Can someone tell me what the standard compression ratio for a twin port 1600 type one engine is?

If you mean the models sold in Australia, they were 7.5:1 The current beetles come with 6.5:1 for US and 6.6:1 for the rest of the world.

From memory, the book says 80. For a bit of performance 120 is nice, but 100+ with less than 20 between the lot shoud be a sign a rebuild is not quite required yet.

The main object is to find if there ia any differance in the compression figures they need to be equal or with in a few Lb either way.

You dont want one cyclinder with a drastic different pressure

From memory the last time i did my 1500 engine the reading was around 150Lb
I read it on FACEBOOK so it must be true
