They don't mention watts or amps anywhere in that article (for good reason). In a 12V system that would take 100-400amps of power to actually work. Thats why others have tried it using 24v, 48v and 72v systems. At best, it would be intermittently usable for ~10 seconds at a time but the actual use time would be based around the battery capacity. Alternator output wouldn't matter at all since having it supply the amperage would be counterproductive and inefficient.
99.99999% of "electric superchargers" are nothing more than bilge blowers and HVAC fans that do absolutely nothing but make scammers rich.

They exist and are well known to true turbo builders like Holset and Garrett. For it to actually work though, it takes several kilowatts of electrical power.

Packaging, location and operation independent of the engine are about it.
(09-22-2009, 02:52 PM)kamel Why when a turbo does the same job more efficiently?
The only job for an electric supercharger like this is to get the turbo out of bed early.
They work for a few seconds, then suck your alternator to death for the next minute or so.

I've thought about that. Get a small ~150cc engine to power a blower in the trunk and have a wastegate actuator on the throttle to automatically maintain constant boost.
(09-23-2009, 05:11 AM)Kozuka I'm sorry but the only way is to have a gas turbine engine with a shaft comming off the turbine spinning the compressor side of a turbo feeding the engine constant 80psi and fuel consumption is measured in GPM. But man no lag and full power..
AKA Hyperbar.

With a username like Tantank, you should know.
Quote:The "hyperbar" system integrates a Turbomeca TM 307B gas turbine in the engine, acting both as a turbocharger and an APU giving auxiliary power to all systems when the main engine is shut down.
