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 Alistair -- '82 Westy -> diesel converted to gas in '94 albell@uvic.ca http://members.shaw.ca/albell
