An Eaton M62 Roots-type supercharger is visible at the front of this Ecotec LSJ engine in a 2006 Saturn Ion Red Line.. The Roots-type blower is simple and widely used. It can be more effective than alternative superchargers at developing positive intake manifold pressure (i.e., above atmospheric pressure) at low engine speeds, making it a popular choice for passenger automobile applications.
The scroll-type supercharger is a scroll compressor used as a positive displacement orbiting-spiral supercharger. It is a compromise between the more rugged rotating lobe, and the more efficient sliding vane type superchargers, and is considered to offer the highest potential in regard to efficiency, noise and pressure fluctuation.
Positive displacement superchargers deliver an almost constant level of boost pressure increase at all engine speeds, while dynamic superchargers cause the boost pressure to rise exponentially with engine speed (above a certain threshold). [4] Another family of supercharger, albeit rarely used, is the pressure wave supercharger.

Distancing the supercharger from the engine via a mounting bracket greatly reduces heat transfer from the engine to the supercharger during operation. By comparison, a twin screw or roots blower which is nested in the center (valley) of the engine, will absorb heat (heat soak) during operation due to thermal transfer from the engine block and ...
Washington Commanders running back Austin Ekeler was placed on injured reserve this past weekend after he sustained his second concussion in a span of just two months.
These dogs are truly deserving of a little fun in their lives. As the rescue themselves noted, many of the dogs are in hospice care with cancer, renal failure, or other serious health issues. So ...
Shelby Ford Racing Whipple Supercharger kit in either 525 hp or 624 hp configurations, Shelby cooling system and front splitter. Although Shelby did not independently confirm the performance figures, a 0–60 mph (97 km/h) of 3.7 seconds and a quarter-mile in an estimated mid 11-second range has been estimated. [citation needed]
