Point taken about the other factors such as timing and chain tension, that alone makes me not want to go this route...
But to beat a dead horse, I understand that would simply using the equation for cr
{[l•(πr²)]÷cr} : {l•(πr²)}
making it:
{[94•(π47²)]÷8.5} = 76745mm² or 76.75cc
I realize now I asked the wrong question, not what the displacement of the combustion chamber is, but rather the differential equation on reducing the chamber from the bottom up.
Which I am getting the idea isn't known outside of Suzuki engineering.
For if one simply uses the equation of a hemisphere the calculation is off as one can see below, the chamber isn't nearly a true partial hemisphere.
(disclaimer not my pic, sorry if its yours)
I just figured someone had to know becuase if the ratio out there for the wiseco domed piston of 10.5 is accurate, then the actual differential equation for the chamber has to be known, as well as the deck height (ie the height within the cylinder that TDC extends to)
I'm just not aware of another way for this number to be accurate without someone using the proper calculation, or doing the liquid measurement.
Thus must I then conclude that the ratio stated for the domed piston of is just a ballpark estimate as well?
here is a interesting article that address the problem:
