Electric Supercharger??

I wonder how many suckers this guy's taken

Sounds reasonable to me. Not willing to spend my money on it though.

Double digit HP gains...... 0.1

I could put a 12v fan motor in for a lot less than $139.99!

Indy · May 5, 2005

I saw actual dyno runs with one of these and there was no gain at low rpm and a loss of power at higher rpm because of the restriction of the fan on the airflow.

LOL

This guy makes it seem like a belt driven SC, actually lowers your HP.

I wonder if I could fit my 26 inch box fan under the hood...........

I checked his feedback. First of all, he's hiding his item numbers, but some of his buyers have indentified their purchases as superchargers, and there are more than a few unhappy customers.

If you think that maybe 500 cfm has to come through the filter at top hp, I just can't imagine that "blower motor" keeping up, much less providing any increase over what would have happened with natural aspiration.

I'd be surprised if that thing has any more cfm than a bathroom vent fan, and that's way less than 500 cfm. That "blower motor" probably sounds like a bathroom vent fan too! It'd be embarassing to have that thing.

What a scam!

You almost have to give him credit, its a pretty good marketting ploy.

Sell something that looks like it could work to some people, throw in a decent air filter that probably has some gains associated with it. Added with the fact that most people think they feel gains after doing mods... even if the gains really are decreases in power. And sell it for a decent penny..

The way I look at is... if your dumb enough to buy it... its your own fault.

as for the 500 CFM.. yeah maybe, it might be able to move that much air.. but not at 5psi. We have delt with alot of these blowers for a project we were assigned... alot of times centrifugal blowers are only rated at 4psi... and thats a fairly large AC unit... much larger than anything like this. I highly doubt that could build more than 0.5psi

If you look at his pics, its on some ricer.

These things propbably sell like hotcakes to them. I mean if they are willing to buy a 25 hp sticker, they would be willing to buy this.

I got an old "Weedeater" brand leaf blower that I could make into one of those!

It still amazes me that ebay lets this sort of krap go on. Bleh.

MAD POWA FO SHIZZLE YO!!!

The theroy is viable but the application of it severly lacks. It would take a centrifical blower with a motor of several HP to even begin to make a difference but them it would over draw your electric system running it because it would take at least 8 to 10,000 watts of power to make a noticable difference which would be ruffly equal to what your starter draws when cranking engine. To give it a seriuos boost it would take two to 3 times that amount.

Just for a comparison, a roots type supercharger, like the Radix, takes about 50-100 hp just to drive it at about 6 lbs boost at max rpm.

This " Elec. supercharger" would need appx a 75 hp motor on it to supply enough volume and pressure.

Actually I think the a electric one could do it on about 30 to 50HP on a small block because of less drive loss and better efficency because it could be run at a fixed RPM with a waste gate to keep a constant pressure.
