More cooling data: Car is running at 95C. Ambient is 72F.
Spikes at 98C at stop lights.
Needle is straight up, of course.
Car history:
85k currently.
Temp sender replaced with 059919501A (Green top?) 8/04 at 55k miles.
Timing belt, water pump, coolant flush in 2/05 with 62k miles. I think he used a plastic impeller pump. This is also when I started tracking the car. If I think back, I *think* I first noted elevated temps on the track in summer 05.
OEM Thermostat replacement 1/07.
Last Sunday, the needle didn't go up when the ambient temp was 60-68 deg F. Once the ambient temp rose above 70, then I noticed the temp wandering up a notch for part of each lap. After the ambient was above 75, the gauge was staying near 1 notch up.
Is it possible I just have a bad temp sensor?

my car runs >>>
regularly between 93 and 96....i have on occassion seen 100C but it does not stay there long. I can get it into the 80's if RPM's are up, and going down a hill....but it quickly comes back to the low to mid 90's. This translates on the scangauge to a 191F-198F on average....which is very reasonable IMO.
There are subtle differences with each car, and your numbers do not look high to me...some 180's run a bit cooler...but not much.
If it is running good....i would leave it alone....you are not gonna overheat the car at the track. Remember, as you collect more data, it may "appear" to be a problem, but it is actually normal....i call it the TMI syndrome...;-)

My needle will tick up on "spirited drives" when I come to a stop or a lower speed section,
especially after being on boost heavily. If you have a front mount, that is really just a heat sink, so after boosting for a while it will be pretty hot. That heat will dump in to the radiator for a few minutes of NOT being on boost. After that time, it should come back down. If you get up one tick, I would not be worried at all. If you get over one tick, and in to the red, I would be worried. If you have not yet, adding an oil cooler will help those temps, as the oil and radiator share cooling in the OEM setup. Plus you could/should also add an oil temp gauge then, as proper oil temps should be reached prior to using much boost.

What's the best solution for an oil cooler?
I only push the car hard on the track, and only after a good warmup. I drive like grandma on the street.
No FMIC for me. My VTDA will be delivered today.
