     DETAILED DESCRIPTION OF ILLUSTRATIVE VARIATIONS 
     The following description of the variations is merely illustrative in nature and is in no way intended to limit the scope of the invention, its application, or uses. 
     Referring now to  FIG. 1 , a product  100  according to a number of variations may include electric motor generator  1  (MG 1 ) that may be connected to a combustion engine  102 , for example but not limited to, an engine crank via a belt  106  or other structure for turning the electric motor generator  1 . The combustion engine may be a gasoline, mixed fuel, diesel or an alternative combustible fuel engine. An electric motor  2  (M 2 ) may be connected to an air delivery device  20 , which may be constructed and arranged to move, flow or forced air through a conduit  9  to the intake manifold connected to the combustion engine or two a turbocharger system  10 . The air delivery device  20  may be a displacement blower, a centrifugal compressor, scroll type compressor or other type of compressor. 
     The air delivery device  20  may include or may be driven by the electric motor  2  and may be utilized as a single or dual boost device operating alone or with a turbocharger system. By decoupling the air delivery device  20  from the engine  102  boost pressure can be immediately provide. This may avoid the non-optimum fueling required to reduce the lag time associated with a turbocharger and thereby may improve fuel economy. The electric motor  2  and the air delivery device  20  may be constructed and arranged to have near zero parasitic losses when boost is not needed and thus further improves fuel technology alternatives. A first power electronic module  3  may utilized to power and control the electric motor generator  1  and the electric motor  2 . In a number of variations a second power electronic module  13  may be constructed and arranged to power and control the electric motors  2  and/or other components of the vehicle. In a number of variations the system may be constructed and arranged to operate with multiple voltages within a single housing. In a number of variations a higher voltage than 12V may be supplied to the electric motor  2  to increase efficiency and make components smaller. In a number of variations the components may be constructed and arranged to deliver both 12V and 48V power. The 48V power may be delivered to systems or components in the vehicle that can benefit from higher voltage without having to run entire vehicle electric systems at 48V. One or more short efficient electrical connection  4  may be provided between the power electric modules  3  and  13 . 
     In a number of variations a scroll compressor may use two interleaving scrolls to pump, compress or pressurize fluids such as liquids and gases. The vane geometry may be involute, Archimedean spiral, or hybrid curves. One of the scrolls may be fixed, while the other orbits eccentrically without rotating, thereby trapping and pumping or compressing pockets of fluid between the scrolls. Another method for producing the compression motion is co-rotating the scrolls, in synchronous motion, but with offset centers of rotation. The relative motion is the same as if one were orbiting. 
     Another variation may include flexible (layflat) tubing where the archimedean spiral acts as a peristaltic pump, which operates on much the same principle as a toothpaste tube. They have casings filled with lubricant to prevent abrasion of the exterior of the pump tube and to aid in the dissipation of heat, and use reinforced tubes, often called ‘hoses’. This class of pump is often called a ‘hose pumper’. Furthermore, since there are no moving parts in contact with the fluid, peristaltic pumps are inexpensive to manufacture. Their lack of valves, seals and glands makes them comparatively inexpensive to maintain, and the use of a hose or tube makes for a low-cost maintenance item compared to other pump types. 
     A cooling system  108 , such as cooling passages  5 , which may include a water jacket, may be provided to cool the power electric modules  3 ,  13 , the electric motor generator  1  and/or the electric motor  2 . In a number of variations, a water cooling passage  5  may be include a portion which is common to the first power electric module  3  and the second power electric module  13  and may be interposed between the power electronics modules  3 ,  13 . In a number of variations a single housing  6  may be provided and may include one or more of the electric motor generator  1 , electric motor  2 , first power electric module  3 , second power electric module  13 , and/or the air delivery device  20 . 
     At least one energy storage device  7  may be provided dependent upon the application requirements. The energy storage device(s)  7  may be connected to the electric motor generator  1  to store electricity or the equivalent produced by the electric motor generator  1 . The electric storage device  7  may be connected to the electric motor  2  to delivery electricity or power to drive the electric motors  2 . A controller system  24  may be provided and connected to the electric motor generator  1 , electric motor  2  and energy storage device  7  as well as other components of the vehicle which may be connected to the electric motor generator  1 . 
     The controller system  24  may include main controller and/or a control subsystem may include one or more controllers (not separately shown) in communication with the components of the system  100  and/or other components of the vehicle for receiving and processing sensor input and transmitting output signals. The controller(s) may include one or more suitable processors and memory devices (not separately shown). The memory may be configured to provide storage of data and instructions that provide at least some of the functionality of the engine system and that may be executed by the processor(s). At least portions of the method may be enabled by one or more computer programs and various engine system data or instructions, energy stored device data, electric motor generator data and/or electric motor data stored in memory as look-up tables, formulas, algorithms, maps, models, or the like. In any case, the control subsystem may control engine system parameters or parameters of the system  100  by receiving input signals from the sensors, executing instructions or algorithms in light of sensor input signals, and transmitting suitable output signals to the various actuators, and/or components. As used herein, the term “model” may include any construct that represents something using variables, such as a look up table, map, formula, algorithm and/or the like. Models may be application specific and particular to the exact design and performance specifications of any given engine system or of the system  100 . 
     The electric motor generator  1  can be utilized for start/stop operation of the combustion engine  102  as well as regenerative engine braking to produce fuel economy gains. For example, a belt-alternator-starter (BAS) use of the electric motor generator  1  to start the engine  102  which may be connected to the pulley  104  which is operatively connected to the electric motor generator  1 . The product  100  may include electrical connections  8  such as wires for delivering 12V power to the electric system of the vehicle. Again, optionally, the system can deliver power other than 12V to the vehicle system components that can effectively use higher voltages such as, but not limited to, 24V, 48V.
