Not that I think they are worth the money... but dyno tests have been done on the electric superchargers and they do work... just not quite as well as this company claims. I think they achieved something like a 6hp gain in the BEST case they tested. They never generated enough pressure to register 1psi of boost or anything like that but it was about the same effect as an open air setup in a moving vehicle.
So yes, they do work..... just nothing spectacular.... worth it? Probably not.
Whole different type for the ones your thinking of.You will loose HP from the added strain your alternator is putting on the engine trying to power it at high RPM's,which that snake oil will not be able to keep up and actually cause a reduction in flow also reducing HP.
No, I'm talking about these cheap bilge fan style "superchargers". Actually read an interesting article about them where they found some strange trends when running these. (wish I could recall who did the tests) Minimal dyno gains were noticed (2-6hp) but there were consistently slower times in any 0-60 or 1/4 mile test. They figured that it mimicked the minimal gains that a vehicle gets while it's being driven due to the incoming air. When the vehicle is sitting still on a dyno it was barely noticeable in the numbers. As soon as the vehicle was actually moving the naturally incoming air surpassed the "supercharger" and it became an impedance to airflow. It seems that the only thing it can successfully do is minimally increase dyno numbers on small engines.
