Did some searching with no definative answer. I put mine in yesterday but wanted to see what you guys are running and why. Factory 195, optional 180 or no thermostat? What are you running why you are?

 

Why in the f would you not run a thermostat?
I learned a long time ago that running colder than stock was stupid and pointless. But perhaps there's something different about track that I don't know about. Doubt it.

Takes longer to warm up, and if your heat exchangers are not up to task, you'll still overheat.

 

Ha, I agree but just thought I would throw it out as an option as I know some cars that do not run thermostats (not miatas)

 

NA's actually had a 180 degree thermostat stock. I seem to remember reading that the switch to 195 was emissions related. I've always run a 180 in my miatas, since I feel like that was what it was designed to run.

 

I think mine is a 180*f. I never, ever go over 200*f.

 

You should just not run a thermostat (ie, just remove it completely). Its "better" for flow

 

Flow is power.

I only use my thermostat when my engine is cold. After it warms up I turn it off.

 

Gutted thermostat on my track cars with a reroute. I am told it is not the same as no thermostat by people who know more than me about this kind of thing, so I go with it.

 

Wow harris, sounds like you're trying to pass visual inspection or something.....lol. Let's keep the BS to a mimimum guys, dont want the noobs to get confused.

 

So you're getting confused?

 

I am pretty sure that you should run the Stant 180 degree thermostat on the miata, no matter what the car is doing.

 

Can you share why youd run the stant single valve unit over the OEM double valve unit?

 

You are "the newbs".

 

 

hahahahaahahahaahahahahaaha....*breath*...hahahaha hahsahhaahhaahhaah!

 

Run a thermostat. If you don't...

at speed, coolant might flow in and out of the radiator without having time to cool.

Do what you want (because racecar). And *uck you know who.

 

Contact hyper...
...He will hook you up so good your engine will freeze

 

lol @ this thread.

 

The stock thermostat in my 1990 was 195. The stock thermostat in a 2002 I changed recently was a 180.

I think the 180 reduces thermal spikes on track for me over the 195

Theseus has a gutted thermostat because it doesn't have any other coolant lines (no heater core, no oil warmer, etc).

Rover has an M-Tuned reroute with the factory oil warmer lines capped, but it still uses a heater core which allows flow before the thermostat opens.
