I think that the drivetrain losses aren't a percentage for a given car, 
it's just specified that way for extremely general comparisons between 
cars.  By this I mean if your drivetrain sucks up 30 HP to move down the 
highway at 100 miles per hour (all purely made up numbers!) and you 
increase the available engine power by 100HP, the drivetrain doesn't 
suddenly need an additional 20 HP to go the same 100 miles per hour (if you 
change your tires, or change the gearing, on the other hand, it may require 
more or less power to go the same speed.)  So if your stock engine produces 
200 HP, and you chassis dyno it at 160HP, and then you do some mods, and 
your new chassis dyno power is 350 HP, then your engine is only producing 
390HP (200HP + the difference between dyno reading 1 and dyno reading 2) 
not 437.5 HP (350/0.8=437.5).
