I think what you're looking for is in "includes/functions_reputation.php"

look for

 else
 {
  $reputationgif = 'pos';
  $reputationhighgif = 'highpos';
 }
 if ($reputation_value > 500)
 {  // bright green bars take 200 pts not the normal 100
  $reputation_value = ($reputation_value - ($reputation_value - 500)) + (($reputation_value - 500) / 2);
 }
 $reputationbars = intval($reputation_value / 100000); // award 1 reputation bar for every 100 points
 if ($reputationbars > 10)
 {
  $reputationbars = 20;
 }

Of course yours will look a little different but play around in there until you have it the way you like it.
