The CSL noise...

[windy]

So, what causes it? Is it one specific thing, or the result of a few things?

[windy]

Oh, and I know it's induction-noise, but I wondered what specifically.

[SMD]

Its the airbox and the airbox only mate!

[Mark CSL]

The airbox lets the noise of the valves and the air being sucked in that big flap :hahaha: big flap that always makes me smile :hahaha:

[mattbedford]

Its such a spine tingling sound. I cant get enough of it. I think it sounds really deep and snarly at about 3,500rpm in third gear and accelerating hard...:drool:

unless your flaps arent working!

I will most likely be proven wrong, but it was my understanding that the 'flap' was there to regulate and indeed reduce the noise and does not add or create the noise.
As far as I am aware you can actually remove the flap if so desired, then again maybe I'm talkin sh1tee :whistle:
The sound is created simply by air induction resonating through the carbon airbox

Yeah, just take it off, haven't noticed any problems with it since I did just that.

[SMD]

Yep no flap here!:thumbs:

[Nords]

Working flap here!

who knows but if its broken, it brakes closed so NO NOISE:bigcry:

[glendog74]

As much as i'm a fan of 'flaps' - i don't have one in my airbox anymore! :hahaha:

[Bealo]

Yep, mine has gone too.... :thumbs:

[bryce]

Think I'll need to try this 'flapless' thing. Though Im always in Sport so would I even notice a difference?

Does it change the sound between idle to 3k rpm?

[SMD]

Yep noise all the time!:beer::smokin:
