To figure Static compression ratio's

[1Gary]

How to figure static compression ratio. There are 5 values which must be used.
1. volume in the cylinder expressed in cc's
2. volume in the combustion chamber expressed in cc's
3. volume in the piston crown expressed in cc's
4. volume in the head gasket expressed in cc's
5. volume in the piston deck height expressed in cc's.
First, you add all the volumes together. Let's say we have 727, 64, 6, 8 and 3 for a total of 808 cc's. Now, removing the cylinder cc's of 727, we add the remaining volumes and find 81 cc's. Now, if we divide 808 by 81, we find a 9.975:1 static compression ratio. Cubic inches can be converted to cubic centimeters by multiplying times 16.387
