Effective displacement on boost?? - HybridZ

this page also has a broken link to the much more accurate formula, it used to work when i originally favorited the page, but it included everything from barometric readings for atmospheric pressure to efficiency etc.

but the short and thin of it is, 14.7 psi=1 bar= x2 the displacement....at 100% efficiency.

EDIT: (14.7 + boost pressure)/14.7 = "turbo muliplier"
