Many years ago I watched someone test a cheap electric supercharger that actually didn't make any boost on the dyno. I went searching for a real brushless setup on real go-fast parts but I guess nobody sold them yet. This is so cool to watch. So many possibilities for tuning for things like traction control, boost by gear or boost while off throttle similar to anti lag.

What that ESC just did was downright impressive

I'll be getting a max 4 because the test you ran...thanks again man...nice job just got to find good batteries for my losi 5ive-t 2.0

Awesome testing and results. Thanks for sharing your R&D with us. One thing I wanted to mention is that you might want to put a fan on your brushless motor. I'm not sure what kind of heat you're getting to with the motor, but try to keep it cool.

Man this content should be hitting further. Your doing something iv dreamt about doing forever, but never had the motivation to follow through, I absolutely cannot wait to get in on this tech whne ive some spare money and time and experiment. It kinda reminds me of when i build my first megasquirt, (before they got all closed source and bleh) exciting, pioneering times.

Wow Alex - this is super exciting! What a beast of a battery pack... the only issue I see is that hobbywing seem to discontinue items without notice so I hope the supply of those esc's is plentiful into the future. They certainly are good at bringing out decent and ever evolving products though. Awesome vid man and thank you for sharing your R&D journey.

What a contraption. I love it.

I was sad you gave up on VESC but you can't argue with results!

Thanks!

pretty neat test. 260A load is barely warming up for the Max4 and 2028. will be very interesting to see future development and application of this in 1:1 cars

Another great test!!! I took my P2 charger apart and was surprised to find the sealed ball bearings are only rated to 25,000rpm, I wonder how long they will last at that rpm.

Great stuff!!! Just purchased a 1997 Toyota Chaser with a 1jz-gte because my Mustang ecoboost motor blew up. Would be cool to stuff one of your setups in either car.🔥🔥

Good Work !

Always good when the smoke stays inside! 😎

Love to see these vids. Wondering if you ever gonna setup a diy type list of the best off the shelf parts, or a kit to do something like this for a car. Electric superchargers are a sorely under rated platform. Would love to try a diy setup for a rotary engine. Don't need a huge boost but anything to help low end torque and low to mid power would be great.

I was mentioning your videos to a friend of mine that builds a lot of things with electric motors and mentioned that your belt was getting hot and he asked if your belt had a groove down the center of the teeth. He said a groove down the teeth would help keep the belt cool because it allows the air being compressed between the belt and the pulley to escape.

@AlexLTDLX

Жыл бұрын

Your friend is on point. Jon Bond - the guy who rebuilds superchargers is Jon Bond performance - told me that was a trick they used on the Powerdyne internal belt driven blowers to make the internal belts last longer. I might do that at some point down the road, but really the point of this is to make an affordable and easy to duplicate unit.

Do you place the restrictor on the inlet or outlet side?

Still hoping to get one of these setup on my 6.1 Hemi...This is effing phenomenal... I am an RC guy so this is right up my alley in two hobbies. Gonna need a cooler for the motor and ESC, my goals are inline with typical bolt on stuff, 4-5 psi at peak rpm/load, maybe 550whp. Anything else is pushing efficiency of the whole shebang and risking bottom end. I am curious though about running twins. The packaging possibilities are so good that it is less absurd than typical twin anything. Wonder about differential sized twins too. The Toyota/Lexus UZ world would eat this thing up too if we ever get a serious tuning platform for our old trucks. They really only want about 4-5 psi anyways, so if you take away the parasitic loss from a normal blower, maintaining 4psi at any RPM would be absolutely incredible. In fact I suspect the 2 UZ wouldn't want it below 3300 rpm or so, might start killing rods.... ... I may order an ESC and a 2028, basic mounts to start playing with them, in the event they disappear, plus cheap ordering requires months of wait on shipping.

Shiiiit it'll be awesome if this turns into a product, ill definitely have myself one of these.

how about one for daily driving. Im using a honda 3.5 v6 what do we need?

Now I wanna see a heart rate monitor along with all the rest of the data. Help everyone better appreciate the excitement and stress of running these tests.

If there was a weak link, I think you would have found it with this. Good one!

Ok thats all cool, but will this motor esc combo be good on my Limitless for speed runs🤷

That small green digital voltage display is probably not very accurate if I'm not mistaken, as it looks like one that I purchased from amazon (potentially) and when plugged into my power supply, the reading was almost 0.5v off. Not sure if that matters but I was going to use one with a momentary switch on top of my battery box for a quick voltage check. If you have a recommendation on a more accurate identical 3 digit display, I'm all ears. I'll mail you one of them just for a comparison. They were cheap.

I think I missed something. Was the Castle ESC not enough for this setup?

I am curious about the amp meter (green) vs. the Hobbywing data logger amperage, so is that showing us battery amps and Hobbywing is showing phase amps? In general whats the rough cost of MGM motor/controller setup vs Hobbywing motor/controller setup, and do you like the software better than Vesc, I personally like Vesc it allows me to change any parameter, which can be a pro and a con. Slap the LTM on there and do a pull with the Hobbywing just to blow some hot numbers around. A little bit of ramp-up time might cure your contactor issue, keep the belt cooler, and it will help with the current spike and you will never notice it in the car. (spool times exhaust vs. pixes) Great Test! by the way I dissect the video frame by frame for the raw data, like you said R&D is a fire hazard. Mine is 23s Lifepo4 84v.

Put caps across the economizer when using this, should buffer the current spike

Hi Alex I wonder if there's another impeller and housing option for a smaller horsepower, say 300 hp, enigne, thanks.

@AlexLTDLX

Жыл бұрын

This would work for 300 hp. The reason why I'm sticking with this is that it's the easiest/cheapest/most commonly available. The issue isn't so much hp, as much as the boost pressure require for that hp. This blower will support 300 hp at anything up to 11 psi. The closer to 11 psi you get, the closer you get to surge. So, in other words, if the base engine is 200hp, you'd need about 7.5 psi to hit 300hp - that would be just fine for this compressor. However, if you have an engine with a base hp of 150, you'd need 14.7 psi of boost to hit 300 hp - this compressor would be in surge at that point. Sizing a compressor for electric boost is a different mindset (though using the compressor map is still required) than a conventional turbo.

That is awesome! Can't wait for the poor man's 200hp version :)

What lipo battery's are you talking about

@AlexLTDLX

5 ай бұрын

These aren't LiPos - they're LTO cells. Specifically Lishen 18ah LTO cells. I have yet to find a LiPo that can compete with them, output-wise.

So about that belt.... how many watts of power is going into heat? Timing belts are probably 97-98% efficient at best. My math says you're probably pushing 1/2 hp (~300-400w) of heat it that tiny thing. If you wanted it to make it's life be longer, maybe multiple parallel belts would help or a different belt. I wonder if gears from a 5th scale RC car or a 700 series helicopter might work. When I did supermileage, we bought saver Gates belts that had carbon fiber tensile strands and the teeth were Teflon coated... claimed to about 99% efficient. The might be a bit large to package it in this situation and I think the smallest sprocket would be ~11 or 12 teeth with a 8mm pitch (~2 - 2.25" in diameter). The larger diameter would provide less tensile load on the belt, but the feet-per-minute would be insane. I'm curious what the max speed on a belt like that would be.

@AlexLTDLX

Жыл бұрын

I'm trying not to complicate the drive at all. This timing belt pulley is what comes with the blower so if we can utilize that effectively then that simplifies things dramatically.

I’m thinking about minutes, not seconds and a land speed record with Ardema Braun . I’m certain it’s crazy but possible. You ever see Greg Quirin and his videos of those guys. Homemade engines and land speed, probably no class for them…. Yet

Almost 3 times less current then the other setup, with only 4krpm less, i would say that is a huge win. And that ESC did'nt even get hot. 38ºC is neglegible

This is all geeky a fun gadgetry making spinning whizzing noises with big amp numbers and shiny c&c metal parts, and if it could produce double of what you’re saying it is now I could see it being worth talking about. But 600hp when that’s achievable n/a with junkyard LS’s and cams and intakes? And 1400-1500hp with LS 427s and torqustorm superchargers. I don’t get it. Is this thing ever going to rev the impeller up to the compressor map and make any boost worth measuring?(like above 10psi) 24krpm is yard leaf blower speeds. Must be a Ford thing. Little hp numbers get all exciting. …but 1200, that would be something. 600?

I can build it and install it. But I need a parts list. I cant paint I cant trace but I can beauitifully install.

So by my calculations, based on simple current and voltage, the motor was drawing about 82 kW of power, or 109 horsepower. That is really impressive for the motor's size. Wow.

Golf Cart battery? Dude you're on a completely different dimension if you think any standard 36V/48V golf cart battery (or the individual 6V/12V batteries in series it is composed of) has a chance at powering this setup. There really isn't ANYTHING out there that compares to LTO cells and the Lishens are considered to be some of the best if not the best. Despite being less than half the size of the 40Ah YinLongs they perform similarly.....so paralleling these cells to almost match d Ah capacity of other LTO cells shows these things are anywhere from twice as powerful to about 25% more powerful... The only other LTO cells I can think of that MIGHT outperform these Lishens is Toshiba SCiBs...I haven't found a real datasheet yet but Sriko Batteries claims the 10Ah cells are rated for 75C peak discharge. So 750A from a 10Ah cell....or a 6S "12V" battery would be able to burst 10kw of power while still maintaining an acceptable "12V" voltage. Supercapacitors with extremely low ESR can burst similar (and sometimes more) current but you have to remember that even 3000F Maxwell Boost Caps have the watt hour capacity of like a AA alkaline battery....they can dump it almost instantaneously but this is an application that requires more than just occasional bursts measured in

There is a much better option. You don't need to draw all that line current. Use an ebike controller that can handle the erpm and current required. Run it between 36v-126V. I'm sure you know the math.
