Message: [QUOTE="Charles, post: 262129, member: 103"] A 37% increase to total area requires a [i]very[/i] small increase to section width for each piston. Remember, area goes up with the [i]square[/i] of the radius... 0.4375 to 0.4687 would represent an increase in cross-sectional area of ~15% per piston. With 7 pistons, that would more than double pump outflow. About [i]105%[/i] in fact. A little more than [i]two[/i] stock pumps if you went that big. Needless to say then, a 37% total increase in pump displacement would require a VERY small increase in piston area. In fact, just 5.28% per piston. Starting with a 0.4375" piston, it would require an increase to 0.4482". About 0.010 to 0.011 larger pistons. Doesn't seem crazy at all. [/QUOTE]
