jake stockton: Coming from a mechanic, these are gimmicks. End of story. Move along everyone. There's nothing more to see here. 

Daimon Hill: To all the people saying "Not Possible" ... you realise that for around $50 you can get a 40,000 RPM brushless (90% efficiency) RC helicopter motor that is approx 1.2Kw and puts out around 2NM torque, and is 36mm x 65mm in size (Turnigy XK series) Sure, it draws 80A max, and sure an ESC (Electronic Speed Controller) will run you another $100, and would probably only make 3 or so PSI... but thats with a FEW minutes of looking... you can get some REALLY impressive brushless DC motors if you know where to look

너 자신 치유: if you get a turbo charger or a super charger why go through all the trouble modifying it and slapping on an electric motor when u can just use the it in the car? lol

Fajar Wahyu: Instead of " I feel" or "I think"..it is better if you prove it by the number, say, from the dyno test..from both of you, the fan of real compressed turbo, and the fan of electric turbo device..

ProRockJK: Ok this freaker down here keeps saying my electric turbo makes boost blah blah blah blah My English sucks so what but I least I'm not dumb like you that thinks that lil pice of crap will make boost or power to the engine Just saying you get more air driving in the freeway to your engine than that crap just saying 

TheDudeAr: Why WOULDN'T an electric supercharger work? The only difference between electric vs mechanically driven is just that. There will be a parasitic loss of driving the generator off the crank to create the power to drive the electric supercharger, but this is NO different than a mechanical superchargers belt coupled to the crank pullet. An electric driven supercharger will have slightly less efficiency due to having to convert the energy to electric and again back to mechanical at the supercharger, losses will be in the form of heat. Someone slap one on already to shut these internet know it alls up. - Power Engineer

Alexander B.: I don't understand why people on here are saying that turberchargers don't work. Do they even understand how COMPRESSED MAF works? It's been proven already. There's math that goes along with it to explain it.

Frank Furter: WHY is it that you think you'd need all of those batteries if the alternators are pumping out gobs of power in the numbers that you cited? How long do you think anyone would need to run the alternators to run the equivalent HP in an AC motor like you cited from Baldor? Constantly? What are the RPM of that electric motor? It's probably like around 1,725 or so, and that is why it needs to be such a honkin' beast to make 30 HP. And it's most likely a 440/460V 3 phase AC motor too. Do you know what the differences are between AC motors and DC motors? Stop and think here for a minute or two, PLEASE! Deep cycle batteries are able to take a bit more abuse than standard automotive ones, but they're not the end of all creation. How far down do you think you'd be drawing down a battery of any type for a sporadic use such as this anyway? Batteries store electrons in the acid electrolyte, that's why the specific gravity changes when the battery is charged up and is discharged. Distilled water is used in batteries to keep the concentration of the H2SO4 at the correct percentage rather than tap water because the dissolved minerals will cause problems. But in all of this, I never once said anything to advocate using an electric motor to run a super charger, did I? Maybe it can be done with a permanent magnet starter motor that has been modified for short bursts of power, but NOT for continuous duty as you seem to think would be the situation. Randy

tuscolian: To create a device like this, you need to understand the engineering of physics and aerodynamics. Using a turbocharger compressor gets you part way there as they have a pressure map. The turbo is an air compressor and an engine is an air pump. To develop pressure between them, you need to produce more air volume than the engine requires normally.You would need to spin the shaft at increasing speed with an increased RPM of the engine. I takes a lot of HP to produce that much volume and pressure. I'm skeptical of how economical an electric motor big enough to make that much HP would be, not to mention a high power motor controller.

Roger Colinayo: i think electric supercharger / turbocharger are good for eliminating the turbo lag. If we can use twin turbo one electric turbo and 1 conventional turbo during low rpm engine, electric turbo can help create pressure instantaneously then at a certain speed the conventional turbo will fill in as the engine back pressure is increasing.

stujb: Assuming this does do as you say, what about all the other important factors? If you force more air into the engine, then you need to increase fuel into the chamber. If you increase fuel you will also need to adjust the point of spark. You can't just increase air flow and gain power. You need to adjust everything. 

Joshua Naranjo: F1 cars use something similar but it's complicated cross between a turbo, electric pulled, and a generator with a management system...supposedly incredible gas mileage,torque and power. Of course tons more involvement on the engineering side of things

Stefan Cvetanovic: hello ! i have one question . i saw electric superchargers on ebay ,and i was wondering ,can i install this kind of supercharger on my kymco agility 50 ccm scooter? :D

Tim Spriggs: what about this? ... http://www.zoro.com/i/G3418791/?utm_source=google_shopping&utm_medium=cpc&utm_campaign=Google_Shopping_Feed&gclid=Cj0KEQiAn9-kBRDloNeUw7Pe_YwBEiQA4HXMU2L__s_M55OWU3uzzaRsqnchHKitz9uJvUrD8cDyxc8aAiRT8P8HAQ 

Eric Nutter: I want to know how long a battery can sustain the current required to spin that motor at the 20,000 to 30,000 rpm required to get boost.

Honesty Counts: For a true electric supercharger to work it has to have a LOT OF POWER, at least 20 to 40 hp motor attached to it, and a motor like that is as large as the typical car battery, so you will need a lot of room in the engine bay just for that alone and that's usually not possible. For that much power you are going to need a wire to the motor that is as thick as the wire that connects to your battery terminals, at least 1/4" diameter copper. That much power draw will stall your car because all of the battery power will be sucked right to the turbo unit, so you will need a separate battery system just to power the turbo itself. What happens then is that the electric turbo is off most of the time under normal conditions and the air enters the engine through the 'normal' non-turbo air intake. At this time the car's electrical system slowly re-charges the turbo's separate battery. Then when you need a sudden boost of power, you hit a switch on the steering and the turbo battery disconnects from the car's main electrical supply, and the turbo sucks power from the separate turbo battery only, the extra boost of air enters the regular air intake from a separate side pipe, and this extra pressure then closes a flapper valve on the air intake to prevent boost air from exiting out the air intake. The boost air then enters the engine at much higher pressures than normal. This boost can be maintained for only as long as the separate boost battery can supply power, which is not that long. As soon as the electric turbo starts to die down, the boost pressure falls down, the intake flapper valve then opens up and air enters the engine using the normal air intake route, not from the turbo. This system can work wonders but it is very complicated, very large, and very heavy, and is very seldom used because of those factors. A much simpler and much smaller idea is to just use NOS instead (Nitrous Oxide), it gives the same results as the above '2-intake' electric supercharger system and won't need a huge amount of space under the engine for the entire setup.

Tom Tangle: Im tryna figure out the mechanical electrical relationship... Does the power created from the car battery spin the impellar to specific speeds depending on rpm ? 

ThatGUY1027: An electric supercharger could work if you had a powerful enough electric motor. I can tell you right now, that little brushless motor will not be strong enough... It might spin it up to your desired rpm but as soon as it is loaded from boost it will not keep up. I worked for a ProCharger dealer and have extencive experience with both installation, designing of mounts and drive systems. I have personally seen the larger blowers bend/break/flex thick billet mounts and break large cogged belts! For an extreme example the F2 ProCharger with an impeller speed of 61,264 RPM making 32.9 Psi of boost has a parasitic HP loss of 353.6 HP!!!!!!!! here is a quick article on some ProCharger testing http://www.dragzine.com/news/lose-power-to-make-power-procharger-parasitic-loss-testing/ -Automotive Engineer

Peter Gotham: electric super chargers do not work

Caleb Anderson: I wanna buy one where can i get one

metralha761: Hi, thanks for that explanation in the video! I'm trying to find asynchronous supercharger project, well at least is what I call it. Why call that? the concept is between the conventional turbo charger and an electric super charger, with what I have in my mind, I think it's possible to have high pressure with electric super charger.

epcenter5hz: This Guy sounds like "Just Blaze"

Andres Perez: 1) So this electric supercharger can compress air and produce boost because the motor can spin at high RPM? 2) How much torque does the electric motor have at these RPM? 3) How much back-pressure can it take before having any kind of compressor surge? 4) How is the impeller speed controlled for different RPMs and boost settings? 5) Did you adjust the OEM compressor map for the air resistance vs electric power?

no bad words hash: thanks a lot 

Loretta Bain: What's for dinner dude?

2bidfilmsguy: wouldn't it just be a better idea to run an electric motor up to a centrifugal supercharger? instead of having the pulley run by a belt off the engine it could just be mated to a motor, and that way hypothetically you could make peak boost almost instantly rather than at red line which would be a drawback of the same supercharger being run off an engine belt

Fred Perez: where is an actual video of a real test on a car in a dyno

janoah365: man build me one..lol

Tyler Looney: how did you make that real supercharger into an electric supercharger i would love to know, because im in the process of building up my 98 chevy metro into a custom turbo gasser but i dont have alot of money to do much. so i would love to know how to make and install your custom prototype electric supercharger. please make a video in the near future on how to construct and install the prototype. thank you

NeverEnough: Hey Bro, your link to the build is dead. I'd like to see your plans. Thanks.

Jr Ram: Where can I buy one

Jacob Regamey: any updates? what motor is ideal? what rpm for how much pressure etc

Anthony Gillian: the turbo makes boost because it spins at 100,000X a minute, while your electric fan is just wasting electricity 

hotpapayasalad: according to ohms law it doesn't work. you're taking power to make power and what's worst you're taking power from the electric system from your vehicle which it need the most. your lights will dim, your spark plug will not fire to its full potential which results lost in horsepower and poor gas mileage. its like adding a stereo system in your car with out any modification done. any INDUCTIVE LOAD such as elector motor will pull mass amount of juice. you'll over work your alternator!!!

Rob Sewell: Where can I get one will it work on a 98 maxima

skeggjold gunnr: Of course a real compressor impeller creates boost! Why ask "does it work"? What, you're hung up on the *source* of drive power? WHY? Electricity can be controlled more easily and have none of the drawbacks of exhaust gasses or a crankshaft / belt drive. Electric motors can provide WAY more RPM's (with belt / pulley) and WAY more torque than you could ever use...and do it more efficiently. This IS the answer for the smart. Great job on a great video!

ProRockJK: This crap don't make no boost!!!! Put it in a Dino bro. 

jayden hewer: Electric superchargers are a great idea if pushed into production for people like me who wants to increase there performance without getting down and dirty with manifolds and drive belt systems. people like me would be happy with 3-4 psi of boost, if you want 18 psi get a turbocharger. Do you foresee electric turbos being available to the consumer any time soon? Is a system the is natural aspirated when the supercharger is off a possibility? This would be excellent for a capacitor system. 

Danny Hoadley: Jesus Christ there are so many electrical and mechanical engineers out there who can't seem to agree on the conservation of energy. The creator of electric superchargers/turbos must know how to bend the laws of physics. My mind is blown.

casey james: the outlet in the motor?Nope later

Daniel Allison: how can I get one of those electric superchargers? looks more legit than those ebay ones cant find them on your site

Dave theWorker: nice man good explanation of how a turbo works and these ebay guys are pickles

MIKE J: you got any dyno videos

PP van dorst: lets sie some dyno testing

Ciber: What if you buy one of those electric ones and connect a little weed eater 2 stroke engine to the fan to make it turn faster? That would create some compression.

HomasterX: the 2nd prototype looks promising

Ronald Holley: Ok I'm looking at a electric supercharger that's 60 amps and 837 watts I think and 1psi I can give u the name if u need it just email me and I'll give u more info and says it can give me a 5 to 10 percent more hp what do u think 

Dragonstud: awesome explanation, I'd like to add one of your turbos to my 2 stroke....how much are they?

Kuba Fly: Where can i buy your shizzz!!!

Blue Rebublic: The scam is basically just a fan powered cold air intake. There is no benefit to having one unless you want to be able to tell your friends that you have a supercharger in your car, but the truth is you only paid $20 USD for it. You might as well have a leaf blower as an intake.
