[AZ986S]

Update...

I ran at Wild Horse Pass last weekend and the new engine performed flawlessly. Seat of the pants feels like more power than the old engine since it is a 2006 rebuild. I recorded some in cab video and was reviewing to see how often the accusump came on. In general, right turns will activate the accusump more than left turns. It never activated for more than maybe 1 or 2 seconds at a time. I had my passenger look at oil pressure and temperature (ambient air temp was 95F), and pressure never came much lower than 40 psi, temp never higher than 225F. I am using Mobil 1 5W50 oil. Oil capacity now is almost 11 quarts, so that probably helps in keeping oil temps down.

So I am very satisfied with the results. The next thing I would do is add a pressure sender to the air side of the accusump and a switch on my panel to use the existing oil pressure gauge to read the air preload pressure. This had been suggested by StevedOx.
