Yes finally the return of the charger And happy new year to everyone reading this

Before judging or having suggestions for this guy. Let’s just appreciate he’s work and time he put into it. He creative af gj dude!

The amount of effort and knowledge it took to design and build this must have been insane.

Amazing work from one of my favorite youtubers! I just wish there was a way to measure the power output on such a small engine. I wonder how much extra power it makes! Anyway, keep the content coming! Happy new year to ya.

Jonny Don't be scared, increase that rpm to the f****ng stratosphere, then you will see results, I was working on a similar thing a few weeks ago. AWESOME JOB AS ALWAYS MAN ❤️....happy new year!.

I was watching the smoke coming out of the exhaust when you were revving it, when it gets to the higher RPM, the smoke decreases significantly, indicating a lean condition. I've raced nitro buggies for many years and this is one of the traits that I watch for during operation, to determine if the tune is correct. I couldn't tell if the carbs on this engine have a low speed and high speed needle, but you are definitely running out of fuel under full throttle, when the engine revs up. You can try richening both needles 1/2 to 1 full turn, and see if that helps....if there are no low speed needles, then it may become too rich to idle properly. The pull through carb that you showed at the end should alleviate the problem, assuming that it's large enough for this engine.

Your original videos on the super charger are what got me into machining and mechanical engineering. It's crazy seeing your videos pop back up on my feed. Good to see you are doing well!

Who else wanna see a rc car build with this

Would it be an idea to put the carburators before the supercharger? That way the supercharger "sucks" the air/fuel mixture through the carburator, so you won't need to worry about backpressure etc.

I was today years old when i found out titanium can ignite!

This is pure lockdown therapy watching these parts be produced in such micro detail.....Brilliant!

Just found this channel and I can already see me spending quite a bit of time watching these videos…. I have an engineering background and served an apprenticeship… I am always fascinated and impressed with the things some people achieve just for fun and to see if they can! Bravo Sir 👌

omg finally we get to see this thing in action

JohnnyQ90's videos: _Peace and tranquility_ PocketNC: *BZZZZZZ BRRRRRR ZZZZZZZZ BZZZ*

You may want to add a pressure tap before and after the carb to measure static pressure. It's pretty easy to use some clear tubing to make a water monometer to operate at those pressures. You can do differential pressure too with that setup. Might help you determine boost issues at different RPM.

I think this is one of the best videos I’ve ever seen, that machining of the parts and the functionality is just so impressive this made my evening 😊thank for sharing that video!!!!!

And this folks, is the type of person who will help us get off this planet. Amazing!!!!

Finally we get to see what the supercharger will do 😭🥺

At first, I was wondering how the exhaust in that little engine would be able to adequately spin the comparably massive turbine. Then I saw the belt and was like "ooooohhhhhhhh...supercharger. Like it says in the title." I see you improved the gearing in a later video. This is great stuff!

I really like the idea man! Also good job, you are definitely skilled in the craft area! It’s amazing how many things you can do with an engine so small.

I would go draw through on the carburetor. you're going to save yourself a lot of trouble trying to deal with boost referencing the fuel pressure to the carburetors that way.

Your machine tools are awesome at a super high level, appreciate everything you do.. Thanks.. 👍

Your design ability and use of CNC equipment is phenomenal I am amazed have a great day thank you for everything

Wow! That is so awesome! Heck of a nice job building all those parts. Thanks for sharing.

For power readings there are two options, 1st you could use a brake that can rotate around its axis and use a load cell or other scale to keep it from rotating the force from the load cell or scale can then be multiplied by the distance to the axis to get the torque. 2nd option is using the engine to rev up a flywheel with a known inertia. Measuring how fast the flywheel accelerates can then be calculated to the power being put in to the flywheel

I’d love to see more on how you get you dimension for your models in cad and how you manage to reference it all so it fits to how it should

Detroit diesel was at this step in the 50s. They addressed it by adding a turbo that was able to compliment the mechanical compression of the sc at increased exhaust pressures. The result was a increased performance across the board, but was later proved redundant. If your able, the history and evolution of the m113 and its variants would interest you. On a side note, I was there to see the changes and what was necessary to get the cummins triple nickle to over 600 hp, fielded in the m2/3, m3a3 variants back in 2001. Those modifications were only able because of the steps your taking. This is Awesome, rock on!

for more torque, make a plenum chamber to calm and prepresurise your intake charge, you can use a bigger carb that way, you'll also need to tune your exhaust for peak power. great project, happy new year!

Super cool, this guy is amazing at machining. Been watching for a long time, super excited on the wankel updates!

That tiny flywheel puller is cool.

I wish I had a quarter of this mans machining skills and knowledge!!

Seeing these rc engines being taken to this level is awesome.

A simple way to messure the power is to add a Brake with a (weight) scale. With that and the RPM you can calculate the power....

The supercharger FINALLY returns... i've honestly been waiting for this :D

Amazing! I am blown away by the possibilities of modern technology.

Great work here @JohnnyQ90. Potentially a simple friction brake would be a good method for determining the power output. They are a very straight forward design and you are clearly more than competent to handle the design and manufacture.

The 2 Rotor engine needs something like this

Titanium boggles my mind- I've known welders that worked with it and people use it at luminous temperature a lot. Cool to see it acted like a magnesium flare-up.

That was a awesome video of the engine and the machining skills and parts that went into building it great job

Something about these videos brings me peace within my soul lol.

Great to see that you are experimenting with force induction again ;) To test the power output, why not use a brushless motor as a generator, a full bridge rectifier, and a serie of big resistor

11:18 Build yourself a scale size Dynamometer Johnny. *That* , in itself, will make for terrific content my friend! Thanks as always for the entertainment.👍

Hey love the videos man they are very satisfying and I enjoy watching them..... No talking an confusing just pure Machining, could u please make a list of all the machines u use to make ur projects

I have a centrifugal supercharger (rotrex) on my 1340 cc twin cam 16 valve motorcycle and found your micro version fascinating. Love a charger 👍

Pls make a roots style supercharger, like a 8-71 blower, that would be interesting to see miniatureized lol

Hi, awesome work! In order to measure power output, i would suggest driving a generator (permanent magnet dc motor). This allows to test the engine with a variable load, and to really measure net power output (volts x amps).

That’s really impressive how you did all this cool work by hand, great job! But are you thinking about putting that engine in like an RC car or something? That would be badass!

bro your videos are the shit. i watch and have watched your content for a long time, and it’s always the exact type of shit i want to see. i love the work you put into it and i love your content, it’s so interesting and well filmed and i’m always so happy to see you post another video. i look forward to seeing what you end up doing with the supercharger man

Try a velocity stack for the feed into the compressor wheel it may be getting starved at high rpm

I don't know how precise it would be but a miniature version of Warped Perceptions 3HP Dyno could work

I don't know much about what your doing but very impressive and cool mechanical skills! Thanks.

Nice you looks like you know what you are doing trial and error is what it's all about, you are the man.

It sounds like its leaning out, you could try running manifold pressure into the fuel tank and riching up the fuel mixture

That engine would be amazing in rc car👍

Just nonchalantly let’s us know he MADE the most badass little pro charger by himself!!. You sir are so much smarter than me and that’s why I like your videos.

First off, I'm amazed at your knowledge and ability to create everything from scratch. Wow!! How'd you get started and what tools/machines do you use? I've been into R/C cars since the mid 80's and am blown away at your creations.

*Μπράβο φίλε 👍* I would be very happy if you saw my vids and remembered your old compressor project 😀 In fact I was inspired by you, when I started my 3D printed supercharger project. I also made a plastic Turbocharger a couple of weeks ago (video will be available soon) and it even made some boost, 19mbar lol 😂 Just to save you some time: swap the 2 small carbs with a bigger one, make some coper piping for intake and exhaust, and a draw through setup. Works great. Good luck! Anthony. P.S. you can use a sphygmomanometer gauge to measure a small pressure. This is what I did..

I don't know about all of you but I'm just here for SHATATATATA

I have no doubt with your engineering skill. Amazing!

Puzzled by your comment about 44k rpm being 'ridiculously low' for a supercharger. Turbochargers often run at well over 100k rpm sure, but my understanding is that centrifugal superchargers, which is what you're trying to build here, typically run at maybe 50-60k rpm. On that basis 44k rpm (at 10:25 ) is not that far from the ball park. What changes did you make to the fuel supply/mixture to stop it leaning out too far in a blow through set up as engine revs rise? Just wondering if the carbs can keep up with the extra fuel needed now that you're cramming more air into the cylinders? Remember also that a centrifugal supercharger delivers more air according, broadly speaking, to the square of its driven speed, so given the relatively high rpm at full throttle (8k), if the engine is running OK lower down the rev range, and given that you have no wastegate to limit boost pressure within the capability of the carbs to deliver fuel, is it being overboosted higher up and leaning out too far. Just wondering. Is there any way you could instrument it with a boost pressure gauge on the inlet manifold?

Great work, i am guessing you can put a DC motor as a load with a load resistor. This will let you measure watts once you account for the generator losses

Happy new year. Draw through carb, bigger pully. Mini hydraulic dyno.

Even tho I'm a fairly new subscriber I've watched a couple of his vids already and I'm amazed at the detail he puts into everything

A drawthru setup would be your best option for sure, I had a truck that also had fueling issues at high rpm

MORE FUEL AT THE TOP WHEN THE BOOST CONES ON...!!!! Best one ever..., just give it more fuel...!!!!

Need more fuel somehow on the top end leaning out on you brother

I was modeling with 3,5ccm off road cars (mostly picco, rb and os speed engines) for years and i'm pretty sure the engine runs rich in lower rpm's but leans out in the top end as the forced induction produces boost. So lean it a bit in the lower end (small needle screw in the carb) and richen it up a bit in the upper end (big screw where the fuel nipple is located)

Amazing engineering! Great job man

Warped Perception had a pretty sweet setup for testing his turbo's engines, I don't know if it would scale down politely tho

Amazing!! Johnny you would like to see my homemade 1/5 49cc RC car!

You are a talented engineer and fabricator.

this is super dope man congratulations

The Alpha Mod and Johnny Q90 collaboration коллаб альфа модс и джонни Q90

Impressive machining! I think you may need an electric pump and a regulator that senses intake pressure/vacuum in order to maintain proper mixture throughout the rpm range. It seems to be leaning out on top end despite the pressure tap off of the exhaust. Either that or a draw-thru system, and use a single larger carb on the supercharger inlet.😉👍

Love these small engines the work is incredible 👍

That’s awesome excellent execution, sounds like she needs more fuel the air to fuel ratio is super lean at higher RPMs due to increased air flow from the centrifugal supercharged. That will eliminate the break up in RPMs at WOT. Good luck and would love to see another video on this.

To measure the power. Make a heavy flywheel and measure the amount of time it takes to get to a set rpm.

"AWESOME"

I wish this had a full exhaust system and was inside a rc scale crawler our drift car!!💯💯💯 thanks for making this video bro

I used similar tachometer in my garden tractor engines. I think they are pretty darn accurate

I don’t know if this has been requested before but I’m kinda interested in a voice revealXD

MORE FUEL! :D

Nice fab work and very cool video I look forward to seeing the next on this

for power measurement, can use a line holding weight that winds up on a spool connected to the flywheel. add/remove weight, integrate over a known time, you'll have power/work and be able to determine the bounds on instantaneous energy.

Make a miniature engine dyno based on an electric motor and variable load!

Try and build a roots supercharger dor on of those small engines

For a dyno, you can do this a couple ways.. you need a load cell for starters. Size appropriately to expectations. Then you can either machine a waterbrake. OR, get a good ole brushed motor and couple it to the crank of the engine. Attach your load cell and either a suitable rheostat or adjustable carbon pyle load and start shorting the motor to increase load. You also need RPM reading to calculate hp. It's a pretty simple thing to make a dyno brake. There are so many ways. Hell, if you made a belt driven copper platter and put some neodymium magnets near it, you could even use eddy current to brake it like trolly cars do. Closer the magnets get, the more brake you get.

m8 your a true legend you make the coolest things

Think the fuel pump pressure is too low once the engine reaches peak RPM’s? Just a thought. Nice work as usual!

Sounds like it chokes..... not getting enought fuel at high speed..?

If you could make this, you could make anything. Great job!

Keep it up bro, no limit to innovation. I’d like to see more.

A you tuber “warped perception “ came up with a reasonable engine torque measurement device. Check it out.

Thats a turbocharger

go on bro its awsome!! and do check its power after all and do a video on making a really supercharged rc car with everything u can add!!🤩🤩

This issues with it breaking up at high rpm can likely be fixed with a fuel pressure regulator, so that the fuel pressure stays the same relative to the boost pressure

,,,,,Yes finally the return of the charger And happy new year to everyone reading this,,,,,,

Awesome loved it. Great vid brother.

This is what we call Art a bright masterpiece.

Man... You make the coolest stuff! 🤠
