Just because someone clames their electric supercharger/turbo produces XXX cfm does not mean that the setup they are selling can produce any boost what so ever.

More often than not they are selling a boat engine bay vent fan that will do nothing other than put your engine at risk.

Others sell a motor mated to a squirril cage blower that are good at moving a lot of air however, they are not capable of producing any pressure.

The vast majority of these socalled electric turbos/superchargers are snake oil just like the tornado and the pill that is supposed to provide you with increased milage.

There are no free power gimmics that work, the only person they benifit is  the seller.

Here is a link to someone who has spent a lot of time and reaserch on the subject of an electric supercharger as you can see it is a lot more than a squirril cage fan.

Don't fall for a scam if it sounds too good to be true it probably isn't.
