I fly the same plane as you. Also a LIV with the same engine and same empty weight, weird huh.
I use 2700rpm for take off with rolling the rpm back to 2500 within the first 500 ft of altitude.
My normal climb speed is 160kts seeing between 700 to 1000 fpm initially degrading with altitude.
By the time i get above 16000 my climb is down to 100 to 200 fpm with an indicated of 140 kts.
I normally cruise at 2450 to 2500 rpm, with a fuel burn of between 11.5 to 13.5 gph. I like to fly between
8000 to 14000. I always have oxygen on the plane for when i need it.
I routinely fly in and out of 3500 ft with 2 on board and 300 lbs of fuel. I have gone in and out of 2500 ft
Also but it just seems short although I still had lots of space left. With 600 lbs of fuel and 4 persons i can get in and out of 4000ft with no issues
although 5000 ft is more comfortable.
I still get some blowby with 160 hrs.

We are in phase one flight testing of our LIV (N304R).
In the initial couple of hours, our new IO550G had significant blow by. Now that
rings are starting to seat, power is improving. Using Cloud Ahoy and an AV8OR
GPS we are logging performance. Recently, our improving climb and cruise results
for the indicated conditions are:
Loading:
Empty 1950 lbs plus 550 lbs fuel
and pilot
Power:
Full throttle 2500
RPM
Best power leaning
Climb at 125 KIAS
Density altitude 11000 ft
1200 ft/min
Cruise at 12600 density
altitude
211 KTAS
We’d be interested in how this compares with other LIV
or LIVP results, especially below 18000 ft density
altitude.
