The HP spool turns at 31,500 rpm while the LP spool turns at 19,444, reduced to 1,700 for the propeller: a 11.4 reduction ratio. Power can grow by 25% within the same size.

The engine was originally called the TPE331-16, but by 1988 it was renamed to the TPF351-20. The "TPF" represented "Turbine PropFan", while the -20 suffix indicated the 2,000 shp (1,500 kW) nominal thermodynamic power rating.
