EBD ban - turning point in the season?

SOme journalist claim it will destroy Red Bull's superb qualifying pace.
Sometimes I think it will bring a McLaren-era and sometimes I think it won't have any effect, because Newey will come up with a new idea which he will suprise everyone again.

I think Ferrari and McL will be extremely fortunate if EBDs are banned in the middle of the season. It's basically outrageous that such a major change in the rules could be implemented in the middle of a season (certainly at least when they so obviously could have been implemented before the start of the season rather than in the middle of one). However, I think the very reason it is outrageous is the reason it might be implemented -- implementing it will artificially reverse Red Bull's advantage and reinstate the status-quo (i.e. the teams that are "supposed" to win will be artificially boosted). If the FIA banned it at the end of the season then they would not achieve their objective (of handicapping Red Bull) because Newey would do his usual being better than everyone else at adapting to rule changes. The reason it is different in the middle of the season is that there is only a much more finite amount of adaptation possible where the teams are restricted to working with the chassis the already have.
The reason is that it's not a change of the rules.
It's a change in interpretation of the rules by the F1 Technical Department.

Why not? It worked in 03.I would be very disappointed if "off throttle downforce" is banned even if it might benefit Ferrari or make the championship closer. Red Bull have built a monster car so let them be. Mid season rule changes or changes in interpretation is not the way a championship should be won or lost.

I think there is a common misconception that the off-throttle blown diffuser is going to hinder Red Bull more than other teams, and from everything I've seen, I don't see it happening.
I saw an article about Red Bull relying 40% on off-throttle gases to help their diffuser generate downforce, McLaren and Ferrari are somewhere around 70% and Renault are around 95%.
If that's true, Red Bull will be aided by the ban.
Also, CH doesn't seem to bothered about it, he seems to just say "if they ban it, we'll accept that and move on", he's not protesting like Renault and other teams seem to be.

Just thinking, Williams looked good at Monaco... and they're one of the few teams without the EBD. By far and away the most competitive of those as well...
This is something I hadn't thought of and actually makes me more sympathetic to the "change in interpretation". I'm sympathetic to Williams and Cosworth if they are only not able to do EBD because of their more limited resources. I don't like the idea of a team being handicapped by the fact that they don't have the engine of a wealthy engine manufacturer who has the resources to do things that Cosworth does not. This, in effect, is like the engines not being frozen.
But I still thinks it'd be very regretable for all the other teams (most obviously Renault) to have invested in EBD tech only to suddenly have it yanked out from under them 6 races into the season. It was so obvious that this tech has been being used by the teams going back all the way to around Hungary last year (e.g. the dramatic new sound the McLs were making suddenly). It should have been sorted BEFORE the season, not after everyone has designed their cars.

There might be some changes in the balance of power between those teams, but i believe RBR will still be ahead.
I think Renault will suffer (the car is pretty much based on the diffuser concept), Mercedes and Williams might profit from it.
All this is just hunches however, no evidence whatsoever, i might be horribly wrong.

Their biggest advantage has been in the faster corners and this was most visible in Turkey T8 and Barcelona T3 and T9. These corners are, of course, very much on-throttle. With that said balancing a car with massive on-throttle downforce with a newly imposed restriction on the overrun would not be easy but that goes for everyone.
I wholeheartedly disagree with 'changing' rules (or their interpretation) mid-season and hope the TWG say that it is not feasible to do so.

I don't think it would take much to get the McLaren ahead of the Redbulls. In my opinion the McLaren is now the faster race car, with Redbull having the single lap quali advantage. So take 2-3 tenths of Redbull and it's possible that McLaren may be the new team to beat.

I also think it's a bit ridiculous banning EBDs mid year.
Yes but you can't discount strategy in the year of the banana peel tyres. RBR remains the team to beat not only because of its qually advantage (and that advantage is further augmented by the drivers RBR happens to have) that sets it in front at race start, but also due to their in race RB7 package combined with their strategy (again, augmented by drivers that make it work).
RB did not win either of the last two Sundays because it was the fastest car. It got into the lead on strategy and held it on sheer sweat and guts (even if you only count Monaco to lap 70)

Williams has an EBD just that its **** and they can't get it to work like the top teams or even Team Lotus standards. Mercedes run and EBF and Renault an FEE.

Last time I checked they were about to limit off-throttle usage of exhaust gases, not ban EBDs .... and these are two completely different things, yet everyone here seems to be convinced that EBD will be banned altogether. Secondly, we can't say who benefits the most (and therefore will suffer most) from off-throttle gases simply by looking at some numbers (pulled out of thin air) from some article. It's not that simple. Finally, some people seem to think that Williams will benefit the most from banning EBDs, because they don't have one ..... wtf??!! Of course they have, just like pretty much everyone except Hispania (even Virgin tested their not so long ago, I don't know if they're racing it or not). Tip of the day: Read, then post, not the other way round.

Anything that cracks down on aero is a good thing.
But the EBD gives the cars downforce which doesn't fall off in turbulence. Getting rid of it is surely a bad thing in this instance ?

TURU ........... agree 100% .... people getting the issue wrong..... like you said its about the engine mapping in off throttle corners where fuel are being burned in the exhaust resulting in exhaust gas flow over the EBD creating extra down-force in corners when off throttle.. you can hear the difference in engine sound when the cars are in a off throttle situation... its makes a deep growling sound

I also can't remember if the RB6 had the off throttle mapping until later on, I think it had it from the start. But if it didn't, it was dominant without it and with it in qualifying.
It didn't. They had to play with the throttle. Webber was very good at it and this helped him beat Vettel a few times in the first half of the season. They introduced these mapps in Valencia or Silverstone (or somewhere around these) and since then Vettel had the edge.

Then look for a source not further than Autosport. There must be in the archives an interview with Pierre Dupaquier by Bira. By his own words they changed absolutely nothing on the tires, just added white strips on both sides of the protector area.

I am very worried this will hinder McLaren and Ferrari more than Red Bull Lets just leave it as it is and let McLaren do the catching
I think the most realistic way the ban could possibly help Red Bull (but I do not think this is necessarily the case, it is just an idea) is that they will have better race pace relatively to the rival teams, at the expense of sacrificing some - but not all - of the qualifying advantage. That is, maybe the reason of the large discrepancy between Q3 and race performance is not necessarily just that RB are using more overrun in Q3, but perhaps also less in the race. This could be the result of e.g. the McLaren having better cooling, so that they can run it more over a race distance, while Red Bull have overheating problems (KERS usually does not last the whole race), and they have to turn it down a lot.

Clarification, as the thread title is misleading.

If I remember correctly they suggested it being limited to 10%
The problem here is that the mapping uses more fuel up to 10% more according to Renault and creates excessive heat in the exhaust system.
RBR is using it in Q3 by turning it up hence their jump in performance from Q2 to Q3 but in the race they don't use it or only limited (extra fuel usage and heat issue) resulting in the Ferraris and Maccas being "closer" to the RBR during the race.

That was the FIAs initial position, yes.
Where it will go from here is anyones guess though. Newey has already stated that ,for RBR, the throttle and exhaust valves being opened on the overrun is a reliability feature incorporated by Renault.
There will be a lot of differing interests at the TWG and a common position, won't be easy to find.

I have a lot of respect for Newey but in all honesty I believe he is just playing the "reliability" card to put pressure on the FIA not to ban the engine mapping.... the way I understand it is that they basically changes the timing electronically resulting in the ignition taking place a little bit later when the gasses have exited the chamber ... so I cant see that it will cause reliability issues... as it is the RBR does not use the engine mapping "******** ignition" system in the race or to the same extend they do in Q3... so it should not be a problem for them to stop using it BUT it will impact on their performance come Q3

RBR race performance
Fundamentally, Red Bull Racing’s qualifying advantage lies in the optimisation of the use of “******** ignition”
RB7 is able to maintain 95-100% of its exhaust gas output when the drivers are off-throttle. This towers above much of the opposition, who at the best of times are believed to be able to exert 70-80% of normal exhaust gas output when off-throttle.
Red Bull’s qualifying runs rely largely on the “blown diffuser” and off-throttle exhaust-gas release.

I think all of the teams are retarding the ignition in the race just much less aggressively than in qualifying.
Newey wanted to give the impression that the open throttle was only acting as an 'air pump' whereas by injecting fuel and combustion happening in the exhaust manifold it is essentially acting as an 'afterburner'.
If the FIAs proposal was to be implemented, all the leading teams would have issues (the same sort of issues that lead to EBD development being abandoned for more than a decade) and the cars would be much more unstable at corner entry (and under braking) but even if they have to pull back on the degree of EBD aggression when on-throttle (to reduce the change in balance which causes that instability), Red Bull would appear to still have the car with more downforce than anyone else.

So, is this hot blown or cold blown systems? i seem to think its both.
Indeed.
The FIA's directive would have treated both the same however as it only dealt with the extent to which the throttle is open, not whether fuel is being burned outside the cylinders.
