The lowest (80 RRPM for 250 watts) and 2 highest numbers (280 RRPM/6000 Watts/ 8HP, and 330 RRPM/10,000 watts/ 13.4 HP.) are extrapolations from the middle data. 126-220 RRPM are from actual data logged testing. 23' Dragon Wing blades using a 2 stage chain reduction with estimated efficiency of 92%.
