Whining under load

[Talon_Tsi]

My car is making a strange whining sound under load, while I'm making boost. The sound goes away when I let off. I don't start to notice the noise until about .5 bar (about 7.4 pounds). I havn't changed anything on my car for a few weeks, so I have no idea what the problem can be. Performance doesn't seem to be affected anyway, but the noise is annoying and I have no idea what is causing it. Any ideas? Thanks in advance.

If its a whining, I'd check your turbo for shaft play. Then tend to whine when they are on their last leg. If its more of a whistle, I'd check for boost leaks.

if it sound like a supercharger stop driving it and get rid of the turbo, trust me thats all u need to know
