This bit on the oil pump performance was the highlight for me:

"This allows the sump to supply constant and secure oil pressure up to sustained 1.2g's. They call this a 'twin-flow' gear pump."

I ran Daytona recently and some in the group were seeing up to 1.3g's on the banking. I got to 1g at Nascar Turn 4 before my brain signaled my right foot to get off the floorboard!
