Boyesen Power Wing & Power X-Wing

[stepthrutuner]

Have you guys ever heard of these? It's supposed to add a bit of mid range torque and improve throttle response very noticeably. They are made for both slide and butterfly carburetors and are available for a number of applications including Harleys and thumper dirt bikes. The ideal is to reduce the turbulence, especially at slide openings up to half throttle.

Although they don't make them for our small carbs, it doesn't look like it would be too hard to fabricate one and try it out.

At least they make killer reed petals we can use.

Never heard of the Power Wing or Power X-Wing before now. It reminds me of the Tornado... but just the opposite. The Tornado claims to make power by swirling the airflow and this one claims to make power by straightening the airflow. My first thought upon seeing the Power Wing was that it looks like the butterfly on the 4T carbs that I wished I could get rid of, but it does appear to be much thinner and more smooth. The butterfly is also more of the shape of an airfoil when it's worked over a bit, this looks like it's just flat other than the hump in the center.

That is one crazy price though... $130. I guess it shows how having a good idea pays off. I can't imagine cost or production would be much for a small amount of sheet metal. Even if they did make 'em for our carbs, I think I'd try to make one first

The Tornado was a useless gimmick IMO. These things actually make sense in theory.... i.e, less turbulence, more air velocity, better vacuum signal, improved atomization, improved case filling and flow past intake valves.

No doubt, the Tornado didn't do much at all. I owned one when I was 17. It made the intake louder and otherwise nothing really noticeable for me. I removed it and gave it to a friend that said it helped.

Off topic, but I understand it's not really scooter riding weather up there roundabouts Preston.... rain and wind and all.

Oh sure. It's cold, raining, and pretty strong winds.
