V2's vs V3's. Flow?

[DwnSouth]

now why would the 3's have a smaller opening than the 2's. Appears the small amount of material on the insert in the 3's can't be ported very much.... What do u guys do?

I believe this is what you are looking for.

I don't really know, but my guess is velocity. I'm thinking the smaller opening is to speed up air flow, giving a slight over filling, or positive pressure VS static atmosphere pressure that the larger opening will give you.

 

I may be way off though.

velocity was my guess too.

You can buy the retainers from FAST to open up the inlet of the VF3's. I believe you just modify the reeds your self. When I got my new intakes for my 35's I was told to match the inlet to the intake by using a dremel.

That's why i'm a member here. Lots of useless info... And sometimes good stuff too!

check how well the manifold matches to the insert. i think your biggest concearn is if the insert hole is smaller than the manifold hole. i know the v3 dont match up for shit on some models. had to demel my cr500 v3
