How good is an Evo IC?

Title pretty much sums it up. Anybody know how much CFM or how much HP you can make with an EVO 8 FMIC, they look pretty decent and would fit rather well in the front of my shadow.

I know they fit pretty well in the front of a Shelby Charger. A lot of the Evo guys keep their stock IC's, I figure they must work pretty well. I can't find anything on the internet though.
