The Sundog sever looks like its down it may be temporally, so you might try back later.

There is a free one here that you can download. Works fairly well I think. ...

Something I've noticed with the virtual engine calculator is that it reports a lower C/R given the same variables and values as every other one I've used, and by more than .1

I've been using the one at Pat Kelly's website, it will also give you dynamic C/R
