Throttle body CFM

Hi. I'm new to this. Ford Racing suggested I try this venue. Does anyone KNOW what the CFM is of the Ford/Lincoln 75mm throttle body used on the Expedition/Navigator 5.4?

Welcome to the forums, you may want to check the performance sub-forums down below, but if I remember correctly its capable of flowing somewhere in the neighborhood of ~800cfm, but then again i think that was for an aftermarket unit. Whatcha buildin?

Throttle body CFM

Thanks for the input. Got a new 2011 Navigator, and always think things can be made better. Magnaflow has a cat-back they say adds 17 horsepower, and looking at cold air systems, one had a nice synthetic media filter that only flows some 500+ CFM and I surely think a 75mm throttle body would flow more than that. Plus I may do a chip, etc, so I need to make sure that any filter will flow at least as much as the throttle body. Not a big fan K&N's as they flow but don't filter small stuff.
