The Cylinder Bore Size calculator computes the cylinder bore (diameter) needed based on the total engine volume (displacement), the cylinder stroke length and the number of cylinders.
INSTRUCTIONS: Choose your preferred units and enter the following information:
Cylinder Bore (D): The calculator returns the size of the bore needed bore to achieve the desired displacement (v). The bore size is in inches. However, this can be automatically converted to other units (e.g. centimeters or mils) via the pull-down menu.
The formula for the Cylinder Bore Diameter is:
`D = 2 * sqrt(V / ( PI * S * n) )`
