i know all of that but what is the difference between 11:5:1 and 9:1? i know its like 900cc's of air sucked in at the bottem of the rotation and 90cc's at the top of the combustion but is 14:1 better then 12.5:1? and what C/R is in bikes and formula cars that causes them to be able to go over 10,000 rpms?
