These babies should give a little more power

airbox was a right pig to get out

[mrwippy]

not seeming to be Thick but how do these get u more power ?

[silky22]

suck more air in buddy

[r1ninja]

They will just move the pwer to a different area. I doubt you'll get any more

this page describes it better than i can

so it just smooths the air flow out it doesnt actually let more in , as its the same diameter it cant really  . so i guess with a little bit of time and work u could smooth out the insides of a OE one

[silky22]

we shall see , i'm booked in for a dyno next week and at the moment it pushes out 169 bhp at rear wheel , dave jenkins who i had them off ( adam jenkins brother races bsb ) says they give bags more torque lower down.

I knew someone would pipe up with that one !

Used to be called ram pipes or bellmouths

[mrwippy]

surely de-buring all the bits out of the ram air ducts would help with airflow tooooooooooo

Dunno mate. The airbox doesn't look like a particularly good design. When you look at the dirt pattern on a filter it just seems to be using the ends.

Isn't it more to do with tuning the airflow ?

The latest R1 has variable length stacks that adjust height with the revs, so this seems to me like a compromise, ie. a couple of cylinders are optimised for mid range & a couple for high end ?

yep all tuning is a compromise. There is no substitute for CC
