well the biturbo is kinda falling apart, had the cant start to fall off, so i used an amp can and 2 hose clamps to "fix" it. works and looks kinda neat. id really like to get some launch speed, it doesnt do shit till it hits second/20 mph. but im a big guy and want to keep the top end if not increase it some. i know sprockets do weird thing (increase top, decrease take off & vice versa). ive got a 22 rear i think, so blah.
thanks steve!
