Reference video of another driver doing a 2:22.44 Sebring lap in a stock SS 1LE in about the same ambient temperature I had - the fastest I've seen (automatic transmission; I guess a manual would probably be at least a second slower). Unfortunately this lap was set after my trip so I didn't have it to reference beforehand: https://www.youtube.com/watch?v=JkTn1gJkHQw

Sebring with PBOC driving solo in the instructed student group on Sunday 5/8/2022, second session that started at 11am. Not bad for being only my 3rd ever dry session at Sebring (thanks to a big thunderstorm on Saturday), but there is still more in it and I badly missed the apex of turn 7. This remains the most intense session I've ever driven at any track! I think that was probably because I was pushing hard before I had done enough laps to develop consistency at this track plus this was my 4th day driving on track in a row (with 2 days at Daytona immediately before this...not recommended but I'm thankful I got to drive both tracks on the same trip).

Going flat through turn 14 (Bishop's Bend) at 120+mph is exhilarating! That is the main reason I used PTM Race instead of turning everything fully off. The track was less bumpy than I expected based on what I'd read/heard (except for turn 17), maybe because my home track MSR Houston is quite bumpy.

Note: I moved the start/finish line in Cosworth Toolbox to avoid a big slide I had in turn 17 (video: https://www.youtube.com/watch?v=hnMXz6dMVpY) at the end of this lap (my personal best until that point) which cost me a lot of lap time; the full lap at the normal start/finish was 2:28.31 with the slide. The start of this video was the end of a cooldown lap, so I was going about 8mph slower into turn 17 than the same point in my 2nd best lap of the session using the normal start/finish (2:28.35) but I probably entered turn 17 about 2mph too fast to avoid pushing wide of my intended line at the end so I think it kind of balances out.

Unfortunately PBOC ceased operations in 2024, but they were a good group when I drove with them here and at Road America.

For the 3rd session after lunch it was getting hotter and I bailed out of my attempt to carry more speed into turn 1 on my first hot lap to avoid possibly going 2 wheels off on exit under full throttle (video: ). I think my improvements during the session were outweighed by the extra heat reducing tire grip and horsepower. I had a mechanical problem with my car right before the 4th/final session so I didn't get to drive in it but I suspect the heat would have prevented me from going faster anyways.
