This is like a way beefed up system that I was thinking about as an addition to a turbocharged car! My idea was to add a small motor that is capable of helping the engine in low RPM range only as a filler for a turbo lag with a capability to run continuosly for just a few seconds to flatten torque curve.
There is zero economy since you add several hundred kilos in the car and lead more rotating mass all the time with your engine. + you have to buy all this stuff so the economy is completly bullshit. If you want economy,reduce the mass,reduce the displacement ,increase the efficiency.
Weight is my point. Say the car makes 400hp and weighs 4000lbs. If you add 250lbs of weight to the car, you will need to gain 25hp to cancel out the added weight to remain at a 10lb:1hp ratio. To gain any realistic performance, you would want 50hp for that 250lbs, maybe even more depending on the cost of the system.
Sounds like a loaf of bullshit, big clue is that they included stop/start which has been proven to be a marketing and emissions scam popularized by big auto manufacturers. The added weight of the battery's and writing and the motor huge cogged pulley you have to bolt onto the crankshaft, not to mention how it's gonna beat the shit outta your main bearings.
Paul Wilson that's what I'm thinking I love my old chevy truck if I can get that kind of gas mileage and a boost in acceleration it would be a win win situation, and the extra weight isn't much more than a toolbox
cartmanrlsusall yea a turbo you get 50-120% increases in Port levels with a 20% parasitic loss for a final power increase of 30-100% . Where as this might add 20% but adds more than 2x the weight that it adds in power plus parasitic losses and beats the absolute shit out of your main bearings.
@@michaelherold181 maybe, but these engines weren't designed with such a large load on the front pulley in mind I wonder if a torque converter replacement that can do the same is at all practical

That's awesome! Wish people would do more swaps with older cars that used to get 8 miles per gallon, with engines that would allow it to reach "affordable" standards like 20 mpg
I was just thinking about a system like this the other day. But I would love to see this replace both the alternator and the starter first. That would allow for a nice weight reduction (vs this system as is, obviously not over stock). At that point, I would be all over a kit like this.

If you would like to verify that you can check out my channel. But this is not a conventional vehicle. Many electric motors can be used to generate power which would render an alternator unnecessary. If this system can be used for regenerative braking, it can likely charge a battery in much the same way an alternator can. Furthermore, this is a big ole electric motor strapped to a small block. A starter motor is just a little electric motor strapped to a small block. There's no need for two of them. Most conventional (by which I mean non plug-in) hybrids don't have a starter, but rather use the electric motor already there to do the same job. Check out the link Fullboost posted just above, he actually says you don't need either of these things with the e charger.
as long as it's built into the input of the transmission, because if it is on the output or the driveshaft it would be useless. You wouldn't get the torque multiplication.
Maximus Psychosis not quite, the Prius has two electric motors and is a series/parallel system. I'm thinking along the lines of what GM did with their hybrid truck and Honda with their first Hybrid Accord with the V6 ... a parallel system. Basically the electric motor is between the engine/transmission and assists on takeoff where the torque from the electric motor would be greatly beneficial.
I'm actually surprised it hasn't been done sooner. True hot rodders like extra power and efficiency any way the can get it. Battery powered superchargers as well. Turn on and off like a nitrous shot from a smaller battery, or run constantly with regen brakes and a big battery pack.
wonderful inovation. I was very impressed. Yes its bulky and alittle big, but its a first step in looking out side of the box. I think this idea will lead to bigger and better ideas. GOOD JOB
I would really prefer one that bolts to the pressure plate of the clutch and can work as all electric with engine charging mode, electric take off, hill decent charging, electric motor starting, engine only mode ect
I was trying to get funding to make this for semi-trucks 3 years ago. Couldn't get the money, but I knew somebody else would.

JoshTheLewi so was I but there is a legit company making them I can't remember who they are but they ran a 48v system for the supercharger, Borg Warner is making a electric turbo to assist a regular turbo it's called the ebooster.
Im sure the car company love it when a guy builds something like this especially when the manufacturers are trying to convince the public that they build the most technologically advanced and efficient cars. I hope this guy isnt found dead because of his cool ideas.
Actually old news. This has been around in the UK for awhile. Big rigs or lorries as they call them have had electric assist for years. Helps pull heavy loads uphill while reducing fuel consumption.
Jr alexander sounds good did you fully rebuild your top end and also do you use P.T.F.E eg..slick 50 to line up the sleeves coz that’s pretty impressive
They may have a slightly better market for a larger truck. I think a lot of truck owners who use them for work (small business) would probably SERIOUSLY consider it if it can save / make them money over the long haul in gas savings. Especially if it helps their towing capabilities.
I think a lot of people are missing the point... this isn't an electric super charger or a "power adder". it is a universal system that reduces load on the engine. the effect is more of the engines power being used to turn the wheels, not being waster on drag. its a proof of concept and I think its going in the right direction. How about the guy that has a work truck (LS V8...) and doesn't want to keep making the fuel payments (cash and environmentally), he can add this system to greatly reduce carbon foot print. Its not for everyone that wants to go faster, but for anyone that appreciates the efficiency.
It would also be great for that same guy in a work truck starting off with a heavy load. The electric motor will lighten the load on the motor while improving torque. It would help improve the highway merge too.
custommotor light bulb.... I’m going to put my ac-51 (because that’s what this is) on my new Chevy truck that I pull a trailer with. LOVE IT I have a fully functioning mini-truck that I converted that has all the parts I need. I have an LH6 that only has 30,000 miles on it.....
Not really a joke. Whatever I have to burn less of to make more power seems like a good deal to me. It looks like a really simple bolt-on kit that I would be willing to throw on my pickup truck.
Mopar Magic ive though of doing something similar with a crx using hubs on the rear(non driven) wheels, but it would cost waaay too much money for little power gain, mpg never crossed my mind once, it wouldnt really be something you use for efficiency. for power though you could use a big*** alternater with li ion batterie(s) and use it like nitrous. this would only really work in small applications... like nitrous, for daily drivers of course. big shots a nitrous are really only good for the "occasional" aka only when you pass a mclaren car or the type of people who blow there strip only car every 200 miles
I love this idea. Keep all these awesome cars on the road, increase hp increase mpg. You can have a hybrid made out of any car you want instead of having to buy some crap-plastic spaceship looking new rig.
Although I am late to the table and this question might have been asked previously, I would be curious about the reliability of a cog pulley system handling 100 HP or more electric motor, especially considering the torque applied to the pulley. At "full throttle" would you not be worried about stripping the belt since you would have literally instantaneous force on the pulley at full torque while the gas engine is just beginning to "spool" up to RPM?
that sounds pretty cool as long as it doesnt cost the world. Like something you can bolt onto your cars crank with minimal modification and get some battery boost and take the strain off the motor.
to me it sounds like you have the ability to have extra torque due to the electric motor plus fuel savings however the price tag for the setup plus a mod plate i think i would rather run slightly more fuel or run a better cam in my ls1
EVL78UC BURNOUT Videos this is the only sound argument against this system. Fabrication and a new motor/controller and batteries will run you $10k. If you didn’t start with an LH and transmission ($10) and went with a beefy motor/controller and more batteries ($15) you would have some range issues but who drives classic cars far anyway.
This has been done on several production vehicles, although usually with a much smaller and less beefy electric motor. Google BAS (Battery alternator starter) hybrid AKA mild hybrid. Sometimes called e-assist. Some manufacturers use this as a cheap, simple way to hybridize a vehicle and remove the alternator/starter, but costs are why the motor is never this big. Also it’s typically done as part of the serpentine belt.
So how does this work in electric-only mode? Does it somehow warm up the oil, or does it just pump cold oil through the engine while it's turning? Because that doesn't sound very good.
There is no electric only mode. The start/stop electric mode turns off the engine at stop lights then when you press the accelerator it starts accelerating on the electric motor which starts the engine as well. It would be horribly inefficient to drive it in electric only mode because you'd be cranking the engine over constantly while you're driving.
All that torque on one end, wonder if it snaps cranks? What about harmonic balance, or is that handled with the aftermarket pulley? Or have you added some sort of bearing/heavier studs on the end? Aftermarket crank?
Nice, i thought about doing this years ago and it's nice to see it in practice. It does take up a lot of room! When i thought about it was before L-ion batteries, so too much weight with lead acid. ...Economy+Performance!
I like the idea of a bolt on system like this, however I would like to see some more real life testing of it before I am sold on it. I have just seen too many "kits" that claim to give you power and better fuel economy, but in reality did nothing.
DC Garage I get that these are in their early stages of being in the market etc. But $5000 is too expensive IMO.....however I would still like to see what these kits actually do on a dyno as well as RL MPG test and before and after on a drag strip
This seems really cool but I have concerns as to the ability of the crank and it's associated bearings in the front to handle that kind or torque coming from that location.
Got a little 2.2l from an s2000 in my shit box corolla, wondering if I could use this as torque fill before it comes on cam to make the power band longer and more linear. Might also be an opportunity to run an insane cam profile and still retain drivability too
I love how he mentioned supercharged but not turbos I have a 65 Oldsmobile with a ls3 and didn't really lose any mpg's and its just wasted energy from the motor that powers turbos. I get that you get a little extra from this but im willing to bet I could buy my car 3 times over for the price of that thing and it looks clunky and odd under the hood
But with turbos or any forced induction you MUST add more fuel to compensate for the added air being pulled into the intake. Will have a MPG loss, but if tuned well it might not be a big hit.
I'd be willing to bet you that you cannot double your fuel mileage with a turbo or supercharger kit. You can with this. However, you must also realize that this is for limited ranges - like most people drive every day back and forth to work - that is less than 80 miles. You will also have to spend a lot of time adjusting your fueling or modifying your engine to be sure that you don't burn valves or pistons. This electric motor doesn't require that. You bolt it on, wire it up and go.
A turbocharger requires low compression, which buggers your low-throttle fuel efficiency, and when on boost, you get awful fuel efficiency from the volumetric efficiency. This is to say nothing of the lost exhaust scavenging and decreased exhaust flow due to the compressor wheel being in the way. Contrary to what turbo manufacturers tell you, there's no such thing as a free lunch.
But is $4500 worth a temporary fuel mileage increase? You would need to allocate that car for daily drive use it for years. I'm sure the system works. I don't doubt the validity. I'm no PhD but the engineering behind it makes perfect sense. But is upgrade worth the fat pile of cash necessary?
I was at 16 mpg before and after the turbo so idk im only running 12 lbs of boost at full throttle but it feels like a ton. Im just saying if I had fuel loss is was very small
does the Honda crz have a electric assist "sport" button that does just this?? I like this set up would love to hear it run. I imagine it requires some engine tuning to get it to all run together.
"I don't like to give up something to gain something"... Well, strapping a giant electric motor to your car, along with all of the batteries needed to run it, is going to add some significant weight to the car, that's giving up something to gain something.
hello @fullboost Do you know if this system will work properly with a lobbed or killer cam style set up? would be a nice to see this ECharger in action soon.
Luisk no like a hybrid. The KERS system harnesses the abilities of economy hybrid vehicles & gears it towards increasing performance. The technology has been used & around since the first gen Prius but for the past 5-7 years or so, many performance manufacturers have begun to see the advantages of hybrid technology. Which is why we now have the KERS system, & why many super/hyper cars uses hybrid technology. It’s awesome I’m enjoying the times we live in right now for cars!
ok, i've been considering doing something like this to my 2000 range rover p38, 4.0 for some time now. I don't have a factory supercharged engine but I know there are some that do and I was contemplating franken-mating a refurbished supercharger drive unit to an electric motor to make the install almost OEM. but Is that even necessary since you say the e-charger can work with any vehicle? My alternate install thought was to mate a PMAC in the driveline but this seems easier by far.
Nick Amarit I totally agree n it's all hinged on battery technology catching up. if it weren't for that only crutch, well weight also, than this would be perfect!!!
These hybrid motors are already on GM cars, though I think they use a much smaller motor & battery pack. Malibu has it. With this one, I'd be worried about snapping the crankshaft if the harmonic balancer can't do its job.
marcus kornegay Wait, it's not? I saw that Vortec name and all I could think of was supercharger. So is it just a 3rd party plug-in hybrid bolt-on system just like in every other plug-in hybrid car then?
Couldn't we just improve the conventional electric starter motors all engines currently already have to improve power & fuel efficiency in a similar way to how this system operates? It seems to me that this idea has been staring us all in the face for years, especially the big car manufacturers.
That is true . The gas motor being an air pump . It just assists. Having said that when the battery goes low or dead , you'll get even worse mileage turning the electric motor with the gas motor . I believe the battery range was really low . Like 60 miles but gotta start somewhere :)
I really like this concept. I have a pickup truck that I do a lot of towing with. With this add-on system, I could put the batteries under the bed out of the way and have more power when I want it. Nice
If it's 'bolt on' how is it 'assisting' the engine? Does it drive the belt it's attached too spinning the main crank pully instead of the crank pully spinning it? That's the only way I can see this 'bolt' on engine assist system working.
How does it know to spin at the right speed and not throw out the engine timing? When to apply power and not to? I originally thought this would be some sort of super / turbo charger assist system to keep them spinning. Better than using anti-lag.
The belt is hooked to the crank. The crank is then hooked to the cams. There's no chance it throws the engine out of timing.... Just like when you crank your car over and the starter doesn't throw the engine out of timing.
Oh durr on me of course. I really was not thinking straight about that yesterday. Thanks for the reminder. It is starting to make more sense now. I think I was thinking about fueling though, would the load on the motor be read the same so the appropriate map cells for the fuel table are read? For open loop of course, I'd like to think yes. So this basically just eliminates the need to use the stored dynamic energy of the spinning assembly, (crank, pulley / balancer, rods, etc), to keep the engine turning during the non power strokes? All motors have a no power portion of the spin which is reduced when you add more cylinders, but you cannot get rid of it entirely. That would add some great efficiencies. If it were used for this I'd imagine you could make that electric motor a lot smaller. Also should be able to get rid of the power drain of the AC. That would be good.
Mike, I am breaking your balls... there is no difference between a motor and a engine any more then a car or an automobile. there, their , they are just judged by context.
I met a guy on the east coast(US) in 2009 or so with a Honda Civic that had a very similar system in his car. He said he made it himself. But instead of batteries he had super capacitors. The thing was fast/quick af...
interesting and well executed concept, but almost certainly be a very expensive, low production, niche market product, in other words, people with 600hp V8's will just use that money elsewhere on the car
This looks very similar to the old GM hybrid setup from around 2009, except this car still has its starter and alternator attached. The old GM hybrids used a belted alternator/starter. One unit.
J it's not about boost. The electric motor assists by giving direct power to the crankshaft. Somewhere around 40% of the energy produced by and engine simply goes into keeping the engine spinning through its cycles. If you add a beefy torquey electric motor to the set up its going to assist the motor much more than if you turbo or supercharged if.
Great idea but the extra weight of needing to carry heavy batteries will counteract the benefit. I know I for one do not want to carry 250 pounds (114 kilos) in extra weight around. As battery technology develops and they get a lot smaller/lighter this idea might become a viable option. Electric motor assisting the conventional motor. Can still run a turbo/supercharger as well.
Yeah battery technology still seems like it's in its infancy but as he mentioned it adds a bit of traction having the weight in the rear so that's somewhat of an advantage if you ask me.
ThomasRocksU actually modern battery technology is far ahead of what this guy is capable if getting his hands on.. The worlds automakers have things in development that this car isn't even coming close to...
I agree, quiet a smart system with the controller having the ability to regenerative engine brake. As mentioned, the benefits and the uptake on such are a system are limited by the availability of higher capacity lite weigh compact batteries.
I’m guessing this system will damage standard and upgraded crank shaft and front mains due to huge hub loads from that torque on the belt as well as the tensioner on that 4” wide belt. Guaranteed this lowers the life of the crank shaft and transmission gears significantly. Just me speculating but I’m guessing the additional loads and vibrations added by this e charger will cause strange failures in the engine block and bearing assemblies.
how much weight does the whole package add?surely it's way heavies then a procharger for example? so is adding the weight actually worse then driving a procharger or anything similar ?
JABBER AEGIS imagine the complete and total shit storm that occurs when the timing chain slips a tooth or breaks. The pistons will be force fed valves and bits of springs.
Tyler Hunt stock crankshafts are not designed to have 200 lb ft of torque applied to the snout. The shaft is going to deflect a lot , throwing the chain out of alignment. This will cause premature tooth wear and crazy ass side loads. The front crank bearings will suffer , causing greater clearance , increasing crank deflection. All these factors will greatly decrease service life and any $$$ you might have saved will be spent on rebuilds - repairs. If you use a aftermarket crank , you just spent over a $1000 plus machine work. Unless you're using $200 junkyard motors or only drive it 2000 miles a year , the risk/reward is too off balanced for me to invest.
BustedWalletGarage None of that answers my question. You're not going to have enough deflection in the crank to jump a tooth on the timing chain without catastrophic bearing failure first.
Does the electric motor disengage when it's not being used/powered by the batteries or is the engine then forced to turn that electric motor? Can the gas engine be used to charge the batteries?
They describe it themselves as an "electronic supercharger" which is a really stupid click-bait description, and only leads to further confusion about what the thing actually DOES.
I don't see it fitting under the hood of my 94 lt1 vette... Power to weight, thinking handling and performance. Sure, another 100 ft lbs, but what does that transfer too as far as extra weight to move and extra strain on the rest of the car?
This is like a way beefed up system that I was thinking about as an addition to a turbocharged car!

Jerry Bear replace the torque converter with an electric/hydraulic motor. Easily adaptable to any conventional transmission platform.

so it doesn't force air into the engine, it helps turn the crank via cog belt? how often do you need belt replacements?
That's correct.
Every hundred thousand miles or so.
toysareforboys I find that hard to believe...
Have you ever noticed how many brands of motorcycle have gone to belt final drive lately? Nuff said.
Dorian Demeturlias not a single performance oriented bike has gone to a belt drive... only mid life crisis I need my wife's permission type bikes...
this is the first (ev hybrid vehicle) video where the guy is talking like he knows what he's saying, that really made me smile
Instead of calling a true bolt on hybrid , it should just be called a hybrid assist.
Why?
Is it not just a big starter motor?
Actually old news. This has been around in the UK for awhile. Big rigs or lorries as they call them have had electric assist for years. Helps pull heavy loads uphill while reducing fuel consumption.
+TH3TIMP5 looks like an industrial 3 phase 480 electric motor. Don't know the specs but have that style in a plant I work in.
CorndogBrownie yup I think that is a marketing gimmick.we are familiar with hybrid so they call it that
is there anything that hasn't been tested on a 5.3 vortec lol
LS Bro!
codemanz191 was a 6.0 lol even better.
zechariah smith then 6.0s chug !!!!! im cool with a 5.3.. its fast enough to drift etc
They have yet to determine whether or not it can run off of peanut oil and broken dreams.
codemanz191 6.0 vortec
DYNO SHEETS OR IT DIDN'T HAPPEN... talk is cheap and numbers don't lie folks
Numbers lie when its the imperial system....
Ppl always wanna bring up Dyno sheets
More like 11mpg
Must wash out unburned fuel
Jr alexander sounds good did you fully rebuild your top end and also do you use P.T.F.E eg..slick 50 to line up the sleeves coz that’s pretty impressive
They may have a slightly better market for a larger truck. I think a lot of truck owners who use them for work (small business) would probably SERIOUSLY consider it if it can save / make them money over the long haul in gas savings. Especially if it helps their towing capabilities.
I think a lot of people are missing the point... this isn't an electric super charger or a "power adder". it is a universal system that reduces load on the engine. the effect is more of the engines power being used to turn the wheels, not being waster on drag. its a proof of concept and I think its going in the right direction. How about the guy that has a work truck (LS V8...) and doesn't want to keep making the fuel payments (cash and environmentally), he can add this system to greatly reduce carbon foot print. Its not for everyone that wants to go faster, but for anyone that appreciates the efficiency.
It would also be great for that same guy in a work truck starting off with a heavy load. The electric motor will lighten the load on the motor while improving torque. It would help improve the highway merge too.
custommotor light bulb.... I’m going to put my ac-51 (because that’s what this is) on my new Chevy truck that I pull a trailer with. LOVE IT I have a fully functioning mini-truck that I converted that has all the parts I need. I have an LH6 that only has 30,000 miles on it.....
Well thought it was interesting but I clicked on the link and the website can’t provide a secure server or whatever it said 🤨
I'm all for burning dinosaurs but this is a REALLY cool idea.
Joke's on you, oil is 99.9% algae.
Not really a joke. Whatever I have to burn less of to make more power seems like a good deal to me. It looks like a really simple bolt-on kit that I would be willing to throw on my pickup truck.
Mopar Magic ive though of doing something similar with a crx using hubs on the rear(non driven) wheels, but it would cost waaay too much money for little power gain, mpg never crossed my mind once, it wouldnt really be something you use for efficiency. for power though you could use a big*** alternater with li ion batterie(s) and use it like nitrous. this would only really work in small applications... like nitrous, for daily drivers of course. big shots a nitrous are really only good for the "occasional" aka only when you pass a mclaren car or the type of people who blow there strip only car every 200 miles
Mopar Magic gas is king
I love this idea. Keep all these awesome cars on the road, increase hp increase mpg. You can have a hybrid made out of any car you want instead of having to buy some crap-plastic spaceship looking new rig.
What happened to this concept ? Tried to look for the site and it no longer there did they go bust 🥺
Although I am late to the table and this question might have been asked previously, I would be curious about the reliability of a cog pulley system handling 100 HP or more electric motor, especially considering the torque applied to the pulley. At "full throttle" would you not be worried about stripping the belt since you would have literally instantaneous force on the pulley at full torque while the gas engine is just beginning to "spool" up to RPM?
It's no different than a supercharger that needs 100ish hp to drive, the force is just in the opposite direction if that makes sense
that sounds pretty cool as long as it doesnt cost the world. Like something you can bolt onto your cars crank with minimal modification and get some battery boost and take the strain off the motor.
to me it sounds like you have the ability to have extra torque due to the electric motor plus fuel savings however the price tag for the setup plus a mod plate i think i would rather run slightly more fuel or run a better cam in my ls1
EVL78UC BURNOUT Videos this is the only sound argument against this system. Fabrication and a new motor/controller and batteries will run you $10k. If you didn’t start with an LH and transmission ($10) and went with a beefy motor/controller and more batteries ($15) you would have some range issues but who drives classic cars far anyway.
This has been done on several production vehicles, although usually with a much smaller and less beefy electric motor. Google BAS (Battery alternator starter) hybrid AKA mild hybrid. Sometimes called e-assist. Some manufacturers use this as a cheap, simple way to hybridize a vehicle and remove the alternator/starter, but costs are why the motor is never this big. Also it’s typically done as part of the serpentine belt.
This is actually pretty brilliant. So simple. Why didn't I think of that.
I basically discovered this because I thought of it as a concept but then though wait that’s way to simple and long story short it is already a thing
Why isn't anyone putting a Hyper9 or something in line with the driveshaft?
So how does this work in electric-only mode? Does it somehow warm up the oil, or does it just pump cold oil through the engine while it's turning? Because that doesn't sound very good.
No it doesn't drive the wheels it aids the motor, so it uses less fuel.
So driving with only the electric motor and not using fuel isn't possible?
correct, they work together.
There is no electric only mode. The start/stop electric mode turns off the engine at stop lights then when you press the accelerator it starts accelerating on the electric motor which starts the engine as well. It would be horribly inefficient to drive it in electric only mode because you'd be cranking the engine over constantly while you're driving.
Finally someone understands. You'd be fighting against a ton of engine compression. It would be a massive waste of energy in electric only mode.
Can this system be adapted on to something like a 93 Civic with a 1.5 liter engine for super economy mode?
You mean the Civic Hybrid?
Is there a video of this car's performance?
All that torque on one end, wonder if it snaps cranks? What about harmonic balance, or is that handled with the aftermarket pulley? Or have you added some sort of bearing/heavier studs on the end? Aftermarket crank?
oh cool, a giant alternator.
That's really all it is , a motor to force your psitins up and down without fuel going in , sounds dangerous to me
This is the literal stupidest “power adder” I’ve seen
@@mechanicmatt9466 there is no issue there. as long as there is oil pressure, it doesnt matter if there is fuel
@@Demonslayer20111 there will always be oil pressure because the pump runs off the snout of the crank .
Lol it can't be an alternator if it starts the car lmao learn your shit it's an electric motor
Nice, i thought about doing this years ago and it's nice to see it in practice. It does take up a lot of room! When i thought about it was before L-ion batteries, so too much weight with lead acid. ...Economy+Performance!
I like the idea of a bolt on system like this, however I would like to see some more real life testing of it before I am sold on it. I have just seen too many "kits" that claim to give you power and better fuel economy, but in reality did nothing.
The difference is this kit is based on proven technology. Of course that means it will probably be VERY pricey...
+DC Garage I believe they are aiming to sell the kit for under $US 5000.
Fullboost Wow that's actually not bad! I would strongly consider it at that price.
DC Garage I get that these are in their early stages of being in the market etc. But $5000 is too expensive IMO.....however I would still like to see what these kits actually do on a dyno as well as RL MPG test and before and after on a drag strip
IMMORTEN VALKYRIEN dude 5 grand is a steal. I really want a kit now
This seems really cool but I have concerns as to the ability of the crank and it's associated bearings in the front to handle that kind or torque coming from that location.
just a helper motor. big golf cart motor with a pulley and belt
I would love to drive that 150hp golf cart :D
50KW motor. Horsepower = KiloWatts x 1.73 = 86.5HP
Nathan Scantling oh I see - mixed it up, but it would still be an impressive motor for a golf car!
yes i know how much hp it is lol
is it x1.73? :o when i use the google calculator it gives me 67hp
Got a little 2.2l from an s2000 in my shit box corolla, wondering if I could use this as torque fill before it comes on cam to make the power band longer and more linear. Might also be an opportunity to run an insane cam profile and still retain drivability too
Cool aftermarket electrical solution
Battery cells are Panasonic NP2? Did u have to do any cycling and how long did ur assembly last?
I love how he mentioned supercharged but not turbos I have a 65 Oldsmobile with a ls3 and didn't really lose any mpg's and its just wasted energy from the motor that powers turbos. I get that you get a little extra from this but im willing to bet I could buy my car 3 times over for the price of that thing and it looks clunky and odd under the hood
But with turbos or any forced induction you MUST add more fuel to compensate for the added air being pulled into the intake. Will have a MPG loss, but if tuned well it might not be a big hit.
I'd be willing to bet you that you cannot double your fuel mileage with a turbo or supercharger kit. You can with this. However, you must also realize that this is for limited ranges - like most people drive every day back and forth to work - that is less than 80 miles. You will also have to spend a lot of time adjusting your fueling or modifying your engine to be sure that you don't burn valves or pistons. This electric motor doesn't require that. You bolt it on, wire it up and go.
A turbocharger requires low compression, which buggers your low-throttle fuel efficiency, and when on boost, you get awful fuel efficiency from the volumetric efficiency. This is to say nothing of the lost exhaust scavenging and decreased exhaust flow due to the compressor wheel being in the way.
Contrary to what turbo manufacturers tell you, there's no such thing as a free lunch.
But is $4500 worth a temporary fuel mileage increase? You would need to allocate that car for daily drive use it for years. I'm sure the system works. I don't doubt the validity. I'm no PhD but the engineering behind it makes perfect sense. But is upgrade worth the fat pile of cash necessary?
I was at 16 mpg before and after the turbo so idk im only running 12 lbs of boost at full throttle but it feels like a ton. Im just saying if I had fuel loss is was very small
does the Honda crz have a electric assist "sport" button that does just this?? I like this set up would love to hear it run. I imagine it requires some engine tuning to get it to all run together.
THAT would add quite some fun to a Miata!
That's pretty cool, I would get something like this and it will be interesting to see how far these sort of systems get developed.
I'd love to know how much the whole system weighs. No point in adding all that gear if the power added cannot overcome that additional weight.
Bestwick1983 you would have to add a whole lot of weight to make 150 horsepower a waste
They told on the video that it was under 250 pounds.
Jd Rogers II this is an ac-51 ac induction 3phase motor. It produces 148 foot pounds and 51kw of power which is 68.4 hp
Would the ecm and fuel management systems function correctly? For that matter, why assist at the crank? Put it on the drive shaft or something.
"I don't like to give up something to gain something"... Well, strapping a giant electric motor to your car, along with all of the batteries needed to run it, is going to add some significant weight to the car, that's giving up something to gain something.
He was talking about energy, but if you strap on any kind of kit, it will add weight.
You're gonna have to give up a lot of money to buy and install this stuff . I don't think you're going to get your money back with the gas savings.
But you gain traction . lol . Like is enough weight already on that car . To get some extra benefit on traction thanks to weight .
hello @fullboost Do you know if this system will work properly with a lobbed or killer cam style set up? would be a nice to see this ECharger in action soon.
starter motor beefed up and geared
Not at all this thing is much much larger and likely bushless.
Haven't you got any grammar to police?
This is also a three phase a.c. motor.
Everyone loves this LS motor, I want one in my Golf. Put a full cam, multi-spark, blower, some other stuff, road runner horn, total sleeper.
Regenerative braking? Kinda like the KERS system?
Or like any hybrid on the market....
Luisk no like a hybrid. The KERS system harnesses the abilities of economy hybrid vehicles & gears it towards increasing performance. The technology has been used & around since the first gen Prius but for the past 5-7 years or so, many performance manufacturers have begun to see the advantages of hybrid technology. Which is why we now have the KERS system, & why many super/hyper cars uses hybrid technology. It’s awesome I’m enjoying the times we live in right now for cars!
Luisk this isnt grand theft auto bud
KERS has been around long before GTA was a thought. Nice try though.
He was explaining it, not claiming the tech as his own, just that it had the function
ok, i've been considering doing something like this to my 2000 range rover p38, 4.0 for some time now. I don't have a factory supercharged engine but I know there are some that do and I was contemplating franken-mating a refurbished supercharger drive unit to an electric motor to make the install almost OEM. but Is that even necessary since you say the e-charger can work with any vehicle? My alternate install thought was to mate a PMAC in the driveline but this seems easier by far.
If this tech is really that good, then shouldn't it be provided as standard equipment on all cars in the near future?
Nick Amarit I totally agree n it's all hinged on battery technology catching up. if it weren't for that only crutch, well weight also, than this would be perfect!!!
These hybrid motors are already on GM cars, though I think they use a much smaller motor & battery pack. Malibu has it. With this one, I'd be worried about snapping the crankshaft if the harmonic balancer can't do its job.
vidznstuff1 But the electric motors in the Malibu don't drive a Supercharger.
this isn't a super charger
marcus kornegay Wait, it's not? I saw that Vortec name and all I could think of was supercharger. So is it just a 3rd party plug-in hybrid bolt-on system just like in every other plug-in hybrid car then?
so it helps make power by assisting the serpentine system? or does it actually force air into the engine?
Couldn't we just improve the conventional electric starter motors all engines currently already have to improve power & fuel efficiency in a similar way to how this system operates? It seems to me that this idea has been staring us all in the face for years, especially the big car manufacturers.
Mark Leadbeater manufacturers are doing it already .
I mean. This system is pretty crude delivering it's power via a belt to the crank.
That is true . The gas motor being an air pump . It just assists. Having said that when the battery goes low or dead , you'll get even worse mileage turning the electric motor with the gas motor . I believe the battery range was really low . Like 60 miles but gotta start somewhere :)
I believe that is what Christian Koenigsegg has developed for his new car. Ties straight into the flywheel/torque converter I believe.
search RUclips for /Inside Koenigsegg
I really like this concept.
I have a pickup truck that I do a lot of towing with. With this add-on system, I could put the batteries under the bed out of the way and have more power when I want it.
Nice
So is it boost?
No, as stated in the video, it gives assisted drive to the engine.
Fullboost oh okay, makes sense.
Ryan Austin no , it's a " High Bert ". FYI , kids will be going down the streets in the dead of night , unplugging " HIGH BERT " cars.
If it's 'bolt on' how is it 'assisting' the engine? Does it drive the belt it's attached too spinning the main crank pully instead of the crank pully spinning it? That's the only way I can see this 'bolt' on engine assist system working.
+adamwilson301 yes, that's how it works.
How does it know to spin at the right speed and not throw out the engine timing? When to apply power and not to? I originally thought this would be some sort of super / turbo charger assist system to keep them spinning. Better than using anti-lag.
The belt is hooked to the crank. The crank is then hooked to the cams. There's no chance it throws the engine out of timing.... Just like when you crank your car over and the starter doesn't throw the engine out of timing.
Oh durr on me of course. I really was not thinking straight about that yesterday. Thanks for the reminder. It is starting to make more sense now. I think I was thinking about fueling though, would the load on the motor be read the same so the appropriate map cells for the fuel table are read? For open loop of course, I'd like to think yes. So this basically just eliminates the need to use the stored dynamic energy of the spinning assembly, (crank, pulley / balancer, rods, etc), to keep the engine turning during the non power strokes? All motors have a no power portion of the spin which is reduced when you add more cylinders, but you cannot get rid of it entirely. That would add some great efficiencies. If it were used for this I'd imagine you could make that electric motor a lot smaller. Also should be able to get rid of the power drain of the AC. That would be good.
car is very interesting, but I am a Porsche guy and would loved to have seen the 911s parked behind it !
That's a great system and something I think will be popping up more often from car companies
this guy needs to learn the difference between a motor and engine.
What is the difference ?....cuss I have a outboard motor in my boat.... should I worry about getting electrocuted ?
I believe you have an outboard engine on your boat. An inboard engine would be in.
Mike, I am breaking your balls... there is no difference between a motor and a engine any more then a car or an automobile. there, their , they are just judged by context.
At 4:25 he said cost saving vs paying $5 to $10 a gallon for premium gas. Im wondering what country hes getting these prices from
I just want an F1 style K.E.R.S. button. Turbo BOOST!

Alex Romo What the HELL is the matter with your brain??? The background music is beautiful!!!
This background music made me kill myself.
drongo jonkins And I'll bet background music which actually kills most people {such as Screaming Heavy Metal} would make you come alive.
drongo jonkins Only if that's what you choose to believe. The decision is ultimately yours to decide.
Interesting. Any front main bearing issues from the belt?
interesting and well executed concept, but almost certainly be a very expensive, low production, niche market product, in other words, people with 600hp V8's will just use that money elsewhere on the car
wrong.
This looks very similar to the old GM hybrid setup from around 2009, except this car still has its starter and alternator attached. The old GM hybrids used a belted alternator/starter. One unit.
I see way more cons then pro's with this set up
Franky's SpeedShop Agreed. Do away with the LS motor all together. Its ancient technology. Put a big fat tesla motor in there!
Kyle Haley tesla uses an electric motor on each wheel...
J it's not about boost. The electric motor assists by giving direct power to the crankshaft. Somewhere around 40% of the energy produced by and engine simply goes into keeping the engine spinning through its cycles. If you add a beefy torquey electric motor to the set up its going to assist the motor much more than if you turbo or supercharged if.
Uses a motor on each axle, not wheel.
Mr S Technically two in the rear and one in the front on current models. And the first Tesla Roadster had one, fat, electric motor.
so if this is powered by the crank , could you still put a traditional supercharger on it and keep this new type on?
Great idea but the extra weight of needing to carry heavy batteries will counteract the benefit. I know I for one do not want to carry 250 pounds (114 kilos) in extra weight around. As battery technology develops and they get a lot smaller/lighter this idea might become a viable option. Electric motor assisting the conventional motor. Can still run a turbo/supercharger as well.
Yeah battery technology still seems like it's in its infancy but as he mentioned it adds a bit of traction having the weight in the rear so that's somewhat of an advantage if you ask me.
Modern battery technology is so far behind, probably for a reason
ThomasRocksU actually modern battery technology is far ahead of what this guy is capable if getting his hands on.. The worlds automakers have things in development that this car isn't even coming close to...
I agree, quiet a smart system with the controller having the ability to regenerative engine brake.
As mentioned, the benefits and the uptake on such are a system are limited by the availability of higher capacity lite weigh compact batteries.
Stephen H combined the entire system added is at min 400 lbs. The motor alone is ~70 lbs
Very nice build! I love what he did with the holes left in the body from the aluminum stainless trim.
RWB Porsche behind it
Geordie and Luke,
You guys have come along way from the good old days of ET Pulsar and Cordia.
Well done fellas.
Thanks dude ;-)
'Jonathan Goodwin of from E-Charger' in the description. Little mistake.
jezwah Dont forget about those twin spark Gazelles😂
IKR, I just subbed
that's cool as funk
I’m guessing this system will damage standard and upgraded crank shaft and front mains due to huge hub loads from that torque on the belt as well as the tensioner on that 4” wide belt. Guaranteed this lowers the life of the crank shaft and transmission gears significantly. Just me speculating but I’m guessing the additional loads and vibrations added by this e charger will cause strange failures in the engine block and bearing assemblies.
after he said it doesn't make boost...next video lol
how much weight does the whole package add?surely it's way heavies then a procharger for example? so is adding the weight actually worse then driving a procharger or anything similar ?
can you say crankwalk with the electric motor pulling on the crank pulley.
JABBER AEGIS imagine the complete and total shit storm that occurs when the timing chain slips a tooth or breaks. The pistons will be force fed valves and bits of springs.
Why would the timing chain slip a tooth?
Tyler Hunt stock crankshafts are not designed to have 200 lb ft of torque applied to the snout. The shaft is going to deflect a lot , throwing the chain out of alignment. This will cause premature tooth wear and crazy ass side loads. The front crank bearings will suffer , causing greater clearance , increasing crank deflection. All these factors will greatly decrease service life and any $$$ you might have saved will be spent on rebuilds - repairs. If you use a aftermarket crank , you just spent over a $1000 plus machine work. Unless you're using $200 junkyard motors or only drive it 2000 miles a year , the risk/reward is too off balanced for me to invest.
BustedWalletGarage
None of that answers my question. You're not going to have enough deflection in the crank to jump a tooth on the timing chain without catastrophic bearing failure first.
BustedWalletGarage
Also, do you see a lot of jumped timing chains in supercharged vehicles?
Does the electric motor disengage when it's not being used/powered by the batteries or is the engine then forced to turn that electric motor? Can the gas engine be used to charge the batteries?
Wtf is with the big ass Alternator!?
lol what?
pop eye lmao same thing i was thinking, like these dudes just did all of this to create a performance alternator 😂😂
An alternator that assists the engine power?
Website doesnt exist anymore? Are these guys still working these kits?
This Fullboost presenter has no personality, always the same drab monotone voice in every video. Cheer up bro, you have an awesome job 😂
What happened to this? Why didn’t it take off?
Put it on a dyno bra!
Where can I get this in Australia 🇦🇺. Does it come in kit form.Voltage range min - max.? It would be great to get a response
music is annoying as hell
I need one for a 4afe 90 corolla motor bolt on. As well can we install this to the toyota prius too?
all that extra power is useless when compared to all the weight. no Pros. here just a big con.
rich fortner it's the platform that's the pro. u can use this setup on any car. Ur focused on the wrong part of the equation my friend.
No, not really. The electric motor can move that extra weight with less energy required than the gasoline engine can.
andTo861 150 ft. lbs. not 150 horsepower . big difference .
rich fortner this is an ac-51 ac induction 3phase motor. It produces 148 foot pounds and 51kw of power which is 68.4 hp
How is it more economical if you have to charge it as well as putting petrol/diesel fuel in?
how or why asking about boost coming from an electric motor is beyond me lol
It's "boost" because it's boosting the engine's power level by augmenting it with said electric motor.
The thing is that the electric motors have huge torque right from the start till the end.
They describe it themselves as an "electronic supercharger" which is a really stupid click-bait description, and only leads to further confusion about what the thing actually DOES.
I don't see it fitting under the hood of my 94 lt1 vette...
Power to weight, thinking handling and performance. Sure, another 100 ft lbs, but what does that transfer too as far as extra weight to move and extra strain on the rest of the car?
