Back in high school (in the 60's) I can remember guys putting funnel shaped objects on their carbs and pointing them forward, claiming that at speed the air would be funneled and condensed so you would get a sort of ram air effect. Thinking back on it, that would seem to make them run leaner and might improve power a little at higher speed, but the idea of pointing an air filter into the air when you're blocking the front of the air cleaner, then "bending" the air through a 90 degree intake doesn't sound like a great idea.
I've seen similar systems to this on Harleys, but have no idea how effective they are.
