I'm assuming the later since you mentionned the plenum was greater than 3.5L yet it still has fairly long runners for low-mid range. That right?

So were there gains?
Looks pretty close to the HOT TopSecret plenum. Make it look slightly more like this one and show gains and you ought to get plenty of business with this.

one suggestion.. make sure the vaccum port on the top right near (where the fuel damper is) does not interfere / extend to this area, some people are running fuel pressure sensors block adapters..

I could care less about looks: if it works it works. My concern is the potential “dead air pockets” marked with an “A.” The air is fed by the big side tubes, then hits the flat wall which I have marked. I would prefer that the outside pipes be smoothed so that they meet the edge of the pipes for the front two cylinders.
Also, a common problem with upper plenums and intake manifolds is the front two cylinders are located the greatest distance from the source. So that these two cylinders are always working with “leftover” air.
One day someone will give us an intake manifold which moves the throttle body to the front of the engine instead of routing the air from the front of the car all the way to the back of the engine.

Then the problem would be reversed, you have to shape the manifold to correct it. Thats why the ends are taperd down at the last two.
I hope to see the bhp numbers soon
and maybe flow numbers sooner or later.
Awsome work Tim.

I got a chance to see this in person on Saturday, that manifold is truly a piece of art. All aluminum and immaculetly welded. Teh runner transitions (that I could see) were great. All around an amazing piece. Tim is one hell of a fabricator no doubt about it.
