An assembly comprising:
- a turbine housing that comprises a bore, a wastegate seat and two wastegate passages that extend to the wastegate seat;
- a rotatable wastegate shaft configured for receipt by the bore;
- a wastegate arm extending from the wastegate shaft;
- and
- a wastegate plug extending from the wastegate arm wherein the wastegate plug comprises a profile defined in part by a portion of a torus, for contacting the wastegate seat in a closed state, and defined in part by two plug portions, for defining clearances with respect to the wastegate seat in an open state wherein in the closed state each of the two plug portions of the wastegate plug extends into a respective one of the wastegate passages.
