That's the oil gauge...
According to this modified article the 370z goes into limp mode at 280 oil temp. Oil starts breaking down near 300 degrees.
I'm sure it's probably starting to pull timing before that which is what you are experiencing. Sucks man...my 96 Cobra did that **** on hot days and it felt like driving a 4cyl. I installed an aftermarket radiator and a fan switch to kick on earlier. Neither worked. Later the factory came out with a TSB to install an oil cooler which apparently fixed it.

Edit: There is a mention of it here at the bottom of page one..

Two of the guys in the local Z club im in got oil coolers after the first couple thousand miles. One of them had to get an oil change at 1300 miles.
It gets to about 120 F in the day here and about 90-105 F at night.
We drove about fifteen miles (just normal driving) one night and both of the 370 guys said the oil hit 250 on there way there.
People are saying an oil cooler isn't the answer but until nissan does something,it is the answer.

Thats not typical at all, I've driven my car through DV where temps exceed that, as well as all over the Palm Springs area and I've never seen my temps exceed 230 and I dont have an oil cooler, going over 250 during normal driving is abnormal and they should have their cars taken to the dealership. Makes me wonder how high they were keeping their RPMs. Didnt the DE engines have oil burning problems? Especially 03's and 04's?

Initial 06 Rev-ups had the oil usage issue. This high temp stuff is unrelated to that (I believe that was a ring seating issue). Also note that a lot of 370Z owners report that as the engine breaks in, their running temps have dropped. Let's face it, when you are making this much power with this displacement, you're gonna generate some heat.

Without an oil temp guage in the 350Z, you have no idea how hot your oil is actually getting. The limp mode is a safety feature added to the 370Z. It was added after Nissan discovered that extended exposure to 300 degree oil broke down their newer style bearings over time. Most are missing that the engine isn't "breaking", it's just being protected at an arbitrary temp level by Nissan. I'd call that being responsible.

wow, are you insane? I had an 07' GT and was a member of club4g, they dyno around 220whp and 205-210 ft/lbs, good one though, that made my day. I had a Fujita F5 intake, RRE headers and a Magnaflow exhaust, end result? 271whp. 370Z's to include the Nismo, dyno stock between 275-290whp and 245-250 ft./lbs, depending on the dyno. My eclipse also weighed 3500 lbs.from this:

I wouldn't get an aftermarket cooler unless I were tracking the car or lived in a climate that got my oil over 250 regularly. I've heard an aftermarket oil cooler can play havoc with your warranty. I would however, be religious in my oil changes!

With the kind of outside temps that you're having, I'm guessing that you had your AC on? If the engine temps get dangerously high, shut off the AC, open the windows and crank up your heater. It'll make you uncomfortable as crap, but it'll bring the engine temps down.
Also, check your air filters. They might be gunked up and you're not getting good airflow.
