A smoother transition from the diffuser to that low pressure area would probably be helpful.
But, like I said, it just *looks* like it would work well.

So basically your saying that there is a low pressure area behind the spoiler, and to make the low pressure area behind the spoiler to have more downforce, you try to feed low pressure (high velocity) air from the bottom channel of the diffuser of the car, to the top.
So in order to make this downforce by.....how? because the way i see it..the low pressure area is already making the most downforce, and feeding it any sort of air perpendicularity especially high speed air will make it no longer a low pressure zone, but normalized atmosphere.
but you talk about reducing drag behind the trunk area using a smooth transition from the diffuser..then...exactly how was I incorrect when i said, the reason why the center diff channel feeds upwards was to divert "to the area that greatly suffers from wake (turbulance) and vacuum (drag) which is directly behind the trunk and centerline of the vehicle"
sounds like we are talking about the same dam thing
