So, I haven't gotten to any technical stuff, but in this lap----10 laps into the session at 76ºF air temps, the engine just does not pull the way it does when it's on its first lap at 52ºF.

According to the AIM, my max GPS speed on the back straight for the whole weekend was 157.3mph. I'll give you one guess when I did that. Anyway, that's quite a bit higher than the 149mph in the video.
