oh, where the radius of the lip equals the radius of 'A" |

Cool! It makes a lot of sense to me that this shape would be better. |

Phew! Glad to see this thread getting back on track.
Whodom - Interesting point. If you think about how the air enters the airbox through the filter, you can see how some of it has to flow up the outside surface of the stack, around the "trumpet" and then down the throat. You could easily CNC a better outside shape. It might end up being a fairly heavy piece of aluminum though. If you consider Oconnor's idea, it would be lighter, but that open lip would disrupt the airflow IMHO.

How about this shape for some "outside the box" thinking.....  |

nice idea, but the radius of the top edge is still too small in the illustration for the size of the throat. 'Stuffing' the airbox with a larger stack also reduces its volume. Flow in airboxes is not constant and not just about achieving the smoothest entry. In some systems, ostensibly 'dead' areas have their part to play as charge reservoirs and dampeners. This helps big v-twins like the Honda VTR carburate at low speeds with huge venturi.
Bottom line, you may find a compromise which is better for your riding-style, but there is no free lunch here. |

How about a donut tin shaped base in the airbox to create a mini vortex to speed the air drag up into the stack?

jersey guy, I think that the "lip" on your stack s going the wrong way. Think "O" and not "U". But how did you draw that? what software... Mac compatable? |

why not add another gear to the end of the cam gear train, and run a centrifugal blower to pressurize the airbox? not a whole lot, just maybe around one atmosphere. that would eliminate any worry about airhorns, intake porting, etc. BOOST. |

Ok, apparently the stack is just some bling bling. 
Anybody think what I'm thinking when looking at this http://www.zex.com/store/merchant.mv?Screen=CTGY&Store_Code=ZX&Category_Code=EAA ?
For some reason my brain flashes to the view of an XB12 inner air cover. Then I start wondering if it's possible to jet down to just a 10-15hp squirt.
Anybody tried a dry nitrous setup on a FI Buell? |

They were showing that two weekends ago on High Rev Tuners, while I was getting ready for a ride with the Tuscon crew...I was actually joking with Bartimus about that idea using the 12 airbox and having the nozzle come right down the little "nipple". Probably use on of the wet kits from NOS or Nitrous Express...

I'm rather intrigued with the idea of the dry setup if I was sure that the ECM and injectors could keep up. Wish I could afford to trash a motor right now, if necessary, to test the theory.
I think a stock lower end could withstand 10-15hp every once in a while.
It would probably be difficult but it would be cool to have a progressive squirt based on throttle position. |
