Electric "super" charger

Saw video a few years back.of a kid that hooked up a leaf blower to his intake
Same idea and a lot.cheaper. I have no idea if it really worked or not.

That would be a negative ghost rider..... no such animal. But they will take your money.

There was an episode of Roadkill where they actually hooked up several leaf blowers to an intake. Just doesn't work.

I've been following electric superchargers for several years. The typical EBay offering is usually nothing more than a bilge blower, aka a simple fan, and is not capable of generating any boost.
Some automobile manufacturers are now developing electric superchargers to augment conventional turbochargers to reduce turbolag and maintain usable boost at low rpms.
A couple of individuals have been experiementing with electric superchargers for years. See this thread - Hybrid Turbos?
I'd originally thought about trying one of Robftss' electric superchargers on my Slingshot, but by the time I buy the developers kit and try to get a tune from @MEFIburn, the cost is about the same as a Hahn Stage 1 Turbo w/o muffler.

And not very well

The problem with the "true" low psi electric supercharger is the current needed to run them. Everything comes at a cost. You would have so much draw on you engine running alternators to generate the current needed to run even the smallest blowers. It's just not there yet. And may not get there in our lifetime.

Remember "Dreamaway" being hawked years ago for weight loss?

That's the advantage the systems from Robftss have over Thomas Knight's offerings. Robftss has developed a motor controller/AGM battery charger to allow the two batteries dedicated to the electric supercharger to rapidly recharge from the main alternator/battery setup. It is supposedly designed to support frequent/non-continuous operation of the electric supercharger in a typical street environment unlike racing use where the electric supercharger cannot meet the higher usage. Mr. Knight leaves the battery side of the operation up to the individual customer and doesn't seem to offer an integrated electronic controller. I think the current state the art for these electric superchargers is still in the realm of the tinkerer/experimenter and not necessarily ready for general use.
Neat idea if they can ever implement it cheaply enough.
