My stock radiator would climb at the racetrack, caught it at 250 or so and had to short shift on a 85 degree day.

Today in bowling green track, 30 minute sessions, 95 degrees, it stops at 212, but I did see 216 max. DeWitt, also a big mouth. Had the big mouth on the stock rad, but wasn't enough. I also have manual switch to turn the fans on, I leave it on all the time during track use and it makes a difference.

Oil temp stays steady at 250. Hair below the caution bars.

I think the radiators all mentioned are plenty good.
