I just found this site

Anyone know anything about them?

$100 for 20-30 hp sounds like good bang for buck

 

This has been discussed hundreds of times. It is complete BS and starves your engine of air. If you search you'll come up with all the hits for this crap.

 

ok thanks mate

 

i didn't actually think this was a serious thread... nothing surprises me any more

 

THIS is the only design that ever worked, but it's big and heavy and you have to add a lot of charging capacity to your car.

 

Yeah I guess if they did work I would have heard a lot more about them here.

 

The most efficient belt driven supercharger consumes 15-25 HP providing 5 psi of boost on a smaller displacement engine.

An electric motor driven supercharger could do the same thing just that it needs 1kw per HP..............thats 80 amperes @ 12volts per HP.

Running 15 starters simultaneously.
