We live in different regions with an enormous variety of temperature and humidity combinations . I'm trying to figure oit what is the best climate to run the beast.

I notice that hot and humid does not fare well at all .
I've never driven mine below the mid 50's and clear (South Florida ) .
I tend to notice that mid 60's and clear seems to work best with the sun down and low humidity . But low for Florida is not the same as a dry climate . Altitude also can play a factor.

So what weather adds spice to the ride for you guys ?

 

Hey Larry, I can't relate to your heat and humidity, but ANY weather is good for me to take out my beast. I love driving in any and all weather (except snow and ice). I can say that I have been getting alot of road time in the rain here in the Northwest - but the car handles great with the awd. The perfect day is 70 degrees and sunny.

I can't speak to car performance in different weather because I don't get to take enough long drives beside commuting to work to notice it to that detail. I just smile every time I get behind the wheel - it is my happy place no matter what the weather.

 

its all about density...the cooler and heavier (dense) the air is the better your turbo will push..

add....you might talk to your mechanic...in a warm climate a more efficient intercooler can give you additional power if the stock one is not as good

 

Lots of days here in the Pacific Northwest with temperatures in the mid to high 30's and humidity around 90%. But, don't bother moving here, because you won't like the rain. I really notice a difference in power on the dry side of the state on a hot day.

 

Upper 30's and rain ? yikes .
We get some rain here too but on those days I try to keep my Turbo indoors . Gtreta 70 and sunny is somewhat close to the 65 and sunny I was thinking of . It's just cold enough to keep the AC or heat off and retain cabin comfort giving full juice to the engine.

Keep in mimd I have not taken the car under the 50's and am curious about it. I have not driven in ultra dry or high alttitude either. I have seen many videos of Porsche road tests in extreme climate yet nowhere in the manual does it specify an ideal temp amongst all the data specs .

 

My TT loves the below freezing temps in Canada. It's like another 50HP! However,the cold roads require some caution. I agree with the comment about intercoolers. When you drive in this kind of cold weather you really get an idea about the impact of cooler air for the turbos. It's all good if your driving in any weather!

 

Yes, the cold is great, but with summer tires, which lose their grip below 45 degrees, I don't drive much around here, since we don't see a lot of days with warm temperatures. I haven't noticed a drop off in power at altitudes up to 6000 ft. Perhaps that's due to the fuel injection's ability to compensate.

I recall my Toyota Tacoma with a supercharger never ran out breath at altitudes up to 11,000 feet (in Colorado) much to the consternation of the local rednecks in their F150's and Silverado's.

 

9 degrees fahrenheit and winter tires!

 

Cold/dense makes intuitive sense, and cold is definitely better than warm.

However, on the density point, I found that my car pulled very very hard in cold weather at high altitude (about 4500 feet).

Someone explained to me (maybe they were guessing or BS'ing me) that altitude favors Turbos since you can "make your own atmosphere" by compressing air with turbo (hense density) but you have less wind resistance.

So, I would say Denver in winter is you best bet.

 

50's at sea level.

 

This raises questions as the answers are so varied :

1) Why hasn't Porsche placed their test data figure to specify an ideal climate right on the manual?

2) Humidity --even in cold has to play a role . For instance if I stand in 50 degree temp in a dry region it is not the same bone chilling 50 of the Florida peninsula . Do multiple conditions interact in combination to create a ideal run?

3) There's a lot of fast cars in Florida . The Texas mile also takes place in a region where climate may not be ideal . Why not select have a record breaking event where the conditions provide a fast run ?

 

fact is...whatever the conditions are on a particular day and time...they are the same for everyone...so not an issue at an event...for a record run..dense air also provides more air resistance (read drag) so the added hp is usually offset by more drag...everything is a balance and a compromise

 

The conditions are the same (agreed) but since the cars are different car A might beat car B under a different set of equal conditions .
My guess is that the manufacturer (with its enormous testing abilites) might have enough test data to even specify a specific region, climate, altitude --factors which comprise optimum "density" suited for the best time of a 997tt .

I wonder where it would be .

 

the guy is right car act so bad in humid and hot weather very slow ...

 

Winter temperatures with snow tires and this car is killer. I'm headed to VT weekend of the 20th to get some time in the snow and slush. Am totally looking forward to it and will post some pics.
