I've just fitted a new CAI, I know your going to think this is all about the turbo whistle but it isn't a whistle it's a quite a pronouced Whine (screech but not very high pitched) at WOT... does this mean the turbo is dieing?

If it helps, it sounds like a mechanical baby crying, WAAAA

Which intake have u fitted? The sound that you get is very much determined by what make of intake you have fitted!
-
does it sound like this? specifically from 1.00 to 1.10...
If so, it's normal. Well, for a twintake anyway..not sure if other kits make the sound, but its caused by the same effect like if you were to blow air through a length of hose with an open end. A whoooooo sound :happy2:
-
^^^ That's blow off sound...
This is at full WOT, lots of whistle but then whine - bearing / leak?
Will try and take a vid.
-
No I mean the 'whoooo' sound before the blowoff (1.00 to 1.02) which is caused by air moving through the pipework...maybe this is what he was hearing, but possibly louder in a single-cone kit?

Yeah, it does kinda sound like those 2 secs you described (thanks btw) but for much longer... it's over a few thousand RPM then dies off at later revs (starts at around 2.5kRPM till 4.5k @ WOT, then disappears) there was a good Volvo 850R video which did the same thing, but I can't find it.
It's a bit annoying tbh... I get all the intake and blow off sounds, had them on a few motors... but this just sounds wrong; self-destructive almost.

Tried to take a vid today, but you can't make the noise out... it happens everytime at WOT below 4k then stops... any ideas?
-
Tried refitting it, but it still makes this noise, anyone else experience the kettle boiling noise with their CAI?
