sounds cool .like a blower on demand. i really thing it would work crappy. it would be a lot of work to find and make a pulley set up and aE clutch that could take and drive a 3 inch belt and take the shock when in engaged ?? at any speed and deal with the blower mass and if the blower is rotors are lined then it would suck big time to get any air / fuel .i would think it would be very unresponsive with the drive belt not engaged . so i would think it is a mad max only thing
