I will but I'm still testing a lot. It's very important I solve this and get adequate oil pressure or there is no way we can build a reliable engine.
I just relocated my turbocharger oil feed and it actually made a difference at the bearings (AC pressure port). I run a journal bearing turbocharger which runs an unrestricted oil feed so to some extent it will effect oil pressure on a car with oil pressure issues. I moved it from the oil pressure sensor location to the top of the driver's head.
It was a minor improvement and won't solve the "problem." For the rest of you track guys, if the low oil pressure isn't proof enough, you need to run way heavier viscosity oil! Do not worry about cold flow issues if you are running a synthetic oil. I had very good reliability at 350 whp when I was racing on Redline 40w race oil (basically it's a 10w40).
With 440 whp and 9k RPM it was a different story. LOL!
I may be fitting a new, larger oil pump by the end of the week.
