you should get some turbo whistle/whine but it shouldn't be that noticable.

My last 300 did this (sounds cool though), it was my top intercooler hose, you couldn't see anything physically wrong with it but when it boosted it opened it up, not a big job to take them off completely and check them

While you're checking the intercooler/turbo hoses for holes, also look on the inside of them and check for de-lamination of the rubber.

This may not be the problem now but if the hoses are old then this can cause loss of power and is worth checking while you're looking at them anyway.  :wink:
