Long Way:
Real 312PB Bore x Stroke = 78.5 mm * 51.5 mm
So....
π x ((1/2)(1/3)(78.5mm))^2 x (1/3)(51.5mm) = 9231.51mm^3 per cylinder
9231.51mm^3 x 12 = 110778.1mm^3
= 110.8cc
Short Way:
2991cc / 27 = 110.8cc

When I first did the official calculation I forgot to square the 1/2 (so I got 444 cc....)
he says on the video being interviewed by Clarkson that it is 100 cc..so the thing may have more than 10 bhp... |
So much time lost for nothing...
