Engine Calculator for Four Cylinder VW Engine
Use this VW Engine Calculator (calibrated for a Four Cylinder VW Engine) to check the displacement and other specifications for your engine combo.
Example:
To determine the appropriate head combustion chamber volume needed to build an 1800cc engine with a compression ratio of 8.5:1, with 0.040″ deck height, you would plug in the following numbers:
bore (in mm)=88
stroke (in mm)=74
deck height (in inches)=0.040 (our recommended target deck height)
and desired compression ratio=8.5
Then click the ‘head CC’ button and you’ll be given the answer (which in this case would be 54cc.)
