I signed up for a day at Thunderhill next Friday the 19th so we'll see how it goes ambient temps will likely be in the upper 90's to 100. At autocross on Saturday ambient temps were around 75 and my temps would be at 250 after each run so I'd spray the intercooler, oil cooler and radiator with the distilled water & isopropyl alcohol mixture by the start of my next run temps would be at about 230 but they never went above 250. Also noticed that ever since I've been running the distilled water + mocool in the radiator my highway temps have been around 230 instead of the previous 250.
