ProCharger has announced the immediate availability of their newest self-contained supercharger unit to their family of industry-renowned units: the F-3A-121. This new model joins the decorated and distinguished line of F-Series superchargers and meets the guidelines for several 
categories, including the NMRA Super Street Outlaw eliminator.
“Overall, our goal has been to design it for optimal performance for a specific operating range that appeals to a variety of racing classes,” says Dave Werremeyer, Motorsports Operations Coordinator for ProCharger. “Using our new aerodynamics test lab, we also have been able to document reduced discharge temps and a reduction in parasitic load from this new model.”
In development since the fall of 2010, the new -121 model is slightly smaller than the F-3A-123 model, both in inducer diameter and vane tip height. Like all of the legendary F-Series superchargers, the -121 sports an exclusive CNC machined billet aluminum housing, patented ultra high speed bearing assembly, an aeration pump that provides self-contained oiling for superior bearing lubrication, an industry exclusive 7075 T-6 billet impeller, and other great features.
The F-3A-121 carries an MSRP of $5,699 and is available though all ProCharger dealers.
