Naming Convention
As we launch new turbo models, we are also updating the naming convention to the commonly used, inducer of compressor, exducer of turbine, preceded by the compressor aero utilized in the model. An 'S' at the end, still indicates if the turbo utilizes the UHF™ splitter-blade turbine wheel or if absent an 'S' the turbo model utilizes a traditional full blade design. Example: XRE7169S
The previous models use nomenclature where 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.
Easy difference on model naming is if it has three letters which is new model naming: XRE, XRC or XRA and use CW inducer/TW excucer. Previous Models were only XR and use flow rating/TW exducer.
