Has anyone heard of or have experience with these? http://www.boyesen.com/power-x-wing-9.html | ||

Seems a bit gimmicky to me | ||

I want to see the dyno sheet. | ||

I would also like to see the dyno sheet...the sportster crowd gives awesome reviews....Boyesen is a pretty reputable company....maybe it does help? They do say "Unconditionally guaranteed or your money back." | ||

Products they first come out with were good. I run the reeds in wifes kdx and my husky 250. More life than stock reeds for the 2 strokes. I know nothing of these wings. So many things out there are created with some science behind it and are marketed to the masses. Most motors never get built all at same time for a matched combination so one doesnt need these extras. | ||

It would be interesting to know what the Buell design and engineering team would think about this. I'm sure they spent lots of time and r and d coming up with what we are already using. However, they did have to work around emissions restrictions. Here is some dyno info I found on their site. A note above the dyno results mentions it caused the motor to run lean and enriching was required. http://boyesenc.nexcess.net/tech-center/v-twin-tec h-center.html#dyno | ||

I would love to be proven wrong, I just can't see how it would help on a XB. The stock airbox design to the best of my knowledge does the same exact thing already, in fact it probably does it better than Harleys equipped with this. The stock airbox has that trumpet of a velocity stack, airflow that goes straight down, then gently curves before getting into the motor. The 1125R takes it further and uses one throttle body per head, and when you twist the throttle you can see all the way to the valves  | ||

Boysen makes *great* reed systems for two strokes. So they have a good history in this space. That being said, putting more stuff in your intake isn't going to make more air flow as a general rule. We did some interesting things with jet engines and non laminar flow back in the day (golf balls do fly further), but that was by changing the path and shape, not reducing volume. So if I put two and two together, here is what I suspect: 1) Harley Davidson was much more worried about how it looks and sounds than they were about how it works when they built sportster air flow paths. 2) Boysen does know what they are doing and did a lot of testing and experimenting to produce the product. 3) As a result, they have created a device that helps compensate for some compromise Harley made of form over function. So I guess I agree with Froggy. At best it will help your sporty but won't do any good for a Buell (except maybe a tuber with a forcewinder, which is probably also a poorly engineered air flow path). At worst it does nothing for either. I can't see it helping an XB, though head porting and intake tuning has plenty of voodoo. |
