It's now like the crappy ones found in American cars. If the car's not overheating, that needle in your 987 will not show any fluctuation at all.

Mark and I have checked this out on his 987 at the track when he's been absolutely brutal to the motor on the track and that needle should have moved a little and it does not move past the operating temp reading it is programmed to display.

The 986's have a temp gauge that moves around when you drive the car, hence all the guys freaking out because they've never owned a car with a fully operational temp gauge before.
