DIY Electric Turbo: Sledgehammer Assembly

[@WXSTANG]

ZERO boost lag! This is awesome. You can literally spool it up when you want and have full boost before even launching it. Better yet, control the boost to create traction control.

[@MrChris7582]

when its ready to be sold as a dyi kit let me know. I am jealous of your machining skills I have none. keep up the good work. I was expecting the motor mount to have bearings for some reason. lol.

[@AlexLTDLX]

Thanks! Keep an eye on electrifiedboost.com - if I reach a point where I'm comfortable selling parts (doubt I'd ever do a complete kit - everyone's requirements are very different, and there's a liability aspect to consider), it'll happen there. Here's how I acquired my machining skills: I married extremely poorly, then became a single dad. When my daughter was too young to be left alone at night, I starting spending hours in the garage. First porting, then over the years machining. I can't recommend that technique though - the lawyers are far more expensive than a shop with good machine tools...

[@MrChris7582]

@@AlexLTDLX lol I had the single dad part down but I spent hours learning how to do computer programming at night instead. I am however a "back yard" mechanic and have assembled an engine from bare bones. I can get the turbo and rc plane motor and batteries/controller on my own. I just have no idea how to make those machined parts. the closest thing I ever got to machining anything was porting and polishing heads with a dremel and getting a harbor freight hone tool to put a new set of pistons in. I can assemble things like the best of them. lol. even have done some mild welding. tack welds and arc welds and some mig welding as well. mostly just to make custom exhaust and a light amount of fabrication work. I actually do want to learn to do some machine work at some point. but its just a hobby for me so who knows if I will learn everything I want to learn or not. I was just saying you already got one working. but I hear of all these newer cars coming with some electric turbos stock. so its only a matter of time before theres an affordable one. the demand is there. I actually have a procharger on my current set up. being able to take away the pulley would be nice. and the torqueamp ones dont make enough boost and restrict air for larger displacement and I got a v8 lt1 gen 2 and a 5.3 liter ls based truck engine I am just starting to work on now.

[@AlexLTDLX]

I think you're probably right - we'll start seeing more and more of these in OEM applications. There's a much greater return in using electrical energy to power a turbo than to put it directly to the wheels. If nothing else, to help meet CAFE standards.

[@nate0031]

​@@AlexLTDLX On the, "much greater return in using electrical energy to power a turbo than to put it directly to the wheels." I'd say that's pretty backwards. You're using a motor to drive a 60-80% efficient compressor, then just dumping that extra 20-40% of energy to atmosphere as heat. That's not even taking into account the motors efficiency (Probably in the 90% range), and the typical car alternator efficiency of ~60-70%. So all in all, this is a far less efficient way of driving a supercharger, and far, far less efficient thing to do with the electricity than just drive the wheels, as you're skipping a whole round of efficiency losses by just coupling the electric motor to the wheels.

Intake temps and EGT's are such a pain in the ass and there is no way of getting around them with the typical turbo set up. Ive looked into supercharging and everyone says it's not for diesels due to parasitic loss and what not. And really the only thing that comes up is Detroits 2stroke engine with blower style setups which are meh at best As soon as I heard about electric turbos I instantly knew how much of a game changer those could be and also knew the limitations.

[@JViello]

Good job my brother. I sold my turbo kit design and manufacturing business back in 06-07...Got married, started family opened a new business etc etc. I got into hardcore RC around that time and first time I saw the power the BLDC motors were capable of, this idea came to mind. I have been waiting for someone to catch on and do it! When audi talked about their electric turbo I waited and was like "Maybe....mayyyybe? NO! So close!" lol In the progress of designing in my head I ended up at a supercharger head as well. LOL It just makes sense. Best of luck, I hope it works out. Just a thought for quick charge ups, discharges etc. Go supercaps instead of lipo or whatever. Yea, more expensive but the charge/discharge rate can't be beat. There is actually a supercapacitor "battery" made for the car audio industry it would be a nice easy "premade" unit if you don't feel like going through the hassle.

[@AlexLTDLX]

Thanks. It already did work out: kzbin.info/www/bejne/d4CvZISvmN-nabs This is our attempt for big power. Supercaps (I have a giant supercap setup that I tested for other things - it's designed to start semis and trains - I did a self discharge video on it) would actually be a poor choice because the voltage discharge curve is linear and the power density is really low. I'm now using Lishen 18ah LTO cells - also used in high power car audio - those things are beasts. I tried stick welding (also a video) with them and couldn't keep the amperage low enough. Would be great for stick welding 1/2" steel with 5/32" electrodes, though!

@@AlexLTDLX BTW, have you done a “boost school-math class” video on how to determine how much boost you can get out of a charger at x rpm?

[@ethayer1]

Hey, look into the Aisin AMR500. It’s a small supercharger, costing usually $200 and readily available. It can support up to 400hp(supposedly) but is great for smaller motors. How big is your motor? Believe it or not, the engine doesn’t dictate the max power of a turbo or supercharger, it’s all in how much it can flow. You should be able to calculate flow rates, if so you can make a “guesstimate” of roughly 10hp per lb of air per hour. So if a turbo/SC can support 50lb/hr, it CAN make 500hp(before efficiency losses)

[@dirtfreak661]

Awesome project! What I don't understand: don't the rpm limits of a radial impeller itself and the motor fit together or does the motor run out of torque at these high speeds? I was wondering if I could recycle old turbochargers by bolting a kW motor to the shaft. I have some leftover stuff but I'd have to find a solution for the hydraulic bearing, like a small oil circuit driven by an electric pump since there's no issue with heat on the shaft

[@AlexLTDLX]

Basically, right now it's a balance between available motors, torque and impeller rpm. Many people have suggested to gear up a lower rpm motor. The biggest issue is size - a 30kW, 10,000 rpm motor is a lot bigger than a 30kW, 50,000 rpm motor. Simply because the slower motor makes 5 times the torque. And the main reasons why I went with a supercharger instead of a turbo is the exducer and inducer sizes are more favorable for this kind of thing and the bearing issues are already sorted out. I use Isoflex nbu-15 grease from Kluber to lube the bearings. The same lube some positive displacement blowers use in their "permanently lubed" rotor bearings. It is expensive though - a 50ml tube is around $50.

Would you not get better performance with the gears or is there a factor I'm not thinking of

[@AlexLTDLX]

That's a good question. The problem with using a lower RPM/higher torque motor is primarily weight and size go up. Like by a lot. This is about the most compact balance of RPM/power that's available to the masses. I'm sure eventually that'll change, but for now it is what it is. The other issue is very high speed gear/belt drives bring in some small losses but also present additional engineering challenges - like heat build up and lubrication. Look at it in terms of watts (heat) - 5% losses on a 40hp drive is about 1,500 watts of heat you need to get rid of.

The challenge is motor availability vs rpm. Beyond that, another issue is long cables and high motor rpm, but I think I have that issue solved.

It would be a really fun and interesting experiment to power the electric motor on this turbo by a generator or alternator being spun by a hot side of a turbo! It would eliminate the heat transfer that normally happens from hot side to cold side. And you could also store and buffer the power with batteries and capacitors if you wanted to. I wonder if an alternator would work for that if you geared it right.

With a button to increase the voltage to the turbine for additional power when overtaking.

One of the German makers was looking into scavenging every btu of heat going down the pipe- heat is energy- and turning it into amps via turbines.. which was going to 'help' the ICE engine by putting torque directly to the crank.

"Fantastic Beasts and Where to Find Them"? outstanding! I'm looking at it as a hobbyist, and ex jewelers machinist, SME certed back when. yeah that motor in a go-cart would probably run 8 second QM's, for giggles. that "flex coupler", perfectly simple, hopefully the driven bolt wont shear on ya.

[@AlexLTDLX]

The 6mm bolt has a tightening torque spec of 14 ft-lbs. The LMT motor, at full tilt, is rated at 40kW and 50,000 rpm. 40kW is 53 hp. Hp is a function of torque and rpm. So if it hits 53hp at 50,000 rpm, that's only 5.4 ft-lbs of torque. If it hits 53 hp at 25,000 rpm, that' still only 11 ft-lbs. In the first version (20kW peak, 14kW continuous), the 6mm bolt had no issues. The math says it should be fine here too - in fact, I consider it a mechanical fuse - but if it does shear, I'll just move up to an 8mm bolt with the head milled down to a 10mm hex. But dynamic real world loads might cause issues - only one way to find out!

[@silverwolf4095]

@@AlexLTDLX BOV should protect the 6mm from throttle closing quickly. The motor should be capable of serious power from 10k. Have some experience with 40mm NEU motors, in Y wind they can do continuous power from 10k. Max efficiency at 35k. Bearings good to 60k.

Why remove the vortech gearing? Drivetrain loss? Seems like a perfect setup to use multiple motors, pulleys to fine tune the compressor rpm

[@AlexLTDLX]

Because power is torque x rpm. And the more torque a motor produces for a given power, the larger the motor has to be. A similar power motor to the one I'm using here that spins at only 8,000 rpm would easily weigh at least 50-80 lbs and be a lot bigger.

[@butziporsche8646]

My hobby is model engineering and the British have a saying about American model engineering. They like a draw-filed finish but Americans tend to polish our stuff. The expression is derogatory: "Highly Polished and Deeply Scratched" because we polish it over the scratches rather than filing/sanding out the scratches prior to polishing.

[@AlexLTDLX]

That's pretty much what I did. It was quick and easy.

[@njmxjunkie3128]

How would someone tune their engine for this? Although I’d assume you can figure a way to use a pressure sensor and some electrical components to keep your boost at a specific pressure no patter the rpm. You’d have to have it automatically adjust the motor speed accordingly with either throttle position or relative to intake pressure/boost

In my case it's on full speed once the throttle is over 80% and the engine is over 3,000 rpm; since the car makes 500 hp N/A, I'm going for max power. But you could easily stage it. I'm working on a "universal" controller based on a differential MAP sensor.

I have a question why do you remove the gear train is it too much stain on the motor for startup and if so can't you set the motor to sit in a idle or is it still to much strain I've always been very interested in electric superchargers

[@AlexLTDLX]

It's a balance of motor size/rpm/torque. You could go with a lower RPM motor (that would be easier to control), but the motor would require more torque, and more torque = more size and weight.

You just snagged a `scriber... I used to be madly passionate about cars some time ago, but my main focus was machining and machines... I watch jafro to keep my automotive passions up, but you just hit the spot... Ang. con. ball bearings in a turbo... Most interesting... Not sure as to how brilliant of an idea that really is, as any gunk will mess those up real quick and in a hurry, and engine oil is definitely not clean enough for such lubrication even after 10 hours of engine work, but hey, fuck do i know, i just saw this shiny block for the first time, maybe the oil is just cooling the thing and bearings are sealed and grease lubed with an ultra high speed spindle bearing grease... I didnt even pay attention to the number of ports on the thing to even check if it was coolant cooled or oil cooled... I was just pleased to see both of my interests overlap... And btw, i love the ``you`ll have to deal with it`` attitude... All the best and kind regards! Steuss

[@AlexLTDLX]

Thanks. I used Kluber's Isoflex 15 grease in the bearings and they have so far held up fine for the last year without any maintenance. Since this thing doesn't spin all the time, I think it should last for quite a while.

[@camillosteuss]

@@AlexLTDLX Aaah, so bearings are not oil lubed? Kluber makes some fine stuff... I use Kluber LDS Special A, as that is what my milling machine uses in her spindle bearings... Of course i don`t waste it on random bearings and every bearing, but when there is a bearing and an application where i want to rely on quality rather than service every year, i use that grease... It`s designed to run loaded mill spindle ultra high precision bearings for 5 years between changes, so you know it`s some good shit... I will definitely remember this video for future reference... I am a car nut afterall... This type of modification will likely find its way into a few of my cars... I have a few of my own lunatic ideas and designs, but this is much more tame and more easily doable when compared to a custom special engine with custom induction, exhaust, ``valving``, lubrication and ancillary systems... Not to speak of an exhaust cooling steam system with a turbine and condensers, all merely there to act as another induction system that partially feeds into exhaust to make a pressure delta via velocity differential as to put negative pressure on the exhaust manifold, while also having a single thin tube for secondary exhaust combustion - metered so it doesn`t mess with O2 sensors... And 4 small lines that would feed constant warm air(around 75C) to brake rotors, which would keep them closer to optimal operational temp, while also cooling them during harder use, as the turbine would likely be spooled by hard engine use(hot exhaust), and would continue to blast air through its metered lines for a minute or two just on heat inertia of the whole system... Oh, have i mentioned that the car would be converted to 4wheel drive, but all 4 wheels would be ran by independent hydraulic motors and would have 4 wheel steering and hydraulic suspension? Yeah, that is my kind of madness, so you see why i called your sledgehammer more tame... But that kind of madness has to wait... That shit will snort lines of my cash like a rockstar, and i need a special car to do it, something worthy of such a massive project and undertaking... Aaand i need to build a new shop to fit all my stuff... All the best and warm regards! Steuss

[@bleeb1347]

I have a REALLY stupid question, but forgive me because I’m an engineer….but….why did you remove the gearing? Couldn’t you have pushed far more rpm (and as a result, higher boost) at the impeller with the gearing?

[@AlexLTDLX]

That's a good question. And there's a good reason - high speed, lower torque motors are generally lighter, cheaper and smaller. And horsepower (like watts) is an actual measure of work. You could have a 50,000 rpm motor that fits in the palm of your hand and makes 53 hp - which happens to describe the motor I'm using. A low speed, 53 hp electric motor that only spins to 10,000 rpm would weigh at least 80 lbs and be at least 5 times bigger - yet both are capable of doing the same work. Actually, the direct drive unit (i.e. 50,000 rpm) is more efficient because there are no gearing losses and the magnet to stator gap is smaller. Now if you're wondering why I don't run gearing on the motor I've got to get more rpm, it's because as you go up in rpm, you lose torque - and we're already power limited.

Why did you choose a supercharger as your base for this? I was thinking of making something like this but I was planning to use a turbo with a blown exhaust housing. Just what you had on hand? Or is there something I'm not thinking...?

[@AlexLTDLX]

Good question - turbos generally require higher impeller speeds than centrifugal superchargers. Given the hp level I was looking for (editing the second dyno video right now - and this thing is definitely capable of 800 flywheel hp on a good weather day), and the available brushless motors/ESCs, this seemed like a logical choice. If you're looking for less power, there are smaller brushless motors that can turn 75,000 rpm; but definitely check out the P2 versions on my channel - they make make less power, but are a lot cheaper and are more "tunable" given the belt drive and available pulley ratios. You could optimize those for a particular engine much easier.

When someone says that polishing is the quickest way to get a decent finish on something... It means they don't have a media blaster.
