Post your Coolant temps during Road Courses or AutoX

[TDavis]

I wanted to create a thread that people could come to to see peoples setups and what temps range they should be seeing during a Road Course or AutoX session depending on the setups.

Post your cooling setup, the ambient temp outside, what event/track you're doing, oil temp, and lastly what your coolant temp range was during that time.

Example:

Cooling setup: Mountune radiator and Motorcraft 180 T-stat.
Event/track: Road course at Heartland Motorsports Park
Ambient temp: 70-75 degrees
Oil temp: ~230-240F
Coolant temp range:195-205F

I don't track my Fiesta anymore, but I do have old AiM datasets to review, so I'll toss in some of my highest temps:

July 14, 2019
Cooling Setup: Mishimoto radiator, Mishimoto oil cooler with thermostatic sandwich plate.
Event/track: Motorsports Ranch (Cresson) road course, 1.7 mile configuration
Ambient temp: ~72-94 degrees (looked up historical weather data)
Oil temp: not sure, I have no oil temp sensor so my AiM Solo 2 didn't record that
Coolant temp range: 192-228F

Cooling setup: Mountune rad, oem tstat (2018), mostly water+water wetter
Track: Streets of Willow
Ambients: 80s with a peak of 87f I think, low humidity
Oil temps: 230-240F (accessport readings)
Coolant temps: 220-230F

I dont think I bled the coolant correctly before that event, water temps could have been lower

Autocross this weekend. Hopefully I remember to get some data

Had autocross today. Ambient temp was 87 degrees and my car never got hotter than 217. Completely stock untouched cooling system. 2016 MY

195-205 coolant
225ish oil temps
Motorcraft 180tstat, mountune rad and IC

Cooling setup: Mountune Rad with Motorcraft 180 T-stat
Track: Heartland Motorsports Park
Ambient Temp: 94 degrees sunny
Oil temps: 230-240
Coolant temp: 210-218
Coolant temp without heat on: 218-223

Was definitely pleased to know the Mountune rad held up and kept the car cool. Ironically my friend who has a Stock cooling FiST went into limp mode on the first lap.

Good to know as I have a Mountune Rad sitting in the garage. Just need some other parts so I can do a bunch at once. I've though about switching to a 50/50 or 70/30 mix of distilled and coolant to run year round (because Texas) but I keep deciding against it because it seems like I'm one of the lucky few that doesn't overheat easily. I've seen less modified FiST's go into limp mode mid run at autocross while I'm sitting at 220 after a harder and faster run lol. I would no doubt overheat doing HPDE but that's for next year.

Is it hard to replace the thermostat if you're already doing the radiator? Seems pretty easy to access if everything is already removed

I think when you replace the radiator at the same time it'll be a little easier. I replaced mine later on and it was tedious since the radiator was already in there. Thermostat is doable, just not fun

do the 2018 cars have colder set thermostats? just did my mountune rad but not the tstat bc lack of time & laziness...

 

[Erick_V]

Bump. I also want to know what year they changed the thermostats, want to know this info before I decide to buy gaskets

This past weekend at VIR, HPDE with ACNA PCC:

Cooling setup: Mishimoto radiator
Event/track: VIR Full
Ambient temp: 65-73-ish
Oil temp: ~215-228F
Coolant temp range: n/a

Above is before my radiator install

Cooling setup: Mountune radiator, 70/30 mix w/ water wetter
Event/track: Autocross
Ambient temp: 80-85 degrees
Oil temp: Didn't look
Coolant temp range: Max indicated 202, leveled around 187 after running heat between runs
