think of the motor actuation on the blade pitch, analogus to a variable pitch prop on an air plane. what it does is make the impeller more efficient at a given speed. thrust or(pressure and air flow) out of a fan is related to 3 things and 3 things only. diameter, eff, and HP. what they are doing is changing the efficiency dynamically. some of these most popular designs miss a key point. you really dont want a compressor working at idle. at idle, the throttle body is a big pressure drop. (ie throttle means choke) so , why would you want pressure at idle, when it will just be bled off by a relief valve? some of these designs and concepts seem to be half baked. turbodyne had a pretty good electric supercharger (radial blower) but their problem was current draw and it had to be working more than just WOT to keep the power transitions smooth.
I think the best design would be a high end design of my patent of the axial flow electricsupercharger. something where 3-5psi is generated out of an axial fan.

ELECTRIC TURBOCHARGER PROMISES MORE PRECISECONTROL
Ishikawajima-Harima Heavy Industries Co. is developing what it touts as the industry'sfirst motorized turbocharger, reports the Nikkei Business Daily. IHHI says the system willenable more precise control, eliminate turbo lag and help boost fuel economy.With a conventional mechanical turbocharger, exhaust gas spins a turbine blade onthe exhaust side of the engine to create enough rotational force to spin another blade onthe intake side, thereby increasing airflow into the engine. The process typically doesn’tstart until the engine has reached at least 2,000 rpm. The electric unit uses a motor to adjust the angle of the exhaust turbine blade and asecond motor to help rotate the axle connecting the exhaust blade with another blade. Theconfiguration can supply compressed air to cylinders even when the engine is idling, thesupplier says. It hopes to have a production-ready unit validated in three to five years.

Mark,
I am a systems engineer in the aerospace industry and we use some fancy fans but they all have trouble building pressure. 1-2 psi is the highest I have seen but I guess if you want more then you would have to do multiply stages like adding another fan in series, where it takes the pressure up from the first fan and bumps it up too. The increase of the second is about 75% of the first.

You're all wasting your time, you as well Kibort!!! 
You have to have a gas powered supercharger...and..uh...yup, a dash of nitrous

Ive seen some not so fancy fans, and they build pressure from 35,000feet to 10,000 using axial flow fans driven by a single electric motor and two fans in series. (very similar to the super eRAM which is a stacked dual eRAM set up)
second, depending on the stators, first fans pressure and second fans rotor pitch and other factors, you can see that dual axial fan compressors driven by individual motors can double fan static pressure and depending on the air flow and pressure, can double it at some moderate flow rates.
I need some fancy fans! have any i could take a look at??
we do have a new model that uses a custom purpose built fan enclosure and impeller.

that was really funny! kind of the same idea . had no idea where the NOS was coming in until the last video clip. just spraying it in the intake of the blower, pretty cool (no pun)
what was that 177 hp to 187 to 222 with the nos shot too? impressive
we have a metal impeller now, so we could do that too!

Tony,
Respectfully we are not all interested in Turbos, Super chargers or NOS. If you add fans you get an increase and that is a positive for the amount of money you spend. I know it is only 10-20 hp but it helps with the other things we can do. It is like saying if a woman does not have double D's she's no good. Well a good, clean BB would be nice especially if she's paying.
Mark,
For me to get fans out of here would be impossible and the smallest ID is 6", about $3000. We do use 3" low CFM ones to keep pilot displays cool but we track every part and I can't get any out even if they are damaged. Rotron or Dynamic air is the manufactors.

Good luck with testing four units.

Carl,
I know Rotron well. they are cooling fans which really have no design for creating pressure, just flow. the eRAM, as you know, is several orders of magnatude more pressure and flow out of a 3.5" diameter. thats key. Rotron, OM , etc all have 500 to 750cfm, relatively high pressure axial flow fans, but are usually 7" diameter or more. (and some use dual stage) . these fans are usually 100-200watts as welll. with the eRAM taking 800watts+ and having over 1000cfm out of a 3.5" diameter , you can see the pressure potential is much greater.
thanks for the thought of getting me some of the "trick" stuff though!

Guys,
I was sent over to your forum from the 930 forum because I had the nerve to bring this subject up! Talk about preconceived opinions. No openess to even discuss the subject. The same false science and bad data. Mike was nice enough to e-mail me about his product. I was interested in reducing turbo lag and that was all I wanted from the unit. Mike explained how it would help in reducing lag and for $300 it seems like it would be worth it unless the addons required add up to big $. I told Mike I would try one if I can get a money back gaurantee. It looks like simple science to me but I am aware of how cone filters/cool air sys can actually lose HP. You have to try it on your own car to decide if it works or not.

Want more power? How about an electric turbocharger?!

Well I tried to create this as a new thread but it was moved into here even though it isn't really about using the turbocharger. It's comedic fun.
