It definitely isn't that the motor can't accept the air flow. A VF34 is not a large turbo and not pushing that great of a volume of air through. It is all down to the actual design of the turbo since nearly every VF34 makes this noise.

My guess is either the design of the impeller or being a ball bearing turbo, it allows the impeller to spin more freely than other bearing types (i.e. allows the impellor to slow down quicker causing the chomp chomp chomp of air).

Ignore it as it is a fact of life with these turbos.
