Claim Text:
1. A fan housing comprising: a radially outer surface and a pair of radially intermediate features spaced radially inwardly from said radially outer surface, one of said pair of radially intermediate features including a first inner surface spaced towards a first axial end of said fan housing, said first inner surface having an inner bore positioned radially outward of an inner bore of a second inner surface defined by the other of said pair of radially intermediate features, a plurality of vanes extending between said radially outer surface and an outer periphery of each of said pair of radially intermediate features; a bearing bore extending radially inwardly of said first surface; a mounting lug nub formed on an outer periphery of said radially outer surface, a first distance defined between said first axial end of said housing and an opposed axial end, and a second distance defined between said first axial end and an axial center of said mounting lug nub, and a ratio of said first distance to said second distance being between 2.13 and 2.11; and a center of gravity existing for said fan housing, and there being a third distance from said first axial end of said fan housing to an axial position of said center of gravity, and a ratio of said second distance to said third distance being between 1.07 and 1.00.
