Here are the equations
you can use to calculate
compression ratio,
compression distance,
and engine cubic inches:*
Compression
Distance
| 1. |
You will need these
values to calculate compression distance: rod length (inches),
stroke (inches), finished block height (inches), and deck size
(inches), head gasket thickness (inches). |
| 2. |
In the following equation,
plug in rod length, stroke, finished block
height, and deck:
| Compression
Distance = block - stroke/2
- rod - deck |
|
Compression
Ratio
| 1. |
You will need these
values to calculate compression ration: bore (inches), stroke
(inches), cylinder head (cc), deck size (inches), head gasket
thickness (inches), and piston net volume (cc). |
| 2. |
Calculate X
as follows:
|
| 3. |
In the following equation,
plug in X, stroke, head,
deck, gasket thickness, and piston net
volume:
| Compression
Ratio = 1 + |
stroke*X |
|
| head/16.39
+ gasket*X - deck*X - piston/16.39 |
|
Engine Cubic
Inches
| 1. |
You will need these
values to calculate compression distance: bore (inches), stroke
(inches), and the number of engine cylinders. |
| 2. |
In the
following equation, plug in bore, stroke, and
the number of engine cylinders:
| Engine
Cubic Inches = 0.7854*cylinders*stroke*bore*bore |

*NOTE: This
site can calculate these values for you automatically if you
use a Java- and JavaScript/JScript-capable browser with Java
and JavaScript/JScript support turned on. The use of the latest
released (non-beta) version of Microsoft
Internet Explorer or Netscape Navigator is very strongly recommended due to ongoing
security and technical improvements in the Java virtual machines
and JavaScript/JScript interpreters in these browsers.
