It looks from the picture, that because of the angle, the throttle body points more directly at two runners, which are slightly further away. See your second picture above. It would be interesting to see a flow test for to see how much each runner is getting.

I know. The offset angled orientation of the throttle body axis in the original plenum was even more offset than the one I'm building. So I softened it slightly. If it wasn't an issue for Toyota, it isn't for me. I think it was done just to get the throttle body pointing slightly upwards to line up with the stock air filter box, so I did the same thing so as to line up with mine.





This is the original manifold throttle body axis orientation.



And this is the tooter et throttle body orientation.



This is why I don't believe that it was ever an issue. First because the flow is so direct, and second the runners are pulling from the plenum That's what I like most about this particular design. It completely eliminates the 90 degree "kink" runner to throttle body axis orientation found in all of the other typical plenum designs.

Not yet.
Right now, the CNC machinist is making a base plate to connect the hemisphere to the intake runners. After that, I make the 3 tubing fittings, everything gets welded up and then I get to drive it.

The machine shop at Origin Designs made two more flanges. Their work is impeccable...



Also got a Corolla manifold to build into another tooter.
