From memory, I have not had the Renesis over 6000 ft nor have I even
attempted to measure maximum speed above 2000 ft.

Thanks
for the info Tracy. Oddly, I've only done top speed tests above 5000 feet
recently, so I don't have anything to directly compare.
I'm
wondering what the "normal" best cruise speed altitude will be for
us. With a certified relic (engine), you're only allowed to run 75% power
continuously, so the best cruise speed is the highest altitude where you can
still make 75% power. As I understand it, that's about 8000 feet.
Van has always been irritated by people giving speed figures for RV's without
following the "standard" practice of measuring it at 8000 feet. In our
case though, we're not limited by the 75% power rule.
It's
hard to let go of the 8000 foot rule of thumb, but I guess it really doesn't
apply. I'm sure there's a level of HP that would be considered a safe max
for extended operation, but I have no idea what that is. Has anyone
designated a max HP level for
continuous operation?
