Another max compression ratio w/pump gas

I think you guys are forgetting a very important part of "max" compression ratio.

What is your altitude?

You list your location as Utah. Mean elevation in Utah is 6,100 feet.

So your dynamic compression ratio IS 8.52 (with 15 degrees added to cam card, as others mentioned) but that is calculated AT sea level. Add 6,000 feet?

Your DCR is now 7.32.

Do NOT forget all the factors when trying to figure out this stuff. That's how you end up with a dog.
