I'm looking for a link to an engine size calculator (in cc's) that shows all possible combinations of cc's based upon different crank and piston sizes for a Type IV.
I've seen this matrix several times on the web, but can't find it today. |

engine displacement == cylinder displacement * number of cylinders
cylinder displacement == area of cylinder * stroke area of cylinder == pi * r**2 (3.1415926535 * (diameter/2 * diameter/2) eg: 80mm bore, 66mm stroke, 6 cyl radius of bore 40mm r**2 == 1600 * pi == 5026.5 * stroke == 331752 * cylinders == 1990513 that's cubic mm -- divide by 1000 for cc 1990.5 (popularly called 1991cc |

Oops. The Excel file don't download right, so I whacked the post.
The formula is =3.1415*({bore in mm}/10/2)^2*{stroke in mm}A2/10*4 |
