I have made past posts about what I believed were poor climb and performance numbers in my O320 RV6a. Since then I have determined most of the problem was instrumentation and my numbers were not too far off of Van?s. So, about the time I was really starting to enjoy my fuel sipping O-320, my hangar-mate shows up with an O-360 C/S RV-4. Seriously!!!!! Now, I realize I will never be able to completely keep up with a smaller plane with no draggy nose gear and the same engine, but flying with him is beating my ego down like a red headed step child. So having admitted to being ego driven, and realizing I may not be able to pee farther, but hoping to at least miss my shoes, I?m giving an 0-360 some serious thought. I have a line on an O-360-A1D with a constant speed and have a few quick questions?. I have read the multitude of post in reference to 320 vs. 360 and it seems both sides have valid arguments (I do burn less fuel than my 360 brethren at the same speed, but would like the option to burn a lot more to go a faster). It seems those who have done the swap are happy with the results. What I can?t find is any actual before and after numbers on speed and climb increase. Any numbers out there??? Next question: I?m a little C/S dumb?. Since it is adjustable is it more likely it will be an acceptable propeller for my 6a? The propeller is a Hartzell HC-CZK-1BF / F7666A-Z?. Which could be the launch coded for the Russian nuclear arsenal for all I know. I believe it is 74 inches, which seems long to me? will this work? I realize this propeller has a 100 hour inspection AD? is this a major issue / expense?
On a side note, if I decide to pull the trigger I will have an O320 H2AD (314 SMOH 2900 TT) STC Ney Nozzle installation (for cam issue) completely baffled with a carbon fiber plenum and Sensenich metal FP and spinner for sale?.would be great for a 9 or any RV that is not shearing a hangar with a C/S 360!
