Oil temperatures in the pan and oil cooler inlet can run 250F. Feed cooled oil to both the PSRU and turbo. I see a 15-20F oil temperature rise at the PSRU drain at 38" MP and 10F at cruise power <30" MP / 4800-5200 rpm. Bobby Sent from my iPad

Here's the drain.  I seem to recall that this is where Tracy told me to put it a couple years ago.

Still working on the supply.    Has anybody used post-cooler oil to feed the PSRU?  Is that ill advised?  Seems fairly straight forward to do it that way and would eliminate a bunch of 1/4 line.  <image.jpg>
