Ran some autocross couple weeks ago and trying to get ready for next week's runs. Back story, it was 95+, and 100+ on the pavement by the late afternoon runs and my motor was screaming "what the h*ll are you doing to me!?". Gotta re-run due to a red flag on the last run but by then i was at 210-220 easy and there was no way I was gonna get the temps down quick enough before grid closed.
Let the car sit for 15-20, all was fine, called it a day and drove home. Did some investigating, and decided to take a look at my 180* thermostat. Never thought it would be a problem. I noticed the motor had been running fine all year but gradually starting creeping up. Idle temp was reading mid point 190-195 vs 180 low where it'd been most of the year. Picked up a high flow thermostat and threw that in the car and sure enough, the temp is now reading on the low end, 180*, infrared shows the same.
Is this possible? I suspect the high flow pump was partially closing my stock thermostat when I was up the rev's and my motor, radiator & fan couldn't recover fast enough. Also a check of the stanton thermostat with boiling water showed it opening at 190-195 rather than 180, though it was supposed to be a 180* thermostat. This thermostat was barely a year old.
Something as simple as a darn stock thermostat causing all kinds of havoc. Let's see what happens this weekend with the new high flow thermostat.
