Turbo Whistle... Possible Fault??

(1/6) > >>

Pullafacial:
Hi guys, not sure if it's a problem or not but on the way to work today I noticed the following:
Whilst I had the window down under hard acceleration, the "whistle" noise from the turbo seems to gradually get louder then gets to certain point (around 3000 revs) and then suddenly drops right back.
It's almost as if it gets to a certain point then looses pressure or goes into safe mode or something??

Anyone experienced this before? Maybe that it's normal but i'm just curious.

All gears? Mine does this in 2nd under normal acceleration, foot down hard and it struggles for grip. 3rd gear upwards it pulls all the way and whistles like mad  :driver:

Remapped?

Pullafacial:
Happens in all gears and not remapped (although thinking about it!)

Steve

Nickyboy:
But it still pulls as strong when the noise dies down?

Saint Steve:
What turbo is it.?? k03 or K04.

K04 is alot more audible especially on throttle lift off.
