Displacement.
Does anbody know a formula for checking displacement.
ie.. piston size (times) stroke (divided by) # of cylinders? Does anyone kow the stroke of a 2.4L??

2.4 used 70.4mm crank
http://www.calweb.com/~thom/engine-types.html Formulas for displacement, bore and stroke pi/4 = 0.7853982 cylinder volume = pi/4 x bore^2 x stroke stroke = displacement / (pi/4 x bore^2 x number of cylinder.

the 2.4 isn't actually 2400cc it's actually 2341cc.

pi x (bore/2)^2 x stroke x # of cylinders = displacement
2.4L stroke =70.4mm and bore =84mm. A 911 engine should have 6 cylinders. But you knew that.
