How many races will it take for the other teams to fit diffusers, and other parts to make the aero balance right.

I wouldnt be suprised seeing Ferrari and Mclaren having the diffusers for Bahrain.

Would be surprised if they had not already started them. The appeal was probably an attempt to turn things round but not expected

Some might work immediately, but with no official track testing and cars that were not designed to use such a diffuser it might take a while.

One race before some will fit them. Several races before they can get them to work properly with the rest of the car.

Meanwhile the 3 'diffuser teams' can further develop their cars too, its a long way back for everyone else.

Something to bear in mind is that these diffusers form part of the rear crash structure. The re-testing for crash worthiness may also take time.

yes

Do you really think that the other F1 teams had their designers sat around with their pencils in their hands, looking at the TV, waiting to hear the verdict of the hearing before deciding what direction they would take for their ongoing aero designs? wink

My guess is you will see the likes of Ferrari and Mclaren allready having diffusers ready to fit and fitted for China wether they will work in China is a different matter, working in a wind tunnel and on a track I imagine is a different matter.

I would expect all teams to have a new diffuser for this weekend's race, with the possible exception of Red Bull. How quickly each team can catch up with the Brawn, Toyota and Williams teams is a different matter. I'd imagine that by the European races, McLaren should be much closer to the leading pack.

If I were mclaren and Ferrari I would have had people working on this since the first test.
There is an obvious advantage to be gained and they need to capitalise on it as soon as possible.

I dont think that the rear crash testing will be a major problem. I seem to remember that one team had a car fail a rear crash test (spyker maybe) and they had it redesigned and retested pretty quickly.

I will be supprised if we dont see new defusers being tested on some cars on Friday.
The teams might have been working to ban them, but that wont have stopped them from developing there own just incase the appeal didnt go there way.

McLaren knew their rear wing and diffuser was crap back in feb so I would imagine they are closer to the rest of the teams as they will have been developing something since then.

It worked OK for Brawn! but, alas, I think you are right.

How effective is wind tunnel testing with the @20mph limit anyway? Seems like they will all be using up their drag test allowance which isn't very much either so I guess it will be the teams with the best CFD that come to the fore?

Guy I know works for Renault and he expects that they will have theirs (already developed) on the car within the next couple of races.

Maybe some will be there with them in China this weekend. They have had over a month to develop them, which is a long time in F1. Most will have them by Spain.
Getting them to work properly is a whole different story. Brawn put over a year into theirs. So I guess that some will never get them working this season. It has an effect on every other aero part on the car. To get it right they need to bring out B models.

Red Bull/STR are completely up the creek. But they might be able to develop their existing solution to be better than or equal to the double deckers.

As you say they are trying to hit a moving target as the gang of three improve their offerings based on real track experience.
Are the teams allowed to use the Menorca runway at all this year or is the testing ban absolute? Because Menorca is where most teams would have developed a new aero part on their car over the last few years.

With Brawn I don't think it is just the double decker. It is markedly superior to the Williams and Toyota. So many elements on the Brawn must be better as must be the way they work together. Listening to the team, the car is extremely responsive to set up, this is not something achieved by accident and it is not done by bolting on a trick diffuser. The Brawn seems to have very good mechanical grip as well as aero grip. So there is a lot more going on here than commentators seem to think.

I'm not sure the red bull setup would totally stop them from doing a double diffuser - shame as they have done very well with a conventional design.

I think you can have six or eight aero tests per year - Menorca isn't the only venue (in fact, it has only started being used fairly recently). Kemble, elvington and vairano are also often used for aero testing.

Very true, on current form it would have looked good odds for a Vettel WDC if there had been a ban. Interesting that Red Bull with apparently the most at stake appeared to be the least vocal of the complainants? I think their particular problem in changing design is that they have leveled/cantilevered the rear dampers for a low profile, but this now cuts across the diffuser area whereas the other teams still have vertical dampers?

Some of the teams have already used up some of their 'straight test' allocations. Would be interesting to see how much testing each team has left to them.
