I've seen 100-101C on my PFC a few times after getting stuck in slow traffic on I95 around 4:00 at 90-100F ambient. anytime that its under 85F outside though, my car runs 85-90C consistantly. Its really weird, pretty sure its because of only having one beat up oil cooler and no radiator ducting right now... i'm working on it.

i get awefully paranoid around 100C though, which i suppose is pretty stupid of me to do.

Don't mean to hijack this thread but how about everyone's opinion on normal operating temp for Oil? Mine runs around 190-200F all time.

Holy crap when I saw the first guys temps, thats "China Syndrome" hot. I thought things started to melt at 220F.

My old SMIC set up 85-103c , my new single turbo set up 82-86c

It will probably depend on what model FD you have (dual/single oil coolers) but.....

Thanks Sgtblue. I got single oil cooler and looks like it falls within reasonable range.

Instead asking about regular oil/water temp question, I think the question shoulbbe "What water/oil temp will be the danger zone that everyone should be aware" or pull over?

really!
what happens when u shut the car down then start it back up 15mins later? doesnt pfc read 110ish? then quick;ly drop.

112 * C at Beaverun Flat out racing day.

At that point I took the car off the track and limped it home, there is an oil leak somewhere that I am trying to diagnose :(

I see 89c max on a 100f degree day boosting with A/C on
I have a koyo rad and vmount..single turbo
At normal cruise with A/C on I max out at 87c and with A/C off I max out at 84c all on a 100f day
