What are the opinions of installing an IOX-370 or O-360 in an RV-9(A)? These engines produce more HP than the recommended HP for this aircraft and of course generate more stress and higher airspeeds. Are there any downsides?
There are no structural design reasons that preclude a Lycoming 180 HP engine from being installed in the RV-9/9A, as long as Vno (180 MPH IAS) and Vne (210 MPH TAS) are obeyed by the pilot. Regardless of engine power, the pilot must ensure that he/she does not exceed the design speeds at all altitudes.
I am dreaming about what engine would be good for my new to me RV9A flying aircraft that presently has a 0-320 B1A engine installed. I plan to remove this engine and either rebuild it myself or may be upgrade to a higher HP engine instead. For you RV 9 folks what would be your dream engine over...
I have a 9A with O320 and 9.0 cr. Im seriously thinking of going with as a minimum a stroked O340. It does perform good with 160+ hp but more for the long climbs would certainly be nice.
For 12 yrs I had an RV 4 with 180 hp O360 and I do miss the performance and yes, if I didnt know what the difference is it wouldn't be a big deal. But I do know
