Arrow Comparing water and air temps. Post yours.

After driving the other day, I checked my water and air temperatures on my power FC commander.

This was after moderate driving, and letting the car idle for about twenty minutes.

The water temperature read: 195.8 °F - (91 °C)
The air temperature read: 116.6 °F - (47 °C)

This is what I saw during driving.

The water temperature read: 188.6 °F - (87 °C)
The air temperature read: 98.6 °F - (37 °C)

I am just curious to see what other peoples temperatures are, and whether or not mine are too hot/cold, etc.

My water is about 195 driving, but cools to 180's idling. Can't say what my air is while driving. My engine bay heat soaks like a **** though. I see 140 air temp after driving around and letting it idle. I'll have to do some logging and see what's going on during driving.

IAT as well. I have a standalone, so no AFM.

Tonight I drove my car and noticed the water temp reading was 213.8 °F (101°C). Doesn't that seem insanely hot? I know I should be running more water, but in a 50/50 mix, would too much antifreeze cause this sort of reading??

213* isn't too hot. Were you driving it hard? When things start getting north of 220* I start thinking about cooling off; that hasn't happened on my street car, but temperatures like that can be normal when racing. Heck, my electric fans don't even kick on until 205* (thanks arghx.)

I do run the stock clutch fan. From what I read, the clutch fan may be screwed, and I really need to run more water than coolant. I'm really considering an electric fan.
