nah not for a car with big cams that idles around 1000rpm... really thick FMIC and alloy radiator don't help either, it needs plenty of airflow so putting around in traffic doesn't help
when you see 110º+ water temp its time to worry... what temp does coolant boil at, anyone know?
now an Evo tuned to run 98 running 91 on a 40º day, that sounds unhealthy lol
