I did some testing to try and get some data for Cd and Crr. Using the instructables excel document and testing procedure I recorded a gps speedometer and used that to enter the data. Weather was 40F and wind was 3-5 mph. Road was freshly paved.
The only place I found the frontal area was here:

Which lists it as 1.88 m^2 (and a stock Cd of .34). Using that data and the data from the recording I get a Cd of .3024 (11.1% reduction

) and a Crr of .01285
If I put these #'s into the fuel consumption calculator under tools it says I should get 42 mpg @ 55 which is really close to what the Mpguino was displaying (~43)
Also my tank is leaking again. I am going to wait until the semester is over (2 weeks) and then change the tank out with a new one. Until then I will have to just use the mpguino as a reference instead of actual data.
I am currently in the testing phase of deleting the side view mirrors, will post pictures when I am satisfied with the results.
