Great data above AZ986S. I installed of the accusump on my '01 986 S, in the tunnel, it fits well and seems to be the most logical location.
Here is a video of the results on the track with track tires. I run my oil level about half way between low and full, with this set up I get an accusump dump on almost every corner and even under heavy breaking. Based on the video there are even a few longer corners where the accusump runs dry. Running Mobil 1 0W-40, BTW. Accusump has a 35PSI valve with 10 psi of pre-pressure in the air chamber.
I also run into very low oil pressure at idle post track sessions, i.e 5-7 PSI at idle and 250 F oil temp.
Conclusion: If you're tracking a 986 or 996, strongly consider an Accusump or deeper oil pan, you'll need it.
