Compression test done on my Alaniz Motor
Since my Motor is up and running now I decided to get a compression test done when I switched out my plugs and regapped them.
Now I know that a N/A healthy F20 has a CR (11.0:1) and yeilds compression test numbers of around 220-240,
My CR was suppose to be around 9.8:1 according to the conversation with Joe Alaniz prior to the build - My Compression test yeilded numbers between 166-171 through the four cylinders and the mechanic says he was happy with those numbers.
Logic tells me that with a lowered compression engine you will see lower compression test numbers but can you calculate the actual Compression Ratio of your motor assuming it is healthy? In other words, I would like to know if these numbers are consistent with other lower compression motors?
Thanks in advance

Agreed, I have a decent consistency in all four cylinders I am just wondering if the actual Compression Ratio can be calculated?
Thanks for posting
I am also trying to see what numbers other lowered compression motor owners are seeing on compression tests!
