Theissen says it does create dirty air for the following car. I'll take his expertise over yours.

Well, if they keep limiting everything, and making "standard" components, we'll be left for F1 cars being no more cutting edge than A1GP of GP2 cars.

I say open up the regs, but I've already made that rant earlier in the thread I think lol

Oh, and from wiki


"A diffuser, in an automotive context, is a shaped section of the car underbody which improves the car's aerodynamic properties by enhancing the transition between the high-velocity airflow underneath the car and the much slower freestream airflow of the ambient atmosphere. It works by providing a space for the underbody airflow to decelerate and expand so that the boundary between the car's airflow and "external" airflow is less turbulent. It also provides a degree of "wake infill" (the wake being a turbulent area of low pressure that is caused by the passage of the vehicle through the air; this can cause pressure drag).

As the air enters towards the front of the car it accelerates and reduces pressure. There is a second suction peak at the transition of the flat bottom and diffuser. The diffuser then eases this high velocity air back to normal velocity and also helps fill in the area behind the car making the whole underbody a more efficient downforce producing device by reducing drag on the car and increasing downforce.

The aft part of a car underbody can be a diffuser. It works to bring the low pressure air below the car back to the ambient atmospheric pressure without inducing turbulence. It uses Bernoulli's principle, such that the pressure increases while the velocity decreases. Since the pressure below the car is lower than on the side and above the car, downforce is produced if implemented correctly. Injecting the exhaust into the rear diffuser can also help extract the air from below the car. The exhaust gasses effectively energize the boundary layer, helping to raise the pressure of the low-pressure, fast-moving airstream back to the ambient atmospheric pressure at the exit of the diffuser. This helps extract the air more efficiently from the underbody."


No disrespect to Dr. Thiessen, but I wasn't wrong in what I said. He's pissed that his cars weren't designed with this interpretatoin of the rule in mind.

You wiki excerpt doesn't mention dirty air behing the car, so still I believe dr. T.
I don't believe he is pissed, he's mr Flanders of F1, he doesn't get pissed. For pissed look for Flavio:

quote:

"After the death of (Ayrton) Senna the principle was to not give certain (ground) effects to the cars, but now suddenly it's all legal," the Italian told La Gazzetta dello Sport. He said the current pecking order, with Renault, McLaren and Ferrari struggling, and the Brawn Mercedes drivers out in front, is an affront to F1's credibility. "Our drivers are or have been world champions, and then you have a (Brawn) driver who was almost retired, and another who is a 'paracarro', fighting for the championship," said Briatore. "I don't know how we can say we have credibility." A 'paracarro' is a concrete roadside post, and it is not clear if Briatore was referring to Button or Barrichello. With a modified diffuser, Lewis Hamilton was quickest on Friday morning in China, but Briatore doubts the original 'diffuser three' can be so easily caught. "It is impossible to recover the ground we have lost on those teams," he insisted. "In three or four races the championship will be decided and I don't know what the interest of the TV viewers will be when Button has 60 points and Nakajima 50. " "It will be better to listen only on radio and watch something else," said Briatore. He also said the current situation has made a mockery of Max Mosley's proposal to impose a 33m euro budget cap next year. "We have spent 15 on KERS, another 10 on the diffuser, so we have five left for travel and to pay the employees," said Briatore.

Flavio is livid, but his cars will also have the double diffuser this weekend which suggests that they were designing one in parallel while waiting to see how the challenges played out. McLaren also has an adapted double diffuser in use this weekend.

Ferrari took their KERS off and the cars are slower. Not looking like a good year for the prancing horse.

Nope, that $40mil/season for Kimi is going right down the drain.

LOL I wish Flavio would just shut his hole and focus on racing. The guy is such a bitter and arrgoant twat.

Briatore wants money blocked from Brawn

By Jonathan Noble and Michele Lostia Saturday, April 18th 2009, 03:25 GMT

Furious Renault boss Flavio Briatore plans to propose to fellow Formula 1 teams that Brawn GP is blocked from being given any television rights money for the 2009 season.

As the successor of the Honda Racing team, Brawn GP has a theoretical claim to the estimated 30 million Euros of money that would have been due to the Japanese manufacturer for competing this season - a move that was supported by the Formula One Teams' Association (FOTA).

However, on the back of the diffuser controversy and the extra costs teams are now facing in developing the concept, Briatore instead wants the money to be shared equally among Brawn GP's rivals.

Speaking to Italian media in the Shanghai paddock, Briatore said he would make an official proposal to FOTA to prevent Brawn GP getting hold of the payments.

"Despite some being against it, [Luca di] Montezemolo kept the FOTA united in supporting Brawn GP, and so did McLaren, in supplying engines," said Briatore.

"But since [Ross] Brawn was our technical delegate, and he forces me to spend money I don't have in my budget, and since Honda's money have luckily not been shared yet, we'll have a meeting.

"My proposal will be as follows. Brawn is richer than anyone else, because he's had his team paid for in full by Honda, plus he's had 130 millions given to him [by Honda]: he's certainly richer than I am.

"I don't want to be a Robin Hood, but when there's a situation where everyone is transparent then it's fine.

"At this moment my position is, since I need to find the money in the budget somewhere and the season can't end up with [everyone] being one second behind the Brawn cars, then the money share will have to be reviewed in full. I think it's around 30 million Euros."

Brawn GP has no guarantee of getting the Honda money because it was made a totally new team by the FIA. Had it been a simple renaming of the outfit, then rival teams would have had no call for the payments.

Briatore added that he would also push for Brawn GP to not receive any entitlement to transport costs - which are only guaranteed for established teams.

"Let's go with what the FIA said," he explained. "Since the FIA said it's a new team, then for once we agree with the federation. This is a new team, it's true: Honda officially said it left F1, and this isn't called Brawn Honda, it's Brawn alone. At this point I think the federation is right.

"Bernie refused that point because Bernie wants to send the money to the teams and the teams would transfer it. Brawn was very good in the appeal, so the federation said he's right.

"As FOTA commercial chairman I'll propose that we follow the FIA's indications that it's a new team and for three years it has no rights with regards to transportation, nothing."

When asked about the previous stance of FOTA members ensuring Brawn GP got all the money it was entitled to, Briatore said: "That was at Christmas, though. Now that Christmas has gone, we'll talk about it again next Christmas.

"Since it's a new team, it has to follow all the regulations we followed when we entered with new teams. I will propose that to FOTA, then we'll see."

It's an interesting grid for tomorrow's race! The new double diffuser fitted to Alonso's car seemed to help. I wonder if the two Red Bull cars are just way lighter? It will be interesting to see the weights once they are posted.
