Well, I guess I have to hire someone at NASA to solve my problems. LOL. The oil cooler exit plenum was a total failure. Temps went up to 250 on climb out. Not much else to say. Dumping into a high pressure area is bad news and I'm not willing to add a draggy low pressure lip either. This exit made me lose 5kts as well so it's a total no go. Back to the drawing board again...like the 10th time.
