Will have to be a 6MT person I think. On 7AT, I've never actually tried putting my car in neutral on the freeway and revving, but sitting at a stop it rev limits at like 5K in neutral, you can't go higher unless you're in gear and moving.

Travis,

I was using 6900 as a shift point at Mid-Ohio last week when I hit 275. At the time the ambient temp was around 65.

I think every one pretty much understands/assumes at this point that if you are going to track your car you need supplemental oil cooling.

Honestly, I have no data to back this theory up... other than an observation that folks on this board with 6MT seem to be the only ones overheating to the point of limp mode (so far!)...

That does make some sense but when I'm doing something like running the Dragon, I'm in manual mode and "shifting" just about as much as anyone with a 6MT would be so it still would seem like a bit of a mystery. :driving:

We had temps around 90 here yesterday and I only saw around 225 on the interstate and that was with the AC on (6MT here BTW). Is it possible that Nissan has made some change (even as simple as recalibrating the temperature sensor)? Based on my VIN number (51XX) I'm guessing that my car was produced fairly recently and I haven't had any problems, granted I haven't pushed my car yet to the extent that I would on the track or even auto-x.

I think us Phoenix residents are going to be the canary to the summer overheating problem. we are already hitting 100 degree days. Highest temps i have seen is 220-230. I am still in the break in period and rarely shift over 4k.

alan93rsa 04-24-2009 10:44 AM
I've seen 240 on a 75 degree day here in Ohio. That is also pretty close to the temperature I saw in my 335i.

I believe your are correct, Phoenix may be the canary.

Good luck.

Ok, so what is the "danger zone" temperature. I know the Z manual says 280 and up, but what is the consensus on the forum? Is it that anything in the 240-260 territory is red zone?

Being worried at 280+ sounds about right. The reason myself and others are concerned when we see 240-260-range is because we're seeing those in relatively light conditions/driving.

According to my guy (in my post a page or two back), temps in that range in/near the pan (which appears to be where the sensor is taking the temp) would not be a problem.

Yep, I saw that post Robert. Thanks.

Running up the I-5 this week from Sylmar to Santa Clarita at 80+ with the A/C on up the grade through the Newhall Pass. Same weather...never got above 230. Go figure. :ugh2:

How many miles on your 370Z? Thanks.

Robert_Nash 04-24-2009 02:21 PM
I likely have one of the first 370s in the country and am not, in my view anyway, having a problem. So I don't think the theory that something has been quietly changed works.

even a basset hound needs more than a couple data points to make a conclusion - smart as they are! :)
