[W126 Coupe] question for dan landiss

[Shayegan, Richard]

Dan,
   In your topspeed excel spreadsheet, where did you get your frontal
area data? I've seen different numbers online (online I see 22.59 and
you have 24.7). BTW, using the frontal area I have for an SE (23.13)
your excel sheet matches my 380SE's real life specs almost exactly (top
speed for 155 crank hp in your excel sheet is 121 and I got 125, which
can be explained away by temperature, and also my gtimer says I get 132
rear wheel hp so calculating based on that gets 123.5 on the excel
sheet, and at that point speedo error is larger than the difference).
That's some good work you did there.
Richard
