A drop from 23.1 to 17.8:1 from just 1.1mm removed?! Wow. I didn't expect such a sensitive drop. I don't think i'm going to do it then, power>reliability!
Do you know how much it dropped to cylinder pressures by though? Do you know if its a linear relationship, or exponential/some sort of complicated non-linear relationship between the 3 variables?
If the expo. It would be interesting to see if theres a sweet spot, to find an acceptable compromise between reduced exh/airflow and decreasec cyl. Pressures and CR drops/reliability..
