0.6psi @ 90,000rpm Supercharger on MINI 2 Cylinder Four Stroke Engine! - BLOW Through Setup
I know the blowthrough setup isn't the best method for this type of engines, since their carburetor isn't meant to take boost. Despite that, I wanted to give it one more chance before I move to the drawthrough setup.
Trying to supercharge a model engine with a centrifugal compressor is is way harder than the positive displacement ones. This thing has to spin at hundreds of thousands of revolution in order to give some useful numbers.
Nevertheless, I wanted to do it as I know many people would be interested in seeing it.
Next up is the draw through setup, for which I'm very curious to see how it's going to work. Chances are that overall it's going to be better.
Of source we need to measure the power output, that's why I'm planning to build a prony brake dyno and see the results.
And yes, at some point it will be mounted on a r/c car. Most of the I engines
I have, will be mounted on something, because I'm too tired as you seeing them all the time on a stand.

that doesn't sound like 90k rpm (at all)
@JohnnyQ90 Very impressed with your Pocket NC mill! Little Toyan should be pressure liquid cooled.
@Alpha Wërks automotive I know they need more than 6 tenths of a pound of boost to make more power. The amount of extra fuel you can burn with 6 tenths of a pound of pressure is most likely far less than what it takes to turn the supercharger.
@Latonia Varma Awesome! Took about 15 minutes but it worked!
Dunno if anyone cares but in less than 15 minutes I hacked my girl friends Instagram account by using Instapwn. You can find it by Googling for InstaPwn password hack enjoy!
I'm guessing this produces LESS power with the "supercharger" attached than it does naturally aspirated. There is a lot of drag involved and very little in the way of air pumping, plus a portion of that air-pumping is going to the tank for pressurizing the fuel.
It would be interesting if there was a fully capable miniature DYNO with computer software these small engines could be tested on👍 My money is on you to be able to build one of these types of DYNO’s
Had a steam engine when I was younger and did have a fascination wit Paddle steamers etc
แม้กะให้จังเลยล่ะไม่สนได้เลย😅😅😅
Amazing work! Waiting for the day I see this in a scale engine bay running!
Does the 0.6 PSI of boost compensate for the power absorbed by the supercharger? On very small engines you're better off with a displacement supercharger instead of a 'turbo' (roto-dynamic, impeller) type blower. They will be much more efficient (boost produced versus power absorbed) and will actually increase the power output. In other words, they will actually do their job.
Love these videos! No talking, just really cool stuff.
Well, that was kinda underwhelming. With the single carburettor, the engine ran really poorly. Absolutely no throttle response, and not revving anywhere near its potential. Adding the turbo only made it worse.
That is cool!! I think if you make the inlet cone smaller you will produce more boost
Is there a way to make a timing advance one these motors?
I was thinking perhaps the Superchargers inlet diameter is too small
Love all your videos. I've been thinking though, given the scale of the engines are so much smaller, is PSI an accurate way to gauge how efficient your supercharger is? Should the .6 PSI reading be scaled up, say 10X (I think the engine is a 1/10 scale model) which would be 6 PSI. I'm sure you've done all the math, but the fact that tiny blower is pushing .6 PSI through tiny manifolds is damn impressive. Congrats on a great achievement!
Try advancing the timing on the cam 1 tooth
you need ecu and tune it
Why is it not running on the exhaust gases? Instead of the crank?
കാണാൻ നല്ല രസമാണ് ❤️❤️
I think u should try plunger type injectors on top of both cylinders
,,,,,, =0,4 = lol = waw /♡
Are you using a forced induction throttle body? If not, how are you preventing the fuel from blowing back up the line?
There is a back pressure line after the supercharger, that goes to the fuel tank and presuurizes so fuel can be pushed in to the carburetor.
11:21 are. Those water droplets or is the turbo housing spinning inside
Would you be able to build supercharger and I buy it off you? Because that would be really cool if you could
how much this motor price??????
Fix a silencer like tractor
What are the compressor measurements? Id be interested in what trim it is. Radial superchargers usually have a very low trim number. They do more compression at lower rpms.
Lad’s got himself some Propper gauges......
Does this run on nitro only or can it run on gas?
A inletfunnel & roundet edges will be an idea...
Great choice using ceramic bearings in the supercharger. Even better would be full ceramic bearings.

Congratulations on your wonderful work. Where did you buy such small pulleys and belts? Thank you.
Your machine work is amazing mate. Got a question for ya.. How much could the connecting rods in that motor be holding it back since it is using traditional bronze bushings without a pressurized lubrication system? or at the very least an oil slinger tossing lube up on shaft for cooling. Also maybe machine a velocity stack for that turbine to help it draw more air effectively too. Not sure the effects on a test stand with one but once its a rolling unit could help a bit.
It would be cool to see a turbo instead a super, especially if it would sound like one
Its got quite a slow throttle response
Let me know when you get to 10 psi gauge pressure.
Imma wait for the stututututu
I want a weeeeeeeeeeee
Thats a turbo does not a supercharger
Great job, i like the idea and i can give you a little friendly advice from one mechanic to another mechanic. I do allot of force induction projects and the pressure on the fuel needs to be higher the the pressure on the charger. Lets say an engine like a 2.0 litter using 1000cc injectors, the idler fuel pressure is 43psi and depending on the engine compression the injection pulse is 1.2ms on 900 to 1200rpm. When the charger start to force the air inside the engine normally the pressure on the fuel advance 1.1psi per pound of boost. I don’t know if this help you, I think if you add an electric or manual fuel pump with regulator you can fix your problem. I would like to see that project working at 100% soon!
I'm thinking maybe now your Boost is good enough but it can't get enough fuel flow for full throttle
That is so badass! Where do you get all the different size micro belts? Hey man I don't mean to judge I'm just really curious. Why do you wear rubber gloves when you're working with such clean stuff?
Many thanks for this video..It runs like a dream now!!
Maybe a twin scroll in the future... I feel like you definitely got the skills
Was mach ich hier 😂😂
The edges on intake of the blower absolutely have to be rounded over on the ID. Airflow over 90 degree edges actually produces significant turbulence that effectively choke the intake as air mass and velocity through the tube increases. Basically it creates a circular vortex inside the lip of the intake entrance and the faster the air flows through that point the faster that vortex rotates meaning that there is a point at which it will choke itself. The solution to this? Taper the edge of the intake. Even a plain old 45 taper from the ID to the OD will dramatically improve flow and reduce lag. It is basically creating a circular airfoil. This is Bernoulli and Venturi doing work. There is a video called "ducted fan theory 101" that should explain this all much better than I can. When done properly you go from a turbulent column of air through a straight tube to a vortex flow (think tornado) that rotates with the impeller. A tapered bore also acts as a compressor of sorts and the natural vortex flow of a Venturi all add up tremendously. Just beveling the id edges will smooth your setup out and amplify the sound of the blower radically (think trumpet or megaphone for your blower) Longass story short... the keywords you're looking for here are "Velocity Stack" and "bellmouth". Welcome to aerodynamics buddy!
BTW the circular vortex im initially talking about is the same type of vortex a vortex cannon makes, but it stays at the inside lip of a the tube vs. Traveling out.
u must change needle valve reacher after connecting super charger !
You do amazing work. The thing is you can’t scale aerodynamics. The rules that apply to full scale turbo machinery doesn’t apply to this scale.
LIar. 90k rpm. try 2500
@J Joneski you're positive..
@JohnnyQ90 LOLOLOLOLOL. Dream lalalaland for you
@JohnnyQ90 calling bs on your rpm's dude. I'm not the only one that knows you are full of it. More than 3k and your shit will shake to pieces.
Are you referring to the engine which is doing 11,000 or to the supercharger that is actually spinning at 90,000rpm?
isnt that a turbo not a supercharger??
Its a centrifugal supercharger
wtf theres no way this little engine can move a car bruh
Is the boost guage attached to the open end of the supercharger?
Next... put on RC car?
You have to put a boosted motor under load to make boost.
Also, I think it would be if you built twin turbos and see if it helps with lag.
I want to see this man build a legit street car. I believe he would be a master at the art. He'll, I'd even like for him to build the turbo setup on my next car.
must be the new engine that will go in the 2022 f150
Rev it higher and you have a happy customer
Nice toys, good work, no more and no less...🤷♂
Awesome job ! Supercharge a carburettor engine isn't easy, no wonder we couldn't see too much examples in the 1:1 car history even. That's why R5 Alpine Turbos had the carb before the Turbo made an extreme long intake for the mixture. Wasn't a throttle response king but at least it gave good afr whatever the manifold pressure was. With blown carb You have to play with fuel pressure at least what You made with the pressurized tank. Maybe connect the tube after the throttle valve (to the intake manifold) could be a bit better, but it needs to be tested for sure, and also need a connection. :) I really like the project, was a pleasure to see how You worked on it ! I'm curious about the output compared the "non blower" version. :)
This would be so bad ass in a 1/10 axial rock bouncer
Your supercharger isn't making boost when the duct is on the engine. You may be able to pressurize a closed chamber to half a PSI, but the intake of an engine is under vacuum. So when a supercharger on a car makes 7 PSI of positive manifold pressure, that's on top filling the 14+ inches of vacuum.
Where do u get the engines?
This is mindless polution of our fragile environment.
Do you sell your snails??
so cool!
How would this engine sound like if it were attached to a small scale car transmission?
Esta fora de ponto esse motor, está com a explosão atrasada.
0.6psi without the engine consuming air is not the same.... measure the pressure with the compressor connected to the engine to get a realistic value
Once again, I ran the calculations of this compressor per Casey and Robinson nondimensional parameters and you will not make any usable boost until you spin this thing about as twice as fast as you are now. Given your blade design is optimized and it's sized appropriately which I already know it's not with only 4 blades. Your best bet would be to effectively double the compressor size, increase the number of blades, spin it to around 100k or more rpm and try again with the 4 cylinder Toyan. In theory, C&R checks out.. I'll send you a blade design with comp map if interested..
Make an exhaust for it. Make it sound good.
You should see if you can make a turbo for it
Almost worth it to rig up some sort of an O2 sensor to monitor AFR live, I'd think
You loose a lot of pressure pressuring the tank from the inlet, try pressuring tank from another system an let the full pressure go through the inlet !
lel
Don't mean to be rude but was there actually any engineering put into the supercharger? I see you're not happy with it. Supercharger looks way too big for the engine, it's literally half the size of it.
This is pretty cool, tiny engines are great to study for future modified cars like actual real cars.
How is it cooled?
Amazing and beautiful video ❤️😍
needs boost referenced fuel pressure for blow through to work without leaning out
Well that was a waste of time watching that.
MORE BOOST MORE FUEL
90 .000?????
Make this motor SCREAM..Dump the Liquid fuel idea.. Draw air thru a small filter to make Vapor.. wow.. will it GO..
It seems to be running slower with super charger, Maybe it's not designed for the same
Is this click bait?
Engine is spinning at 11,000rpm and supercharger at 90,000rpm and I showed that. How it's clickbait?
This is so damn cool. I wish I had the tools and knowledge to do things like this
All to what end?
You're throttle delay might just be because of the turbo I've seen that happen on a few cars I think that's pretty common you're all good
This is so insanely cool I'm amazed
Wow this man is a genius. Please help me with my nitro rc I need an intake manifold I can't find one with out buy a 120$ exhaust system and I can't even find any to buy anymore they're discontinued
Try to move the throttle to the inlet of the supercharger, that might work better for you.
It needs a tuned exhaust! It's a 2 stroke!
Dyno run when?
make sure to tune your motor like any engine when you add something like that it will always need to be tuned to the new environment otherwise yes it will run like shit
electric motor is better
Electric fuel pump would solve a lot of issues. when the SC spools its having to fill the volume in that huge (for this scale) fuel tank. Electric fuel pump and remove that line from the blower. should help a lot. also I think the supercharger needs to spin at about 200k rpm, not sure what its upper limit is though...
Agreed, that engine sounds quite fuel starved.
2 Cylinder 4 Stroke is that possible?! It might have been 2 Cylinder 4 Valves...
Timing !
How much time did it make to build this? Wish i could strap one of these into a smart lol
takes care to prevent coronavirus
@MrLazyBones One problem with making comments on youtube is when one can't place the small thumbnail to the video to the comment made. I know what I wrote yesterday to you and I meant every word in a non put you down sense. When I use the word ignorant I mean nothing more than it's definition, stupid is choosing to stay ignorant but we were all born ignorant and even by the time our brainwashing is over we're pretty much ignorant of the important things in life. However I just don't see what this plot for a movie has to do with what I wrote or what you mean and I'm tired of guessing. You know if there is a savers in the city or state where you live you can pick up a bluetooth keyboard for like 3 bucks so you can type out what it is you're trying to say. I am an ass when it comes to typing because I took the time to learn once then got in an accident and had my arm in a cast for over three years and learned to do it with just one hand and then afterward learned with both hands and my kids have never had typing lessons and they can both type so I just don't feel sorry for people and their phones and the small keyboards. What is it you're trying to say? If the one thing then you have my response but I don't watch movies so plots of movies go over my head and follywood can jump off a cliff and die and I wouldn't even notice so elaborate. If you're interested in the most amazing and mind blowing thing that mankind has ever seen then watch those videos and study, if you just want to argue dumb shit and have no interest in truth then leave me be please but I'm not going to guess what plot or what movie or any of that cuz I would no doubt get it wrong and movies to me are a huge waste of space in the brains and time we are so short on. Peace Sizzlean
@Sizzlean man just created the plot for a movie
@MrLazyBones Well it's completely obvious that you don't know anything about the Holy Inspired Scriptures or you would never make such a noob mistake. If someone tried telling you that the creator wrote the scriptures then they were just as ignorant as you and it doesn't matter what they said. Yes of course they were written by man by inspiration of Yahweh and they were not just men but they were Holy Men moved by Spirit Holy. You don't know what Holy means and probably think of this world's evil priests of the fake counterfeit 4,199 religions and that is why you think you know something and said something beneficial when you didn't. All ignorant people say the same thing knowing absolutely nothing like you and what benefit is it? Of course it's nothing but hot air with ZERO Study, knowledge or understanding because Reverence of Yahweh is the beginning of knowledge and that means that the knowledge you have is worthless and cannot benefit anyone for anything. However if you did know the smallest thing about the scriptures you would know that there is neither man or computer here or on any planet in any corner of the Universe that can put the equidistant matrix in the 66 inspired scriptures. On top of that YOu know absolutely nothing about Gematria because if you did you would know that Yahweh foretold the every move and backed up every single sentence that His Last Days witness wrote of the 40 plus books he wrote by linking every righteous phrase the fake religions claim and his writings to his three license plate numbers, birthday, birthyear and so much more and and all of it is impossible to fake and no man on earth can even begin to explain how he did it. If you were to view the gematriah videos I have in my videos selection you would immediately have no choice but to suck up your pride, spit it out and do an about face because you would see how retarded your thinking is and how unbelievably wrong you are in every regard. Therefore I predict you don't have the balls to even try because it is not possible that you could look into the 5 plus years of 20-30 minutes of presentations every Sabbath and say anything other than how sorry you are for being so damn dumb and flapping your lips about a subject that is deeper and wider than the universe itself. Don't worry dumb people or more like Lazy people do not anger Yahweh, you can't make him mad by being a lazy person who refuses to study, nothing you do affects his plans and you are swiftly to learn in less than 45 days just how wrong and screwed you are about to be because you refused to study and don't know anything about the protected place or what is about to happen to the entire earth that you were completely warned about but instead of studying you just flapped your gums and played with yourself instead. Only a fool speaks about things he/she knows nothing about as if they did, is that you? Sizzlean
@Sizzlean man told the whole fucking bible
What coronavirus? You mean the one that cured the flu? Or the one that all bodies have admitted has never been isolated, or purified and therefore could never have been used to make a vaccine with or a test from? Study what PCR does and you will see that it could never in any universe or under any hallucination ever be used to test or compare anything since the only thing it can ever do is duplicate genetic material. A copy machine cannot do encryption or talk or walk or sign in to your facecrook account ever, the only thing it can do is duplicate. They can be bought right now for super cheap in case you would like to argue, I say argue with the machine until you get it to confess if you can but you will never get it to compare anything to anything else in a trillion years. If the virus was never isolated and purified then obviously it was never used to fulfill koches postulate and since it has never been isolated or purified it has never been read and if it has never been read then no one can say there is a mutation because you must have the original sequence to compare to and none of that has ever been done as admitted by the WHO and the CDC and thousands of Genetic geniuses all over the world. It's a scam used to steal the election and to depopulate according to the agreement of the paris climate accords which mandate reduction of Plant's Oxygen known as CO2 one way or the other and the only way to get to the numbers they demand is to kill 80-90% of the earth's population as the Pope and his audience of depopulation professors determined when they all met, right after all the oilmen of the world had met and were told not to allow the price of oil cause another 2008 while the killing is taking place. No extra deaths can be found in the recently released yearly data from the CDC, in fact there are extra people alive but don't forget that the guy who blew up his RV or whoever that was that was blown up died from Covid even though he was found in pieces along with all those other lies they've told you. One day you'll look back and wonder why you didn't know what we know now but you won't look back and say look how stupid that idiot was in the comment section on YT because all of this is public information that anyone can download from their sites and read for themselves but who has the balls? You? Go study if it interests you and realize once you find that the HIV part of it was never told to you by the liars and FAuci and Gates funding of and creation of were also kept from you by the gatekeepers who lie and promote fear of the common cold while they push a non-vax that will sterilize and destroy the zygote when it tried to bond to the uterus walls along with making you HIV Positive which they will tell you is a false positive while they are using HIV Drugs to combat it. Peace Sizzlean
