I have seen these electric superchargers before but not liike this one. My question is is it possible to mak eone of these and how mch would it cost cause i just wanna try it out.

is that really all they produce is 1 psi?!? if thats the case, then i would rather buy a circular fan and stuff it in the throttle body. then just switch it on and off when im getting bored driving on the freeway.

Thi is part of a post on the impreza forum. cant find the post but here is part of an email I sent to a friend
the tornado produces the same amount of hp.....when tested actually gave like 3 high end HP......but lost like 9 hp through out almost......so an avg gain of -6...that sound like fun..
does this mean that if ricers have this, they can justify that "electronic" BOV?.......you know the one that gives the "look and sound of a real BOV
I was thinking a better idea than the electric turbo is maybe using a leaf blower
I'm the person who tried the e-ram electric supercharger on my 2000RS. My install can be viewed here: http://users2.ev1.net/~subaru/E-Ram_installation.htm
After having it installed for a few months, I removed it. It just didn't perform as I hoped. It is my humble opinion it made MAYBE 8-10HP, at the most. As far as the drag on the alternator: it is simple enough to make an alternator cut-out so it has to run off the battery only while it is activated. The battery can supply 900AMPS for a while with no problem. The problem with the e-ram is that it needs to have a 12 bladed fan and dual brushless motors to be more effective. That would cost like $1000 to make, which is half the cost of a stage one turbo kit. Not worth it in my opinion...
Oh and by the way those electronic turbos are really Bilge fans. They suck out stale humid air from the engine compartment in a boat.

Uhm. Yeah....
"Spinning at 150 CFM at 8000 RPM!"
Yeah... Our cars are rated to have a max airflow of somewhere around 450 CFM. The engine itself creates that at near-redline levels. WTF is the point of having an electric motor that flows 150 CFM creating turbulence inside the intake system?
Please don't assume that the 150 CFM the blower makes is added on top of the ~450 CFM the engine is creating. That blower simply being there is a hindrance. It will actually reduce the airflow slightly. The only thing this can do for you, is slightly improve idle. Are you going to pay that amount of money to improve your idle?!?!
...And if you wonder how it can impede airflow, just think of that little fan at max speed while you're running the car on the freeway, full throttle, and near redline: the engine is trying to draw in air (vacuum from pistons moving up and down) as fast as it can be allowed (size of throttle body, intake piping, intake manifold, head ports, valve sizes)--having that little fan running at 8000 creates a small wall that the air has to flow against. Remember, the engine is trying to suck in close to 450 CFM while that little motor is pushing 150. The engine is actually surpassing the electric motor's capabilities.
Someone needs to shoot everyone that comes up and has already come up with these electric "superchargers."
You could spend a thousand dollars on a mechanical supercharger and recieve far better results.
I swear... The logic that these people have whom buy these electric superchargers eludes me.
Everytime I hear about someone putting a leaf blower or electric supercharger on their engine, and then others are like "wow! I need to do that, too!" I always get the picture of blind people leading more blind people over a freakin' cliff.
