Did a search didn't find anything about this (electric super chargers), only a weed wacker thingy and flaming on this concept.

Even though it's for small motors. Just thought people would like to know.

Only puts out 405cfm@5.5psi for 15seconds.

 

alot where on ebay and alot of people bought them, on here there were alot of threads about them they dont seem to be a high horsepower maker

 

Note that the applications are for 2.5 litre engines and under.

 

Sounds like a joke to me. I too saw the eBay auctions for these. I don't think that a cars electrical system could support an electric supercharger that would make enough boost to be noticeable. The system looks more like motorized ram air than a supercharger. Neat gimmick, but I can't believe that it would actually work.

 

Don't bother with them, it just a bunch of BS do a search on here theres a bunch of posts about them and those tornado fuel saver things .

 

There are electric supercharges out there. Not the one that you have there, but there is a type of electric supercharger that is quite nice. It is a centrifugal supercharger with an electric motor to turn the turbine and a blowoff valve thing to regulate boost. It was a 454 in a 2nd gen camaro. Ran 6s in the 1/8th mile he was hoping for 5s though.

 

I don't buy that. The size of the electric motor needed to spin a blower capable of producing enough boost to get a car to run that fast would be way too heavy to allow it to run that fast. Also, the hardware required to generate enough electricity to power a sufficiently sized electric motor would make the car even heavier.

The physics required to make it work create far too many limitations. Think about how big and heavy a 5HP motor on an air compressor is, and then imagine how big and heavy a 150HP electric motor would be. It takes a lot of power to spin a blower hard and fast enough to make even 7 psi. The ones used in Top Fuel consume over 1,000 HP just to spin the blower.

Maybe at some point someone experimented with this type of technology, but there's a reason it never caught on in the mainstream.

 

Actually, given the nature of battery and electric motor technology these days, this is very possible.

 

I've got to disagree with that. If battery and electric motor technology has come far enough to enable it to power a supercharger with a favorable power to weight ratio, then we'd have decent electric cars by now.

The whole reason this technology is still in it's infancy is that automakers and oil companies have conspired to keep it that way, because it isn't conducive to their proffit margins.

 

why pay $2000 for an electric setup when you can buy a real supercharger for about the same?

 

dont ever buy thomas knight products
they are a joke
there have been people o nprobetalk.com buying his setups and they all end up blowing up after 5000 miles
he is a joke when it comes to his cars
and knows nothing

i would never buy something from him

 

why does it take 5hp to run a blower? I tested mine with a drill I know I am not turning it fast enough but, with the pulley on the drill it would make up the differance. and sorry but the drill is not 5hp I could see it working. my power inverter runs the drill easy. the only thing is It is easyer to just run it off the crank. my only point is an electric supercharger would work if you used the correct head

 

sounds interesting for civics or bikes .. maybe.. but I woudnt
waste my time ...
And even if that electric SC could spin fast enough..
wouldnt it be loud ?

 

It takes a lot more than 5HP to run a blower. You may be able to spin it by hand, or with a drill, but that's nowhere near the speed it would need to spin to create boost, especially the instantaneous boost created by a crank driven setup.

 

did you read?

 

Damn it's amasing how many times we go over the same garbage..

If it is such a good idea.. where is Paxtons electric SC, or Vortech's electric SC, etc, etc... The lack of units from the top companies should be a big clue.. BW

 

???? where do you read to? I SAID IT WOULD WORK! BUT, useing the crank makes more sense. man read! I never said how well it would work. if you don't like to read you are in the wrong place

 

All right, I think we flogged this horse to the bone. The thread was started to ask about those electric superchargers that they sell on eBay. I think we all agree that those are junk, and a total waste of money.

At some point the conversation spun off into a theoretical discussion of using an electric motor to run a supercharger that was on par with a roots or centrifugal type blower driven off the crank. It makes for interesting discussion, but they don't exist except in imagination. They would be far too heavy, and very difficult to package in an engine compartment. This is why no manufacturer like Paxton, Vortech, ect offers them.

Could it be done? Probably, because if you're willing to throw enough money at something you can usually make it work, but I wouldn't hold my breath for the new Vortech R-trim E.

 

theres a guy close by here in miami who has setup an Eaton 112 to run off of battieres....

its on a Dodge Avenger and it puts out about 20PSI of boost.

It also consumed enough power to melt the lead posts of one of the batteries. He run 4 of them in parrallel for 48 volts..

its pretty slick / sick. Not my idea of a user friendly setup, however, I saw one of the batteries explode a few weeks ago. Not a pretty sight..

But the fact remains, He took a belt driven blower and turned it into an electric belt driven blower.. and it worked. it actually worked. theres a post on this board somewhere about it too...

 

I belive Mercedes is developing an Electric Superchager to work with 42V electrical systems.

 

Those 50$ electric blowers off of ebay are junk. My buddy tried one on his Dodge Omni. He was driving on the highway when out of no where he heard a snap and then BANG!!!. He quickly pulled over and poped the hood to see what was up and noticed that the turbo was red hot. After letting it cool he disconnected it and noticed that all but 1 fan blade was still attached. The other 2 were jamed in the throttle bodies butterfly. He used needle nose pliers and pulled them out of the TB, tossed thePOS on the side of the highway, got back into the car, started it up and it did start but he said it runs like crap now. Aparently some of the material from the break went into the intake and did some damage.

Electric supercharger = bad. If I see something that comes out by a major company that not only backs the product with a warranty but your vehicles motor as well...then I will try it. Until then, El-Supercharger = no!
