The AMuS article is not going very deep in the analysis and is probably also misleading with regard to the likely Bahrain solution.

The other article was going much deeper in analysing the difficulty of setup compromises between qualifying and race pace.

Another point is James Allan's tyre and pit stop analysis of the Chinese race. He predicts a better affinity of the McLaren and Red Bull cars for higher temperatures.

If all this is true the qualifying disadvantage of the old style exhaust could be even bigger than the one seen in China.

I think that under warmer conditions Seb Vettel will not prefer the inside/rearward exhaust to the outside/forward exhaust. It is plausible that Newey doesn't want to split his work and knows which way to go - obviously towards optimizing the outward/forward solution. In this case I believe Vettel and Newey will have the same strategy forward. This should be reinforced by further changes to the rear body work that may be in the pipeline for Bahrain.

The likely Bahrain solution is not going to bring significant performance gains as Marko says, but I hope it will alleviate Vettel's setup problems and allow him to find a compromise that improves his qualifying pace.

Are you serious? What about Marko: "We will go to the model of Mark Webber," Marko told on Monday evening at the station Servus TV."

He said it on tv. There's nothing misleading about it.

"He(Vettel) can't get the confidence he needs with the car," admitted Helmut Marko on Austrian Servus TV, "and this makes him make uncharacteristic mistakes."

Nonetheless, Red Bull has decided that the 'Webber-specification' exhaust is the right way forward.

"We will go on with the Mark Webber car," Marko confirmed.

As for why the team's Australian driver feels more comfortable in the updated car, Marko surmised: "Mark is less sensitive to the (car's) behavior.

"He just needs four wheels, but it's different for Vettel," he said.

I've already posted an in depth analysis on why Vettel is struggling with the RB8 and why Mark struggled with the RB7. It's quite clear and makes perfect sense. But it's obvious RB will continue to develop the solution introduced at the end of Barcelona testing.

I read the AmuS piece as that they will abandon a spec and fo b spec actually

I typed that wrong. You are correct & that's what I meant. Sorry Ray

RB Exhaust comparison; Malaysia to China



I think Mark's Chinese GP solution is a little different than it was in Malaysia.

Are you serious? ...

I am. But you are not getting what I posted. I agree with all sources - Webber, Marko and others that the outward blowing solution will be pursued by Red Bull in Bahrain.

I think the AMuS article is misleading because it portraits Vettel still in support of the inward blowing solution. I don't think this is correct. I'm pretty sure he is already convinced that a further modification of the outward blowing solution will help his setup dilemma.

The second point where the AMuS article is misleading is the speculation of the exhaust they are going to bring. AMuS thinks it will be pretty much what was seen in China. I believe that the exhaust channel in the body work may be the same but that there will be further modifications to the surrounding body work. Naturally this is speculation on my part.

Hmm so he did not copy the Sauber and Mclaren then. the outboard exhaust was concieved in November, but built in February.

The way Adrian Newey tells the story their first version was never something they really wanted to keep after their particular inward blowing concept was declared illegal. It sounds as if they decided to go for an outward blowing solution with a forward exhaust position like McLaren then. It is just that their complete rear body work was conceived for the other solution and that compromised the first three evolutions that they have done so far on the outward blowing style. Buemi and Newey btw confirm my impression that we will see further evolutions at every race until they reach some maturity and optimization of the complete rear body work. It will be interesting to see how big a step will be shown at the next race.

Does the RB blowing concept offer only a very small exhaust assisted diffuser seal sweet spot, and they simply have not found it fully and are only realizing, say, 20% of its full potential?

We have no idea if anyone can actually gain any effect from the exhaust in regard to sealing the diffuser. That the reflective tape used by McLaren in what would be considered the floor target area if you are blowing sides of the diffuser, has anyone ever seen any discoloration from all of the exhaust flow that is going over that spot?

there are better pics but here you go:one example here

This is most propably still THE area for further development and performance gain. If not, the teams wouldn't waste that much ressources for it. Are you supposing all the teams hired idiots as engineers? Your writing seems to imply this...

Discoloration? There are pics from Barcelona testing with completely burnt diffusor top on MP4-27. Please go and search for yourself.
