No, not the dump valve sound... its on the intake...
When I boot it and am on boost the turbos spooling makes a kind of chirping or clicking noise (more clicking than chirping really)
I happens more on the first turbo than the second.... and it reminds me of the noise you\'d get if there was a bit of plastic touching the turbo rotor fins as they spin round... *click* *click* *click* increasing in speed as the turbos spin up faster... :eek: :eek: :eek:
Had a quick brainwave that it could be something to do with the air intake (faulty air filter on the intake???)
:confused: :( :xconfused :eek (smiley overload)
i have the same but i think... it went away when i removed my boost controller and then came back. now i think its the solenoid - boost conrol valve for the boost controller.
interested to know though.
Is there any play in the shaft?

Dunno, will check.
I think it used to do it ages ago too, but went away...
have you got a front mount intercooler?
yup, big jobbie...
i had what sounded like R2D2 getting electricuted on ma starlet lol, turns out it was the fmic pipe loose and causing a winney woohoo clicky noise lol.. jus thought id mention it lol
do you have the profec ebc ?
it is the greddy solenoid that makes that noise at it opens and closes to control boost..
dunno what profec ebc means LOL...
But my original spec did say it had a Greddy VVC - never did find out where / what that was LOL... could that be it?
It hasn;t always made this noise..
