Do you take turn 16 flat-out? I would see the revs rise slightly as the inside rear tire got light coming through there onto the front straight.
I also had a car spin in front of me on that same front straight and come across and hard into my passenger's side door right at track out. That was ugly.
That track is too tight for my tastes. I've only done endurance racing there, so 2 hours stints, but there's no time to relax and catch your breath.
