Gutting or Removing the Thermostat

[RETed]

I've run my FC with a gutted thermostat and NO thermostat.
For day-to-day street driving, it just takes a little longer to warm up.
Mind you, I live in Hawaii with relatively warmer ambients.
It just takes a few more minutes to get to temp (above 160F).
I would NOT recommend this if you see anything close to freezing temps.

For racing, when the engine sees sustained revs, you need the restriction to minimize hot spots, as others have mentioned.
For street driving, you just eat up more gas due to the engine staying colder longer.
