My track car is pretty sorted for heat, I can do 20 minute stints screwing it and temperatures remain very stable, oil temp dont go above 90 degrees, unless hood scoop blows off then it goes to 110, water temps stay around 85.
I run oil cooler in the Tmic position, aftermarket radiator with oem fans and oem shrouds attached, hpc coated everything, that made a huge difference to track day temps and temp stability but yes it's not a cheap option but by god it works. IAT temps were pushing 50 degrees on track now stays in the 30's, this is doing 1 min 15 sec laps around Pukekohe constantly for 20 minutes, this is at mid boost (25 psi) on shitty zestino road tyres.
