Finally, a supercharger for my Honda Civic.

I bloody love these videos quality over quantity

1.5 psi is actually quite alot running through a nitro engine with such a small displacement

Small brains: "oMg iTS a TurBo not A sUPer ChRgeR!" Me not so big of a brain: wow a centralfugal charger for me vacuum. BTW I can't spell

*Mom from the other room* "Why are watching a video of a vacuum cleaner?" 🤣

Been in the turbo industry for a long time and I was about to say... for max efficiency, ditch that 90. Air does not like to be forced past 19-22 degrees. The Japanese knew this.. that’s why their bends are wide and smooth on their most powerful setups...2JZ/RB26/SR20 etc... we also use Venturi stacks where we can in the intake side to avoid step face eddy’ing. Your videos are amazing and I love your attention to detail.

First off: u are a true master of art/tech. So my input is same as others have said, u need to seal housing as ur loosing pressure somewhere on there. Second u need a miniature blow off valve to keep pressure in and release as throtle goes down. Just those 2 things will raise the boost as it is. Looking forward to part 4 with sugestions. Keep it up john. FYI, i would buy a setup like that just to keep on a desk and turn her on to hear spool up and blow off valve. That would make an awsome desk prop... let us know...

It’s obvious you have a talent for machine work. It’s so fun watching these kinds of videos. The dedication you have is fantabulous and can’t wait for more. Great job. 👍🏻👍🏻👍🏻👍🏻

Wether it's going to work or not, it's all very interesting to watch! Stay motivated!

this is why guys with machine shops don't hate their life like the rest of us!

No unnecessary background music, detail picture, satisfying content and execution, great information during video. Glad I found this gem :)

Watched 10m of the video just to smile at the sound of a mini supercharger

“In today’s video I will make a supercharger out of spare vacuum cleaner parts” Johnny:” hold my beer”

"everything has to be perfect" that's awesome no cutting corners

Again as a machinist myself - you do just outstanding work - I mean damn outstanding work

Keep it up, Johnny! I've never seen someone with machining skills like yours. And btw, that's already quite an impressive amount of boost for a supercharger that tiny.

When i see, "johnyq90 uploaded a new video" i clicked as fast that i can because im so excited about your mini turbo i love turbo and miniature things😍😍

What ever the results are, your work is awesome

Thanks for posting an amazing video. I’m a teacher and I teach auto mechanics at a Career Development School in the United States for kids under 18. My students love you!! I had one of my students show me your page and now we watch two of your videos on Friday if they’ve met their curriculum goals. Thanks again and keep up the good work!

This is the first 15 min vid I've EVER watched from beginning to end... cant wait to see the vid on the mods! Hella job bro

I just had to see this one !!!! That was freaking AMAZING 😍!

Very well done sir! I'm shocked by everything, the quality of your video's, your tools, skills, commitment, ...

This is simply amazing!! I just found this channel yesterday and am glad I did! keep up the good work!!

😂I love how everyone thinks its a turbocharger when its not

Guys. First of all, thank you all for your kind and positive comments. It really means a lot. To the point though: I need someone to describe with detail the device that I need to make in order to measure the pressure correctly. I imagine some kind of container with the pressure gauge attached to it, instead of having it exactly in the outlet of the compressor. Something that I can fabricate easily and actually work. I want to do this before I actually jump and make any of the the modifications that I mention in the video. You can also share the video with your friends, so more opinions drop on the table ;)

Something to take into consideration is that this is currently making 1.5 psi of boost without the nitro engine acting as a vacuum sucking in air in through the outlet. As others have pointed out I think this thing is going to need to produce a significant amount more of rpm to make effective boost while on an engine. Looking forward to seeing the next update!

I'm more than a little envious of your shop and skill!! OK, on second thought, I can go and BUY a shop like yours. But, I can't buy skills like yours, so, I'm still envious!

This is by far one of the best videos on UKposts. It may never be functional but you did everything you could to ensure that it would be.

The PSI gauge shown is not one you should use to test your supercharger pressure. It has not been calibrated and not setup for flow throughput measurements. It's designed for containment. What you're really after is volume measurement, or cubic centimeters per minute. It might be possible to adapt a small car engine Mass Air Flow (MAF) sensor and read the voltage differentials using an Arduino Uno board. I've seen several makers successfully make one. Your impeller design looks very good for the size and volume required. Adding directional vanes should not be necessary. I do agree with your decision to remove the elbow. Thoroughly enjoyed watching this episode!

jdm car channels: CRAZY RX7 FD **2.3 HP** **1.5 PSI OF BOOST**

You have great skills. I appreciate the lack of music. Keep up the good work

Impressive build! 👍🏼👍🏼👍🏼

You should try using ceramic rc bearings without a rubber sidewall. That should help a bit to reduce resistance in the system

You'll get it, keep going don't stop, amazing videos as always !

My interest is definitely peaked! Keep going, you'll not be disappointed!

Love the work you do, the detail pays of with your patients!

I love watching your engineering videos man keep up the good work @JohnnyQ90

put an venturi stack at the inlet , it helps a lot ;-)

Small engine mechanic, 27 years here. Ive seen it all, but i see improper lubrication and cleanliness the ultimate factors. It truly astonishes people what 1 grain of sand can do.

I watched like handful of your video, after this one I was just jaw-dropped and so I subbed. You are talented and a perfectionist my friend!

This series is phenomenal. You’re an impressive chap, keep going!

Based on apparent pulley sizes, I was gonna call BS on 1:8.......then you showed me the gearbox. 🥴 🙏 Awesome execution !!

More then enough reason to support you. That is some fine work you're showing there!

This is an amazing Achievement Can't wait to see you perfect it

It's so cool to look at your skills progressing. I remember when I saw your videos for the first time like 5-6 years ago. looking at what you do makes me want to buy a lathe and mill :D Keep your turbine spinning dude. ~A lathe enthusiast.

You need to increase the diameter of the turbine wheel base in proportion to the inlet diameter. A majority of the energy from the impeller is imparted to the fluid (air) at the outer edges of a turbine wheel. The further away the blades are placed from the center of the axis of rotation the more energy from the motor the turbine wheel will turn into air velocity. By the looks of it there is plenty of space in housing to accommodate a larger diameter turbine wheel.

DUDE! Your design and machining skills are amazing.

You are a MASTER! There are no mistakes, just lessons! Keep going! you are doing great!

You do some rather nice work. I'm very surprised that the gearbox held up as well as it did during your testing.

This thing on a RC car would be awesome!!! Will the wankel-engine be installed in a RC car? Very good video as always! Keep up your great work!

Love this setup! Beautiful craftsmanship! Cheers from Australia! 😊

DAMN! I've just, moments before clicking comment, realised I'm now commenting on a one year old video! However, what I was going to say was: Dude, this is seriously impressive engineering, you built your own gearbox, which has proven itself reliable operating at 135,000+ rpm, this was to drive your own centrifugal supercharger, the volute for the centrifugal supercharger with the elbow etc is a very nice piece of multi axis-machining. I operate at the other end of the scale - fixing oil rigs - but I am genuinely impressed with your talent. I don't think you'll see much gains from taking off the "turbo" elbow, the real gains will be in tightening the tolerances between impeller and volute, although removing the elbow will reduce flow restrictions, increasing the "head" with which your "fluid" (air) hits the gauge possibly increasing the reading, but not necessarily indicating any more flow and flow = power in this context.

spectacular your work, once I saw that made a 4-cylinder turbocharged engine to scale has something like to see it

what an amazing Supercharger...we look forward to seeing part 2...job well done!

I subbed this is the most badass thing I've seen in a while u r a machinist master my friend what u r building is just plain badass

Keep up the good work would love to see it work for an RC

Nice work man, enjoyed watching. You have good engineering skills and eye for detail. Quality craftsmanship gets my subscription.

That gear box held up well! Good to see it. I know you will get the rest sorted. This is such an amazing project! :)

WHEN ARE YOU GOING TO MAKE A WHOLE ASS COMPLETE ENGINE? I BET YOU CAN DO THIS JHONNY!!!

This is brilliant. We appreciate your strive towards perfect. If these aren’t perfect then they’re damn near.

Keep doing what your doing man! Great content! 👍👊👌😎🍻

Maybe, you should try to lower the section of the ejection vents. That would increase the pressure for sure.

Absolutely •love• your work on your project, JohnnyQ90, and everything about it. So happy to see someone putting some major hours into R&D’ing into functional means of forced induction for an RC Wankel (or 4 stroke!) engine. I have owned, tuned, and loved the OS FS-120S-SP Roots super charged engine for many years... I hope with the advent of your design and work, more will follow - and one day I can own a functional supercharger for my FS26S-C powered SuperTen. Keep up the great work dude, you’ll get your setup tuned out and where you want it. Much love! -j.

This is really awesome stuff. Thanks for sharing. You have inspired me to learn more about machines and engineering. Maybe new materials technologies can make applications like these more cost efficient/practical. We live in very interesting times and I am excited about the solutions technology might provide. I have read some about the Bernoulli Principle and atmospheric pressure. Good luck figuring your project out. I had wondered when I first saw your video about making the impeller if the “laws”/phenomena are a bit different when considering proportions.

You are truly an amazing UKpostsr I’d like to see you make a turbo that runs on the gasses of a nitro engine .21 size and up keep up the good work mate I’ve been subscribed for quite a while now and you never disappoint 👍

136k rpms is not enough. Your wheel tip speed needs to be max 1,400fps/427m/s. I suspect your wheel will be above 300k rpms to make effective boost. Great work!

Im so glad i found this channel. This is def the best channel on youtube

hours i spent with vieuwing your posts it brings me in my confort zone when im home alone ! respect for your pressision !

I think some collab between Johnny, and Bad Obsession Motorsport would be freaking amazing. Those gents are legends of engineering.

You should put the carburateur after the compressor, at high speed fuel drops can damage the impeller

Incredible you have this type of knowledge

Looking forward to the final version of the supercharger... Good Luck Bro...!

When u said we are your motivation i felt like you are my motivation! Im an old subscriber i gave this video a big like.

Been waiting for this! Clicked ASAP

Great video and awesome work machining that! At 8:16 when you use the bottle to lube the gears, some metal filings come back with it. something that spins fast and requires a good seal should be mega clean when it goes together. if you put a radius on the face of the compressor intake ID bore, or even taper it from where it starts, you'll have better intake airflow!

this was exactly what 11 year old me would dream to be able to do! I love your videos and projects man! So talented

Kawasaki engineered one of these for the H2.... 130k rpm with floating ceramic bearing. Impressive.

You're not really looking for static pressure... Just a higher pressure at a higher volume

I have to admit I'm really impressed I have never seen such fine machine work and planning my life you've done a great job I'd love to work in your shop but at this stage game I'm 69 and then instead of running with the big dogs I sit on the porch and bark have a great day

Amazing work...can’t believe how good you are!

You can vaguely hear compressor surge when the gauge is on, you need make some boost pipes to see what it can really do

2:19 - so satisfying watching that bit at 2x Speedo dunno why 😆

Wow ive never seen a supercharger that looks like a turbocharger but the craftsmanship is amazing good job

What a work of art brother! Watching the thing come to life was very satisfying hehe!! Too late to give my pressure instrument reader idea off to the next video

You see all these ASMR things with sand and slime. Man's watching microsupercharger asmr.

I love to watch proper threading

You got mad skills my friend!!!🤘

please keep up this work! love it

Can't wait to see it on a RC car. Are you making a mini BOV?

Insanely great content! "My motivation is YOU" I've never hit that like button faster =D

Oh man I just found the next upgrade for my motorized bike!!!! I would buy 1 right now if they were for sale. By far the coolest supercharger I've ever seen.

Insanely awesome. I can’t wait to see it all together one day. This rc car is going to be epic

"My motivation is you." Come on man, you can do it!

Strap it to a nitro engine and wind that boost til it blows

You can do all this amazing engineering on such a tiny piece of machinery! I would love to see what you can do with full size components! Amazing 😁

CARA VC È UM MEGA GENIO NAO TEM NINGUÉM NO MUNDO TAO DEDICADO ASSIM

Awesome video, what i can't fathom is that there is 1.8k people disliking this video. Maybe they're just jealous they can't think of anything to do with their time.

This project is mind blowing man ! I was wondering if you've planned an intercooler in the system :)

Brilliant design and work my friend!!
