You can up the take off power in the IO 550G to 310HP by simply increasing the rpm to 2700.  Same engine as a IO550N.    Make sure FF is about 25gph and you will see increased performance.  Works much better in a LNC4 non P.

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.
