Oh crap. What should I do?

Note that the coolant temps were just over 210F, normal.. A lower temp T stat would have helped a tad, but not much as the oil temps are at such a great differential to the coolant temps.. Oil temp is just that, oil temp.

The key is:
1- Run an oil developed to operate at temperatures in excess of 250F for sustained periods of time without a loss of pressure or lubricating properties

2-Run an external oil cooler.

NOTHING else is going to be the answer.

The reason why these engines run high oil temps is their tight clearances coupled to tons of friction from 24 valve springs, 5 timing chains, 7 main bearings and etc... The engine is a friction nightmare, so its hard on oil.

Adding a larger oil pump won't make the issue any better, thats just going to make the oil HOTTER!! Bigger pump= even more friction.

Some oils can run 250F+ sustained without issue, but these oils need to be changed every 5-700 miles and cost 13-15 bucks per quart. They do not work well at lower temperatures. Thats the difference in a "race oil" and "street oil".

Either keep the temps down and pressure up or use an oil that will maintain pressure at temperature.

Either way, the issues we see with failed engines on the track aren't from G force aggravated starvation.
