about 1.2 seconds off my PB. Car was indicating 109*F air temp in the track. Weather app showing 105*F. Car did fine, was matching my previous PB until T12. I was distracted by the heat and some new test brake pads I've never ran so T12-T20 I was braking way early and that cost me a PB (driver error really). Good news is even with this insane heat, car plateaued around 230 coolant. Oil was getting preeeeetty high so it would not last a full session at full tilt. Could use another oil cooler but I don't think i'll ever drive these temps again, too uncomfortable.
