Dude, now that I have thought about it, it just might work! I think someone should try it, and fill us in on the results. If it works, that would be awesome! If not, oh well. Yeah, I have seen some pretty powerful electric motors too. It looks to have the cylindrical fin setup, which moves quite a bit of air for its size. I bet if the fins were pitched right, this thing could actually work.

ok, heres what we do. everyone donate to the cause and buy one. I'll put it on my bike and see if it works. if it works I'll give everyone their money back, but if it doesn;t then we;re all out alittle cash.

The supercharger on a carbeurated engine is placed below the carb to more effectively atomize the fuel for a more consistent burn. Really important, especially when force-feeding air into your engine. If one cylinder is producing significantly more power than another, you can get all kinds of crazy vibrations and even bent valves, crankshafts, or cams, not to mention thrown pistons. Fuel injection atomizes fuel much more effectly than carbeurators because the fuel is pressurized in the fuel injection system, more so than in a carbeurator.

However, there are some superchargers that can sit on top of the carbeurator. With this kind of setup, you have to either purchase a "flow through" carb, or modify your existing carb because carbs were designed to work at atmospheric pressure. In order to convert your standart carb to flow through, you would need to mill the choke horn, seal the choke rod hole, and install upgraded floats in the bowls. Basically, you have to seal the entire carburator to upgrade to "flow through". However, running at 3 psi max, these upgrades are probably negligable, as is a fuel pump upgrade. 1psi added boost = 1psi additional fuel pressure required. 3 psi max is not that big a deal.

sooooooooooooooooooooooooooooooo.....
will it work or not?

[jnande4176]

Not sure. It claims 3psi max, so theorhetically it would work. You should feel some increase in power running 3psi of boost, especially on a bike.

According to KevinC (who I trust completely), it takes 5000W of power to make it even remotely effective.

Sounds about right.  Didn't want to go outside to find my books on turbine theory, so I hit the "easy" button and opened up Machinery's Handbook.  The table I have here "Horsepower required to Compress One Cubic Foot of Free Air per Minute (Isothermally and Adiabatically) from Atmospheric Pressure (14.7 PSI) to Various Gage Pressures -Single Stage Compression  (Initial air temperature 60F- Jacket cooling not considered)" shows .050 HP per CFM at 15 PSI Adiabatic.

Assuming the GS consumes about 500cc x 5,500 = 2,750,000 cubic centimeters of air per minute.  2,750,000 cubic centimeters per minute = 97.1 CFM.

.050 x 97.1 = 4.9 HP

I seem to recall that most turbos operate at about 65% efficiency.  (Combined inefficiency of the turbine and compressor.)  For an electrically driven compressor this is probably a little low, but I like worst cases. 

100 / 65 = 1.54

1.54 x 4.9 = 7.5 HP.

7.5 x 746 = 5.6 kW.

It's not a question of whether an electric motor driven centrifugal compressor is capable of the work, it's a question of whether the GS can supply the power to run it.  The answer is HELL NO!

so ur saying that it might work on a bigger bike?
