Red Bull RB8 Renault

you can see the setupwheels in the picture restingh on the corner platforms.

Also you can see the bottom box for the KERS Battery in that picture lurking out of the heat shield molding

Given the inability of 2 different aero teams to get the tunnel working - one headed by Newey/Prodromou and the other by Iley, does anyone think they might just be exploring the bulged fairing route now? A la Sauber, McLaren etc.

They should be, but I wonder if they'll compromise their approach because it may not suit Vettel. There are most probably other larger factors at play, but the McLaren style exhausts don't seem to be suiting Button at all. He's constantly complaining about rear end stability and trying to sort that is compromising the rest of his setup by inducing too much understeer. You do have to wonder if this is at least somewhat to do with the exhausts. Vettel doesn't cope with a similarly imbalanced or inconsistent rear, whereas drivers like Hamilton and Webber can thrive in those conditions.

[raymondu999]

Actually I'd put the analogy the other way around, personally - Webber likes a steady rear. I remember in 2010 around Monaco time Webber was asked what has helped him to beat Vettel in the last two races (then it was Spain and Monaco 2010)

He said, "It's the tyres mate. The narrower fronts give the rears more lateral stability, which I prefer. Seb likes it the other way around."

To me really the bulged fairing vs exhaust coanda ramp (a la Red Bull/old Sauber) are just a means to an end. Newey is trying to make use of two flows with his tunnel - the coke bottle flow and the exhaust flow. The bulged fairing provides less control over the exhaust but allows more coke bottle flow, and the tunnel, in theory, vice versa. Nothing more, nothing less.

I don't for one second believe that Button's issues with understeer are exhaust related. Button performed fantastically in China and Melbourne on the same exhausts, and was competitive with Lewis (ahead, even - albeit only by 1 spot) when he plowed into Karthikeyan in Malaysia. I'm quite certain it's another issue that's hampering Button.

What is the basis for this statement? How do we know one allows more control than the other?

ps - Lets not contaminate this thread with talk of driver's styles.

[raymondu999]

I'm basing it on that the coanda ramp has the ramp to guide the path all the way through, while on the flipside, the bulge fairing has the exhaust jump through free stream air. I think the "constant" guidance the ramp provides means the exhaust path will be a lot more consistent between low and high speed situations

[Richard]

Thanks. I guess we could explore that further in the coanda discussion. viewtopic.php?f=6&t=12046&start=645

To get back on topic it'll be interesting to see if RB persist with the tunnel.

Nice profile of what appears to be the exhaust fairing/shielding in the left background.

I still don't quite get the brake cooling on the RB8. I always understood it as air goes into the hub and out through the holes in the disk (while some gets split off for the caliper). While RBR have a duct that just blows some air over the edge of the disk. I haven't seen any other team do this but maybe you guys can remember something like it.



(Also they're using the duct for Monaco: http://www.formula1.com/wi/sutton/2012/d12mon274.jpg)

How can you come to such a conclusion when he literally dominated Australia, he was a tenth away from Hamilton in Qual.
He then was only 2 tenths away from Hamilton in Malaysia.

Setting aside his results, which have in any case been poor in the last couple of races, have you listened to what he's been saying over the radio to the team? He's been whinging a LOT over the radio to the team about the balance of the car.

[Robbobnob]

That brake duct blows across the edge of the disk to force the air being ejected out of the holes, due to the rotation, outwards. It helps to lower the pressure at the disk edge to allow a higher flow through the disk itself

Yea i heard him complain over the radio a lot. However this was in Spain. Not all other tracks.

How does the average individual, me for example, get access to radio transmissions from the race like you guys?
