Superchargers don't have momentary drain, they are constant. Only turbochargers react to how hard you press the gas peddle and that's because they are driven by exhaust gases. I would imagine this thing will be like driving all day with your windscreen wipers on - taking the same amount of power.

With a well working generator, regulator and a fresh hi-po battery (or two!) you should be able to handle the momentarily increased drain by the supercharger. (Unless you always drive with the gas foot flat on the floor ;-) ) Just my thoughts.. Greetings! /Karl-Olov Sandin ------------------------------------------------------------------- Too much?
