Turbo housing element

1. A turbo housing manifold, comprising:

a planar base plate comprising a radially-extending overhang defining a first opening; and

a housing conduit portion connected with the base plate and defining a second opening distal from the first opening and axially aligned with the first opening to form a fluid passage between the first opening and the second opening, the housing conduit portion defining an inner surface, the housing conduit portion further including:

a first extending portion proximate to the base plate and extending axially away from the base plate; and

a second spherical extending portion connected with the first extending portion and distal from the base plate;

wherein an inner surface of the second spherical extending portion transitions from a larger radius to a smaller radius as the second spherical extending portion extends away from the base plate;

wherein the overhang extends radially into the fluid passage beyond the first extending portion of the housing conduit portion.

2. The turbo housing manifold of claim 1 wherein the second opening is smaller than the first opening.

3. The turbo housing manifold of claim 1 wherein the second opening is in a serially downstream flow relationship with the first opening, and wherein the second opening defines a flow area of 2552 millimeters squared.

4. The turbo housing manifold of claim 3 wherein the first opening defines a flow area of 2812 millimeters squared.

5. The turbo housing manifold of claim 1 wherein the first opening and the second opening are coaxial.

6. The turbo housing manifold of claim 1 wherein the first extending portion is a cylindrical portion.

7. The turbo housing manifold of claim 1 wherein the second spherical extending portion is at least one of a semi-spherical portion or a hemi-spherical portion.

8. The turbo housing manifold of claim 1 wherein the housing conduit portion defines a sidewall having a uniform thickness through the first extending portion and the second spherical extending portion.

9. The turbo housing manifold of claim 1 wherein the first opening and second opening are annular.

10. The turbo housing manifold of claim 1 wherein the transition of the inner surface of the second spherical extending portion defines a radially slanted inner surface.

11. The turbo housing manifold of claim 1 wherein the planar base plate further defines a seat configured to receive the housing conduit portion.

12. The turbo housing manifold of claim 11 wherein the seat is defined by at least a first axial interface edge and a second radial interface edge, relative to an axis defined by the first opening.

13. The turbo housing manifold of claim 11 wherein the seat defines the overhang.

14. The turbo housing manifold of claim 1 wherein the planar base plate defines a hexagonal perimeter.

15. The turbo housing manifold of claim 1 wherein the first opening is centrally arranged relative to the base plate.

16. A turbocharger assembly, comprising:

an upstream turbo housing having a fluid inlet and a hollow passage fluidly coupled to the fluid inlet; and

a turbo housing manifold coupled to the upstream turbo housing to define a flow passage through the hollow passage and the turbo housing manifold, the turbo housing manifold further comprising:

a planar base plate comprising a radially-extending overhang defining a first opening fluidly coupled to the fluid inlet; and

a housing conduit portion connected with the base plate and defining a second opening, the housing conduit portion further including:

a first extending portion proximate to the base plate and extending axially away from the base plate; and

a second spherical extending portion connected with the first extending portion and distal from the base plate;

wherein an inner surface of the second spherical extending portion transitions from a larger radius to a smaller radius as the second spherical extending portion extends away from the base plate; and

wherein the overhang extends radially into the flow passage beyond the first extending portion.

17. The turbo housing assembly of claim 16 wherein the overhang defines a seat of the planar base plate configured to receive the housing conduit portion.
