Xona Rotor started in 2015 between industry leaders TiAL Sport and Forced Performance. Xona Rotor's mission is to set the standard for motorsport turbochargers, delivering the highest-possible level of quality and performance.
In Xona nomenclature, the first set of numbers refer to the mass flow in lbs/min. For example, an XR6564S has a 65lb/min flow rate. The second set of numbers indicates the turbine discharge in mm, in this case 64mm turbine discharge. The “S” indicates that the turbine is the UHF wheel aero.
