I made a little comparison video between my best lap and Cory's best lap to see if I could more easily identify spots where I was giving up time.
Here is the video:

From watching this video, a few things stand out:
- I am giving up almost a second each in the two fastest corners - turn 3 and turn 8/9
- Cory is going down to 3rd going into turn 1 and I go down to 4th. He really rockets out of turn 2, partly because he is in 3rd but also he really gets on the gas early and the car is really pushed to track out, where I am still kind of driving out to trackout (not as much but I still am)
- That same thing applies to most of the other corners, he really gets a better exit than me due to carrying more speed and/or more early throttle application.
- Looking at the accelerometer, he is often pulling a sustained .1 G more than me through a corner. On the faster corners, this often equates to higher mid-corner speed. In turn 8/9 at times he is 10 MPH faster than me mid-corner.
From all of this I have several things to work on, and I think I could pick up another 1-1.5 seconds just by doing a few things:
- Carry more speed from the exit of 2 up through 4. How? Shift to 3rd before turn 1, get a better launch out of 2, and build my speed up and don't lift off too much before turn in for 3.
- Carry more speed through 8/9. How? Don't lift off as much, maybe shift from 3->4 a little bit later and then hold maintenance throttle to keep my speed from dropping too much.
Sounds easy, but I have been trying to work on these two corners for a while... It is easy to type it, but hard to keep my foot from lifting off the gas...
If I could pick up even .5 second that would put me down into the 1:27's which would make me about even with my friend Caleb who has a 981 PDK Cayman, I would love to be able to keep up with him
Here is a track map of Roebling Road so you can see the corners I am talking about.
By looking at the track, a lot of folks count 6 corners. I think I heard it has the numbering it does because of corner stations.
Here is another view that shows the radii and some more details about the track and corners. This form has been copied so many times it is barely legible - I would love to find an original copy.
