What is it?

Just follow the link and draw your own conclusions.  I'll button my lip on this one.

I can remember a whole card full of similar gadgets hanging on the shelf at a Texaco station I started pumping gas at when I was about 11 years old.  In different sizes for different carburetors.  It was up there next to the curb feelers and aerosol windshield deicer that would last about three squirts.

...and the magic magnetic fuel line wraps to give you 50 mpg.

I have the dyno.

Lets all place bets and I'll test it!

I would be shocked to see if this actually made a difference...   Even the dyno on Boyensen's website shows such a small difference I would chalk it up to differences in outside control factors.

Steve it would be awesome if you test it. You never know.

Once you spend $100.00 on a gadget like this,

you want it to work.

when I evaluate products like this, I ask myself a simple question.

if this really works why don't manufactures use them.

the simple answer to this is often just as simple,

they have looked and evaluated them and determined they do not work.


believe it or not, GM and the oil companies did not conspire to kill an engine design that does not burn fossel fuels,

just to make themselves richer. They would be far richer if they had said device.


I would also guess that this would not be the biggest monetary mistake made in the quest for more power.

Many of us have made far worse mistakes  

PS. A riding buddy of mine has also bought one of these, it is real hard for me to keep my mouth shut as he

pontificates how good this is. He was slow before the device and still is slow.

I have to wonder a little about the folks who came up with the info I cut from the website and attached below.  That device didn't change the air flow at all in the drawings until after it passed the slide in the CV carb and got over to the actual throttle plate, where the air flow mysteriously smoothed out.  That is one tricky little piece of tin.

I'm somewhat bewildered on one or two claims.  Assuming that this device somehow manages to "straighten and smooth" the air flow through the carb throat (or throttle body), how does this do anything for a port injected engine?  The engine doesn't know to add more fuel to go with this supposed higher velocity air (higher velocity, not volume, still makes no sense but let's go with the flow for a minute), and the better mixing claim probably isn't going to fly either since the fuel and air don't really mix in a port injected engine until the fuel meets the air in the port and in the combustion chamber.  So somehow this higher velocity air in the throttle body is going to make the same quantity of fuel produce more torque and improve mileage at the same time by 8%.  Now that my friends is some damned impressive engineering, accomplished with about 50 cents worth of tin.  I'm impressed!

There have been hundreds of similar devices promoted in the automotive world over the past 30 or 40 years.  The biggest surge came after the oil embargo in the 70's, and we see increased activity every time fuel economy becomes a big issue, like last summer.  My favorites usually involve some form of wire mesh device that sits between a carburetor and intake manifold to "straighten" air flow.  The better versions are made of wire coated with "catalysts" that start to "process" the fuel before it even gets to the cylinder. 

The EPA has tested hundreds of these kinds of devices over the years, and has not found a single one worthy of recommendation.  As Keats mentioned, assuming any of these things actually worked, what makes anyone think the manufacturers wouldn't be all over the thing?  They want to sell vehicles and meet fuel economy regulations, and if they could get better mileage with such a tiny investment they would have all kinds of mesh plates and fins and other stuff stuck on the intakes of their vehicles.

Just installed the Boyensen X Wing this afternoon. After a test ride the increase in power is noticeable in all gears!! Comparable to the power increase  achieved by adding a stage 1 kit (high flow air filter & exhaust) to a stock bike. Sort of like a stage 1 kit X 2.

What a surprise, a product that does what it claims to do.    

I've tested all these types of gadgets on the dyno - here's my .02
They are air restrictions and may have a small positive effect on torque in a carburetor equipped bike that is jetted incorrectly and restrict top end power.

On EFI bikes they do nothing to a properly mapped bike and actually restrict top end power.  Sometimes you'll see a miniscule increase in torque as you've restricted the intake but the flip side is the drop in top end power.

Don't believe dyno sheets that are a couple of horse different because i can do that all day by manipulating temperatures.  When you look at a dyno sheet it should have notes with all the ambient conditions, engine temp  - etc if doing a comparison to prove or disprove a product.  I would suspect that the power you feel in all gears is your want that it works.

REmember the "TORNADO" for automotive uses?  so while thier logic is to create a vortex of air, we're trying to straighten it out.

[grc]

Many of the purveyor's of these devices rely on the general public knowing just a very slight amount about air and fuel from reading Hot Rod or Motor Trend, and then using a few well chosen buzz words in their ads.  Turbulence was the big one for carb engines, as in more turbulence in the carb and intake manifold helped mix the fuel and air and keep it evenly mixed for better combustion.  Thus devices like the Tornado.  Then along came port fuel injection and we didn't need turbulent air in the throttle body and manifold for air fuel mixing because no fuel was in those areas.  So now they promote "straightening and smoothing" the air flow through the throttle body.  Of course, what they don't mention is that all that "straightening and smoothing" gets undone at the throttle plate. 

Don't get me wrong, intake tuning does work, just like exhaust tuning works.  But it is dependent on lots of factors, isn't a one size fits all proposition, and is only effective at certain rpm ranges.  Thus it requires extensive testing and engineering to match up the intake, heads, cams, and exhaust to reap the benefits.  Thinking someone can just come up with a one size fits all device that will provide the same benefits as thousands of dollars worth of parts and engineering is wishful thinking at best.

IMHO, the first tipoff on many of these devices is how they claim they work equally well on carbs as well as EFI, and don't even offer a different part number for the two versions.  It's been my experience in life so far that one size doesn't fit all worth a damn, and that the majority of product claims are written by people with no actual knowledge of the product or how it supposedly works.  They study human behavior and how folks react to certain words and images, not how products actually work (or don't work).  The words and images can be totally opposite to reality, such as the ones with the carb on that web site, but they are counting on the fact that if it looks scientific a large number of people will believe it.  The smaller number of people who actually know the claims are bogus don't matter, since they wouldn't have bought the product anyway.  And thus the world of creative advertising and bogus products rolls on.

BTW, I'm not trying to make anyone feel bad or stupid because they believe in these things.  What each person believes or doesn't believe, and how each person spends his or her money, is not for me to say.  I just offer my comments for those who don't know what to believe.  This stuff persists because people buy into the hype, and then tell their friends how great the product is to reinforce in their own minds that they didn't really get scammed.  Trust me, I did the same thing after spending $30k on a POS motorcycle a few years back.

Anyone ride a motocross bike? The dude that made this wing ain't no joke.  He owns more performance patents than anyone else in the sport of motocross. Yes I used to ride motocross. I put one in my 09 soft tail. Works awesome, pulls better on and off throttle and seems to pull harder. For me, money well spent.
