roastbeef wrote Any track car people get rid of the heater/blower and regret it? I can't think of a single time at the track when I needed to defrost the window… But it probably has to do with my location.
Just some food for thought: During an event I was once driving in, during late Fall at Road Atlanta, back in the nineties in a Porsche 944S2, I learned the value of a good heater blower. It had been misty and cold that morning before heading out on track. Then it started to rain. Lightly at first. The rain quickly got harder and the ambient temperature dropped. I was having trouble demisting the windscreen, because the heater fan in the 944S2 was either barely working, or not working at all (later on it was determined to have a bad ground). Anyway, even my helmet visor started misting up which was easy to fix by just raising it, BUT the only real place for me to wipe the inside of the windshield was on the back straight, which is a pretty fast strip of asphalt in North America. I ended up using one of my racing gloves to wipe the inside of the windshield for a few laps, before having to pit and collect some rags. It was a good lesson learned. In summary; IF you do remove the heater blower have a plan for demisting the inside of the windshield when you're racing in the rain.. Or just carry some rags, but of course those add weight..
