well the electric turbo/supercharger thing is made up of a $45 blower motor and fan for some chevy truck the fans about 5.5" in diameter and i used pcv pipe for the inlet and outlets and a 5 gallon bucket has the main housing, because thats the biggest sturdy cylnder i could find that was cheap and easy to cut. I took the basic design of the electic turbochargers on ebay and basically just up sized the power by like 20x...the only thing is its like 11 inches wide and 5 inches deep...but i hooked it up to a battery at my work(advanced auto parts) and it blew hard...really hard...everybody there was impressed...i got to bring it into my school to ask my physics and engineer teachers a few question on how to better the design and get maximum air flow....If i can find some way to get accurate #'s i'll post...everybody i talked to about electric turbos was yea concept is good but the power isnt there...so i went and got the power i think it draws 30ish amps maybe more....i have only been working on it for about a week and jus now testing it....
