Back in the day, oversquare was the recipe for power. More rpm at equal piston speed, room for bigger valves. These days, they talk about undersquare being the recipe for low emissions and high efficiency, less distance for the flame front to travel and less metal area exposed to combustion gasses and piston ring friction. _______________________________________ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
