Compression ratio will be increased at the rod/piston connection: the wrist pin. Since these wrist pins have a smaller overall diameter, this allows us to offset the hole in the wrist pin bushing. This bring the piston further up, reducing the volume of the combustion chamber. The target is 12.5:1.
