Hidden turbo noise ?
I've searched and also looked at diagrams etc but need some more info/ideas from thos in the know......
Over the last couple of months I've noticed I can hear the turbo air whoosh between 1500rpm and 2500rpm. Now it's not loud, but I can hear it if I put the window down. It is a kinda Darth Vadar breathing sound, very faint. the sound probably continues right the way through the rev range, but I can't hear it due to either engine noise or road/wind noise if at speed. It's more than just the sort of turbo flutter "dolphin" noise it makes at about 2000rpm sometimes.
Car has recent upper and lower silicon hoses. No power loss or running issues.
I used to get a turbo whoosh when I blew the flexi section in the exhaust, so I've looked at joins etc near the front of the system, but can't see any signs of a blow.
It may just be a normal sound for my car, but just want to make sure.
Anything else I need to check ?
