@@fortj3 aliexpress would do for some stuff ebay for the rest and an electronics shop for stuff like the potentiometer. If you are going to build one though you will need to run serious battery power. The phantom and torqamp use 48v at a minimum so weight will be an issue. The torqamp is capable of around 5pounds of boost, the issue is given the battery needs to recharge its not as convenient as a turbo. You will need to know the amperage needed as well as the voltage. I'd be really interested to see what this kind of motor would do with something like 96v If you want a source for powerful motors look at the guys who are modifying powerwheels/making adult. Power wheels. I really wouldn't use the type of power system this guy is using. 1 because the performance won't be great at only 12-16v and secondly they are really finicky with charging, lipos are great batteries but if they are run dead they die and heat or penetration or temp fluctuations can cause the batteries to expand and puff up and at times even burst into flames. I use lipos a fair bit but they are something you have to treat with respect. A conventional li-ion battery pack at 48v which is essentially something similar but smaller scale than an electric cars battery pack isn't going to be that large. Certainly small enough to install on a motorcycle

My thoughts exactly. It would fit beautifully under the airbox of a vrod, vmax, or gold wing. Me owning a vrod would love to have an "homemade" supercharger cause everything on the market costs 6k up.

I'm an RC truck guy and I am very familiar with all the components of this, this is a very interesting concept and I thank you for shedding some light in this area I do believe this is doable and may just have to take apart an old RC of mine and see what I can come up with can you say 6 cell?? 👍

My university work was exactly that. From the calculation that I make for 0.7 bars of pressure you need around 10kw of power. And this won't work ideally in the car engine. F1 cars are using 40KW electrical motor to power the turbine in great pressure over 1 bar. Your initial test are maybe little bit unpolished, but if you plan to have practical use, better think about the design. The bearings won't last long and the motor need cooling. Ideally hydro bearings are the best and water cooling for the motor. In constant work the compressor section also will get hot.

As electric motors that can turn 100,000 RPM or better become available, your idea will work. It will take a lot of power to turn a feasible turbo compressor for enough usable boost. The electric motor would need to be 20 HP or higher.....

With mass implementation of 48v mild hybrid technology these electric superchargers become a reality these days from many of big brand car manufacturers. Check out info about latest Mercedes engines - they use similar setup to help turbo spool.

@Chris McRoy The electric motor driven turbo runs until the ENGINE is above 1800 RPM where the turbo begins to spool.

how did you attach a motor to the compressor wheel ? i am trying to build a smaller version of this ( have been for a while ) and instead of batteries, going the super-cap route. As of this comment, i have 1900 FARADS , and simple math seems to show about 3500 FARADS would be enough for 20 seconds of boost. The super-caps are light weight, and need a dedicated charge (boost circuit) board, but eliminate any concerns for lithium cells. back on point, aren't most compressor wheels 6-8mm ID shaft? or may i ask , what motor do you use/recommend ? your setup is awesome.

On this little thing, it was a set screw on the motor shaft. On the bigger ones that actually made real power (you've probably seen one of my recent videos where we dyno'd the "sledgehammer" on the car and made over 530 rwhp, but if you haven't it's here: kzread.info/dash/bejne/gp6DrLdpYqmvd9o.html) I've had the most luck using a "hex" drive - basically a modified impact socket driving a bolt threaded into the back of the impeller shaft. I did make some videos about that a while back: kzread.info/dash/bejne/p2mdm49xg7u7lKQ.html My thoughts on using super caps: I think you'll be disappointed in their performance in this application. The major reasons are they have a low power density and the biggest reason is their voltage discharge curve is linear - pretty much straight down at a 45* angle as they discharge. Lithium cells then to have a "flat" discharge curve; well, a lot flatter anyway. FWIW, I did actually buy a giant supercap assembly to play with - it's designed for starting diesel trains and semi trucks. I've got a video on that thing somewhere on my channel too. Maybe that's a good video to show how much the e-turbo would slow down and how quickly it will do so. I can use my small e-turbo to demonstrate.

The energy recovery units in the current F1 cars are basically brushless motors hooked up in between the exhaust and compressor side of a turbo to be able to both charge batteries for the KERs system, and spin the turbo up quicker as a form or anti lag.

Have you thought if gearing the motor. 2:1 it would spin the compressor at up to 120,000 rpm?

Small turbos like these are fitted to small 3 or 4 cyl. engines. The compressors run around 100.000 to 150.000 RPM or even more. Even larger compressors for larger engines run around 100.000 RPM to give enough pressure. An engine turning high RPM uses a lot of air... For crankcase evacuation it's probably going to work.

A set screw doesn't seem like a good choice. Did you at least put some thread compound on it to keep it from walking out? Pressing it onto the motor shaft might be better, with a tapered pin?

use a plastic impeller/fan with closer tolerances, plastic housing, heatsinks on motor housing, and an high power RC drone motor. That design is for and exhaust manifold setup. Even a Dyson motor might work.

A while ago I did one too. But I geared the motor up by I believe 2.3 and used a larger motor at 6s. Theoretically it should do close to 100k rpm. I got 0.3 bars at zero flow. No idea what amps it takes, but a 100A plane esc gets pretty hot.

AlexLTDLX, You really should re title this as $100. crankcase vent, intermittent use only.

I love the miata shout out, ive been wondering how I could implement this setup in one. Id love to know what kind of weight a full system takes, and how hot the air coming out is, I was thinking it could be used to compound boost a large exhaust driven turbo at low rpms. it would have a bypass that opens once the tiny electric turbo (id go even smaller) cant supply the bigger turbo. this could in theory installed in a number of different places that will have lower intake air temps and heat soak than directly in the engine bay.

Nice work! well thought out and for what you want - seems very doable!

to test the pressure side you need to route the flow into a container that "leaks" so it has a small hole so it doesnt surge (like an intercooler-like container with 2 inch inlet and maybe 0.5 inch outlet into the air) otherwise it is just surging and you wont get a reading at all

This, overall, is a great proof of concept and way to test the theory. Now, given the funds can be had, this'd be worth sizing up to something that could boost a K20 or K24. But we're talking in the $2500~ range for a motor like that, but I've missed out on the last good 6 years of RC hobby, so don't quote me on it. I started building real race cars instead, and surprisingly, spending about the same amount of money. Go figure.

Yep - that's the point I make in the video. And why load goes up (current draw) with the inlet and outlet open to the atmosphere. What's really neat is that you can feel the air getting warm from just the compressor's internal compression.

A turbo on an engine spins fast ALL the time. If the turbo quit spinning it would just clog the intake. When you're electric motor is off you're engine is dead. Like other comments a turbo functions using the wasted exhaust heat to create additional power, and it's inefficient, the turbo heats the air up and loses some of the power as well. You'd be much more efficient by attaching the electric motor to the front of the crank shaft and directly adding the electric motor power to the engine.

He said that motor is 5000 watts. One HP equals 746 watts so that is about 6.7 HP. To have a realistic electric turbo that will produce boost all the way to the car engine's redline I would think 20 HP plus is needed. On a V-8 engine it would probably need closer to 50 HP and 100,000+ plus RPM brush-less electric motor. But I do believe that in the next few years, that will be possible. Top fuel dragsters use a supercharger so big it needs 900 HP to just turn the blower. I am not comparing anything here but it does show how much power is needed for forced induction.. Here is a setup similar and lots of details if this person is credible.. kzread.info/dash/bejne/qZhtpdCPeLXKgaw.html Here is a deep dive into this topic.

Ive always wanted to do this. I believe the 80A rating is phase amps. Draw on the battery is much less. Yes nominal is 3.7. Don't allow the battery to drop below 3V or above 4.2xx per cell or you get fire :) The problem is that turbo wont move much air. Check out hobbyking. They have helicopter motors that have a very high KV and some that have watercooling from the boats.

awesome video. i hope your doing a series of this :)

This would definitely work !!! finally a not crappy electric turbo

I always knew it could be done -- but people always scoffed at the idea. I just wasn't thinking small enough (RC motors, controllers, and batteries)

Alex I think you have the right idea.. I bought the same turbo but abandoned the idea.. But I don't get why people always try to use 3s or 4s. I run my ebike on 36s.. You can get ebike controllers that can do 150v FOC connect that to one of those big ass turnigy motors that replace 150cc motors. Connect it to a T3/T4 Turbo and I think you can get some serious air flow volumes and pressures. You just keep the pack in the car some place and charge up every 3-4 passes.

Just to add.. the point of this vs getting a regular turbo setup would be simplicity.. You just connect up a turbo to your throttle body intake and you are set. No oil. No water. No Manifold. Just boost. But you need a big ass battery pack :)

So how much boost do you think this will produce after you overcome the vacuum of the engine? I don't think this will work

If I close my eyes it sounds like my wife blow drying her hair!Lol🤣🍻

Yo, to get it to 80-100k rpm just do what aircraft do, gear reduce the compressor. You could have kept the original shaft, attached a small gear, milled a plate with an attachment for the motor offset with a bearing for the compressor shaft and gear set that can bolt on to the original flange

This is really brilliant work. I would have thought that drilling the shaft with an electric drill and then adding a setscrew would have destroyed the turbo balance, but... the proof is in the pudding. It worked. I guess that since all of the disturbance was very close to the axis of rotation, very little dynamic imbalance resulted. Fingers crossed. I also would not have believed that you could suck that much power, that quickly, out of a lithium ion battery. I know that lead acid does best at about a 20% discharge rate. Li/ion is probably twice as good... but jeepers. You almost need super capacitors to run this thing. However, it did work. You might find that working with a larger capacity battery might allow the motor to draw even more amps; I suspect you're being limited by the maximum battery draw rate. I'd really like to see good numbers on the static PSI boost; as you said, holding the boost gauge on the end of the turbo isn't going to yield reliable numbers. This is really, really excellent work. Just brilliant. I look forward to your further implementation! Very, very nice. >Charlie

Deadheading it brings that surge limit down, it would be better to figure a way to simulate a loaded condition. Great idea to use it for crankcase evac!

Mill a housing that could hold a gear multiplier then attach the motor to that. Those RC car sometime have a 2 stage trans for high speed runs.

The fact that the esc is much cooler then the motor indicates not enough motor load. Which can be remedied with taller gearing or a higher kv motor. ( Provided the battery and connections are rated at or above the esc max draw and its rating and wiring is at or above the motors max amp draw. ) Then a over geared setup will make the esc hotter then the brushless motor . And a under geared setup will make the motor run hotter then the esc. When both run at a even tempature within the safe temp zone it will be at maximum effniceny . But 100° F is well in the safe operating tempature range. Brushed motors hit the danger zone around 150F and brushless motors exceeded that safely. . Nice experiment 👍 I've been thinking for a while now that the correct bl motor/blower setup could actually create boost . Possibly even a 6-12s brushless EDF setup ?

Wonder what would happen if you ran an electric motor that is driven by a gearbox off an engine driven belt geared sp that it spins at its proper rpm. Then run its wiring into the motor on your charger? All a motor does it turn electrical energy into mechanical or can also do the same produce electrical energy from mechanical work. So my theory is that if you use the same motor, spun by belt and geared for the correct rpm, you'd be able to remove your batteries

Check out the Torqamp and Arc Superchargers, they already make this and theirs hit 8psi with lipo packs. Plenty for small engine anything from a 3-6 cyl will benefit at lower rpms. Provided the displacement is low enough. I would say anything up to a 3.5 V6 would be fine. But at the top of the rpm range you may end up choking such an engine.

Have you seen them people turn old alternators into motors for go carts and stuff its basically removing the diods and regulator and a 3 phase esc but one of them with a belt I assume for rpm and a little bigger turbo for some small boost

You trying to make boost for power or just for Crank case ventilation?

Cleetus is no scientist. Bottom line is engine displacement. Even a leaf blower will build some boost and a genuine engine blower will restrict boost--yet boost can only be achieved only if that blower can produce the cubic feet per minute of air which exceeds that of the intake of engine at rpm. All it takes is a little math for engine running at 5,000 rpm: 2.0 liter engine = 122.05 cubic inches=> (122.05 in3/rot)x(5,000 rot/min)x(ft3/(12 in)3 = 353.2 cubic feet per minute. A Toro electric leaf blower can provide 340 cfm. As 340 cfm

Why don't you look into a traditional air compressor with a small tank that can do 150PSI or so and then use a venturi tube to pull vacuum from the compressed air discharge. It works even better with water/fluid and a pump but IDK how you would do it on a car.

There's nothing like full testing of equipment, and that was nothing like a full test.

You are working with a way too low voltage. Try to get a high voltage Motor arround 48V for example. That will allow you to actually get reasonable power with s current draw that does not melt the cables. Atm you are only drawing 700W, for a supercharger/Turbo that is ridicously low

Yeah, more volts can mean less amps (less motor heat). Get the four smallest 130C Graphene 4S packs to make 44V / 12S. The motors come in different Kv's (RPM's per volt). Since you've removed the oiled center turbo cartridge, consider a ceramic shaft bearing. The oil didn't just lubricate, it also drew heat out of the bearings.

You're not understanding Brushless Motors to KV Rating and Voltage. When you're looking at just say a 7k brushless motor with a 4s Lipo you take the 7k rpm per volt of the brushless motor and multiply it by the 4s 14.4v lipo and you're already over 80k revolutions per minute. a 48v would absolutely destroy the compressor. Most Turbos spool up full boost around 120-140 revolutions per minute. Which is possible with brushless motors.

@@RC_Trailblazers Its possible to spec a much lower Kv motor and use higher volts to get the same RPMs. That way, you'd be using fewer amps to get the same power.

The problem with this setup.... I'm guessing that the volume of airflow is not going to be sufficient enough to get any noticeable boost on a car engine. As a car engine revs up it takes even more air to achieve the same boost level. That means boost will decrease as you rev the engine up. This will result in a very slight or nonexistent boost level at low rpm and no boost at high rpm or maybe even a restriction that causes the car to have a lower peak horsepower number than it would without the electric supercharger. Can you supercharge a car with an electric motor? Probably. Can you supercharge a car with this particular electric motor and setup? Probably not.

I gues you no longer need the oil feed as your using the motor bearings, shame the larger motors tend to have bigger shafts

Why not add some 3 to one gearing as typical turbos spool upto 150,000rpm. Be interesting to what turbo shaft speed you get

This would work to spool a bigger turbo or as you said to evac crank case pressure but idk if its getting enough voltage.... Use 2 car batterys and link them together for 24 volts bet she males some boost then

Plus you were talking about runs at the strip so the batterys only have to last for a run when ypur done put the maintainer on the system

This is why I think that garage tinkerers, doing stuff like this is good. If they can make something work for cheap then it forces manufacturers to drop the price. They charge what they can get away with. Look at all the aftermarket stuff available for car electronics, I can set up a car the same way as the dealer's top model for hundreds of dollars compared to the thousands that they include in the price, even now. But in comparison to a few years ago dealers have dropped the price of core units by about half. They just keep adding sensors and gadgets to keep the price up. Anyway, I agree that what he did wasn't probably going to work. But as another commentor posted, the Audi one draws about 7kw. But if you have an engine designed to produce 48v electric power, like the Honda IMA system in the CR-Z which makes 15kw, you've got power to spare. And you have to remember that the Audi E-charger is for a 4 liter V8. So it might even be over powered for a 1.5L. So a simpler design might work. I have to admit that for a driving situation like the Indy 500 it might be better to go with a traditional setup. But for a street car that doesn't require continuous max power for extended periods these make sense. The same way as hybrids do. And it might be the RC car/plane guys that can bring the experience and technical expertise to bear in making it work.

I want to see a dyno. On either a motorbike or a honda k20 engine. If it doesnt improve max bhp. Surely it can help bottom end and mid range. While remaining 100% safe.

In the past I bought a turbine, but the electric motor shaft does not get to take the spiral propeller.

The thing at the end of the video... Has to do with air mass, since centrifugal compressors depend on that to get the flow moving. Small radius means small volute volume, and not enough air mass contained within to impart much momentum upon. It's why the majority of those tiny scale hobby engines that try to use centrifugal methods of making boost will always come up short. (The inherent scaling of rotational speed to get similar compression at ever smaller volute sizes is not linear, and unfortunately you can't make it out of unobtanium.) Since when it comes down to basics it's just an air pump, I wonder how good something compact and electric powered could be made with a positive displacement system? Maybe a gear, screw, or rotary vane type compressor? That'd be fun to see on a go-kart than some turbo that doesn't see enough exhaust to do anything, or some "hair dryer" setup like this because of limitations of working with a small volute volume. For overall simplicity, I think this would be the thing to copy and try using with electric boost: en.wikipedia.org/wiki/Powerplus_supercharger Mechanically simple, and likely something that could be machined by a hobbyist.

RC cars and the RC hobby as a whole is for grown men..... Edit: If you can hold your finger on the motor then it's fine, if it is so hot that you can't keep your finger on it then it's too hot and needs extra cooling or an upgrade. That's the old test method if you don't have telemetry or an IR thermometer. I've had some 4x4 RC vehicles that would go over 60MPH on a 3S battery. Now I fly RC planes. I've spent thousands in this hobby. But no matter what you enjoy doing for fun, the old saying is true, if you wanna play then you gotta pay.

Yea seriously get a higher quality rc brushles motor esc combo because even if the power peaks are right the heat from the engine will surely burn those things up just get a bigger more robust setup doesn't mean you have to run them at their peak and use a heat shield on the motor and keep the esc inside the Car and the lipos in a lipo safe bag while your using them

Have been toying with a small dry shot of nitrous to help spool when the peddle is pressed completely down so I wouldn't need a switch. This though might be even better if it infact works as nitrous can get pricey for quick 25-50hp shots over time.

Great video great experiment ilove your videos thank you for doing these

drill a hole opposite the set screw hole 1/2 depth...at 60krpm the balance is extremely important. part of the reason its vibrating so much. gonna destroy the motor bearings.

This will definitely work as an evacuation pump, but it wont produce any usable boost (Positive pressure) on a car sized internal combustion engine, maybe a smaller motor (lawn mower sized). Drawing a vacuum and making pressure on a sealed unit (holding the pressure gauge to the blocked off compressor exhaust) is not the same as making positive pressure at free flow volume. Same concept as blowing air into a balloon (making positive pressure) and making boost by blowing into an intake with your mouth. In the simplest formula, it must be able to move the same volume of air as the engine normally uses WHILE at a greater than standard pressure. Thats why super chargers (technically turbos too) require substantial horsepower to operate and produce boost.

building pressure is one thing, but building pressure when the engine is pulling volume at the same time is quite another. most of those electric turbos will blow air but cant move enough air to keep up with the engine much less create boost or a positive pressure. Instead they cause a restriction and rob power.

Please please please search eBay for hx35w. Buy it and slap that motor on. That’ll get you some air volume at a low price. As for everyone asking how much boost can it make, just remember boost is a measurement of flow and restriction. That k03 would undoubtedly produce high numbers through a drinking stray but what can it do through intercooler and into a motor sucking as fast as you pump.

Wow that's impressive
