looking at that site and seeing talk about extra batteries and 6-10 minutes charges for a 1/4 run it seems kinda wasteful...And if its not running all the time it must restrict airflow when off...not to mention all the cable that has to be laid down for extra batteries. And then locating them in a safe, non-mobile spot (i.e batteries located in trunk unsecured
). oh and don't forget that you need to upgraded to a 200+ alternater. So till your said and done you'll probably have a bigger pita and larger bill then a normal supercharger.
thats just my thoughts though
