I believe the evidence is there to. From my understanding it would be wiser to extend the cover all the way back to the outlet instead of having an open area of 30cm or so if they wanted to keep the higher velocity air at a higher rate, rather then it interfering with the outside air. Air usually wants to even out pressure differences rather fast, hence we can create lift and downforce from aerofoils.
I don't see air accelerating inside the sidepods either.
There IS a tube/cover that extends into the crash structure that's been postulated to exit out that opening in the back near the light. Look back a few pages and you'll see the image. It's been mentioned in passing on/off for the last week.

Yes there is a tube above it. I asked Scarbs would this be possible and he said yes, he was thinking about what that tube was being used for today. I saw the opening the day and mentioned it, then saw MazdaBoy's pic. I mentioned it somewhere else and one person claimed it's impossible. However Scarbs is saying different. I don't know either way. But it sure is clever if so.
What's everyones technical opinion?

When people claim something is impossible, I always find it's useful to ask what they things stops it from being possible. I see no reason why this shouldn't work, but someone may have spied something interesting.

Right, although some pictures have the hole others don't. I would only point to the tube coming out from under the fairings. Whether it's blowing air or not I just thought it was an interesting concept. One worth talking about versus all the gloom & doom that's been filling up Ferrari thread.
As i show on the pic above i think whith that "venturi nozle" they will kill two birds at once:
1. suck air throw starter hole (option) => some precious downforce, but there are also drag (how much, maybe enought "little" or comparable with downforce gain? Maybe is ratio drag/downforce positive to keep on the car)? In my opinion is worth that...
2. also with that created low presure accelerating flow wich go throw crash structure hole and exit under "rain" lights make "cusion"(vortex) or otherwise "kill" big vortices in that DRAGY AREA, without big help of exhaoust gases like did some others teams (Force india, Torro Rosso)...

Very good picture mate. This could work. I'll be interested to see what if anything changes around this area in BCN.
Ah, yes it does seem there is a pipe/tube beneath the hole, didn't spot that.
I still don't see them gaining much velocity in the sidepods after going through the radiators and around the exhaust manifolds. But the air in the pipe might not originate from the sidepod inlets. The pipe might take it's air from the top of the airbox. Then i can very much see a higher velocity of that air exiting then the relative low-pressure area in between the rear wheels.
The gain of doing this is still a bit of a mystery for me tho. Seems like alot of drag for very little downforce.
edit; added cooling for the gearbox seems much more likely, tho even that is a bit of a stretch since surface cooling isn't all that effective without any kinds of heatsinks.

I was thinking the air could come from atop the roll hoop. Although Tombazis said they placed another radiator in the rear of the car. It would depend on it's placement as to whether or not it would be getting sufficient flow and what kind of flow. Neat idea nonetheless. )
to me there seems very little benefit for a aero device of that size to have a dramatic effect on the car.
I think it is a exhaust for cooling air for the rear diff
