Erik;

Those numbers sound on the high side, but very good, since they're within 8 points out of almost 200 (a mere 4%). I would be happy in your case, also, that you are able to keep your pinging under control. I don't have a correlation of pressure to CR (and comparing the actual to straight calculations would be subject to a lot of variables), but I would estimate around 10.5:1...maybe someone with a tight new engine (who knows the CR), can make a measurement and confirm...

Cheers
