    How can an electric fan do anything more then slightly improve LOW end torque, and thats if its fitted correctly, with i dunno a second air filter to reduce drag.


    But on the Flip side,
    Does anyone have experince of a electric model air plane motors,
    they're quite good now, with brushless motors for high RPM & longevity.

    i was contemplating this MOD, for boredom, even bought a model stunt plane to crash and salvage. but the airplane model shop cant give me the type of propeller/impeller i want. with the standard propeller it moved more air then a household fan on power 3(full power).
    but i wasnt comfortable that a plastic propeller wouldnt break, and go in my engine.

    So thats another idea catching dust...
    Probably best mate, nothing wrong with trying new ways of doing things tho, i'm all for that, long as they actually work...

    These electric turbos/superchargers are rubbish chances are they will actually impede airflow anything above a third up the rev range, but the theory and potential is there, just trying to move enough air (commonly measued in cubic feet (CFM)) with an electrical motor driven impeller is not an easy task, it would have to spin the same as a normal turbo (somewhere near 130K RPM, please corrrect me if i'm wrong) and that isn't going to happen without a gearbox and a powerful motor that will drain ALOT of power, on top of that its got to actually force the air into the engine and with current technology makes it more hassle than its worth), thats how i understand it anyway.

    FYI

    a standard subaru turbo moves 360CFM at 14.7PSI

    a toro ultra (leaf)blower moves 385CFM

    alot of the electric turbo kits offer 250CFM which sounds good yeah... not really, that measurement is unrestricted in one side out the other, put that same fan in a situation like the subaru where it needs to push against 14.7PSI of pressure chances are the fan will leak boost and loose RPM and only move what the restricted flow of the intake pull past that cheap plastic waste of money

    They are my 2 cents, but i used to drive a peugeot, so feel free to ignore me

    Dont superchargers require 5-10% of the engines 'crank?' HP to wind them up? I could never see electric S/C working.

    The "hair-dryer" superchargers are only slightly effective on pit-bikes or other small (80-140cc) motorbikes. Even then its debatable.

    So in theory they work but don't give enough airflow.
    I like the model aeroplane motor idea.

    they add about 500bhp pal, nearly as much HP as my stickers add on my car
