer stoichometric air fuel ratio of 9/1 for ethanol allows more fuel to be burned in a single stroke vs gasoline's air fuel ratio of 14.7/1.
This is party offset by a smaller energy content of 22,7MJ/L on ethanol vs 32,5MJ/L on gasoline.
This is overall a 14% power increase if done right.
E85 tends to cool the intake charge by evaporative cooling, which is not too important on an naturally aspirated engine, but can give a small power increase due to a denser intake charge.
The last factor is the higher octane rating of ethanol, which doesn't give ANY power increase at all to a unmodified engine.
It is very important to note that even on an engine with raised compression, there is zero gain from a higher octane rating. It is only interesting and will give a power increase over gasoline, because you can increase the compression ratio PAST the point where gasoline would start knocking and not be able to run in this engine.
You'll probably not feel the power increase, since 14% is well within the margin of error that your jetting will give you. Still, it's a 14% power increase, given that the jetting is set correctly on gas and ethanol.
I love the cross kart, but this was an awesome change of pace for me- with EPIC results. Now that we know that it works, we're going to:
1. Compare E85 R to an identical engine running on gasoline
2. Build a stage 4+ 212 (making over 20hp) and tune it to run on E85 to see what kind of gains we see😈

Nice build John and Ike! And John i noticed that the C10 finally has the bed for it. Keep on building and testing these awesome builds guys!
i got something to say i have a old go kart that i want to repair so i been watching a lot of videos about go karts then i found this channel and its help me a lot so thank you
E85 smells oh so nice. Going E85 makes you a believer, I just wish I had it locally since I moved away from my local pump.
I thank goodness I don't have it locally... Why do I need to build for another fuel? It's only going to take infrastructure away from the superior gasoline that's already out there.
It so fun watching you and polite Isaac
Liking the video before it starts because E85 is the best!!!👍👍👍
For a minute, I thought you fast forwarded the video but no, the cart is just that dang fast with the stage 2! Love it!
i love the suicide shift go kart its my favorite
I'm amazed just how fast that go-cart accelerates !!!!! Watching this video inspired me to build one!!!
Nice backyard job guys,BTW John your truck is looking great! how about a built update please?
Tony from Western Australia
I was to busy to watch this yesterday and then today I finished work early due to the weather being to hot in ENGLAND!! 😂 which does not happen very often lol and then I got back to a lovely 22 minute video 😍😂
Your going to need big compression to make the most of that corn liquior. 13-1 to 14-1 . propane is also realy high octain but realy drops your power against gas because the compression ratio needs bumped up big time to take advantage of the octain. You going to need to get the head welded up to take advantage.
I run E-85 in my Banshee and have found that 20 main jet sizes gets you in the ball park..I went from a 140 on 91 to a 160 on E-85, opening up the hole in the float valve boss really helped as well.
Am I the only one that sees the striking resemblance to Ricky Bobby
Been running my small engines on e85 for 2 years including my mower and my mustang has been on it for over a year also. Small engines all you need to do is drill the jet out a few sizes. Quick valve spring tool - take a socket and shove a tight fit piece of a magnet up inside it.
5:25 Should we try it? I don't think so dude...wham 🤣 You guys are great.
More 212 action....wow so much new content.
I just rewatched Drag Mini Bike vs 670cc "Black Widow" What ever came of the filmed naked lap?
you can pre check cam clearance by leaving the rod and pistion out and only install the cam, rod and crank shaft, and i hope you are properly torqing the side cover bolts, and using red loctite on them.
Issac looks like he was the biggest Limp Bizket fan in the 90's
Have you guys ever considered adding a wide band kit for tuning AEM makes a real easy to use, and the results of a properly tuned engine will blow your mind. I have a feeling you guys leave a lot of power on the table.
Have you ever considered buying a jet kit
Have they not done this before?
@@16driver16 lol drilling jets is the first things they do whenever something doesnt run right
@@bcouri1 thats what i thought, they ARE the jet kit.
@@16driver16 Drilling jets is NOT the same as buying actual jets in the correct sizes. Think of it this way, you can "decap" 700cc fuel injectors and get ghetto flowing 900cc injectors with bad fuel atomization and spray patterns. Drilling jets is exactly that. You can drill a size 45 jet to a 50, BUT it will not flow or atomize fuel like an actual precision machine tapered, chamfered and cut #50 jet. Sometimes the difference can be as big as a few HP. I saw a 12 HP increase on my 95 cb750 when using real jets vs drilled ones, both the same size.
@@losi8ightyew that may be true on a larger carb like on your 750, but on a carb this small, im not convinced
That engine sounds AMAZING
I mean that cart is god looking verk fast and just awsome. I realy love karts But i dont have one😢 if somebody have a engine can i get it?.?? That engine sounds amasing
Fun project.
More compression. More ignition advance. Larger diameter carb to allow the larger volume of fuel per charge to atomize. 24mm is a good start. Jet to compensate and don’t neglect the fuel pump, float level or inlet needle.
Is that carb e85 compatible? That's a drum brake hold down spring tool lol
A few things about E85...pump E85 can be a blend as low as E50 depending on the time of year. High percentage ethanol gets really tricky to start in the winter. If you run anything on pump E85, you should have a fuel composition sensor with blend tables for EFI, or a box of carb jets, because E50 in the cold months is not going to jet the same way as actual E85...one benefit of buying it in a Sunoco can if the above mentioned is a problem...it's consistent. 2nd, E85 tends to burn a tad slower, so a little more advance is needed as a baseline. E85 has a very high anti knock index compared to any pump gasoline, so there is a good chance that you will be able to advance timing beyond peak torque safely and will more likely not be knock limited anywhere in the map on a naturally aspirated engine, allowing you to realize full power potential in more operating conditions (especially against heat soak). E85 also makes rich best torque about 11:1 AFR on the gasoline lambda conversion scale (gasoline is more like 12:1), so it does make best power a little richer relative to gasoline's optimal AFR. E85 evaporates more easily and so provides more of an intake charge cooling effect. It also burns cooler, so your EGTs should be lower at optimal mixture than gasoline. And of course the thing that drives me crazy...E85 does not decrease fuel "economy"! It decreases fuel "mileage". A well tuned E85 setup will about break even in cost per mile on road with midgrade pump gas, but with far superior performance and longevity benefits. It burns much cleaner, so carbon buildup is much less of an issue. The only thing to be aware of is the moisture and resulting corrosion issues, so don't store it for a long time, keep car tanks topped off if it's going to sit more than a week, do not leave fuel in the tank or fuel system at all if the system is atmospheric vented or has problems with the evporative recovery system leaking. Have fun!
Make sure to turn off the fuel and run the carb dry after running.
Cory Unferferth its not methanol, you don’t have to do that with E85.
@@taylorgtrotter the ethanol will destroy rubber seals in the carb...like rubber on the float needle that fits into the seat to stop gas from entering the bowl.
Cory Unferferth ethanol doesn’t eat modern rubber components. Natural rubber in older engines? Sure. New engines? No...unless it is left exposed to the elements so it can absorb water. Easy fix, close off the fuel system from both ends while it sits or run it once a week and let it get up to peak running temp before shitting it off. That pretty much takes care of 90% of the common issues
nice build guys. im liking it.
Please please please methanol carb for the rat rod wagon! 5hp briggs on methanol have soo much more power than gas. Should be able to get fuel from the same company.
They even have a racing carb meant formethanol from the parts lot shown ages ago. Just gotta get it going!
@@nap8187 awesome, actual alcohol carbs have HUGE jets that wont run right on gas, they usually even dont have chokes because they are an air restriction. My friend has a 5hp briggs kart, it had a fully built engine, cammed, ported, aluminum flywheel all that and a methanol carb and it was seriously fast. He blew a hole in the side of it and i gave him my stock low hr bottom end and all he did was put the meth carb and gas tank on it and it was somehow almost as fast as the fully built racing engine
I love the gnarly sound it makes.
Oh Boi grinding on the crank, that should be rebalanced. It'll be fine huh
Fantaman900 it’s not a race car precision machine it’s a toy if it breaks it’s beaks who cares
Couple mil off the crank? Meh. Not like the rotating assembly was balanced anyway...
These engines are balanced about as close as trying to level out a 12'x12' floor with a 6inch level. Not real precise .
Any time I remove a governor I remove the sprocket for the governor.
It removes a few more ounces of rotating mass allowing the engine to spool up faster.
You can also grind off the casting Mark's off the crank, rod, piston, and cam plus drill more holes in the piston where the oil rings go to add lubrication.
Also remove any burrs or sharp edges in your oil ports in your rod where your bearings go.
Do it on a 420 even better 670
"we got some red lock tight, YEAAAA."
Great build!👍
Nice to see a small engine e85 build! Over here in sweden we have "moped dragracing" and many racers use e85 fuel in their 50 or 70cc twostroke engines👍
you can look at your spark plug and see if it looks lean or rich also
YES!!! I’ve been waiting for someone to do that for soooo long!
Y'all should come to the th smokies
The only way you really see any gains with E85 is if you are running super high (like 14:1) compression or boost. In a low compression N/A carbed engine you aren't going to see much change other than it will run a little cooler. The benefits of running alcohol is it's more stable at higher cylinder pressures than gasoline. You need 30% more fuel over the base amount of any given size carb. Going up to a larger carb with more air doesn't mean you need less than 30% more fuel, you need 30% more fuel than typical with that amount of air. It's the air fuel ratio that matters, with more air from the bigger carb you still need 30% more fuel for it.
BTW there's also different octane ratings of E85.. just because it's 85% ethanol doesn't mean they octane number is the same.. Watch Engine Masters on MotorTrend On Demand.. Freiburger did a thing where he showed the difference between E85 and high octane race gas and had multiple octane levels of E85.
I been waiting for this
A better comparison would have been if you guys completely rebuilt the engine with the stage two parts then ran it on the 95 octane fuel got a TopSpeed number and other real world data then began drilling Jests for e85. I would look into some sort of slip on air fuel ratio gauge for tuning as well
Does grinding the crank and cam not throw the balance? Trucks looking good in the background too
It's a Chinese single cylinder
Yea i think it will
Nick Brogdon my next question was gonna be how did the manufacturer expect it to fit without modifying it haha
As a matter of fact I removed the balance shaft from my GX270 years ago without an issue... Could be luck idk
Nick Brogdon I’ve never fooled with them I’ve just worked at machine shops that build dirt track motors mostly sbc bbc Ls stuff so that was new to me
Nice first time I can remember someone doing this
Love the vids keep it up
It RIPS in a shaved head 2 stroke. (just use a good racing castor like Maxima 927 or Klotz) Also, you're going to get the full monty 85% during the summer months, especially down south. It's during colder weather that they blend it more towards gasoline because it does NOT like the cold. In the winter, I need R/C car 30% nitro (basically as a starting fluid) to get an E85 2 stroke to run at all.
Good call going with the Stepside bed John. Sexiest trucks ever!
You guys really keep bringing great unique content.

You guys need an engine testing cart. Just something like a work cart on wheels to mount engines to and test them.
Stop playing around with the E85 and get some M5 methanol...😁 make sure you add some top end lube with M5
isn't methanol poisonous?
@@Charlieswag9000 yes it is. Its what you cut out when you distill booze.

@@PullerbearEd "methanol (whether it enters the body by ingestion, inhalation, or absorption through the skin) can be fatal due to its CNS depressant properties"
Way to support the farmers!
E 85 with turbo... Send it.
The timing advance is going to give a good bit more power even without e85. The ethanol allows it to run more Compression and timing without detonation , it also as you read, helps cool everything including the Piston crown which also helps resist detonation. So the reason you get a bigger gain with a more modified engine is you can get more aggressive with the tune without detonation and it is assisting the cooling system too. You definitely want to err on the rich side, you can cook it pretty quick. If it's popping on deceleration alot I would richen a bit.
It takes more e85 than normal gasoline in the case of it being lean
Yeah.. They kept telling us that throughout the entire video....
FYI, for everyone out there, do not use the hole for the governor arm as the crankcase vent. There is a reason why Honda designed the crankcase to vent out the head cover, because the high pressure air, laden with oil droplets, would make its way up to the the valves and rockers before venting. Without pressurized oil lubrication, this is the only way to insure oil flow to the valves.
E95 Racing fuel🤣. 95octan is worst what you can buy in Finland and in most Europe. Sales of 92octan stopped in late 1980s
E85 is 85% ethanol which would be around 101 octane, USA Octane rating is also different to what you use in Europe, google it and see
the 93 is the same as our 98;)
Aki look it up
Well I really like the videos and that go-kart to me look like it was cranking it out looking forward to the comparison to the regular gasoline engine
thats a tillotson not a predator 212
lukas stipp they start with the tillotson and tear it down and figure out that the predator kit wont so they tear down a hemi predator and thats what they rebuild and is on the cart.
@@rileyfenley522 ya i know but its kinda funny when u see the title, and then the first shot is of a tillotson 212
You should put an arc variable timeing flywheel with the e85 so you can advance the timeing alittle.

Yay Isaac!👍
Man you snuck in there.
great work guys, now lets see how it does against some of your other projects
LOL - "34 degrees advanced?"???!!!! does it say THREE POINT FOUR? 34 degrees advanced timing isnt a thing-
That "Valve spring compressor tool" looks just like the drum brake tool I have
All the timing. +34°
yes, that is correct. 34 degrees advanced. The magnet on the flywheel is 34 degrees ahead of TDC
There isnt much to risk on the higher power motors. It actually if anything protects the motor IF the internals are strong enough for the power. It cuts down on knock and keeps the motor cool further lowering knock. Just need to make sure fueling is there because it requires more about 30 percent more. We use it on all the turbo cars because of it. It's basically cheap race ruel. Pick it up for cheaper than gas in the area (still spend a tad more based on mpg), far cheaper than the comparable 110 that sells for about 8 bucks a gallon in my area.
I wanna see a max hp build it can be higher then this c'mon guys
That motor is gonna be properly balanced now. SARCASM
Second comment 💯
The compression needs to be bumped up 12.5:1 or higher. The more heat you pump into the combustion chamber the better. Fuel/air mix & heat is the base rules for alcohol engines. That's on top of rpm. Make it breath freely and pump in the fuel. That's the secret of E-85 fuel engines. Be extremely careful alcohol fires are invisible Or damn close to it.
hell yeah this thing is insane
Some of the points that are good here, the 22mm carb might be better for the air velocity. As long as it can feed the motor. Also a bigger carb may have a bigger jet, but it is still sized for gas, you will still have needed a bigger jet which you learned. Also timing may be an issue. Alcohol burns slower, so more advance is needed.
This channel really makes me wish I knew more about mechanics.
You can always learn, the beauty of YT is that there folks that are posting vids on just about everything including simple breakdowns on mechanics. These kinds of builds and go karts in general are incredibly simple machines and if you tear into one to learn and destroy it somehow, your only out a hundred bucks. I learned how to work on stuff by taking apart and reassembling the family lawn mower and weed eater when I was a kid and the stuff I tore part and rebuilt just got bigger the older I got. It's not hard and anyone with just normal intellegence can learn it.
I'm sure someone probably blow has commented but yes you have to use a lot more e85 vs. Regular traditional fuel.... the other thing is alcohol also has a different flashpoint which means that timing may be a consideration.... Flashpoint is basically when the fuel is able to ignite due to heat
