Dynamic compression ratio calculator

Here is a link to the page where I got my DCR calculator. It has great information on the topic as well.

Good info. I'd often thought of that, but never really looked into it.

To me, that would be about the perfect ratio. Since the ones I've calculated seem to ping at about 8.6-8.7 it gives a little bit of margin. I went with a flat 8.0 on mine and then adjusted for altitude. With any luck I'll be able to go down in altitude a small amount before I ping, but probably no lower that about 4000 feet.
