I'm not an engineer, but was thinking if it was possible to make a blower cheaply by using a bonner that would sit on top of your carb with a small inpeller mounted on a shaft that would be wired directly to your engine so the impeller would spin faster as your RPM's went up. In reality all a blower is really a air machine thats sucks in more air for better cumbustion. Would something like this work for small HP gains?
