If so that's impressive. As for the fuel consumption, it's not surprising since air resistance rises roughly with the cube of the speed. Reducing from 55 to 50 drops your air resistance by 25% ! If you slow down more than this, you also have to remember that engines are at their most efficient with the throttle wide open, so the gains are not as large as air resistance alone would lead you to think."</p></div> Mon, 26 May 2008 14:37:53 -0400 diamond geezer http://www.productwiki.com/diamond-geezer/#item-203934 http://www.productwiki.com/diamond-geezer/#item-203933 <div><p><em>May 26, 2008 at 2:29 pm</em></p></div> Mon, 26 May 2008 14:29:32 -0400 diamond geezer http://www.productwiki.com/diamond-geezer/#item-203933
