How would they have enough torque to spin an impeller(?) at enough speed to produce boost. Doesn't compute.
Then again I've never laid eyes on one either.
It looks too small for a 4.0 six falcon donk.

This is actually used on marine engines, and is NOT suitable for car engines.

The piping is way too small and actually will inhibit the induction system as it can simply not blow enough air.

Don't even bother.

WTF!!

I got one on my car and it gave me a bit more top end power! Just becuase its electric dosen't mean it can't produce the same power levels as a engine driven one :)

The problem isnt that its electric, its the amount of electricity drawn and the design of the fan.

There are some electric supercharges out there that do work, but they require extra batteries to be fitted and usually cost more than mechanically driven superchargers. This is because you need an electric motor that produces several HP to be able to spin an impeller with enough speed for the airflow and pressure required.

The other problem is that these electric supercharges are axial fans, not centrifugal fans. Axial fans can flow alot, which is why you see 800cfm+ of airflow being quoted, BUT they are very very poor when there is backpressure on the fan. Centrifugal fans are used in real turbo's and supercharges because they do work with back pressure so can actaully generate boost.

So they dont work because
a) wrong fan design, they might be able to keep up with the airflow of an engine but wont be able to generate boost

and b) the electric motors are simply too small.

But i didnt have to really say that because its all been said in NUMEROUS threads before.
