0.6psi @ 90,000rpm Supercharger on MINI 2 Cylinder Four Stroke Engine! - BLOW Through Setup

16. jan.. 2021
832 226 Ganger

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.

    • @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.

    • 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.

  • 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.

  • 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.

  • 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!

    • 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.

  • 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.

  • 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!

  • 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.

  • 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. :)

    lee Boylee Boy2 måneder siden
  • 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.

  • 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

    Diego MayánDiego Mayán2 måneder siden
  • 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..

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.

    • @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.

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?
