but amount of airmass, isnt so big of a deal, than velocity and pressure. high pressure usually makes hi velocity. and you know that when you calculate force, the velocity means more than mass. but on bigger boost, the masses are bigger too.
we are talking here about a volume of air, certainly way less than 0.5 m^3 with a pressure of 1 or 2 bar above atmospheric going out through a tube with a couple of inches diameter (although much smaller past the turbine). how fast can that air be going? the force would be proportional to the volume flow. very fast air through a small tube does not create a large force, it creates a large pressure perhaps that could do some localised damage.

are you sure that it's the dump valve cannot flow enough, or just that the balance of spring and pressures is not correct?

the air must go past the compressor wheel whilst the pressure is higher inside the system than outside. it's nature. unless the system is sealed, which it is not as the compressor wheel has a clearance around it.

but in a turbo, it will be blowing equally on all sides so will not cause an imbalance.
good discussion so far
