Bill...lots of good data and info here. Keep up the testing for the rest of us. I'll be on that secret testing soon.
Meanwhile, being one of the few with a stock airbox I'd like to add comments. Please remember, this is not applicable for a S1 airbox thought.
I've speculated that my gutted airbox sealed to my headlight area does so well because IAT temps are a little lower and slower to climb than your bare pipe temps and a little higher spread than the new insulation at shutdown after 5min.
Another topic though is the tube between airbox and intake for me....another topic though
The engineers clearly designed the 96+ air intakes with your findings in mind.
