Great Info!
A 48mm TB flowing 783cfm! Wow, this means for us guys with MAF systems don't need to go to a larger TB since the MAF won't flow more than 658cfm!
Now I know that you cut out the screens in the MAF but did you grind down the fins in it too?

Vader What do you think?

 

you don't need to grind down the fins in the maf. according to articles i have seen that only yields another 20-30 cfm more.

 

Yea, but that is 20 to 30 more cfm! And in these MAF system cars every little bit helps! Right?

 

not really, a 350 wouldn't even need 670 cfm even if you ran it up to 6200 rpm.

 

Awesome! Thanks for that info, MadMax! (Glad to see a 2.8 MAF test in there, too! )
