I saw Dieters partner today, nice guy, picked his brain for about 40 Minutes. Bought some piston rings. I posed the question "dome volume on my 2.5L" he pulled out a notebook w the info. 19.38 cc, same as my measurement. Mahle does exaggerate their CR. They came up w the same CR that i did 9.8:1 on their 10.5:1 pistons. apparantley the Cr changes when the engine is hot. MMMMMMMMMMMMm
