Hi Wayne,
If the re-circ valve is staying closed when accelerator is depressed, or if the recirc is of diaphram type and has a hole in it, then yes, you'd likely get the noise.
I've never known it cause any problems to the turbo's, however weary when it comes to the GT range of Garrett turbo's because the core is narrower, and even though i am not a fan of dump valves, the recommendation would be to fit a dump valve.
