eletric supercharger

i keep seeing these eletric superchargers on ebay. r they for real or are they crap?

They are worthless..you can not make your car faster by forcing air into it..you need to compress the air for a difference so thats why turbos and superchargers are high dollar and those are only like 100-200

garbage, straight rip off, scam, whatever you want to call it. just dont buy that shit.

you can make your car faster by forcing air into it, but blowing air through a little fan is not forcing, forcing=compressing, dense air is more combustable.

just wait til hypsi87 or 89IROC&RS chimes in.

complete and uttter waste of money, the reason is that they do not compress the air as was pointed out by superchargedcav, so the air pressure never rises above 1 atm, when the valves close the air stops moving, and dosnt force any air into the engine that wasnt already going to be pulled in anyway. big ol ripoff.

You get what you pay for.
