@@davecrupel2817 the power output to weight of this is pretty bad. It makes about 4.3hp, a good competition 3.5cc 2 stroke makes 2.5hp+ weighing a fraction as much, and a decent 28cc 2 stroke gas engine will make over 5hp easily. This is definitely cool, but it won't make a car fast at all.
@@EAGLINWRX Or less! The fuel tank would have to be much larger and weigh more than the rest of the entire RC vehicle altogether! But then again this is an extremely high RPM! You would need some type of two or maybe even three speed automatic transmission to be feasible!

That's a great question, I think the same things sometimes because they're so small but this one is supposed to be 4.5 horsepower, I absolutely have to test that in an upcoming video
For temp issue, you should bleed the cooling system better. Too much bubbles in the lines. At least is the first thing I thought. Engine could use some air too, listening to it.😊👊🏻
That's not the main issue at all here...The reason for all the heat in the block is...is he let it run at absolute max throttle knocking its nuts off for a prolonged time till the fuel tank was completely empty, did not let it idle at all. The result is that the water pump is driven by the belt on the front, no engine RPM = NO coolant flow! hence the lines being hot close to the engine. completely the wrong way to look after an engine.
@@motographics The engine can't cool with air in the system. The engine at max ROM should be flowing like hell with coolant but it wasnt. Either there is air in the system or it's cavitating or both. High RPM does not matter the cooling system should be able to keep up just like any other engine in a car etc. If it can its poorly design or has issues.
It looks like the source of the 50:50 air:coolant going into the engine is the hose exiting the overflow tank close to the water level. It's not really an overflow tank if it's directly within the path of the circulating coolant...
@@cenreaper3221 Maybe you misinterpreted my comment, but I never said this engine was double over-head cam, I said it was a possible future improvement for this engine, by Toyan themselves, while answering FAQs. They mentioned possibly supercharging it, making a petrol version, and making it an actual DOHC.
Still waiting on the boys over at Donut media to release that second video. Just left this little engine alone, utterly defeated. I'd love to see someone slam it in an RC.
This! The crankshaft moved by pistons alone is such a weird concept, especially with the way the pistons move asynchronously. From a first glance, it doesn't look like it should work as it does, it's so counter-intuitive. And we perfected these things to the degree that they can be mass produced.
was it firing on all cylinders? and maybe it was intake choked? there must be a restriction not letting it rev higher! id love to see that thing on a dyno also :D
i wouldn't want to rev it much higher then 10k plob would start to melt after awhile even with the cooling that why most run away engines stop running they can hit higher then 10k rpm but the stress on the metal and the heat is too much and they break apart
There are so many things wrong with that engine... Cooling, 'oil', intake, fueling, valvetrain (I'm sure it's not sealing properly), it's unlikely to have optimal spark for that engine (even though that's one of the easiest parts),
I’m quite surprised that you run this engine without any oil lubrication at all! But I suppose the grease is enough to suffice! Excellent video! I’m a retired ASE Certified Master Automotive Technician, and I’m just getting into building these tiny automotive combustion engines and I’m loving it. I diagnoses, repaired, built, rebuilt and restored my own vehicles and others cars of course. I’m disabled now but really enjoy these as a hobby. I have some really cool steam engine four bangers, rotary even a couple of small Buick nailhead engines like my big ones. These are a blast (Pun intended)!!!
@@christiansanden8005 Agreed! Far too much heat for too long will easily blow a piston or valve and much more!!! I wouldn’t run them longer than a few minutes so it’s a good thing the fuel tank is so small!!! When putting mine together I lubricated the short block with some Q tips dipped lightly in Royal Purple that I use in my cars and trucks. This at least gives it a bit of a coating. After some thought I decided to use a five weight that I run in my turbocharged four banger performance engines. I felt anything more would result in hydrostatic failure of the lower engine internals because of the micro tolerances in theses mini monsters. As far as the Cylinder Heads, Valves and pistons Rings are concerned they should be well lubricated fine for the first three to five minutes from the grease. It will melt quickly and coat well! But anymore than four or five minutes I would probably suggest checking it once the entire engine has been given a chance to cool before taking off anything more than the Valve Covers! But if you’re anything like me, that’s just part of the fun!!!! How I’d love to stuff this engine into a die cast car with remote control steering and throttle control. That thing would SCREAM!!!! It would be great to terrorize the mice in the barn with! 😂😂
@@ManicMechanic82 Yeah that V8 would be cool in a rc car but without a real lubrication no way, also the consumation is quite high so it would need a huge gastank, i have several rc cars, one with a 2 stroke OS MAX, running fantastic. Kind of weired that this baby V8 are so expensive and without a proper lubrication, no way to run it long time
I'm a big RC plane dude and I would absolutely love to see this in something like a scale Spitfire, P-40 Warhawk or Mustang! That would just be absolutely incredible! I know that a lot of those planes in real life were either radial engines or straights but this would look absolutely amazing and an RC aircraft!
@John Connor I ment just the idea and visual of it. But yes... It has a long way to go before it will catch up to other 4 strokes in the industry like Saito and O.S.
Excellent. Sounds great! Just one thing, where’s the oil? Didn’t see you put any in, yet it dribbles out of oil seal. Also, camshafts etc lubed with grease! Never seen that before!
It really isn't, as long as the carb is sized for the flow rates; I used to run 1.5 (0.09CI) glow (methanol) engines and it was easy to get the fuel mixture right from idle to flat out.
Excellent video! Because it blows fuel and oil out of the exhaust, it would be wicked cool to put top fuel like exhaust on it! Maybe even make a rc dragster!
Hell it sounded like a proper v8 before the muffler cut. Deep throaty sound, and amazing when you hit the throttle. With everything removed sound like an RC boat.
FYI, there's a possibility that you'll break one of those exhaust valves if you run this engine for an extended period of time without an exhaust system especially at high RPM. That's why I recommended running zoomies to get the sound you want. Under "real world" circumstances, an exhaust system is there to provide the proper back pressure to enable scavenging of the spent exhaust gases. An exhaust system will also isolate the exhaust valves from being overexposed to O2, which will eventually oxidize them and crystallize their metal composite, making them potentially brittle. You could even put small balls into the ends of the zoomies to prevent water condensation from entering them during or after cool down.
Thanks! Those are really great details, those are things not many people think about but you're absolutely correct. For sure I am going to make a proper exhaust, I just ran it without the exhaust to see if it can actually get louder or is it like an engine Port size issue... Thanks !
@@Mrshotshell You obviously don't understand the concept. There's a reason every engine has an exhaust system and it has nothing to do with back pressure or noise. An exhaust system, whether it's zoomies (which effectively produces little or no back pressure) or otherwise, is not just there to direct exhaust gas to be dumped out at some point rear of the driver. From an engine perspective (all other issues aside) an exhaust system is ideally designed to "tune" the air flow as it travels through the engine (particularly in an engine with normal induction), and while doing so, provides a certain level of protection to the exhaust valves from being exposed to ambient air, which will ultimately weaken or fatigue the alloys in the metal.
@@frankhamilton8257 My understanding is that the issue with no headers and the valves is thermal shock, i.e. cold air hitting the 800+ degrees C valve cools it very rapidly, over time this can cause cracks to grow in the valve until it breaks. Should not be a serious issue for such a small motor, smaller valves generally don't get as hot because they have more area to conduct heat to the head relative to the amount of heat they absorb. Also glowmotors run on methanol with a hefty dose of oil (usually 20% or so), which naturally burns a lot cooler than gasoline. More broadly, I suspect that this is an engine specific issue. Many WW2 fighters had 'stub' exhausts, the 'header' if you can call it that was no more than a short nozzle that directed the exhaust flow backwards as it came out of the ports on each cylinder (for bonus jet thrust!). These would surely be candidates for the thermal shocking issue, but on the contrary most of them had more trouble with burnt valves than cracked ones, leading to the use of sodium cooled valves, stellite valve seats, etc.
@@allentoyokawa9068 Unfortunately at the moment you can only count on this chinese brand, as a consumer I do not care where it is produced, not to mention that most people are tired of this cliché, you like weeb so much should know how the evaluation of japanese products in the last century is rising, now you criticize chinese goods are just like the pot calling the kettle black.
Been a while since I wrenched, but sounds & looks like advancing the timing a bit, if possible, would help at the higher end. It was spitting a ton of fuel after you clipped the headers, so you reduced the back pressure to force secondary burn. Maybe a slight tweak of advancement would allow a more complete burn.
I believe that extra fuel is caster oil and is how the engine gets it's lubricant into the cylinders. Usually these engines are glow plugs and are designed to already run advanced. Hence the nitro / caster oil mixture in the fuel.
I was thinking the same as the other guys have mentioned-there's no advance and retard on a glow plug engine but I'm sure I've seen another vid with this v8 and he had timed spark plugs (JohnyQ90 I think)- I guess with the programmable tech you can buy (Arduino Etc) you could make a proper mini ECU these days too. All the best.
Try putting more fuel pressure so the fuel comes more fluently so it can run better and try adding a transmission and a body so later you can add it to a car
It would be awesome to see these in a chassis! As a nitro RC. There are kits available and wouldn't be too hard to put this in 👀 Perhaps you could even make a mini Supra modeled after yours
Save your $1,700. This thing overheated when it wasn't doing anything more taxing than spinning its own flywheel because the cooling system is woefully inadequate, it can't breathe, it didn't even live up to the 12,500RPM promises in the pre-release marketing spiel, and it clearly has issues with staying running at lower speeds.
@@AndrewMalkin It should self bleed without any issue. The fact that it didn't, combined with the fact that the radiator was still pretty much room temperature while the engine was screaming hot, tells me the water pump, cooling passages, pipework, et-al is just not up to task.
This made me think of a really cool idea. Build a rc car around this engine, with a transmission if possible. Hook it up to a PC racing simulator. Drift around a parking lot, or make a racetrack. I could see it becoming a new motorsport. Welcome everybody to the Warped 100.
I've been totally thinking about that for a long time now... And it's so crazy that you said that because I literally in the last 4 months pulled together all the components to make that happen in a video... We think the same! That's nice
I'm thinking at 28cc it might be able to power a super lightweight go-kart... obviously only to about 2 mph but it theoretically might be able to do it with enough gearing advantage...
Collector's merged into an x-pipe to duals would sound the best imo, you'll pick up some scavenging and drastically improve the sound. Either that or headers merged into a single large pipe.
@@WarpedYT yep, I see a lot of comments about back pressure being needed, it's simple not true, you do need some length for the header to keep the valves living. The back pressure argument has been disproven many times I've read that in the comments quite a bit. As drag racer it's simple not true, any back pressure will hurt power if the exhaust is designed efficiently to scavenge.
It's misfiring badly... When you have so many cylinders, you need a proper ignition system. This engine needs real sparkplugs and an Electronic Ignition System to create organized firing inside the cylinders.. It's a shame they did in Nitro intead of pump gas. No oil pump either. Improvements need to be done here.
@@eljaibas16 I wouldn't have approved such a crappy engine system to be taken to production... I mean, how is this supposed to compete against a brushless motor.. let's not even talk about price differences.. a premium brushless motor is about $200 bucks.. 8 times cheaper, and 20 times cleaner. This engine needs: *Proper Ignition System with coil box *Real sparkplugs *Crankshaft position sensor linked to ignition computer to tell the sparkplugs when to fire. *Oil pump to bring oil to the head. *Piston Ring sets to increase compression and something extra but really nice: *a hydraulic torque converter to be able to use combustion rc engines in rock crawlers... centrifugal clutches suck at low rpms.
@@P_double_H Agree, for that kind of money it should have a real ignition and lubrication system, expensive toy beside it takes a lot of fuel, awesome tough
You should open up design and fabrication school and people will line up. Your videos are a joy for us simpleton that still use an angle grinder and a drill to fabrics parts.
This is really cool. However it blows my mind that there is enough demand for these to sustain a business, even though you can buy a REAL engine for much less. Still very cool.
While this V8 engine is small it is by no means the smallest. If you visit the Craftsmanship Museum in Carlsbad, CA you can see V8s that are quite a bit smaller as well as V12 engines that are also smaller.
Year's ago there was a guy building Supercharged OHV V-8 engines. His name was Gary Conley, of Conley Precision. He built a Dragster and a Shelby Cobra equipped with one of his engines. They put out 10hp! His shop caught on fire and I think he quit. I think there's some UA-cam videos out there. One guy built a Grave Digger Monster Truck, another, a V Drive Off Shore racing boat, that had 4 Supercharged Conley V-8's! Super cool stuff.
Wow, a drill the size of a V8. That's impressive!

It won’t turn the idle down , it will just make it accelerate slower but have more momentum when starting to move
@@type2523 the flywheel itself won't lower the idle, but the added mass makes it less likely to stall at low rpm.

It sounds like Its choking, do you think it's getting enough air? It sounds good though, and looks awesome!
Not enough air at all.
It is a chinese branded product, don't expect much
@@allentoyokawa9068 Unfortunately at the moment you can only count on this chinese brand, as a consumer I do not care where it is produced, not to mention that most people are tired of this cliché, you like weeb so much should know how the evaluation of japanese products in the last century is rising, now you criticize chinese goods are just like the pot calling the kettle black.
I'm going to watch all your Videos
who’s here after seeing Donut Media’s video to see the engine running?
Yep
imagine engineering a small supercharger to it lol
Been a while since I wrenched, but sounds & looks like advancing the timing a bit, if possible, would help at the higher end. It was spitting a ton of fuel after you clipped the headers, so you reduced the back pressure to force secondary burn. Maybe a slight tweak of advancement would allow a more complete burn.
I believe that extra fuel is caster oil and is how the engine gets it's lubricant into the cylinders. Usually these engines are glow plugs and are designed to already run advanced. Hence the nitro / caster oil mixture in the fuel.
You guys are speaking a different language and I love it
It's a glow engine, so it has no ignition timing as such.
I was thinking the same as the other guys have mentioned-there's no advance and retard on a glow plug engine but I'm sure I've seen another vid with this v8 and he had timed spark plugs (JohnyQ90 I think)- I guess with the programmable tech you can buy (Arduino Etc) you could make a proper mini ECU these days too. All the best.
Man! That little monster is cool beans!
Whos here cause of DONUT ?!?
It is absolutely amazing with the technology of today what can be done in engines especially for hobby shops they've come such a long way
That was soooo cooool !!!!!!! I love these scaled-down engines, they're just mesmerizing to watch! Thanks for the great video!
Music for sure! Very cool engine.
how hard would it be to connect this to a automatic transmission lol, would make a epic RC car
It would probably need a fuel tank bigger than the car itself if you want to enjoy it long enough
@@Jonathan-qi9rh Yeah it seems to be that it takes a lot of fuel just like the real V8 does, LOL
That thing is adorable!
still @DonutMedia was unable to build it
Try putting more fuel pressure so the fuel comes more fluently so it can run better and try adding a transmission and a body so later you can add it to a car
You are ridiculously talented! What a freakin knowledge of motors and machining you possess that is admirable
I think that's why he gets these motors -- as an excuse to build test jigs to exercise his machining skills!
Every 90s/00s game publisher: DANG IT THEY FOUND OUR SECRET V8 ENGINE NOISE SOURCE
Remove the air filter, put twin turbos, and slap a tank of NOS lol 😂😂😂
Quick someone tag Donut Media!
It would be awesome to see these in a chassis! As a nitro RC. There are kits available and wouldn't be too hard to put this in 👀
Perhaps you could even make a mini Supra modeled after yours
Save your $1,700. This thing overheated when it wasn't doing anything more taxing than spinning its own flywheel because the cooling system is woefully inadequate, it can't breathe, it didn't even live up to the 12,500RPM promises in the pre-release marketing spiel, and it clearly has issues with staying running at lower speeds.
@@TestECull His coolant had tons of bubbles. It's hard to tell how well it cools when it wasn't bled well.
@@AndrewMalkin It should self bleed without any issue. The fact that it didn't, combined with the fact that the radiator was still pretty much room temperature while the engine was screaming hot, tells me the water pump, cooling passages, pipework, et-al is just not up to task.
JohnnyQ90 runs a couple of these small engines on his rcs
@@TestECull I think the hoses were waaaaaay to long. Imagine putting that amount on a vehicle. It’ll do the same
Definitely music in my ears 🎵 👂🤗
This made me think of a really cool idea. Build a rc car around this engine, with a transmission if possible. Hook it up to a PC racing simulator. Drift around a parking lot, or make a racetrack. I could see it becoming a new motorsport. Welcome everybody to the Warped 100.
I've been totally thinking about that for a long time now... And it's so crazy that you said that because I literally in the last 4 months pulled together all the components to make that happen in a video... We think the same! That's nice
@@WarpedYT I want to see that video when you get it done that would be awesome! 👍
@@WarpedYT Count me in as your sponsor.
Now the question is which vehicle is going to be built around it
LOL only if you could pull a trailer of Nitro otherwise 2 minutes doesn't cut it. Nice idea but it wouldn't work. 🚗
Finally! something to do during winter.
I'm thinking at 28cc it might be able to power a super lightweight go-kart... obviously only to about 2 mph but it theoretically might be able to do it with enough gearing advantage...
In slow motion it definitely sounds like a v8 lol
The thing honestly sounds almost like a baby nascar engine. Love this little monster
sounds nothing like a nascar at all lol
@@THESLlCK it does with the full muffler. After cutting and removing it's just like a chainsaw
Your channel is sofa king cool!
This is not a toy, but a serious machine.
Agreed!!!!
Q: What did the short fat cactus say to the tall skinny cactus?
A: You can't be Cereus!
Then why did I cackle uncontrollably with joy when I clicked the link and it fired up?
@Mika Yes. My wife is into that kind of stuff. No need to be all together, as well.
I don't know, what serious application would this be used in?
This has giving nitro a second chance and I love it... I have their single cylinder nitro engines an I love them
I’m not keen on nitro engines, they’re too messy to run.
China needs to design a wet sump, oil pumped gas V8 the same size to be a winner in my eyes.
Yeah "China" get on it! Do hard work in exchange for money we print. America demands serious toy V8s.
A set of zoomie headers would be 😎 cool!
Crazy how much juice that thing consumes.
Who came across from donut media ? 😂
Amazing peace of engering 👌
Collector's merged into an x-pipe to duals would sound the best imo, you'll pick up some scavenging and drastically improve the sound. Either that or headers merged into a single large pipe.
I think you are correct!
@@WarpedYT yep, I see a lot of comments about back pressure being needed, it's simple not true, you do need some length for the header to keep the valves living. The back pressure argument has been disproven many times I've read that in the comments quite a bit. As drag racer it's simple not true, any back pressure will hurt power if the exhaust is designed efficiently to scavenge.
Like to see it with a scatpac exhaust system
This is a man's definition of, aww so cute
It's misfiring badly... When you have so many cylinders, you need a proper ignition system. This engine needs real sparkplugs and an Electronic Ignition System to create organized firing inside the cylinders.. It's a shame they did in Nitro intead of pump gas. No oil pump either. Improvements need to be done here.
I doesn't even have like a proper oil sump, the crankshaft only gets lubricated be the nitro-oil mix that passes through the rings
@@eljaibas16 I wouldn't have approved such a crappy engine system to be taken to production... I mean, how is this supposed to compete against a brushless motor.. let's not even talk about price differences.. a premium brushless motor is about $200 bucks.. 8 times cheaper, and 20 times cleaner.
This engine needs:
*Proper Ignition System with coil box
*Real sparkplugs
*Crankshaft position sensor linked to ignition computer to tell the sparkplugs when to fire.
*Oil pump to bring oil to the head.
*Piston Ring sets to increase compression
and something extra but really nice:
*a hydraulic torque converter to be able to use combustion rc engines in rock crawlers... centrifugal clutches suck at low rpms.
@@P_double_H but they dont sound like anything special. who cares about your dewalt BLM rc car
@@lsxbigblock6524 what are you talking about man.. did you even read. What car are you talking about.. you need social skills for your soul.
@@P_double_H Agree, for that kind of money it should have a real ignition and lubrication system, expensive toy beside it takes a lot of fuel, awesome tough
@8:13 now that was the money shot I was waiting for
make for it an twin turbo setup
You should open up design and fabrication school and people will line up. Your videos are a joy for us simpleton that still use an angle grinder and a drill to fabrics parts.
This is really cool. However it blows my mind that there is enough demand for these to sustain a business, even though you can buy a REAL engine for much less. Still very cool.
Yes I am wondering to, 2 grand is a lot of money for that toy
This made my day thank you
Has Biden affected the price of Nitro ? lol
7:27 the moment when your weed wacker wont throttle up but you try anyways hoping the bad gas blows through 😅😂😂😂
I wonder how many times the people at donut looked through this video to make sure they got it all right
While this V8 engine is small it is by no means the smallest. If you visit the Craftsmanship Museum in Carlsbad, CA you can see V8s that are quite a bit smaller as well as V12 engines that are also smaller.
electro starter bought me completely... whatta piece of machine... can wait to finally be able to afford me a new V8! MadMaxII here i come
Now I want to see this in a bad ass rc truck.
Year's ago there was a guy building Supercharged OHV V-8 engines. His name was Gary Conley, of Conley Precision. He built a Dragster and a Shelby Cobra equipped with one of his engines. They put out 10hp! His shop caught on fire and I think he quit. I think there's some UA-cam videos out there. One guy built a Grave Digger Monster Truck, another, a V Drive Off Shore racing boat, that had 4 Supercharged Conley V-8's! Super cool stuff.
how much horse power does that produce?
bro is this the same engine donut couldn't get started lol
Real cool again. Thank you
Poor Nolan from Donut.. You did what they couldn't.
I felt sad that they couldn't get a running, but in reality these projects are damn tough, especially these little engines, they are not easy.
Nolan is a boss. Im sure he will get it soon.
@@WarpedYT I can tell! You made it look easy, magic of editing!
great, great clip that the vast majority of **us wouldn't be able to see without these clips... love this channel
