Hmmm.... I think your right...

I wonder if it came with different compression ratios throughout the history of the C20LET

My Mahle catalog shows a factory C20LET compression ratio of 8.8:1

I was sure that the C20LET had a 8.5:1 compression ratio.... I even asked Tom and he thought it was 8.5:1 as well.

Strange.... I wonder if there are several different versions of the C20LET out there.
