I run a much smaller wing. He's still far faster than I am.
The official Cd of the s2k isn't published, but the math works out to be about 0.38-0.39 with the top up
Cd matters.
Non-existant aerodynamics? Have you seen the latest round of exotics? There's an insane amount of simulation that goes into these things. Top rally and race cars have horrible Cd and frontal area because they're made for extreme downforce, not to cut through the air with as little resistance as possible.

i'm not arguing that you're wrong, but don't you think that are a lot of other variables to take into account?
tires, suspension, driver skill, engine conditoin, etc, etc.
you're not isolating the aero parts as the only variable that can affect those exit speeds.
