I've been experiencing overheating during the races and have been making changes to improve cooling effectiveness. After doing NORC-2021 at 135 I installed a large aftermarket aluminum radiator, 165 thermostat and oil cooler, but the car (Pontiac Trans AM) is still running hot. This past May I ran NORC at 145 and going north it was running even hotter.
For Sept, I've switched over to using Water Wetter, have funneled more air to radiator and installed a hood louvre.
I'm also looking at my electric cooling fans. They come on based on temp so they come on at approximately 200 and will stay on.
Do the fans being on at these speeds help or do they obstruct air flow?
Do folks know if their fans are on or off at the higher speeds?
Thank you for any feedback,
