Has anyone installed an IO-240 (125 hp) in an RV-9/9A?
Given the RV-9/9A fuel capacity (36 gallons), the IO-240 burns 7 gph, and would give the RV-9/9A an endurance of 5 hours without reserves verses the IO-320's fuel burn of 9 gph, which givings an endurance of 4 hours without reserves.
Additionally, the IO-240 is lighter that the IO-320. 240 lbs verses 278 lbs.
Curious about performance of this engine/airframe combination. According to Van's website, Van estimated the RV-9/9A with a 135 hp engine would cruise (75% @ 8000 ft) at a gross weight (1600-1750 lbs) speed of 174 mph (150 kts).
If real world performance numbers for the FADEC controlled IO-240 in the RV-9/9A were close (160 mph/140 knots) to Van's estimates for the 135 hp engine above, then I think this might be a good engine/airframe combination for my flying requirements.
Does anyone know if the IO-240 in the RV-9/9A will cruise in the 160-170 mph (140-150 kts) range?
Thank you.
