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.

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.

Why when a turbo does the same job more efficiently?

'78 300D, OM617.912: 4spd manual, TB03 at 10PSI, 26*BTDC, DV's turned, HVAC, emissions system removed, e-fan, short ram, 3" downpipe to straight exhaust, W126 Bendix brakes, MR2 Spyder seats. 2890lbs

Packaging, location and operation independent of the engine are about it.

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.

You would be better off with a gas powered leaf blower!!!! I knew a kit who put one on a Honda and made 30psi and set the internals of his engine on FIRE he took off the oil cap and flames shot out!!! LOL

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.

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..
