42.3 hours of very smooth operation. Oil pressure is exactly the same as first time I ran it (39.5 psi at cruise), so I suspect it's running well. I plan to pull the bearing/cover off at 100 hours just to see how things are going, but I don't expect to find anything but smooth surfaces. Somebody at Corvair College asked what kind of fuel consumption I get at 75% power, and I couldn't really answer it since I don't usually run it wide open at cruise, so I did that test on the way home. At 7400' wide open, I was burning 5.1 gph turning 3350 rpm and getting 171 mph true airspeed, which translates to 33 mpg. I usually fly higher than that and throttled back to about 3050 rpm, so on the way over I was at 11,500' getting 48 mpg at about 150 mph TAS. I was also in the middle of recalibrating my fuel system (having replaced the fuel flow sensor along with the front bearing engine swap), and did the final "balance" after landing. It's now accurate to within .2 percent, which is as close as the calibration procedure allows adjustment for...close enough for KR work...
