In a hpf or fsr manifold, the air basicly comes in from the front left hand "corner" of the plenum. On that type of design the air doesnt' have to change direction as much on its way into thecylinders. However. On your design the air enters the plenum in a direction not headed towards the cylinders at the front of the car, but still you seem to be the one making the most power.

I don't know if this was a good explanation as i don't have a wide vocabulary.
