I did a little research on this topic in a forum I know pretty well. They were really tough on the poor guy presenting it.

eRAM electric supercharger ( a brief description) & some responses to the many post - Pelican Parts Technical BBS

Long thread, I read the whole thing.

I've given up on the idea, looking for passive solutions now.

With that much power being used in the electric super chargers, why not just power the engine directly with them? Or would that be considered a dreaded evil hybrid?

I did this in my garage and I was drunk most of the time.

Surprise, surprise - I disproved this Kibort person's outlandish claims about his precious eRam, several years ago. That is nothing but a high-powered bilge fan.

You want to buy mine (I still have it), you can give me a reasonable offer for it.

I haven't posted enough to toss you the link but its a pretty fun read
Only 2? I think it was roadkill but they put 5 in the back of a hatchback! They had to have a pressure relief valve because there was so much pressure after 2 that the others would start.

I think they noticed a slight power gain, but for as much as they spent in leafblowers and fabbing it up you could almost buy a bargin bin turbo.

Legitimate electric blowers do exist however you are looking at at least a $2000 investment. A legitimate electric blower system will have its own battery or disconnect the battery from the cars electrical system while in use so as not to bog down the engine with the alternator. As far as economy goes though I have my doubts. This might pay if you had a diesel (as boost can increase efficiency in a diesel) in pure stop and go traffic with very long red lights but its unlikely.

The piper must be paid and using an electric blower you are taking out a loan so interest must be paid too. You borrow energy from the battery to create the boost, then you have to pay it back with the power sapped from the alternator. A direct drive blower or a turbo are more efficient as you do not have to pay the alternator efficiency tax.

BMW files patent for electric turbocharger | New and Used Car Reviews, Research & Automotive-Industry News & LeftLaneNews

Quote:
BMW has officially submitted plans for an electric turbo to the the German patent office, suggesting the technology could become a reality in the not-too-distant future. In fact, the next-generation M3 could arrive with the technology sometime in 2014.
An energy recovery system when it's off boost and no lag when it's on.

Funny video about ebay electric superchargers and leaf blowers. (Yes they actually hook up leaf blowers and it's hilarious)

While it's pretty obvious that the tiny electric fan wouldn't produce any boost, that was a somewhat stupid video. (smart in some ways, stupid in others)

I've always had issues with how Mighty Car Mods does testing, and when you do so few pulls and show power increasing in a linear way from the first run of the day till the last run of the day, then there's questions as to the condition of the car at the beginning of the test.... which should have been A-B-C-A... and should have included readings for manifold pressure.

Also, the blowers are supposed to all be put after the air filter... for obvious reasons. Failing that, they should have removed the air filter inside the can.
