    electric supercharger

    has anyone tried these new 5 - 8 psi electric superchargers on say an fx140 or anything else?
    the benefit being you can switch off when you want to potter about and save fuel or full on power on a switch. the mr1 engine apparently will accept 5psi boost without changing compression (fact?) therefore giving approx 175hp with simple addition. probably need a bigger battery due to energy consumption above the charge rate.

    All the electric superchargers I have seen have all been scams. It would take a pretty good size electric motor to move more air than these engines can suck and thats what it takes to make boost. Would also take alot f battery to turn such motor. Do you have a link to the one you are refering to?

    elec sc

    i have lost my original links now but just found this one http://www.electricsupercharger.net/faq.php it says up to 8psi but when i read into it before it did drink some power, something like 700w or so (more than the charge rate) hence why i suggest a larger battery and not running sc continually.

    You'd be better off taking 3 or 4 normal bilge fans (rated for marine use) install extra air intakes, and "pressurizing" your hull with fresh air, and a spare battery.

    what about the extra fuel that would be required if it actually worked?

    not sure it would be easy to pressurise the hull with extra intakes and keep it pressurised. you would have to load the pressure up in the hull each time, as opposed to electric sc where you can turn it on at will.
    yes you would probably up the injectors 1 size to accomodate for the extra boost but nothing major or could add an RRFPR to bring fuel pressure up with when on boost.
    i still think it can work with these small pressures just to make it a bit more lively for low cost. it is just a question of how good these elec sc are or just a load of marketing hype, do they actually make 5-8psi?

    if you stick your hand in front of your stock f/a while its at WOT, you will feel that it is sucking a lot more than 5 psi.. waste of battery i think
