Hi, I have been reading up recently on electric superchargers and have heard that they do not make power on cars, but what about on small engines such as my standard gx240, do any of you think that it would make a significant increase?

Can you post pics of these things

An electric supercharger designed for a multi-cylinder automobile engine will not operate a single cylinder 240cc utility engine.
It's questionable that they work at all.

Just kartin' around....
I talked to this guy in Australia, who is selling electronic turbo kits for small engines, last week. I think they're like $75 (us)... So I asked him if they really work?
What kind of power increase should I expect?
Do you get complaints?
Do you get returns....
His answers.....
I'm not sure, but people tell me they work.
I have no idea on the power increase. There is no info available to prove or disprove they work.
I get a few complaints....
I get a few returns....
Basically, from a guy who sells them, don't buy it....isn't proven to work and there is no proof of power increase.
Even with its 10,000 rpm fan speed, I don't see it stuffing more air into my engine, giving me a boost in power. If it was REALLY that simple, they would have been out in the market way back in Russ' hay days..... China would have a cheap clone copy already set up for the Predator engines..... I mean think about it. At $75 retail, china probably makes it for $6...... Or less..... So if it worked,you see them all over the place. If it was really worth it, and feasible, I think Briggs and or Honda would have one on the market. ESPECIALLY Honda......

Unless a custom built electric supercharger made from a Old Turbo, anything else won't work like the plastic ones they try to sell

With all the extra from a good home made turbo, Where would you get the extra fuel.
Easier to buy a bigger engine.

Here is one of the kits:

That's Exactly who I was talking about. Even the seller doesn't believe it......

yep thats not going to build any boost whatso ever

now something like this would definitely work

I think you underestimate the needed motorpower to get a decent blower...
OR maybe I underestimate the power of that tiny RC motor... who knows.
but "definitely"... I doubt

i have motors from power wheels in that size that run 11000 rpm

The real test would be to put a boost gauge on it. Or a slack tube.
rpm is not the problem.. my DVD Drive motor runs at max 35000 rpm too...
the question is.. will it under load?!
And the load on the turbine blades is substantial, otherwise the whole turbo system would be pointless, right?!
I could guarantee that neither, my DVD drive nor your powerwheel motor will have any noteworthy positive effect.
I'll be honest with you, I have NO idea how to calculate the power of an air turbine motor correctly, fluid dynamics is a huge PITA to deal with for untrained folk like me;
Anyways...
I think you'd be better off driving that turbine directly from the output shaft at a nice ratio instead of whatever electric motor.

No, no it wouldn't. If an electric motor was efficient at running a turbo, AND could actually make a positive effect on the hp out put of a gas engine, general motors would have them on every vehicle they make. If they worked/could work, it would be FAR cheaper to make them than the exhaust driven type. Not to mention, it would be far simpler to set one up and maintain it, over an exhaust driven type. No plumbing oil lines to the turbo bearings. Just easier all the way around. And cheaper....
BUT they don't/won't work..... So you don't see them on any production cars. If the "big 3" ain't putting them in their sports cars, then that should tell you something...they don't work and any one who tells you they do , is just full of pookey.....
IF I had a small engine dynometer, I'd buy that electric kit, just to PROVE it doesn't work....... Without a dynometer, know one will ever know......
Realistically, I don't see a small electric motor having the torque needed to force enough air into my engine, to make a difference. And like hybridyne said, I bet it leaks air......
Moral of the story...... Save your money......
Uh Jim, don't go there...
I can tell you how to build one, but let's just assume I don't
I mean where's the point in spending money on scam to prove it's scam?
Scammer got his money and is happy.. you spend your money and know as much as you did before...
If anyone's -how do I avoid saying dumb here??- uhm.....inexperienced enough to trust such offers, so shall be it.
All we can do is warn them, we did... job done
