Compression ratio
Posted: Mon Jan 28, 2019 4:56 pm
Hey everyone. I am going through some math here and would like a second set of eyes to verify what i have going on.
Now this isnt vw but the math should be the same
At tdc i verified the total volume at 25cc
The combustion chamber of my heads is 49.5 volume
So combined volume of 74.5
head gasket .6 gasket bore 100
Piston bore 99.5
Stroke 79.
When i punch these numbers in i get 8.7 to 1
Does this sound right? Its been quite a few years since i have calculated a comp ratio
