I finally got around to overlaying the video from that weekend with the data from my Harry's Laptimer app. I started the session below from the front of the grid in order to avoid traffic. A Whippled Mustang GT with similar other mods (driver harnesses, Vorshlag caster/camber plates, & slick tires) caught up to me by the third lap, and we toured the rest of the field for the remainder of the session.
