If you are building heat on a highway pull something in the turbo system has lost efficiency, either the turbo itself, intercooler, etc.??
If all is working well together, your IAT's should drop during a pull.

Many factors come into play here.
ambient temperature for one is a big factor, also delta time the compressor is actually pumping out 200+ degrees.
The faster u go, the more time the compressor is pumping out hot air. 3rd gear pulls take a lot less time than 5th gear pulls.
140 degrees after a long sprint is not uncommon for florida weather.

Sounds like something in your setup is out of its efficiency range. Could be a badly placed intake, an over spun turbocharger, a improperly designed/sized intercooler, or some part of your aero package that is preventing proper cooling. How does your coolant temps look during all of this? Have you logged them in relation to your IAT's?
Since i relocated my air filter into the fender, my air temps dropped 20-30 degrees compared to when the filter was located inside the engine bay. An interesting fact i just learned from being N/A for the past few weeks is that my intake system really worked! i just threw a filter arm onto my TB while im N/A, and the IAT's both at stopped and moving speeds have increased about 40 degrees compared to how they were with my cold air intake with the turbo.

Do you have pics of how you routed your intake?

Intercooler is a Precision 600, I don't think that's the issue. I'm leaning towards Elroy's suggestion of the intake location. I've already melted a filter where it is right now.
Plan on venting the hood either this week or next among a few other upgrades.

1. CAI
2. Hood ventilation
3. HPC of manifold and turbo casing.
My S has VERY little heat under the hood even after my weekly morning crossing of Bay Side Bridge deep into the digits... I will pull a log (IATs) for you next week and maybe Thursday dinner
IF I EVER make it to another one

#2 is happening soon
#1 - maybe. Don't have a lot of room to route a pipe and mount a filter right now
But hey Elroy, you've got that pussy SC on your car. Real FI makes heat!!!!!!!!!! lol
Who knows if they'll be another meet? I got left out in the cold by myself last week @ QSL
