Go see my web site. I think there is a coastdown method there. What you get
is an overall drag coefficient. Need stop watch and just some reasonably
flat track. Accel to maybe a 100 then coast down to 80 or so. Need to know
speed at start and end (IIRC).. I think we just about beat this to death
some time ago.
