i saw that video on street fire... it was BS! the leaf blower was plug'd into the WALL! if they power'd it off the car, the HP gains would barely be there if at all.

also from that same test, it showed that there was an increase in power down low, but at high RPM, it killed power. these fans just cant supply the volume of air needed at high RPM.

i have seen an heard about powering one of these off a sperate battery, and recharging it later, cut when ever the blower is off it blocks the intake and kills power/MPG. if there was anything in electric SC, the auto industry would have used it in a prototype car alread. hell GM had a turbojet powered car in the 70's! and mazda's crazy rotory! there are very few cheep mods. many of the cheep mods are only cheep cause it either doesnt work, or it involves you modifying/ building it yourself.

bottom line this is one of the too good to be true mods.
