no there isnt.
And it is not called compressor stall or anything like that (wastegate chatter etc, its nothing like these). All it is is the dump valve isnt opening, because there isnt enough boost pressure, and some of the compressed air is feeding back down the piping through your turbo, and the turbo blades are cutting the air the wrong way.
(think of it like swinging something on a string fast through the air and it makes the "wooshing" noise)
Wether it damages the turbo or not thats for you to decide, some people say it will, some people say it wont, I think on low boost applications like a ct9 etc, i dont think it will. I have ran mine without for a year now with no issues... But some people obviously will.
