Are you looking for a centrifugal or roots supercharger? Roots http://www.summitracing.com/parts/wnd-77-174fsb-1/overview/make/ford centrifugal http://www.summitracing.com/parts/pax-1001864sl/overview/make/ford
yep.. usually far better to steal something elses place as close to the front of the crank whenever possible than have to be moved all around and heavily offset. Fewer variables = fewer potential issues. Although.. for lower boost/rpm/hp.. not really a huge difference one way of the other.
Most of the centrifugal blowers sit on the passenger side; except for the Procharger, that sits on the driver's side.
