Compressor maps?

Hey, I am trying to read some compressor maps. Does anyone have an estimated of how much air a 3rd gen engine is moving. Also what kind of HP n/a should we be putting down?

My motor is street ported.

Thanks in advance.

Also,
When you calculate the displacement of a 13b, is that 1.3 liter's per rotor face? Would that mean a 13b is techincally a 3.9liter? But, the eccentric shaft turns three times for every combustion cycle. I am confused on how displacement is calculated for our engines. What amount of cubic inch's should I use to calculate the the volume of air? 79.3 seems way to low for calculations.

I was in a debate with a guy who builds pistons engines about the displacement of our cars. he swears they are a 3.9 liter. Anyone care to share some knowledge?

13B works like a 2.6l piston engine.

Here's a page on calculating stuff like this...

Either use 2.6 for the size of the engine OR do not divide by two in the first equation...
