Method for manufacturing a turbocharger assembly having a thermally decoupled flange

A method according to claim I further comprising:

• providing a turbine;
• connecting the turbine to a shaft;
• and
• disposing the turbine in the turbine housing and the shaft through the shaft bore of the housing body.

A method for manufacturing a turbocharger, the method comprising:

• providing a turbine housing defining a gas passage extending from an inlet to an outlet and configured to receive a flow of exhaust gas therethrough;
• providing a rotatable turbine in the turbine housing, the rotatable turbine configured to be rotated by the flow of exhaust gas;
• providing a center housing having a housing body defining first and second opposite sides, a shaft bore extending between the first and second sides, a coolant passage configured to receive a coolant fluid, and a mounting flange extending generally radially outward from the first side of the housing body;
• connecting a connection portion of the mounting flange to the turbine housing such that a curved portion of the flange defines an annular space between the housing body and the connection portion of the flange;
• connecting a compressor housing to the second side of the housing body;
• providing a compressor wheel in the compressor housing;
• and
• connecting the turbine and the compressor wheel with a shaft extending through the shaft bore of the housing body.
