Thread: Strange Turbo noise

I've noticed a strange noise from the turbo on the fender. At normal revs it just makes a little whistle as it gets going, but at higher revs (under load), the turbo suddenly makes a high pitched whirring/whining kind of noise.
I think the 90 degree rubber pipe on the left side of the turbo is a bit soft, but I'm not sure this is the problem.

Any ideas?

Thanks, I'll go out and have a fiddle today. Might still replace the rubber hoses with silicone ones anyway.
