Default Building a CAI

Ok I know there's several threads on the CAI but this one is a little different.
Instead of buying one of these packaged deals I'm thinking about building my own.
For a couple of reasons.
One is price. I can't see spending 300 bucks for a plastic tube, plastic box and a filter.
Also I want to get more airflow than the car can possibly need.
AND
I can't seem to find CFM numbers for any of the CAIs on the market.
I have found a few links that calculate the needed CFM for engines according to displacement and build. A full race 5.7 would need 668 according to this calculator or 766 to 957 cfm according to this one.
I'm not planning on going full race but I still want this kind of flow.
I'm looking at running an Amsoil filter. I have an email to them requesting a CFM chart for all of their filters.
If anyone knows the CFM of the multiple different systems for our cars please post them.
As soon as I get the CFMs from Amsoil I will post that as well.
Once I get it built I'll post pics and a materials list of everything needed to build this system.
Below are some links to the Amsoil filters.

I'm considering the EaAU4091 filter.
It's an oval with an offset flange. As big as it is I would expect it to give way more airflow than we could possibly need.
