I think you would be better of running a 2 inch hose to your air conditioning duct work . same pressure but super cooled air......

I love the fact that fan isn't even variable speed... at 1000 rpm  the engine should be able to out suck the fan

So you're gonna do this when?

never.....

The supercharger has to be making pressure in your intake, while at the same time the engine is sucking out cubic feet of air every second.  So this electric blower has to be moving say about 10 cubic feet of air every second, and not just moving it, but also make positive pressure.

Superchargers put a load on an engine.  They more than make up for the power they draw, but they do draw a significant amount of power.  (I've read somewhere if I remember correctly that a top fuel dragster's supercharger draws 700 hp.)  So say if the top fuel dragster's making about 2000 hp, and you want to make say 500, you are going to be putting a fair amount of power into the supercharger.  Let's be conservative and say about 60 hp.

You can go to an online unit conversion site/tool and see that 60 hp is equivalent to about 45 kW.  Watts equal volts times current.  If we divide 45,000 W by 12 volts, we see that this supercharger would take, assuming equal efficiency compared to a belt driven one, 3,750 Amps.  You are going to need I'd say at least a half-dozen batteries, a bigger alternator most likely, and some series electric cable, for that much current.

This is why the electric superchargers are not what folks on the internet make them out to be.  To do the job requires an amount of power that is not practically delivered by electric power.

you make some valid point Main One check out Super Power Chargers, are they overstating is this possible.

I see no where on their site where they indicate flow rates versus pressure.  Look at this Garrett site as to how they represent the performance of one of their turbos:

The Super Power Charger site makes a great deal of rpm, but that is far from the total story.  They also make great claims about how well electric supercharging works versus belt-driven and turbocharging, and note that OEMs supercharge some vehicles.  If electric-driven supercharging works as well as they claim, how come we've never seen it on an OEM vehicle?

I would love for this to be practical, but I'm afraid this is internet snake oil.

Agreed, and not cheap snake oil either!
