How do you get cubic inches in a motor?

Answer 1

you take the volume of each cylinder and add them together. the volume is calculated using the bore (width of cylinder) and the stroke (the height of where the piston reached the top [crank angle of 0 degrees] to the bottom [crank angle of 180 degrees]) volume = pi (3.14159) x radius (1/2 bore) squared x height (stroke of the cylinder) that will give you cubic inches per cylinder. Then just multiply by the number of cylinders in the engine.
