Twin Supercharged 4 Cylinder Nitro RC Engine
ฝัง
- เผยแพร่เมื่อ 5 มี.ค. 2021
- I build a twin compound supercharger system for the mini 4 cylinder nitro RC engine.
I've seen people on TH-cam recently trying to make boost with these mini superchargers, with very little boost being made, all I can do when I watch these videos is shake my head, so I decided to show them how it's done!..
I made about 3 PSI of boost here which some may think is substantial but I think is pretty elementary, I'm looking for some serious boost pressure in the future.
in this episode I build the entire compound supercharger setup, and at the end of the video I tear the entire engine down.
originally I was going to include the full tear down video but I decided not to because I found it boring but if you decide that's something you want to see, just let me know but in the next video with this engine where I use the toyan L400 engine For an upcoming project I'm probably going to build the entire engine from scratch and make some modifications along the way.
tell me what you think about this video and below please find the links to the engine I use in this video as well as the app Text To Shop.
thanks for watching and if there's any additional information you want to see in the description here let me know and I will include it in the future.

Alot of people asking about the WaterJet I use, heres a link: bit.ly/ProtomaxWaterjet
Bro - 8:11 I knew I would see this ..to be honest - I hated these engines straight out of the first notice- for many reasons ..one they were originally made for a minibike and a fail attempt at that.. Too wide- making the balance dangerous for a little kid along with top heavy- the aluminum is very poor quality the plastic gears still a bad idea .. But if you use only 1 supercharger you would have gotten at least 6 psi to 8 maybe ..the 2nd one added drag.. Not actually increasing the "compounded pressure" I love your channel and you are by far a better engineer than the makers of that engine - ways to fit the problems at hand (the metal in that engine will loosen its form because it's like cheap Chinese steel ..it has an extra mix of bad fillers causing the metal to bend break distort and the weight will warp and shimmy ..ok the overheating problem - you and I both think outside of the box ..maybe I even do it more but you managed to put alot of great ideas in to works *-applause-** so arctic cpu thermal paste could be smeared all over it .. Forcing the temperature 🌡 down ..i use it on heatsink it drops my cpus from 198 degrees to 135 - running a robotic automated program constantly processing for days on end - use it itll work there to .. You need a fan blowing on that engine itself ..anything with the force or a cool hairdryer is enough to get your heat down.. The balance in those pulleys and parts are whats the major problem - if you remake that engine using your own 3d printer and metal you'll come out much better I'm positive.. Be safe Bro! ❤- *Wonka*
there called twin turbos
@@lifeofjamesmcwilliams6995 twin turbo is what's on the yellowbird 911 Porsche ..theres a major difference between the way they are connected to manifold.. They need to be connected but thier own singular intake not by being on same line.. Else explain the 3psi for what should have been 20psi..
How about a liquid nitrogen cooled engine? Haha
i would like to see that engine at a bike or boat or sth =D
Insane! 3 psi on that scale is monumental! I agree, going bigger should bring even better results. Also, double check all connections for boost leaks. I thought I sorted that problem out, but it was still there. Can't wait for the next part!
I figured you would be all over this hehe
Battle who will get the most power out of that little toyan
I like your videos very much for all the ingenuity and craftsmanship, but you got to admit that warped perception also has some fine tools and knowledge
Why are u not verified?!??!
You did it better and more professional. Your was hard to get to work but this is Fake
@@motorenbastler9289 I don't understand why nobody is suspicious? First off, two of this "compressors" the same size make no sense at all, in a compound setup you need different sized Turbines. When he said the boost of the two turbines add up, I completely lost it xD. Even a tiny bit of knowledge in physics and you would realise that can't be right. And then this 2 little plastic fans making 3 PSI of boost at that low rpm? They do not even compress the air because they can't with this huge gap between the Compressor wheel and housing.
Dude It's not real.. Look closely...
Amazing job with the superchargers! Looking forward to seeing more!!
Absolutely. 3 PSI is incredible at that size. Can't wait.
Thank you !!
That's what I say ever Saturday in anticipation of the next Project Farm! :-P (yes, I am a professional brown-noser)
Are you gonna test that?
Are they not called prochargers
When you run two stages of boost like that, you need to size your compressors accordingly. They can't be identical. When they are, either the first stage is overflowing or the second is starving. The first will necessarily need to be bigger than the second.
I've run some numbers for you:
- The engine displacement is 14cc
- Maximum rated speed is 13 500 rpm
- Total volumetric flowrate (ideal) at that speed is 1575 cc/s (call it 1600 or 100 ci/s or 3.34 CFM). You can't fill the cylinders that quick, but that's the goal anyway.
- Your compressors have a pressure ratio of about 1.68 (10psi overpressure)
- Assuming adiabatic compression (no heat loss), that means a volume ratio (inlet to outlet) of 0.69, or sucking in 1.45 times more air volume than what comes out. You'll obviously lose some heat, but this should be close enough
- This means that the second stage must suck in roughly 2300 cc/s, which means the first stage must be able to supply that at its outlet
- Assuming the same pressure ratio, that means the first stage must be sized to flow about 3400 cc/s at its inlet
You also need to mind the heat here. Keeping to the assumption of adiabatic compression (because the air moves fast enough to lose very little heat), and assuming your workshop is at about 20°C (68°F), your first stage outlet temperature will be about 67°C (152°F) and your second stage - 121°C (250°F).
Obviously some heat will be lost to piping/environment/etc, but at those pressure ratios your cylinder inlet temperature will still be upwards of 100°C which may or may not be too much for the engine. I'd check with Toyan. You might need intercoolers to protect it (either at every stage, or just before the manifold). If you do, it's worth recalculating the sizing for the compressors, because the total volume ratios will change.
@jesse james I don't, but perhaps I ought to - looks like good fun! I'm an aero engineer, we used to do these sorts of calcs for jet engines just for fun at undergrad ;)
In fact I'd enjoy helping out with his jet engines more if he's interested, but this stuff needed much less information from him to put together.
These days I mostly do advanced modelling for work, so going back to basics on side projects like that is quite enjoyable.
As for electric motors, I know they spin when you apply current :P Don't they use them to start jet engines?
Joking aside, you can get some pretty cool control systems for those, and if it's a standalone commercially sold unit you should be able to get a data sheet for it which has performance curves, power limits, thermal output, etc. And if you have a mystery motor (or its data sheet is barren), they're not too difficult to characterise, so you know exactly what you're dealing with.
Can you make a copy of your brain and send it to the cloud? I’d really love a download 😂
@@LumiusStrife 🤣
Now *THAT* is how you science the shit out of it..
what a god comment
I am seriously impressed, the welds, the programs it takes to do this, the expertise, the measuring. Definitely earned my subscription!!
You know my guy likes to party when he got missing fingers
I didn’t even notice til you said something 😅
@Kory Thigpen of course, 8:34 right there he could've lost a couple more...
@Kory Thigpen no his dog bit them off
He doesn't have any missing fingers we just have too many....
Maybe it happened while he was making his engine. 3D printer can be dangerous. But I don’t think it was that.
The "compound" idea is flawed; the pressure isn't additive the way you're calculating it. That's why you're getting so little pressure overall. It wasn't the boost pressure pushing out the intake pipe - it was the vibration. You have a bad bearing in your idler pulley. And you're running your fuel mixture way too lean, which is why your engine temps are rising so fast; your "increasing the air charge" isn't all that you need to do!
Your comment is way too much underrated...
Facts
unbelievable. wouldn't let him work on my motors if it was for free.
He said he was running the fuel pressure regulator with reference to boost, so it should be increasing the fuel pressure with the boost.
@@shredder8910 some say fuel pressure has nothing to do with the air/fuel ratio. if its increased the Fuel pressure RATIO, then yeah it will run rich, but just the pressure it will run lean, which is clearly the issue here
It's fantastic how you are able to go out and get one of these little engines and be able to show your children how an engine works in real life without having to take your car to bits .
I'd also love to do a build with one to make a R.C controlled car or boat . What a great build this would be and I would love to see what the potential you could get from this
AFR's are massively important to keeping the engine cool while running aswell. Fuel "cools" the combustion cycle. so a richer mixture may not produce quite as much power, but it will massively improve the temps you're seeing and how fast it gets up to temp.
Super cool video though, these little motors are super cool.
I know it's it's old video, but I came to say this as well. He's adding air but he didn't talk about increasing fuel. And the Temps and overheating seems like it was running very lean. Which is great for power but not for the engine
@@tilldeathdoesmepart Extra fuel is being added via the preasure reference to the fuel tank. As boost preasure increases the preasure in the fuel tank increases. Which in turn adds more fuel delivered to the carburetor at an amount directly related to the amount of boost. So it shouldn't be running lean at all.
The engineering alone... Wow
Thank you
@@WarpedPerception WP. I’m sure you noticed this already but just in case you didn’t, your beautiful little exhaust gasket seems to be leaking. Love your use of the plasma cutter. Makes we want to save up for one! Keep ‘em comin’, man ;-D
I’d love to see this in an absolutely insane RC dragster
Maybe a rc drifter or burnout car
Electric rc dragsters would walk it every single time.
@@GritsnBeans no shit

@@GritsnBeans so… it would go out loud and in style
This is so freaking wicked!!!! Thanks for making something so cool, and showing all the programming it took to build all of the brackets and other parts!!!
You sir are super talented & honestly a genius of course it has to be nice to have a waterjet & lathe at your fingertips. All you need is a vmc. Nonetheless to have all your skills, programming, welding, knowledge of electronics, machining, engines, etc. I'm in awe. Being a machinist all my life your skills are 2nd to none. I stumbled onto your channel by accident with the jet go cart. I'm so glad I did. You have a new subscriber. I'm intrigued by your genius. Keep up the great work. I'm enjoying your vids. Thank you.
One thing.
For compounding to work the first supercharger needs to be bigger at the same RPM or be the same size while spinning faster.
Because right now the second supercharger is creating suction at its intake which completely destroys the boost from the first supercharger while creating more heat than a single charger setup.
If I am not wrong he could also run a different sized pulley on the first stage for more rpm
the point of this video is to destroy the engine.
Incorrect. Superchargers produce positive atmosphere, it can be rated in cfm, cubic inches, liters, several ways. For every rpm the supercharger turns it creates positive atmosphere displacement. Compound simply means 2 or more parts doing positive displacement. It's the same concept of when people used to stack 2 roots style blowers on top of each other, they would have the same positive atmosphere displacement even if they were side by side. Superchargers are much simpler than turbos in that aspect. The only problem I see in this setup is if the first supercharger inlet I.D. is enough to flow the amount of air required by both superchargers
Daemon No it’s to make as much power and boost as possible, and not give a shit if it blows up the engine.
@@pw383426 let's go through this. Superchargers don't produce positive pressure. They move around air so that it can't go back. If you connect one to a long open pipe ( or a mine which is what the things were first designed for) you'll find that it isn't prodicing any pressure. if you connect it to a pipe that is being sucked empty at the same rate as it's filled (for example by another supercharger of the same size turning at the same rate) it also won't produce any boost.
Now lets use some number picked right out of the air.
The first charger takes 10 liters and turns it into 5. the second one also takes 10 liters and turns it into 5.
They are spinning at the same rate so they are sucking in air at the same rate. But the second one doesn't have access to an unlimited supply of air. It only has access to the 5 liters per second that the first one provides.
So it pulls a vacuum destroying the boost produced by the first supercharger.
so in conclusion the first supercharger needs a smaller pulley to actually be useful.
which also happens to be what can be seen on every compound charged racecar that has ever existed.
Looks like you're having fuel delivery issues as well. Using boost pressure to control the fuel pressure will never allow you to have full throttle. At part throttle you're building boost against the throttle blades, but on the engine side of the throttle blades you have less than the 3psi the superchargers are producing which is allowing the 3psi of fuel to be injected. At full throttle the boost and fuel pressure will be equal and you'll never get fuel to the engine. In simple terms the fuel pressure has to be higher than the boost pressure if it's ever going to work at full throttle. You have to remember those aren't carburetors, they are a very simple form of mechanical fuel injection and the fuel pressure has to be higher than the boost pressure.
Yep exactly he’s running lean causing the heat.
I have no idea why people insist on blow through systems.
Unless he runs an electric fuel pump with a boost referenced pressure regulator to get that additional differential pressure, it will remain lean.
😉 ❤️. You're absolutely correct, but my goal for this video was to set up the entire supercharger system to show people that you can make boost with these little engines. You are dead on accurate everything you said, I have my list of open items that need to be corrected to make it 100% And before I use this engine for my project I think I'm going to do an even crazier modification..lol. I appreciate the feedback I love talking to people who know what they're talking about.
@@RonaldMcDonald6969 it's mainly running lean because the fuel pressure versus intake pressure versus how much extra fuel you need to meet the increased oxygen from the boost is a ratio that is not linear if that makes any sense. There are other ways to make this work, and I was only running half throttle here, can you imagine full throttle?
I'm glad someone finally made an app like that. I thought of that idea years ago but wasn't sure how the heck to get it done so props to you and your sister for knocking that out.
You're having a fueling issue. Even the most efficient naturally aspirated engines run at several pounds under atmospheric pressure because of vacuum dilation from drawing in the air using a vacuum pulse. Since the engine is now running at 3 pounds over. It's actually seeing double the air. NA at high RPM is 14.5 - 8 = 6.5psi or less. This is why all but the most vacuum efficient motors see power loss at high RPM and why mid-history F1 engines could save fuel and still turn faster using high RPM NA grip. Then they survived the early turbo competition by running higher compression and using velocity stacks (like yours does). Giving them 7-8 psi (1.5 psi advantage). Remember this was before variable velocity stacks were invented and computer maping of intake plumes to time the refraction of intake pulse echo.
Now your setup is 3 psi over atmosphere 14.5 + 3 = 17.5. That's more than double the air even with your velocity stacks power scavenging the vacuum pressure pulse in NA format.
Now this is where the it gets complicated. Not only is there twice the air. Requiring double fuel to reach stoichiometry. People learned in the mid-history and before of racing to run richer mixtures well above stoichiometry for three reasons.
1.) Fuel cooling effect. The vaporization of the fuel draws heat away and puts it from the engine to the exhaust. Making better exhause flow, evacuation of spent gasses and cooling the head or intake gas. This also made more power by making the air charge denser alowing for even more fuel and therefore cooling.
2.) Rich mixtures turn more oxegen to CO2 and CO2 carries heat away with it. That why completely NO2 dependant drag motors use CO2 boosters to keep from melting pistons and valves. Enjoying a 2% power boost per charge and the ability to run even more NO2 and feul before structual failure of metal or meltdown/gauling occurs.
3.) A rich mix burns at a higher rate and continues to burn past the point of the exhaust phase. This creates more power and scavenging oportunities in maping the exhaust pulse reflection which then more completely emptyies the hot spent gasses. Which adds power by allowing more air and fuel to be added, but that also cools the engine better and the hot gas doesn't stay in place multiplying the cooling effect. Normally the forced air (boost) corrects this, but since you're running a naturally aspirated camshaft that effect is nullified.
Using a stand alone fuel delivery method (a variable electric fuel pump) and increasing fuel delivery (injector pulse duration in larger engines) should correct this (firstly) and gain you the most benefit.
Then change the cam.
Then run an inline connected exhaust header.
This will net 75% more power and keep you from overheating for 3x longer. Also allow close to an NA RPM ceiling.
I really appreciate your CAD skills, but this is what you missed. Engineering doesn't teach this stuff. It's all learned through asking race heads who've been learning these tricks for decades.
Can't wait to see you correct this and throw a rod for science. Get it on high speed please.
I was just about to say that. I might add that the dilation compression of the ventral cam is way too low under current atmospheric conditions. In order to fix that, he would need to triple the boost while adding fuel recovery in the midway valve tank rods. This will increase the power by reducing the power delivery in the centrifugal compression chambers. It’s just a thought but certainly worth a try.
Damn
Half right? Only as much right as warped’s right middle digit. It looks like a butthole in close up. Lil puckered innie. Makes you negative right, not half right. We are all now stupider having read this

Incredible and insane at the same time. Something about the scale makes this even more impressive.
@Mxrider2627 7
watching people make custom performance parts for these little Toyans could be the most entertaining and fascinating videos iv ever come across down the rabbithole
Excellent craftsmanship right there.
I think you need to 1) shorten your coolant hoses and 2) increase the hose diameter. You have a lot of resistance to flow through those long little hoses. You can see when the bubbles go through them how fast the water is trying to flow. Fast water = lots of friction loss
And faster the water flow thru the radiator means less time for the water to cool down, plus it doesn't have a engine fan. Also, I highly doubt this engine has a thermostat... a setup for disaster.
A larger radiator wouldnt hurt, either. A cheap 120mm aluminium PC watercooling radiator is like $10-$15 on ebay, tops. A 240mm radiator would be around $20ish.
A chunkier fan to draw air through it would also be needed. 3000-4000rpm Delta or Nidec fans would do the job quite nicely and aren't too expensive.
@@speeddemon1092 that sounds like the setup it needs right there.
@@garyr7027 that's why in a car , there's a right way and a wrong way to remove a sticking thermostat to get you home.
Don't just throw the whole thing out , you need to gut it like a fish and reinstall it.
Cut the pellet and spring part off , and place the disc back in , it's the restriction you need to maintain the right flow and pressure throughout the system.
It doesn't necessarily need a thermostat, it needs to have the correct flow and pressure on the system.
@@MrTheHillfolk fluctuations in engine conditions require fluctuations in the cooling system, only a operational thermostat can provide a constant cooling temps overcoming those fluctuations. Thermostat is nothing more than a valve controlling the flow to maintain a certain temperature. Sure you could run it without one, but without the proper cooling system setup, it'll either run too hot or too cool. In this case cool might be better since he damn near blew that engine up. In a real engine though, you really should have a thermostat, engines are designed to maintain proper temperatures for optimum fuel efficiency.
the amount of work and detail you put into this is unreal, LOVE IT!
That opening build sequence was hypnotizing
I just can’t get over how interesting and informative this channel is. He’s a beast of an engineer and machinist extraordinaire, welding guru mad scientist lunatic! Love this man!!!!
Man I follow you for years, it blows my mind the level of improvement in your "metal work" skill. Really impressive stuff!

*Nice work!* 😎 I think a small turbo engine war has begun 😂
Оо, Альфа и ты тоже смотришь))) Hello Alfa)
Из-за ошибки в проектировании, вторая турбина не повышает мощность! При последовательном нагнетании давления, скорость вращения первой турбины или её размер должен превосходить скорость вращения или размер первой турбины, т.к в условиях большего давления вторая турбина имеет значительно более высокий расход нежели первая.

Why are you celebrating the bare minimum of human character
What a beautiful engine. What he does here is just brilliant! Compound blowers on an L 400 ! WoW!!
When I hear " compound engines" I always think of WW 2 aircraft powerplants and the big Pratt n Whitney and Wright compound Turbosupercharged radials .9, 18, & eventually 28 cylinder.
That fuel system is super smart! Using the boost pressure directly to increase fuel! I'm sure it doesn't work perfectly, but the simplicity of it is what I love.
The engineering here is so awesome. Love this stuff man, been a big fan of this channel for a long time.
That startup at 9:48 sounds cute and mean at the same time
Lmao
Bro that's some mind-blowing craftsmanship on that intake manifold!
It looks great, fantastic job on this build it makes for a great video. Thanks for sharing.
Wow, extremely glad I ran into this gem of a video.
Excited to tune to future videos! Great engineering!!
Love the channel. One thing though. In a compound setup, your low pressure compressor should be roughly twice the size of your high pressure compressor. Have both compressors the same size doesn't yield any pressure gain and generally increases your charge temp witch costs you power.
You could probably also change the speed that they're spinning at as well, couldn't you? To get the gains that compound setups should get you
Yeah lol not really sure what he was going with here
Thats what I was thinking. I think he would do much better having separate inflows and combing them which might be an easier fix.
right on the money
This is absolutely incredible. Love the workmanship.
Thank you

Yeah that made a huge difference
I assumed this was a JQ90 video when I saw the thumbnail. Would be interesting to see lots of guys pushing small engines like this.
These things are blowing up on TH-cam right now.
I know I was fortunate to have the first prototype.. not that that's anything special or anything 🌝. I do think I am the first one to make boost with a miniature supercharger. It has been painful for me to watch other channels trying to make boost with these tiny little chargers when most of them are using the wrong compressor style.
Is that a pun?
@@billbergen9169 it is now lol

After seeing a couple TH-camrs fail with their forced induction and me recommending they try out a compound setup, I'm happy you decided to do it! :D
Also, I don't know if you would consider this or not, but I remember watching EngineeringExplained's video on a turbocharger which had a mix of axial and radial compressors on the inlet. So at the very entrance there was like a superchargers screw that helped keep the turbo from surging (giving it a compound effect and therefore raising the possible boost) and after that screw was the normal radial turbo wheel. They reported improvements of about ~20% increase in pressure, if you would be up for the task of trying to build something similar, that would be awesome! :D
This was the first I've seen from you and it was amazing!
This is my new favorite channel. Love this stuff
This is pretty awesome. My father was a machinist. A very well known, and in demand machinist in the greater Boston area, from 1960- 1996. He didn't have all the high tech stuff you guys have nowadays, but I guarantee he would love this video. He was the kind of guy that truly appreciated anyone that could visualize something, then build it from scratch. Very cool stuff man, and just know, that a very accomplished machinist would definetly approve
When you installed turbo , you need to install Samco sport hoses and you also need K&N racing filter plus bigger coolant radiator and oil cooler 😅
Wow. That's impressive engineering
Pretty darn impressed!!! Great video!
That's a dope lil engine. Would love to see how it'd do as a full size engine dropped in a miata or foxbody.
WOW- You got the tools, software and know how that really helps. The second I saw the initial start-up, I didn't like the way that belt was jumping. Too bad you couldn't add another belt tensioner. I was very impressed with the look and sound of that engine. The last engine build I did, I used a small block 400 to go into a 72 Camaro. If you aren't aware, a chevy small block 400 is known for running hot due to the fact that the cooling holes that normally are in small blocks become steam holes in a 400. I had to come up with a good cooling setup for this engine and did. Very interesting project!👍👍
I'm about to motor swap an m112 AMG motor into my old c class and see what happens 😆
Compound turbochargers are used on petrol too, common usage is a small turbo feeding into a large turbo. Small turbo spins up way faster but only provides a little boost, big turbo spins up slower but gives massive boost. Helps to even out the power curve compared to having just the large turbo on its own in a performance application.
Thank you for multiple subtitles!
Adding bolt on flanges to your intake pipes will stop them vibrating out. Nice work mate. 🦘🦘
When using a turbocharger or supercharger with nitro fuel you will need to richen up the fuel to air mix. It will keep it cool.
Yea; I was thinking the same thing
Damn bro….I can’t believe you made everything from scratch, well done!
Your welding skills are out of control!! Wow, very impressive
Tim, love your work! Really impressive. Have you tested the center main kit for the L400? Let me know if you are selling the kits. I have another new crank coming and would much prefer going back with a center main.
I would love to see a 2JZGTE scaled down - actually, I’d love to see a Mk4 Supra built the size of a Lawnmower, 🤩
That would be nuts
@@WarpedPerception I think you should be the one to pull it off. 😉
@@WarpedPerception A scale model mkiv go-kart with real scale model 2j wold be the coolest thing I have ever seen.
Even though the newer Supras get all the popularity I love my 88 mkiii turbo, I have had it for 15 years and I love the styling on the 80's Japanese cars even still. My first Supra was an 82 mkii and I got crazy looks anywhere I took it, nobody knew what it was LOL.
2 more cylinders and you're there baby
@@755hp that Barbie Jeep that grind hard plumbing is pretty wicked , it had like 50+hp and then they supercharged it.
Your shop is goals
i like how when it's actively breaking he just revs it harder
