I'v data log my oil pressure many times through Cal Speedway's long banked T1-T2. 18 degrees of banking and I'm on slicks and flat out at around 152 in 5th entering the turns. I have the X51 oil pan only and I see only a slight drop in pressure. I see more of a drop hitting the brakes hard on a flat track from anywhere above 100mph. I now keep the revs up as I downshift...

Odd. I've done more than a fair share of DEs on my car over the 8 years and never an issue. I do have an X51 oil pan for a last couple of years, but I also make sure the oil level is always at the top during the course of an event and it almost requires some topping off between 2 days.
Sorry to hear about the attrition.

Mine does for about 3-5 seconds and I've been told this can be minimized if I run it with a little less oil. Just curious as to what you see on yours?

After installing new AOS I have no smoke whatsoever.

I would love any more information on the "oil pressure in the turns" thing. I've watched many 996s during DEs/track sessions and the gauge(s) do dip down to 2-3bar in turns almost regardless of RPM. I don't know the significance of this, or what causes it?
RE: Smoking at start up after track sessions. I've seen several 996s do this and many that don't. I find the failing AOS a plausible explanation but didn't try that.

I will be digging in soonish and will keep you all posted on the findings. I picked up a 3.4 leftover from a 3.6 swap today.... I will do my best to treat that car right.

I love it when new owners come on the boards and keep the car in the Rennlist family, congrats on the car!
