| Quote: | One last comment I will share from the same engineer at Van's I spoke with that day. He said, "it has been their experience that an RV-7/7A Lycoming 0-320 160 HP is the BEST engine/airframe combination...". I've flown both a 180 HP RV-7A and my 160 HP model and the only difference I can tell is climb in the 160 HP airplane is about 200 FPM on average less than the 180 HP. Oh.. and I burn about .5 to 1.0 gallons less per hour... thus extending my cross-country range. I fly 4.0-4.5 hour cross country legs and always have an hour or better reserve when I land.
Sorry Ron... I know you are an advocate for 180-HP or better in the RV-7/7A but I venture to same more of us live and fly from airports at/near mean sea level than 7KFT in the mountains... I've flown my RV-7A from airports at 9KFT density altitude... no problem!

Nice try Jack. I flew from 00V to east of Albuquerque and back non-stop and
had about an hours worth of fuel left. I would need to find the flight log to
give you the exact amount. The flight duration was about 4.4 hours. And that
was starting with six gallons LESS than a RV 7(A). Actually I will say that I
had 46 minutes of fuel remaining.
Thusly therefor I don't buy the argument that a 180 HP burns more fuel than a 160 HP
all other things being the same. That comment is based upon going the same speed
versus same percentage power setting. But given all that people will do whatever
they wish.
Thanks for the lead on the flexible valve stem extender.
