Howling sound from rear?

Does anyone have an idea what it is i'm hearing?
Under load there seems to be a howling sound coming from the rear of the car. It is not loud at all, but definitaly not previously present. It seems to follow the manifold pressure meter from my turbo gauge but slightly out of phase (trailing) I've been driving Saab Turbo for some years now including the Classic T8 with bad Turbo, but I've never heard this before. It's definately coming from the rear. I would even guess its coming from the rear left side. Although pinpointing the origin a sound is always difficult in a car.
Are there any vacuumlines in the rear of the car?
Any ideas?
