I feel like this is a stupid question but...

So I have a S/C Z and I am wondering what the normal temps are for like the engine oil, tranny oil, coolant, and diff oil.

What temp levels should I get worried at?

 

I've seen 248F as a max acceptable engine oil temp, but in general engine oil loses effectiveness as once it heats up much past 220 from what I've seen/heard. Not sure on non engine oil though. Definately search, this is a common topic.

 

ok my oil is fine my coolant hovers around 199 and when in bumper to bumper 214-219 depending on outside temp

 

That's pretty hot for coolant, water boils at 212F at sea level. Granted antifreeze increases the boiling point and I've seen 226F for 50/50 water/coolant. I'd check with other SC guys and what/if they've done to cool that down. Can't say if that is an issue or not, but seems a little hot. My coolant doesn't get that hot on track days, it maxes out about 210F.

Right now I'm testing 100% water and Redline Water Wetter, but don't have any track days to confirm it how it handles extreme heat. It's behaving just like the antifreeze/water mix for DD running about 180-200 in a stock VQ35HR.

 

Do you have an oil cooler? I think any FI application should have one. How did you measure you coolant temp because as stated already, it seems pretty high.

 

yes I have a oil cooler for the engine oil, power steering, and transmission oil.

have a new gauge for oil temp and normal running temp is 100c (212f) - 112c (236). i feel that is really high... car hasn’t died yet and has had 35k with the super charger.
