Default CR Comparison Graphs

First off, I did do a search but didn't come with what I am looking for.

Question: Can you give me a link to dyno charts comparing 10:1 to 9:1 or give me the link to it? I am trying to show that 10:1 only adds a minimal amount of power over the 9:1's and isn't worth the risk. Thanks guys.

No takers? I'm sure the dyno charts are out there somewhere.

There was a dyno comparison evanstuning.com awhile back. Search for it, I think it was referenced on here too.

That's a good comparison showing the difference at the same boost level, but what it doesn't show and is another good point. Is the fact that if you lower the CR, then increase the boost to have the same cylinder pressure you actually make more power with low CR and high boost vs high CR and low boost. The only thing that the high CR is better for is less lag time.

Perfect! Thank you....that more than backs up my argument that the guy should just go with 9:1 and call it a day.
