p4c3y Member 5 Member For: 13y 8m Gender: Male Location: melbourne Posted 31/03/13 05:35 AM Share Posted 31/03/13 05:35 AM G'day All. Just purchased my first fg after owning 2 ba xr6t's. My concern is the turbo makes an annoying howling noise off boost. howling gets louder the more revs you go (before boost) and howls down like a police siren when off the throttle. I havent really investigated much yet though when the turbo is shut off (car turned off) it spools down quietly like normal.What things should I check? I. eg, splits in hoses. loose hoses!? a tiny coyote in that pod looking thing at the turbo from throttle!I did notice this sound on my first ba when it was cold only. its got stat 3 month warranty but id like to sus it out before I take it in to get an lsd fitted next week incase I need to spend cash on it!

Basicly loud as Fek spooling up. But once on boost sounds like a normal fg (kinda supercharged) Link to comment Share on other sites More sharing options...
Boosted1 Member 346 Member For: 16y 1m Posted 01/04/13 07:34 AM Share Posted 01/04/13 07:34 AM def sounds like head droop, ive seen a few turbos develope it. you cant tell by looking at it as its the turbine wheel that has drooped slightly off its ballanced axis.
