Dyer864 Posted October 26, 2007 Share Posted October 26, 2007 Hi all ! been looking on ebay, and came across this,i know there was another similar crap gadget on there before, like for just £15.00 or something, but this seem's a bit steep in price of £135.00!! Does this item work on the same principal as that crappy one listed over amonth ago ! read the buyer's comment's and all are happy with product, but i suppose they would say that wouldn't they !! http://cgi.ebay.co.uk/Electric-supercharger-Turbo.TOYOTA-MR2-SUPRA_W0QQitemZ22016. :search: Link to comment Share on other sites More sharing options...

tooquicktostop Posted October 26, 2007 Share Posted October 26, 2007 I cant see the link but I will still wager its a piece of cr*p Link to comment Share on other sites More sharing options...
kieren1234 Posted October 26, 2007 Share Posted October 26, 2007 Yes mate, it is a piece of shite. Cant see the link but i know its one of them electric superchargers. All they are is an inductuction filter, with a 12v pc fan which you can blow harder than that can. Stay well clear, cheap tack that wont work.

kieren1234 Posted October 26, 2007 Share Posted October 26, 2007 And please tell me you weren't contemplating putting that on a supra???? Link to comment Share on other sites More sharing options...
Dyer864 Posted October 26, 2007 Author Share Posted October 26, 2007 Def not mate, just thought it was steep in price for that kind of crap !!, i'll try and sort link out cos it's not working for me now ! :blink: Link to comment Share on other sites More sharing options...

garethr Posted October 26, 2007 Share Posted October 26, 2007 If you look at how much power it takes to drive a real supercharger, and convert it to electrical units, you'll find that the performance gains will be negated by the weight of the generator that will be needed http://www.autospeed.com/cms/A_0237/article.html?popularArticle So, how much power does it take to drive an efficient supercharger like a screw type? The most efficient type of supercharger, flowing 265 cfm and developing a boost of 11.5 psi, takes 14.5kW to drive it. Figures aren't readily available for centrifugal blowers, but they'd be of a similar magnitude. So the best blower design (the same type that's used on the Mazda 800) takes about 14,500 watts to drive it on a modest-sized engine. This power is derived from the engine via a belt connecting the blower to the engine's crankshaft. But let's say that instead of using a belt-drive from the engine, we power the supercharger by using a 12 volt electric motor powered from the car battery. For an electric motor power of 14,500 watts, we'd need a current flow of about 1000 amps (14,500 watts divided by 13.8 volts = 1050 amps). So, to supply the current to drive an electric supercharger having the same airflow output as the most energy-efficient type currently available, it would take 1000 amps. To generate this much electrical power would require at least 8 heavy-duty alternators bolted to the engine. Furthermore, to handle this current, the wires connecting the battery to the supercharger would have to be enormously thick - perhaps brass or copper bars 10mm square would be needed. There is a working electric supercharger, but it's a bit more complex than the ones on eBay, and it needs at least four extra batteries: http://www.turbomagazine.com/tech/0406tur_knight_turbo_electric_supercharger/index.html Link to comment Share on other sites More sharing options...
kieren1234 Posted October 26, 2007 Share Posted October 26, 2007 And ALOT of room in the engine bay aswell Link to comment Share on other sites More sharing options...
Digsy Posted October 26, 2007 Share Posted October 26, 2007 It would probably make a nice generator if you wired it in reverse and let the engine suck the fan round Link to comment Share on other sites More sharing options...
