I'm not 100% sure on the temps, but I've definitely hit the 5000 RPM limiter limp mode on the track before without an oil cooler.
I am not a fan of limp mode.

Wait -- you are talking about the Z's limp mode.

Never mind.

OP, fab up a removable block off plate for the oil cooler. Plenty of threads on here describing them and even some with pictures. Just do a search. A 34 row cooler is a lot of oil cooling on the street even with some spirited driving.

A 34 row is overkill for any N/A street driven Z. If you are staying N/A and not tracking a few times a year then a 19 row is PLENTY of cooling. OP, make a simple block off plate like gomer suggested and cover 60-70% of your cooler. You wild only ever need to take it off if/when you track.

A 19 row cooler is only plenty if you live in a place with moderate summers ("in my opinion" and all that)

Limp mode is 280F. I was at 275 on the dragon. I need a couple of parts to install my oil cooler I took off my totaled car. You don't have to wait for the oil to warm up to drive the car hard. As long as the water temp is up to operating temp, you are good to go. In hot South Ga. summers with an oil cooler you will see 200F cruising down the interstate at 78mph. So the oil is actually 220F coming out the engine. The temp sensor is after the oil cooler.

I haven't been on this forum for quite some time. It's interesting that oil temperatures are still a topic. What is hot and what is too hot always makes an interesting read.

I was quite surprised to see a 235F oil temperature in my Cayman GT4 while driving on an interstate highway in 80F weather. My first trip to the track netted a 245F peak temperature. On the second trip it was warmer and the oil temperature went to 254F. Porsche considers this normal for the GT4. Under the same circumstances my 15 GT3 runs at about 205F on the highway and doesn't get above 235F on track.

I had one of the first 370Zs in my area and the reason for selling it was oil temps hitting 240F. Fast forward to the GT4 and that temperature is considered normal. I was surprised to hear that from my SA.

Oil analysis on the GT4 factory fill Mobil 1 0W40 showed no issues at 2000 mi. including 2 track days. Changed to Motul 5W40 X-cess.

My opinion is run a quality oil and change it more often if you track the car. Especially so in hot climates.

I can safely say I was at 130*c/266f and didn't hit the first limp mode. I am Ecutek and oem "oil cooler" tho.

On the dragon on my first run. I will just say spirit animal took over and I just went with the flow. Initial d san drift style.

Edit actually hit 125*c/257 so yea didn't hit the limp target
