Compression ratio

Post by turboedbug »

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
