Electric turbos myth busted...
The root problem here is that an electric motor is only about 50% efficient........ So, it would take a prohibitively heavy duty electrical system to power the bulky motor required.....by adding all that weight, you're at the point of diminishing returns AKA "shootin' yourself in the foot"
A supercharger impeller spins at 50,000rpms then compresses this air into its casing.A electric motor would need to have a large,heavy motor with specialized bearings and heavy duty fan blades in order to spin at those speeds.Believe me if it was possible to create a system that would work,Procharger,Vortec,etc would have already produced it a long time ago.
I know they are a joke, the only way you could see a gain is if your airflow really sucks, other than that they do nothing or block the airflow. I think it has a very good idea behind it, why didn't somebody come along and make a real one instead of a joke. They could do the same thing as a turbojet engine, air flows into the compressor fans and sends it to the combustion chamber. Also a centrifugal type supercharger, possibly even a positive displacement supercharger, could be ran with an electric motor, the motor could be then tuned to the maximum amount of boost the engine will take, or what you want, at varying rpm. All it has to do is overcome the extra weight added by an electric motor. The electric motor could take a load off the engine and boost all around efficiency, as long as the load would be greater than motor weight.
