Re: new australian intake manifold for the 4g63
That paints a clearer picture for me. And I understand why they would want a velocity stack, since the port can pull air from a larger area. But why create turbulance. The velocity stack "compresses (for lack of a better term)" air from a larger area while the stack pulls it in. Why "rough up" the air? Why not streamline it so that it flows better/evenly? The more air you pull in, the better. So why slow the air down in the plenum for it to just wait? I've got gas to burn, let's move it.
