I was just wondering if the EF I6 throttle body can be bored and if so to what size i've heard a mil or so isnt really worth worrying about, also if anybody knows how much cfm they flow at stock...
Cheers

Why bother?
V8 guys are pulling 250RWKW with 65-70mm throttle bodies, NA. You'll just lose throttle response and reduce air velocity.

(thats why i wanna know the flow bro) I cant quote on the ford product, but this will give you an idea (based on accufab mustang TB's) 65mm - 664CFM 70mm - 787CFM 75mm - 924CFM What size are the EF/EL 4L TB's? 76mm?

63 mm are ef throttle bodies you cna only bore them out to 68mm or else they will become to weak and collapse specially under boost

Hmm. Wonder where I got 76mm from. LOL
I dont think the extra 3mm is worth it considering potential flow from the accufab figures I posted up.
