I have been driving my 911sc in around 50 degree weather and the temp guage barely goes over the white bottom line and doesn't appear to want to get any higher in this weather is this normal?

 

Same as mine.

 

Same, unless you coax the engine into warming up it's just not going to happen. I took mine to a track day early in the spring when it was cold and rainy, and I'd need at least three or four laps at 70% rpm/throttle before it got hot enough to really open up.

 

Same as mine also.
