that is certainly some interesting info

sounds as though it is entirely aimed at racers though, the points i got from a brief read of all that: removing the entire airbox is BAD + through some resonating magical effects add power if the airbox is designed perfectly??

im not an expert at hydrodynamics but i have a fair bit of knowledge in the area and i found the resonating stuff to be rather unbelievable, in some cases im sure it can be of benefit but in generic use i was under the impression smoothness is of more benefit than turbulence (resonations would cause turbulence would it not?):eatcorn

i thought everyone had the same conclusion that a custom airbox, exhaust and then a power commander to set it all up sweet was the way to go

thanks for the interesting read nonetheless :thumbup
 
I thought it was pressure waves that formed from one valve closing sending the pressure wave back hitting another just as it was opening that gave the airboxes and the bellmouths the power.
This was to do with the length of the bellmouth/trumpet. A longer one giving more torque and bottom end and shorter ones giving a better top end.

Hence the new yamaha throttle body bell mouths that lift off to give a shorter stack to give a better top end.
 
a mate of mine bought an old 97 HRC cbr 600 (carbs) and the airbox was like nothing i had ever seen. All the intakes were different and it had all sorts of channels and cut aways in it. I don't know anything about it but surely they know a thing or two about it and don't spend that kind of money on negligable gains.
 
my zx7 has a ex bsb carbon airbox on it and it's as smooth as anything but it is huuuuge
