Help with compression ratio
I posted this thread with the technical forum but am not getting any response. I hope that I can do better here. I have a set of P & C's with cast iron barrels and what looks like Mahle pistons. They are for a 2.0 L engine but I have no idea what the compression ratio would be or what engine they would go to. The marks on the piston head are Sp0,03 On the flycut 79.9 which I would assume is the piston size. Inside the piston 80S184 and a 51 over a 2 in a circle. Can anyone help.
Thanks in Advance. Rick

The number doesnt work for the ID but visually they are late 60s 2.0 T pistons @ 8.6 CR especially with the cast iron cylinders.
The 2.0L is 9.0 CR 80V65 is the inside number for the L pistons Bruce |
