No that calc is only for finding out a specific injectors flow when you raise the fuel pressure above what they are rated at.
Here's a website that publishes the formulas, and a few calculators, just scroll to the bottom http://www.rceng.com/technical.htm
HP in that formula needs to be the max expected flywheel hp, or the max hp you expect your injectors to support.
BSFC should be around .625-.65, I used .6 for my supercharged setup with good results.
Once you figure injector size, the complicated part comes in with fuel pump and line size selection.
