It is the bypass valve.

And it is probably not defective. The problem occurs as you get on the throttle and the manifold poressure is increasing. At some point, there is still a minor vacuum and the valve is just starting to seat it self. Remember that it is open at idle. As it is lightly seated it will honk. If you remove and clean with warm water and detergent, it will improve a bit.
I fitted a TurboXS 25mm bypass valve to eliminate the noises. It worked. There are a few other piston type bypass valves available which would work just as well.
