Oil pump getting tired?

I was seeing oil temps as high as 220-230, with water temps at 195. John Williams was not concerned, and he built the engine.

Om my VW I've seen oil pan temps as high as 240 degrees. I'm not sure what the oil temp is after going through my cooler though. Water temp is 180-190 even on a warm day. Because of this I don't really worry about the oil temps because if the oil wasn't doing it's job the water temps would be higher.

At idle my hot oil pressure does drop to less then 20 lbs. sometimes dipping to as low as 10 lbs but jumps up to 40+ psi with just a blip of the throttle and never drops below 40 lbs while on track at speed, sometimes going as high at 70 lbs psi.

I go by the off time mentioned advise of 10 lbs of oil pressure per 1000 RPM engine speed. I have it so I don't worry about the bottom end at this point.
