Practically wanted to know which one is correct because the first one is giving me higher numbers than the other with the same info entered in both. use it for yourself and be the judge or if you have knowledge on an engine build enter ur specs in both and see if which one comes up with ur CR or cloest to it and let me know.

the first one has alot of cool stuff and asks for more info than cspeed but i cant get them to even come close to each other with the end result. i usually do the calculations by hand but i know the cspeed one is correct.
endyn
here is the simple but accurate calculator i use.

Where are you seeing differences between the cspeed and zealautowerks compression calculators? I know the cspeed one has never had the correct figures for PCT pistons (as the compression height isn't listed). And they rely on you to know your piston to deck height to get an accurate figure.
The zeal site figures piston to deck height dynamically, so as long as you input your correct parts, the compression ratio given should be fairly accurate.
