My 2009 911 wont heat up past 200 - is this an issue?
So I keep reading to let the engine heat up past 200 before driving over 4k rpm's etc etc
My car gets a hair under 200 but never over it. I just drove 20 miles at 70-90and it wont even touch 200
Is this an issue?

Oil or water? My water temp gauge never moves passed 175°F. Oil temp moves between about 200 and 225°F depending on how I am driving, running 100+mph for a while on the highway seems to warm it up the most. Right now with this cold weather in Texas, I wouldn't be surprised to see it a touch lower.

EnergyTrader....same with my 09. I was getting right AT 200 on the warmer days we had back in early Oct. But most of the time, especially on the highway, I stay around 175, maybe a little higher. The only time I can get it to stay around 200 is on back road drives where I'm driving hard. I think we'll appreciate the additional cooling once the temps get HOT.
FWIW...I don't think I've EVER seen 225 degrees since I've owned the car he last 10 weeks.

After I put in a lower temp thermostat, mine won't generally ever hit 200 either. I'd say it hits about 190 and then stays there. But, the summer never really gets above 80 here, so I think that's partly to blame as well.
I consider 190 to be my operating temperature. In order to get it hotter, I have to run the RPMs in the 6000 range. Then I can get it up to maybe 225 at most.

After reading the posts, it seems every car has a different temp at which the needle stabilizes, eg 175-200. Does anyone know if this represents inaccurate calibration of the guage, or different engine operation/cooling etc in the cars. If the latter, why would it be so ?.

I don't think you need to be that precise. 190F - 200F I add some driving time to the warm up, waiting 5 or so minutes before moving well past 4k.

There have been comments on the water temp gauge never getting above 175. For some reason it sticks in my mind that Edgy (Dan) was the expert on this. Don't quote me but I think he generally said that the cars were engineered so that the gauge sticks at 175 degrees not because that is the temperature all the time but because the gauge moved around quite a bit (which the engineers considered normal) and people would bring their cars in for servicing because they though something was wrong. (That would be good for dealers and bad for PAG/VW warranty reimbursement.). This doesn't mean that you should not be concerned if the gauge moves, it's just what I remember about why it stays planted in the 997. Now, some please correct me if I have mis-spoke.
As a data point, on my 997.1, on the track, the gauge would go up to about 200 degrees but it hasn't moved from 175 degrees in my 997.2. All this while oil temp. gets into the 250 plus range. Oh, and slow bumper to bumper traffic on the highway when temps are above 70 or so causes my oil temp to hit about 225.

That's fine. I think the PDK cars run hotter (oil temps). My PDK car will go above 200 in bumper to bumper traffic or on warmer days. The 2011's on have 3 radiators for that purpose. I think you need to let oil get to 175 before you push hard. Going 90 mph on a freeway is nothing for a 997. That won't cause oil temps to go up very much. Even in my PDK car..

Water temp: the gauge is simplified. I've need running a data logger lately and my water temps regulate between 180 and 203 degrees. This is based on driving everywhere from Bay Area bumper to bumper traffic to hot laps at Laguna Seca. The needle never moved from 175.
Oil: this gauge seems to be more accurate and reflective of what's really going on. On track I can see temps hit around 250, on back roads 225 or so but on the highways with cold air blowing over the radiators this time of year 190 seems about right.
It's not about hitting a particular temp but about giving everything a chance to lubricate and expand before winding the snot out of it.

Only in really hot weather does my oil temp exceed 200 F on my 2009 C2S. Usually it only gets to just below that. ( Stock thermostat and no center radiator - 6 speed manual ) At the track I think it made it up to around 225 F or so in the green run group.
