System for controlling an electric assisted turbocharger comprise an electric motor disposed within turbocharger, and an electric motor controller electrically coupled thereto for purposes of controlling the same. A memory is electrically coupled to the electric motor controller and is configured with a condition map that correlates electric motor instructions with engine and turbocharger conditions. The system includes sensors that are electrically coupled to the electric motor controller, and that are configured to sense conditions of at least one of the turbocharger and the internal combustion engine that is coupled thereto. The electric motor controller is configured to control the electric motor based upon the input received from the plurality of sensors as compared to the data contained multi-dimensional condition map. The system provides electric motor speed control, boost pressure control dampening, and can be used to produce electricity from the electric motor depending on the particular operating condition.

A master cylinder as set forth in claim 8 wherein said second portion is further defined as having a circular configuration of uniform thickness. 10. A master cylinder as set forth in claim 9 wherein said second portion is further defined as having a half-circle configuration of uniform thickness. 11. A master cylinder as set forth in claim 8 wherein said first portion includes a connecting surface between said first and second mounting surfaces and planar surfaces between said first portion and said first and second mounting surfaces. 12. A master cylinder as set forth in claim 11 wherein transitions between said planar surfaces and said first and second mounting surfaces are at obtuse angles. 13. A master cylinder as set forth in claim 11 wherein a transition between said connecting surface and said first mounting surface is at an obtuse angle. 14. A master cylinder as set forth in claim 5 wherein said at least one aperture further includes at least one inlet aperture formed within said outer wall at said first mounting surface and at least one outlet aperture formed within said outer wall at said second mounting surface. 15. A master cylinder as set forth in claim 5 wherein said at least one aperture further includes at least one mounting aperture formed within said outer wall at said first mounting surface. 16. A master cylinder as set forth in claim 15 further including a mounting hole formed within said first thickened section and aligned with said mounting aperture. 17. A master cylinder as set forth in claim 16 further including a reservoir mounted to said body wherein said reservoir includes at least one mounting flange disposed within said mounting aperture. 18. A master cylinder as set forth in claim 17 wherein said mounting flange includes a notch aligned with said mounting hole. 19. A master cylinder as set forth in claim 18 further including a retainer disposed within said mounting hole and said notch to secure said reservoir to said body. 20. A master cylinder as set forth in claim 19 wherein said retainer is further defined as a ball which is inserted into said mounting hole until said ball aligns with said notch and said mounting hole. 21. A master cylinder as set forth in claim 19 wherein said retainer is further defined as a slug having a first condition integrally formed within said mounting hole and a second condition wedged between said mounting hole and said notch. 22. A master cylinder as set forth in claim 5 further including at least one piston disposed within said bore and further including a brake booster with said flange mounted to said brake booster. 23. A method of manufacturing a master cylinder having a hollow body with an end wall and a mounting flange, said method comprising the steps of; extruding the hollow body to define a continuous outer wall extending between first and second ends having a longitudinal bore formed between the ends; forming the end wall on the first end of the outer wall simultaneously with the extrusion of the hollow body to close an end of the bore; positioning the flange over at least a portion of the second end of the outer wall; deforming a distal portion of the second end of the outer wall; and interlocking the second end of the outer wall with the flange during the deforming of the distal portion to integrally mount the flange to the hollow body. 24. A method as set forth in claim 23 wherein the step of deforming the distal portion is further defined as bending the distal portion outwardly toward the flange. 25. A method as set forth in claim 23 wherein the flange includes an inner notch and wherein the step of interlocking the second end with the flange is further defined as compressing and deforming the distal portion such that the distal portion extends into the inner notch and interengages the second end of the outer wall to the flange. 26. A method as set forth in claim 23 wherein the step of extruding the hollow body is further defined as
