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.
