Micro Supercharger First Bench Test | Part 3

[@johnnyq90]

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 ;)

[@xibidit]

well what i can think of is to have a container that "leaks" slightly, the boost pressure is just a restriction measurement, the air that hasnt made it inside the engine yet. i think you need flow as well as a restrictive container. im no scientist you already know everything i have to say =) hope you get it right though because this is amazing content

[@johnnyq90]

@@fdloop kzbin.info/www/bejne/l6jGqZSZrLKlkLc In this video, I show a 3d printed mock up of the compressor housing and how it will be installed in the engine exactly. Go to 0:45 to see exactly what you need.

[@samuraisystemsllc]

Here's a pic of the general idea. The blower needs to be able to pass air through it, then manometers are used to measure pressure in the air stream vs. ambient pressure: dataconeengineers.com/products?id=1154 Just one homemade manometer in the output tube is all you need, then restrict the output after the manometer with something adjustable, a flap valve or just your finger, to adjust the output restriction to a realistic level, similar to the restriction of the engine's intake.

[@nicholaswilliams4507]

DIY manometer. Plenty of details and resources on the interwebs.

[@craigapple3185]

Not saying it's a huge problem, but... The China guages are hit and miss, I've used several some are dead out of the box and most don't match up with each other I.E. one reads 5 one reads 3. People are also confusing boost. Boost is a measure of engine restriction. If you setup a valve and open it boost will drop, close it and boost will rise. This equals engine volumetric efficiency. Full flow no boost, closed valve, turbine stall? The other thing I haven't followed closely enough is if the compressor is or should be sized to the engine...I'm sure you can calculate it , I'm not familiar with doing so on a Wankel. Then there is controlling boost...another ball of wax. Mini diaphragm waste gate!!!

@@Q50Diaries That's what I mean, 1.5 PSI is low boost, whether it's a 10L or 10cc engine.

[@GeneralNOH]

@@soupisgoodfood42 Well, sorta. It's proportional to the volume of air its delivering. At 1.5PSI (above atmospheric) whether its a little motorbike engine or a 6.2L v8 you're still adding ~10% more air and thus 10% more fuel at a set AFR, and in theory 10% power. But in a bigger engine, you're obviously going to gain more power for every pound of boost; Lets say you have a 2.5L engine and a 5L engine, in theory, your going to gain twice as much power on the 5L engine for each pound of boost you feed it. So 1.5lb of boost is not much even on a tiny engine

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.

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

[@connornorlin]

Ceramic requires more oil and may need a oil feed , ball bearings are better for smaller applications , it would probably work bit be much more difficult

[@connornorlin]

@Eclipse538 no ceramic bearings use a thin film of oil to reduce friction ever seen a ceramic turbo run dry its destroys them

[@connornorlin]

@Eclipse538 and the oil just helps a little some turbos have seprete coolant lines

[@boostedjdm185]

I’ve worked on hobby grade model cars for a couple years and have never heard issues with needing loads of oil for these bearings and certainly nothing about needing any kind of oil pumping system.The reality is that the engine wont be running for super long periods, so they can be oiled between runs if need be. Ive seen people upgrade from metal ball bearings to ceramic in their RC drivetrains for racing, the primary disadvantage being that they are more delicate. I wont pretend that I’m an expert, but in my opinion he should at least experiment with them and see what works. 🤷‍♂️

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!

[@GarySmith-up1un]

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

[@DougHanchard]

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!

[@christianzuger6253]

I agree. With the setup like this 12:56 the charger is running with 0% massflow and chrager are not designed for that point of operation. You are sitting on the surge-line. A characteristic can look like this: content.mynah.com/mimic-webhelp/Content/Resources/Images/simulationstudio/blocks/adv_blocks/Compressor/Axial%20Compressor.png Imagine: There is no air going in-or out the charger. So there is no moving air, its just sitting on the blades and rotates the same speed as the rotor. If so, there is no air-friction-resistance that could push against the sensor and the hole supercharge is running in no load.

[@DougHanchard]

@@ferch4846 it's been my experience, with small supercharger inlet diameters (less than 30 mm), the need for an intake runner is not necessary and does not make a significant difference. One likely reason is the air density ratio does not significantly change. In fact, it will actually create a restriction given the low negative (low pressure) atmospheric conditions. Large 50 to 120 mm diameter intakes can leverage a intake manifold design because of the volume of air and design of the impeller. Belt driven superchargers like the Paxton work well without a precision air horn. These were common modifications to Small Block Ford 5.0 liter engines installed in a cramped engine bay.

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!

[@wnodzykowski]

Agree, you are way outside of the max efficiency zone. 130k for impeller this size is nothing. Try gearing it for higher RPM (at least 300k) first, then look for improvements. Overall amazing job, always pleasure to watch :)

[@timesthree5757]

What? He doesn't even need to produce that much boost for an engine that size to increase engine power.

[@joekirian3657]

If you guys do the math, assuming the wheel has a diameter of 25mm, then for it to reach a tip speed of 427m/s, it needs to do 326,214 rpms. Diffusor wedges are good, but will limit the efficiency envelope to a somewhat small range. Bladed diffusors are good at pressure recovery when ran at the calculated design point. Once you get off that, you'll start getting flow separation and efficiency/ pressure recovery will drop, worst case it'll send the compressor into surge. If you plan on using the engine in a plane that will be ran at a constant 75%-100%, then use the wedges. If it will be used in a rc car, stick to a bladeless diffusor.

[@timesthree5757]

@@joekirian3657 The other thing to remember is that downscaling increases efficiency. I think he will be fine. Even a small amount of boost will produce large gains in power.

[@ADRIAAN1007]

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.

[@sergeykrukovski4011]

First it's kind of difficult, it other words means a lot of work to make a bigger one again. Second, there is an optimum of efficiency depending on the wheel diameter with the same airflow. Sometimes it's more efficient to have a smaller compressor wheel which spins faster. I'd really advise to calculate an approx airflow and the corresponding wheel parameter at least in a simple way, for example using VistaCCD app.

[@ADRIAAN1007]

@@sergeykrukovski4011 I agree with what you are saying, however at this scale all turbines are inherently inefficient. However a small turbine can only move so much air at some point speed becomes irrelevant and the only way to increase flow is by using a bigger turbine.

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.

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

[@petehodges7711]

DUDE! Your design and machining skills are amazing.

[@exposingthedarknesswiththe9190]

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

[@pheonixprime8]

Its actually a turbocharger

[@dkick809]

The Michael Roberts actually its not. It’s a centrifugal supercharger. A turbo uses exhaust gases to operate and a supercharger like this on a motor is turned by the crank or it can be belt driven.

[@ploufdanslac3193]

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

[@Med1na2012]

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

[@eliaonnembo699]

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

[@angelhills5615]

elia onnembo That’s interesting and incredible men

[@sockmonkey6666]

Remember that at that scale the air is much more viscous, almost halfway between gas and liquid. you have to adjust the design to account for that or you're gonna get cavitation effects and turbulence. Looking at the way water turbines deal with it would help.

[@aidanf2610]

Cavitation in an air compressor? I don’t think so 🤣

[@sockmonkey6666]

[@aidanf2610]

@@sockmonkey6666 is cavitation possible in air?

[@sockmonkey6666]

@@aidanf2610 Certainly. Anything moving fast enough through the air can create a vacuum bubble behind it.

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

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

[@thtsnglcab7.33]

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

[@rcwreck-creation]

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

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

[@mikemcinnis12]

You should seriously consider doing an EFI conversion, the benefits would be huge as you could much more finely control the fueling, on top of being a lot safer for the engine you will be able to optimize power, There are multiple different RC EFI conversion kits that replace the carburetor and come with all the sensors/harness needed to run it. You might have to make an adapter plate to get to fit but from what I seen it looks pretty generic in size, I'm not too familiar with R/C stuff so I don't know if you are using a generic sized carb. Also you would need a MAP sensor to be able to read boost levels. Worth looking into and I think you could learn a lot playing with EFI!

[@RUFU58]

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

[@kevinstenson5747]

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.

You may not be my brother, BUT BROOOOOO, you need to do this, this project is insanely crazy cool!!😍😁😁😁 I always wanted to build one myself but i can only to the CAD files, need someone else to build it then. Thought I lost my old files, which had a tolerance of about 0.01mm but I would want something more like 0.005mm or 0.004/0.003mm so that there is literally no way for coolant (oil) or air to escape through the meetingpoints of 2 parts, i guess I'll be calculating a lot in the next few weeks ^^ maybe months as this would be a sideproject for me ^^ but I would make it to run on motorBikes/scooters or bigger RC fuelengines ^^

It'd be cool to see you squirt nitro in the intake and ignite it on the way out. Though, that'd likely damage it, idk

[@tommygilbert2648]

You should put that on to the RC Mini four stroke motor

[@BaoNguyen-un1km]

Now you have to build a blow off valve to protect the supercharger against surge

[@zheneggmobile]

not needed with centrifugal blower like this. if it was a positive displacement blower like a roots type, then yes

[@Scientwisted]

A tip for your belt tensioner, ALWAYS have the tensioner on the trailing side of the belt, so as that the motor/engine has the belt taught and not trying to pull the tensioner pulley out of place. At 9:20 you can see the belt at the bottom flopping around, that's the trailing side and needs to be kept tight or the belt can fly off. All belts on cars use this principle.

Awesome work man!!! keep in mind that you should test this on a safety plexiglas box or mount a camera and control it from distance. you could get injured very bad if something goes wrong at those speeds.

[@MazeFrame]

Amazing! I hope you dont kill the engine you put this on.

[@Elios0000]

id put the carb on the intake side of the super charger this will help cool and lube it and was pretty common with radials so should would with glow fuel yeeah you cant judge boost with out intake from the engine as well as the carb will be at nearly 1bar to start with so you should get maybe 1.5 bar out of it it also may just need a LOT more rpm do to the small size of it and i mean a LOT more like 2x or 3x may want to think about making another scroll and making it a true turbo if nothing else itll "super normalize" the engine the YS line of engines are super charged with crank pressure from the back of the piston should take a look at them :D

[@miralemnermina142]

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

[@the_car_guy5915]

Now make a turbo and twin charge the same engine.

[@hjooy]

Forget about the items in your plan: you first need to improve the shape of the impeller blades...

[@roccobro]

And contour the inlet of the housing. Needs to be more funnel like and some kind of trumpet/horn flare if going to be run without piping to the inlet.

[@kedwa30]

Better to start over, making it larger diameter and thinner.

[@drewmania6034]

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

[@ollilehtonen6764]

Johnny, when you manage to optimize the turbo/supercharger, put it onto a rotary RC. Preferrably twin rotor

Did you actually made the calculations to make sure this would be the correct size everything for your engine?

[@NBrogdon45]

Based on the sure genius of this man I would think he did! Doods skills are out of this world!

[@fullmetaljacket7]

Nick Brogdon he didn't. The impeller is way too small.

@@fullmetaljacket7 I don't think so seeing as this keyring sized charger produces 1.5psi... in scale that is A LOT.

@ It's literally nothing. That's just static pressure. Pressure without flow is useless for this application.
