Boost calculator?

[Xtant]

I realize that depending on your particular setup levels of boost can change. However is there a general idea for what pulley combination yeids what output on a typical motor? I'm just curious what a 3"/6.87" combo will put out on a S-Trim on a 302 block with good intake/heads/etc
