Not going to be cheap but if it's from Cosworth, it's one of the few manufactuers I actually believe.
I wouldn't confuse this with the blangity SSV plenum. Much more engineering went into this one from what I see.

I wish there was a side pic. I can't see how the air being taken in goes into the runners for the cylinders. I mean, are those velocity stack tube thingies where the cylinders will draw the air in or are they connected to the TB and provide the air source? Looks hot though and it sounds like it'll let the VQ keep up the torque at the higher rpms and thus have a better top end.
The intake looks to be at the rear. Those are velocity stacks which will suck in air from the main chamber once you put that cover back on (the cover is only on on one side in the pic). Looks like they were trying to balance the intake runner flow much like the stock plenum and unlike the straight in SSV.

Air gets taken in though the TB, around the velocity stacks and finally in/down the stack into the lower manifold and heads. Sorta like the BMW M5 intake manifold.

LOL well sure. Anyone in their right mind would want to see some data. I don't know how so many ended up buying that SSV manifold without the same. 
IMHO, this unit is much more thought out than others offered. And from the looks of it, it seems to be designed around a naturally aspirated engine vs a FI application. (much harder to do IMHO).
I'd say this is much better step in the right direction vs others I've seen. But it wont' be cheap. Might as well get that out there right now. They've already spent alot of $ in a casting mod etc.. and clearly have played around with diff stack lengths if they want to offer them adjustable. ie... long = lowend and short = topend.

Yep, damn sexy. Cosworth is well known for making the best. I certain it will perform as advertized. Right now, we just don't know the purpose of the manifold.
Interesting note, the volume shrinks towards the front, just like the stocker.

This should compliment their heads well.
I read (and passed along) a rumor a good while back that Cosworth had been doing development work on the VQ35. Glad to see it wasn't just heads, pistons and rods.
Also makes me wonder if Cosworth built the (alleged) 420HP NA VQ35 in the recent Renault concept.
