On a C210, a loose turbocharger hose clamp allowed the duct to separate causing a power loss. During the emergency landing, a high approach altitude and speed required a go around into lowering visibility and ceiling. An FAA inspector questioned the reporter's airmanship.

Narrative:
Departed ZZZ1, VFR with intentions of picking up IFR clearance from near 'xxxxx' intersection. Entering cruise at 15500 ft eastbound over a 12000 ft broken overcast, ZZZ was visible when we passed over it. Suddenly without warning signs, the manifold pressure dropped precipitously from 31
