by adding a victor x intake mani, how much would that change the a/f ratio. say it was 11.5a/f before the manifold change. thanks.

 

None. it is irrelevant to the air/fuel ratio.

 

What paramaters does it change in the tune? I figured with the more air it brings in, it would change a/f.

 

hmm interesting. i also would have figured that adding the victorx will help the motor breathe better, and consequently lean the afr because now more air and the same amout of fuel.

i noticed a change in afr a few years ago for example going from a gsr cam to a b16 cam on a mid 300hp setup. afr richened up around 2 or 3 tenths because the motor wasnt flowing as much air decreasing i thought.

is it irrelevant to afr just because it would cause a small increase in the motors ability to flow air??
