I've tried a thermostat twice and almost cooked my engine both times - so I have given up on one.  Besides, I can normally pick when I fly (being retired) and don't go flying when its cruel to my body.{:>)

I run a 160 degree thermostat in the cool months in the race car. I drill a 1/4" hole through the rim of the thermostat so any air can slip right through. Adding 1 teaspoon of dishwashing detergent, or Redline water,wetter, helps dump the air and helps cooling just a bit. The 1/4' hole will add some range should the thermostat fail. Use a make-up tank with a 22 pound Stant lever cap.

 

Don't fail to block the bypass hole and use a US style thermostat.
