Water got to 240* and oil went to 285* in less than 10 minutes starting out at 130* in ~85* weather, anybody else have temps this high?

Modded much? I hit 230 for coolant on stock radiator and with no oil cooler my oil got that high too. With a dirty radiator I overheated coolant and hit over 300*F oil, but it was 100*+ that day too. I thinned my coolant to ~30% with water wetter and pressure washed the radiator and that helped a good bit. Oil cooler keeps me under 260 now.

Two things I saw on that video:
1. Run a cool down lap. Seems like you were hard on it until you came in the pits. Drop her into 5th or 6th, stay off the brakes, and slow way down. Temps will come down quickly.
2. Especially in traffic, shift up a gear. The lower revs will greatly improve cooling, even at the same speed.
BTW, was this an instructor's group or does no one do point-bys? Seems like you were working pretty hard to get past the cars you were catching.
HTH, and have a good one,

It's got h/c. Radiator is clean, I'll have to add the oil cooler. I pulled off as coolant actually came out the overflow and dropped under the tire as thats why the rear got loose going into last corner. Drove it around the parking lot to cool it down quickly. Thought about the fact I should have just ran 3rd the whole way around to lower temps a little. They have a flag man, but most were not paying attention to him and have an ego lol. The thing that I didn't like this year is that you had to pass off line on the straight which makes it more difficult with less power...
