A few years ago I was at a shop where a guy was working on a IMCA car. He was running alcohol and maybe that's the difference but he was running a washer instead of a thermostat. If that will work for us I will make some for everyone so that a stuck t-stat will never cause an overheated motor again. I would have no idea what size to make them. I tried running without a stat back in high school in a Cougar and it ran way hotter than with a 180 stat. I was told that's because the water could flow too fast through the rad. and not have time to cool. I don't know if that was BS or not but I sure hate depending on a thermostat in my race car.
