I’ve been comparing Summits CR calculator to several others including Wallace racing and Diamond pistons website. They are almost .75 in cr higher than other sites. Anyone notice that? Maybe CYA?
with only a few things to factor I think they have it set up for higher results so it's more of "Max" # , and not a exact # that way the novice builder errors on the high side...let be honest if you build engines for a living your not using that calculator......I use it to bench race and get a vague idea.
