Post subject:  Drag Coefficients?
Does anyone have any aero drag coefficients (Cd) and cross-sectional areas for various A-bodies? I'm particularly interested in '64 Valiant four doors, but curious about all of them.

I think the Cd is something like that of a brick............


From my desktop drap program
66 Nova 26.0 sqft Cd 0.40
64 Dodge 28.7 Cd 0.41
69 Camaro 25.0 Cd 0.38
67 Chevelle 28.4 Cd 0.43

I'd say something like the Nova's sqft and depending on body a Cd .40-.43

Its funny how it goes.....its a no brainer that my GF Eagle Talon TSI AWD is .290 Cd....but who would figure my 91Buick Roadmaster Estate wagon would be .33? Honda CRV .45?

Here is a good table http://www.mayfco.com/tbls.htm

The simple explanation of their technical gobbledeguck is wind resistance.

At highway speeds, aerodynamic drag is a big factor in fuel economy. Yes, it's also often the limiting factor on top speed. You can estimate the power required to maintain a speed if you know the drag coefficient and make allowance for rolling resistance.
Of course, then you have to look at the actual torque/power curve of your engine, transmission and rear end gearing, etc. to see if you have the torque to accelerate to and the power to maintain that speed at those RPM's.
It's all to answer the question: "What'll she do?"
