"Another improvement that BPE made was in the gearbox. The M14P is a geared engine with a ratio of .658:1. This gearbox appeared to be inefficient and robbing horsepower. BPE used their magic and cleaned up the gearbox, sending this wasted horsepower to the propeller where it produces thrust. Long story short…BPE created 50 additional horsepower by making a good engine… GREAT!"
