RE: "This ain,t america.If it doesn,t work,it doesn,t sell." comment......
Thanks Dude! :-) You may have us confused with some other part of the states. This is northern California.... Here is boots, Levis, work trucks, horses.....
We tested quite a few Hayabusas before we released the stacks.
As I say in most all of our website pages that are about v stacks, the type of dyno loading is critical to getting real world relevant power readings and we never know how dynojet or dynojet clone inertia loading will affect the horsepower curve. Sometimes it's better than what we did on a proper load dyno and sometimes it's not.
This time, the results were similar to our EC997 Eddy Current dyno results (whew!) - There was some discussion over here about not printing the real hp gains (6-8 True) and instead, just claiming 3 or 4 - but - what the heck - print the truth. (what's the worst that could ever happen on the internet?? :-)
As far as longer stacks always making more low and mid at the expense of peak and shorter stacks losing at low and mid....
Well - I used to think that, but, after optimizing stack lengths, inlet radii and inner diameter on literally 100's of bikes - I can say that, without a doubt, I can't predict exactly what a new engine wants until I try something different.
The R1, for example, gains mid and upper mid and some top with really long stacks - in fact, the top of the airbox is the limiting factor there. 89mm!
The Busa stacks? We have from 15mmm to 80mm in steps of 5mm and 10mm. Tried a BUNCH of them. That's a hint as to why we designed a quick change adapter rubber- The more changes you make, the more you learn and the better the product.
Our Busa stacks are different in 3 very significant ways over the stock stacks. Take away any one of the unique features and they won't work so well.
So - anyhow - just so you guys don't think that we don't read and care about the rest of the world.... we really do care.
So...... in jest... who's toes did I step on today (I'm usually good at it).
Have a great weekend -
Marc
ps: I'm still a bit perturbed that my friend from Sydney told me that you guys in oz call carrots: "washdykes" - and I told that story for 5 years to other people before he fessed up...... <i></i>
