Hate to do it, but I agree with motormike, if it was that simple we all would have 1$ computer fans on our scooter intakes. The fan and motor required for that to even come close to making something like that work would prob be so heavy it would be impractical. And the physics for that don't add up. The motor is only gonna take as much air as it can suck in. The fan would have to compress the air more than the velocity and cfm than it takes in naturally and that little fan that barley flows enough to cool a video card CPU won't blow out a candle. You get an "A" for creativity and an "A" for effort though
and don't stop comming up with new ideas, that's how the best inventions are created, keep up the good work

Electric superchargers are very practical and surprisingly light. We've installed them on Yamaha 4-strokes. Yes, there is electrical draw but the factory electrical system will handle it for a few drags when the battery is full.
I've heard of but not seen them installed on the Nissan 350z.
Hey I learned somthin new thumbs up

Superchargers and turbos compress air, fans just push air. All this mod will do is drain your battery.

Two strokes can be turbo charged.......just not with a CPU fan
We have discussed this before. Check it out.

They go through all the trouble of turboing the motor and don't put EFI on it?!
Is it possible to carbuerate a turbo'd intake that effectively? I would think you would end up running rich during turbolag compounding the effect (not to mention a pressure spike would make you lean).

Little food for thought.
Assuming 100% VE, your scooter sucks down 49cc per stroke. Each stroke is a power stroke. 8000rpm is your peak power rpm (just assume).
392,000 cm^3/min
13.8 CFM. @ 14.7 psia.
This means you need to push 13.8CFM to meet the demand of the engine.

This random fan is 8.2m^3/hr @ 1.78mmH2O
Or 4.83CFM @ 14.707psia.
Not even enough to meet the demand of air flow and not worth calculating the CFM actual at static pressure.
However, your little supercharge looks good! look at one of those cheap electric ones on ebay for cars and you might be onto something fun!

They turbo bugs all the time using carburated systems and they haul *

This setup works because the carb is
before the turbo.
A well tuned carb is just as good as any EFI.

Yeah it makes sense when I actually think about it lol. Normally all my thoughts about turbos are in terms of direct injection diesels.

My neighbors Ski Doo is turbocharged with a kit from these guys.

I did something along these lines in 2008 with a dodge d50 2wd pickup I bought for 200.00 bucks. I used a craftsman electric leaf blower and a 750 watt inverter wired to a light switch on the dash. My local dyno shop tested it for free because it was so odd. It lost 1.2 hp at its peak, do to leaning out. If I would have up the jetting it would have increased power. I never went further than that, I was just curious what would happen. I also had to remove some extra stuff from the engine to prevent "boost leak". I am positive it did not create even 1 psi of boost, but it did add some.
