Have 6.5hrs on the New Test Engine (Named 1622 Big Torque Zipper) Amazing performance thus far. Ended up pitching Prop 1.5 degrees over Stock 912 ULS seeing an increased climb VY 400-500 greater than stock. Seeing increased TAS of additional 10-12mph. Still able to climb at 500' min at over 14000'. No increases in CHT, Oil Temp or Water temp, 4000' hard climb VX today showed max water temp 203. Max Oil & CHT temp 194.
