I'd say it's inconclusive. But, if Steve Matchett says it's a "spray bar," perhaps he knows something we don't. I dunno.

This is the give away picture. It shows that the purpose of the tunnel and guide vanes inside it is to help give an even distribution of air-flow through the second set of 4 inch tall guide vanes and finally a even flow over the top of the diffuser. I believe this is to give better pressure characteristics at the diffuser exit and possible better influence towards vortex formation at the sides. Very good Idea. But It must be said that if the ramp was not there, you wouldn't need that foremost set of guide vanes... the second set would have worked OK by itself.

Actually, I think the tunnel is still mostly about keeping the exhaust plume separate from the air flow around the sidepods. The guide vanes at the back aren't so much guide vanes as they are diffuser strakes that extract the air flow through the tunnel, because they initially had problems with it being choked by too much air.

In essence, they have a very legal and literal double diffuser: the normal one below the floor and the new one on top of the floor.

I'm sorry but that does not mesh together. Very very wrong. Especially when you think it is a double diffuser. The very definition of a diffuser goes against your presumption. Double diffuser means two diffusers. The RB8 only has one diffuser as instructed by the rules.

As per the vertical guide vanes, they are nothing new, they have been around. That is why I know that those can function without the tunnel. They work with the small guide vanes inside the tunnel.

I do not disagree that the tunnel is for keeping the "coke bottle" air away from he exhaust. I said so myself paaaages back.

I am taking about the upgrade for silverstone which is the guide vanes inside the tunnel. These internal guide vanes works with the 4 inch tall guide vanes behind them. To even out the flow before it reaches the slotted gurney flap.

I explained myself a bit better in an additional post on this page.

Interesting that the car was quick in hot and slow, and was quick in cold and fast, though admittedly it was not VERY cold in Silverstone, with something like 30 degree track temps. Let's see cold and slow Hockenheim. I think the car is coming on song and could very well spend the rest of the season as the quickest car, though not by much, considering the current season.

Lovely detail of the exhaust and the rear (do I spot a more humpy surface?)

Am I wrong with this comparison? I.E. I'm not totally sure whether VET and WEB used the same exhaust.
Anyway, my humble contribution to their continuing exhaust iterations:

You were right on identifying the "humpy" exhaust for Silverstone. Here is our development blog article about it;

Any sign of off-throttle here?

[JackHammer]

Maybe I just imagined it, but I'm sure I read ages ago about teams being allowed very very limited off throttle blowing in 2012?

you seem to be a bit out of touch!

Why would he be out of touch ? They ran off throttle in winter testing and that got shutdown but i would assume they are still doing some within the rules, since off throttle blowing can mean more then 1 thing just like F-Duct doesnt actually mean anything

they seemed to have an off throttle noise down into the bottom corner of the national pit straight in quali, where as in the race they don't (I was at silverstone)

[ajdavison2]

I was also there and they sounded very raspy braking before club

[Owen.C93]

They were noise through maggot beckets etc which is where you would expect them to be. Definately using off throttle as we already knew. Caterham was the loudest, then a long way back was redbull, then Sauber, McLaren, Ferrari and a bunch of others. Mercedes was the cleanest.

they have been using it for four races now! that is way!

I was at Luffield all three days and there is definately some blowing still going on.. the Caterham was what drew my attention to it first.. it was really loud and then Red Bull.. Webber's seemed to be loudest of the Red Bulls as they went through the hairpin I think it was just the way he approached that corner compared to Vettel which made it more obvious.
