I read a few forums and discussions about this and from what I can tell, this would be no greater benefit than a good air filter\intake. The problem is that they cannot increase the amount of pressure going into the intake ( most say one pound ). If done correctly (I heard the ERam was ok but is of cheap construction) mabe it could add 10-15 Hp??????? The other solutions with mutiple batteries were for regular superchargers that were powered by electric motors instead of fan belts.

In my opinion, If I could pick up another cheap 10-15 horsepower (about $100 - $200) in addition to whatever I get from intake and exhaust, it would seem like a worth while proposition (until I could save up for the real thing!!!)

When any of you guys find one, let me know..........

Until then, I'm gonna save up for a Superchrger
