let you do the math :) (and don't forget Martin Jagersand's vanagon power
vs. drag plot somewhere on his website

(air density via barometric formula)

rho = rho_0 * (273/T) * e-rho_0*g*HNN/P_0 �

T Air temperature�(reduced to deg. Kelvin) (influences air density)
HNN Height above sea level (influences air density)
rho Air density 
rho_0 Air density on sea level at 0� Celsius (32�F)
P_0 Air pressure on sea level at 0� Celsius (32�F)
g Gravitational acceleration
