Inside the stock LS1 intake, there are 3 center posts which connect between the floor and ceiling. I'm wondering if removing these will create additional air flow or will it cause an imbalance of flow between cylinders? These 3 posts don't appear to have any real function, save to create a little rigidity within the manifold. Any opinions/experiences? If they can be removed for additional airflow, is there a way to open up the manifold for easy removal? Thanks, gMAG

Many people have cut apart a stock intake trying to find a little extra HP. So far no one has been successful. Remember the stock ZO6 intake is good for some pretty large HP numbers.

WWU; Thanks. Looking inside of that baby makes me want to separate it, reshape the rear wall toward the back two cylinders, and eliminate any corners (AND remove the posts).
With such a great engine, I can't figure out why a comparable intake took so long to be created.

I bet it would fold up like a beer can first time you drove it.

First time over 20" of vacuum is produced it would deform, or possibly crack. You figure with that much vacuum you have the equiv (a guess on my part) of about 20 lbs per Sq In of pressure pushing at the manifold. I believe Dave is right.

Guys, I would be ADDING material inside to change airflow direction, not removing material. If the 3 existing posts are only there to provide support, they could be replaced with more of an airfoil design.
Thanks for saving Mr. Science (me) from the crumpled beer can effect. I was just conjuring up a ready excuse to those who might witness such an event. "That's right, my exhaust is SOOO powerful, that it sucked in the manifold!"
