Those are just bilge blowers and HVAC squirrel cage blowers, they are incapable of making measurable pressure on anything. They can't even keep up with the natural airflow of a 1.6L g@sser let alone move enough air to pressurize the intake of anything larger.

Amazingly enough, there are people stupid enough to pay $400 for those things. LINK

About 50 years ago my father bolted on an industrial electric supercharger to his Nash Rambler straight six. He lived in the Romulus area in Michigan and they used to drag race out at Willow Run. It took the top speed of the Nash to over 140 mph. That was how fast he was going when the convertible top ripped off. I don't know his 1/4 mile ets but he said that it would easily beat the stock V8 engined cars of the time.

A lot of technology has been tried and proven and then forgotten about and then rediscovered.

It wasn't forgotten about, it was replaced very early by superior technology (turbochargers).

You must mean a turbosupercharger. See how easy it is to forget?

Same thing, different name.

Yes, now that you have read the 1941 NACA report you understand that.

We'll just have to wait for an archivist to upload scans of electric supercharger documents from 50+ years ago so that it will be equally accessible. People hate to roam the stacks anymore and those with firsthand knowledge are quickly passing away.

Well in theory its a supercharger where the mechanical linkage has been replaced by an "electrical linkage". It probably work well with a seperate generator for the supercharger allthough it would probably result in a greater-to-boost ratio than a mechanical or pneumatic driving force aka super/turbo-charger. If you want instant boost i suggest a turbo with VNT OR maybe a supercharger with a Constant velocity transmission attached for a continous level of boost.
