Electric Supercharger conv? Options

Anyone remember the Super Charger kit that Phil was putting together??

I have all the bits that he assemembled and his notes, and am trying to figure out how to make this system work.

I don't personally believe you can make 5 psi with a electric charger at the volume you will need for a 2.0 liter motor. If you have to add additional batteries and alternator supply the additional weight and power drain will offset the small boost it will give.
I've been wrong a couple of times in my life but not about automotive stuff this could be a first.
To make HP out of a specific size motor it will need a specific amount of air. I don't know the formula but a lot of people do. I know that 300 hp on a sbc needs about 500 cfm so try to make your blower make cfm and see what you can get.
A 2.0 wrx runs on about 12 psi I think. They make about 220 hp. I don't know if anyone has published the cfm. For example my sons sti is making 25 psi with a 30r turbo and making about 375 hp at the awd wheels. He is probably getting 8 or 900 cfm to the motor. There are some good books on pressurizing motors. Before you spend very much money I would buy a book.
There is a vw shop that turbos vw motors and they might know the cfm requirements.
A belt driven alternator that will supply enough amps to drive a electric blower will have more hp drain by far than a turbo, thats why you see so many turbos.
