2. Calculate the Compression Ratio:

Repeated presses of
starting with the entered Bore.
The calculated compression ratio is about 8.81:1. At this point, if
you were not satisfied with this ratio, you can use your Hot Rod
Calc to play out some other scenarios.
For this example, to raise your compression ratio, you could enter
a thinner Head Gasket Thickness of 0.015. All the other inputs are
in your calculator's memory.
