Dude…..I’m impressed. That don’t happen often. I just can’t get over how the little motor(electric) makes so much power.
I'm still shocked (no pun intended) at how much power these little motors can put out - if you haven't seen it, check out our dragstrip test where I overlay the power consumption during the pass: ua-cam.com/video/nlTVHkfSQXM/v-deo.html - this is with a different motor, though.
You’re smart as fuck and i believe in what you’re doing!
Thanks for the kind words. If you knew some of the life choices I've made, you might change you mind on the first compliment - but I'll take it. Thanks! If you haven't seen it, we drag tested this thing: ua-cam.com/video/AOL3Qyczt3Y/v-deo.html
Wow Alex you are really digging deep in getting the most out of it, I didn't know there was so much more to increase the efficiency. Can't wait for the next vid!
I have been following this series since the beginning, and have LOVED it. I am really surprised you aren't getting more views on these!
Thanks. And on the views thing, I think (hope) views pickup, particularly once we go to the dyno. I want to try to take care of as much "low hanging fruit" as possible before that.
I've always been intrigued by the idea of an electric supercharger. Just don't have the know-how to create something properly myself. Enjoying watching your progress.
I totally agree with you and i am really curious if my 535d BMW biturbo could be equipped with such a huge Electric turbo
You share a lot of knowledge, and it makes sense. Thank you.
Thanks for watching!
And WTF, this video deserves at least 1 million views by now I don’t fucking understand what’s going on here. You are the only person to Develop a real deal electric turbocharger. By the way what size engine Are you running?
Lol - I agree. It's 365ci Dart block SBF with ported Twisted Wedge heads (185cc, 292cfm intake flow on a real flow bench - in fact, the heads have been flowed on two different benches).
Actually felt like I learned something
Alex, how many watts would you feel comfortable putting into your current set up? Even with the 16 full charged cells, you were at ~13,000 Kw right? Since you’re literally the first person ever to accomplish a high powered electric turbo, and you have developed a feel for your set up by thisPoint, how much Electrical power would it handle? Do you think the Vortx could handle a 40 KW motor? Also have you considered using both conventional and electric forced induction simultaneously? I’d be kind of cool to have a Compound set up with the electric feeding a secondary conventional medium turbo. 20 KW and a medium large turbo seems two might be a great set up. One more question. Ideally what would be your target voltage and amperage? 63V and 350A= 22kw
Alot of questions... the motor itself is rated to draw 53 volts at 283 amps peak for 10 seconds - 15,000 watts. It's only rated for 7,500 watts continuous. So we're pretty close to the max burst throughout the pull. That's measured at the ESC input though. I would assume that's how it's intended to be measured because on the motor side you'd have to start looking at some sort of three phase average (.707 (rms) etc). I do think the ESC is the weakest link simply because we blew the lesser one. But this one's rated for more current and a lot more voltage, so maybe we're good. The motor's pretty much taking everything's it's getting; so there are still a few more electrical tweaks we can do and then we have to start looking at compressor side improvements - wherever we end up will be it for this setup - probably around 53-54 volts at 290-300 amps. The Vortech could certainly handle a 40 kW motor - the weak link is the hex drive, and that still has a factor of 5 (at least) safety margin with this current setup. I think I'll stick with just electric boost on this because it's never been done on a significant scale and it can be done, as we've proved I think.
This needs more views!
Couldn't agree more :)
I'm in to car audio and DIY lithium banks are all the rage but I bet a company like Limitless Lithium could put together a pretty bitchin power source for these things if they're not already
Nice! I love the whole electric boost saga! Also, if you want a new esc you can get some of the flier brand. Those wont blow up!
Lol - that's what I'm running: ua-cam.com/video/XL8JAvVERHA/v-deo.html Thanks!
Lol 😂😂😂 your electric turbo is my electric centrifugal supercharger
lol
I cant wait to ride this badboy
What about mapping the TPS voltage to the ESC's duty cycle? Then you'll have the ability to eliminate the full on/off switch and instead spool it up based on throttle position.
As long as the compressor isn't going into surge, there's no reason to ramp it in. Unless you can think of a time on the street (or road course or drag strip) when 500 hp isn't enough but 700 is too much (or any similar permutation of torque/rpm).
Well that sounded like the way
What if you used a geared headunit and a PMAC motor they use for electric motorcycle conversions like a throttle on your steering wheel instant boost when you want it
You could, but I don't think it's necessary. If we were dealing with a lot more boost, then it would be worth considering.
will you be selling something like this one someday? looks cool!
At this point, the magic 8 ball says, "it's possible."
@@AlexLTDLX coooooool
Have you considered a bypass valve to overcome the 1psi restriction? TorqAmp uses a mechanical valve to overcome this. If you bring this to market with at least 6psi I'll be looking to purchase !!!
I don't know why you'd need that - I suppose you could fab something up, but 330+ hp to the wheels pulling through the blower is more than enough for street driving. Before we bring it to market, let's see how much HP we can make first!
I think voltage drop is hurting you in multiple ways. I think I saw 11v during boost. I would look into that a little more.
Are you looking at the air fuel gauge (the blue gauge in the center at the top)? Battery voltage in the car is pretty solid at 13.8 and the electrical system for the electric turbo is completely separate and doesn't go below 52 volts.
I'm really loving going through all these videos. Thank you so much for sharing this all with us. My TVS blower takes so much horsepower just to spin up, I can imagine I could have so much more usable power at a much lower boost pressure if it is not driven from the crank shaft. You may change the world with this as a foundation.
I just have this one request. It's your hands... I was watching them as you were talking for a very long time and I'd really like to see more cuts, scrapes, and maybe even a little blood. Nothing serious, you know dont lose a finger on my account. I'm just saying it would be a lot more entertaining if there were more scabs and scars or maybe some burns or blisters.
Just a suggestion.
I'm so glad I found your project and appreciate the natural tone in the way you present this information.
Fruity
Would ultra caps improve your setup? When compaired to your capacitors?
Not really - the start current is plenty strong and super caps would drain very quickly. I have a car-battery sized super cap sitting on my other desk. I did a video measuring it's self-discharge some time back. They have a very low internal resistance (massive current spikes), but a very low overall capacity - I measured something around 1 amp/hr at a 1.5 amp drain down to practically no voltage. Thanks for watching and taking the time to offer up suggestions!
@@AlexLTDLX i dont know much about ultra caps, i just figured it was the newest cap and the price reflects.
Concept proven. Proove more. Keep doing good work.
Loving this. :)
Me too! Lol. Thanks.
I'm definitely in the market for one.. just waiting for someone to make one that can at least hold 5lbs. Or just me more low end power.
This can easily make 5 psi or more, just not on the current 6.0L V8 that's in the car. On a miata engine (for example), it'll likely go into surge around 8-9 psi. On the other hand, you can easily use this drive motor on a smaller impeller and support the same power level that we've already seen on the dyno - ~600 flywheel hp. On a typical 180hp miata engine, with the right impeller but same drive motor, you'd see roughly 28 psi before running out of steam. Sizing the compressor is critical to success.
Supercapacitors shoudl provide the extra power that you need...
Now that we've doubled up the battery packs we have enough power to destroy the (expensive) ESC and melt down the motor. I do have super capacitors in the car (this monster: ua-cam.com/video/_HHxkMVnHQY/v-deo.html), but they help start it. To get enough supercapacitors to handle the voltage would cost over a grand (needs to be good for at least 70 volts). Believe it or not, you're not the first to suggest supercaps, but in my testing even though they have a tremendous burst current capability, voltage dropoff is almost linear, and even my car-battery sized supercapacitor has less than 2 amp hours of capacity - both features that aren't good for this project. After much exploration, Lipos are the way to go. I do have 4 100 amp hour LifePo4 cells on the way for playing around with though. But those will likely replace the car battery (and maybe even the supercap - 100 amp hours is a lot of capacity; even though I run the radiator fan and water pump (both electric) between rounds at the track to cool the car down).
Those impellers are not cheap. Especially if you have to go billet. Hope someone watching can hook you up.
What is your opinion on the torq amp? It provides positive boost of 5 to 6 psi till about 5000 rpm and then the engine is sucking in more air above 5000 rpm than the torq amp can move. This is on a 3.5 V6. It does provide about a 30% power bump from 1000 to 5000 rpm, but 30% is peak and it drops off the higher you go. Do you think there could be enough improvements to get an electric turbo to hold positive boost of 6 to 8 psi all the way to around 7200?
The torqamp is much smaller and less powerful. That only has 5kW and supports on about 200 fwhp. Our little project here peaks over 22 kW (over 15 kW sustained) and supports 600 fwhp. And I'm pretty sure we'll eventually see 700+. I think at this power level, 7 psi max is reasonable. But you have to carefully match the compressor to the motor.
I had a feeling you were experiencing internal leakage. The amount of power you’re putting in and the PSI you’re getting out didn’t seem right. I just heard your SC impeller issue. Something to think about, if you can achieve a 5 µm or less gap, Air leakage almost drops to zero.
That's another thing to consider. I did have to play with axial preload, because at one point I had close to .009" play. This time when I put it together there wasn't any. I'll have to see if it's loosened up any. If I do go the Si impeller route and I have to machine my volute, maybe I'll play the clearance at least in the throat a little tighter. Currently there's close to .011" gap between the impeller blades and the volute. That's apparently normal for these.
Do you ever plan on selling these? I want the Torque Amp kit but it's not worth it for $2500. Not enough PSI
Not at this time, but who knows. It is quite dangerous. And it would probably cost more than the Torque Amp (the batteries, ESC and motor alone cost almost $1,500 in this setup - that doesn't include the blower, control stuff or cabling/connectors/boxes). I think you'd be lucky to see a $3,500-$4,000 price point on this thing. To be completely honest, I could spend the same amount on a turbo kit and run 8's. But hey, it's a start. And it does have it's advantages.
1 more idea ... look into "Laminar Flow"
I'm familiar with laminar flow, but how are you thinking it applies here?
Whats the name of turbocharger?
It started out as a Vortech supercharger - but there's been a lot of work done to it. Here's the playlist: ua-cam.com/play/PLhacdpER4T0vzo531cmfi_7fJWd-7DSSt.html
You forgot the most important update, how is the toilet working? )
Lol... So far so good!
Hey brother what about supercapacitors?
Good idea, but not really feasible here once you run the numbers. Better off with more/bigger batteries. It's cheaper, too.
2 caps and some grease, for the whole video almost?
