hi. i was just wondering how does it work? can you cange the displacement just by changing the crank shaft?

(B/2)²*pi*S B=Bore, S=stroke.
(8.1/2)²*pi*7.7= 397.78*4 (for 4 cylinders)= 1587cc

how are you getting the rod to stroke ratio?

why do you represent bore as 8.1 and stroke as 7.7?

Centimeters... since we calculate displacement as cubic centimeters, not cubic millimeters. It's just easier to start with the right measurement scale than try to convert it later and get confuzzled.
