A guy I used to work with bought one of those 'electric superchargers'...said it worked awesome!!! And he showed me...over and over, 'cause it was so awesome!
I timed him over a couple of 1/4-mile-ish runs with the unit out of the vehicle, then with it installed again. Of course, you know what the results were...no speed increase at all...
Still didn't convince him though... So I did the 'manometer' thing and showed him exactly how much pressure increase he was getting...slim and none. He still swears by it...(idiot)...
And as far as I know...those wire things on eBay. If I'm right, there's 2 versions... The one you mentioned for the simulated cold air, and the other one supposedly puts a parallel resistance inline with the TPS to trip the computer into open-loop mode at less of a throttle angle than normal.
Any other good ones?
