Does it do it all the time, or just when cold?

I have the same problem too; it is under boost, the more boost the louder. It sort of sounds like a deep wind. But as your boost drops off the noise goes away. I thought it was a boot but all the boots are fine, and I still have the noise. To add to what he said before under max boost 14-15psi every once and a while I get a clatter noise. Only a few times this happened my boost dropped for that second but I can't confirm that. Maybe I imagined it. And all these noises are not consistent. Every once and a while the noise goes away all together but for just that boost interval. What do you think?
