from memory, that part was homologated but the new drawings not present in the documents they produced in Australia.
Yes, you are correct.This time it is much more serious.
Something is wrong in Citroen. Ford has closed the gap to Citroen (in terms of speed) and wins as many or even more stages than Citroen compared to last year (Ford has won 46 SS and Citroen 32ss). However, their value is still the reliability and their drivers. Now this big mistake with non-homologated part. Causes of managemnt change?

Usually I'm very rational person, but...
What if that was just a Citroens game in favour of mr Loeb. They can't afford their The One (and huge trademark) being beaten by Mikko, immediately after the finn got a compettitive car.

Every teams goal is the manufacturer title... drivers title comes second... and if they want so badly Loeb to get the title they can sabotage mikkos car instead of getting him excluded and be marked as cheater team...
you are not very rational i think...

Ford, for the window issue, got a 5 mins. penalty for all the Focus WRC if I don't remember bad. They weren't excluded.
I think the apeal will not change nothing. It doesn't matter if they gain something or not, the part is a not homologated one, so they're out.

Then Sweden 2012. Proton used lighter suspension arms than homologated. They got 2 minutes penalty and a severe reprimand.

No matter how great the fault of the rule breach is, the rules are final. If the car doesn't comply 100% with them, then its illegal. Plain and simple.
I feel for Mikko, but thats the way it is.
Certainly adds to what has been an epic story for the whole event. The media and promoters would be loving it!

Disappointing end to a disappointing rally. Ok, you have to be at the finish (legally) to score the points but Mads won't want to have taken a win in this way and in fact I didn't like it that the podium finishers were all setting times 1m30 off the pace either. Would have been nicer to see Mads push a bit harder and go for the win on the stages.

2nd April 2012, 14:31
Feel really sorry for Mikko, he drove to an excellent win and now loses it through no fault of his own.
As for Citroen and their appeal, then it seems clear - an incorrect unhomologated clutch part is an illegal part, end of. Regarding the turbo I have two thoughts, that there were no special reasons why Portugal 2012 should affect a turbo more than any other event, and so if it was normal for blades to distort they this would have happened on other events but no other post-event scrutineering has shown any problems, and secondly if there are limits your engineeers should work to a margin that ensures that you always stop the right side of the measurement.
This shows again what a stupid situation we have got into with homologation - there are numerous previous examples of cars being exluded or penalised where there is no performance gain - Brynhildsen Fabia brakes RAC a couple of years ago, Petters slight weight issue last season, Patrick Flodins "old" wheels in the PWRC a couple of years ago, and Fords glass.......it is all too complicated and expensive to guarantee compliance.
Congratulations to Mads

The reason why for non-homologated part every competitor shall be disqualified is to stop discussion about the impact of the use of such part. If there is discussion allowed You get into the never ending spiral of opinions and explanations and into the battle of lawyers. The problem of last years was that FIA often changed the penalty to some lighter ones (like time penalty) for good of big factory teams but in the same time they kept same non-compromise stance against privateers.
I agree that sometimes the tolerances or details specified in homologation are ridiculous (like few grams on a suspension arm of Protons) but since they are existing everyone must understand they are mandatory and they are mandatory for every competitors not only privateers.

in my opinion Citroen must be disqualified.
About the clutch mechanism....
yes it is heavier,but the supplier doesn t product a wrc car spare part by ''accident'' heavier.
Also a heavier clutch cover is more durable.More durable/heavier makes less happy the engine to rev,there is not so good gas response,but is stronger in terms of reliability.
About the turbocharger compressor wheel,we dont know the exact dimension from the wheel they measure.
That the turbo is supplied by Garett to all wrc cars is ridiculus excuse.Ok they are supplied by Garett,but no one will stop you to modify.
The gain is very tiny,as the turbo is with orifice.
The blades cant be longer after some km,while they have measured inside tolerances.
The gap between blades and housing is minimal,if they were geting longer,then they will touch the housing and then kaboom.There are street cars with 2,5 bar boost,that after some 30-50.000 km the blades are not longer.
A wrc team has to be very carefull about the homologated parts.We are talking about a 300 people team,they can measure(and they have to) every bolt or nut in a wrc car.Not a turbocharger,or a clutch cover...
Sorry Miko but thats rallying.Hope to gain another one in Argentina.

WRC.com article - World Rally Championship - News - Citroen heads comment on Hirvonen exclusion (http://www.wrc.com/news/citroen-heads-comment-on-hirvonen-exclusion/?fid=16463)
Seems they are appealing on the basis that they didn't gain an advantage and that the penalties were out of proportion because of that
every team that gets an DQ or penalty says the illegal/mis manufacturerd parts did not gain them any advantage. Illegal parts never ever gained advantage in the autosport. :P

Was the clutch actually illegal? Same way illegal like too light car or oversize intake restrictor? I understood that there was nothing illegal with the clutch, but it did not match with the one in papers. With different paperwork there would not have been any problem?
Of course it was a mistake, and Citroen deserves a sanction. But there are other options too than only disqualification.

Then Sweden 2012. Proton used lighter suspension arms than homologated. They got 2 minutes penalty and a severe reprimand.
I think it is quite OK when new manufacturer enters to the WRC and during the first year, nearly on the first rally, they have minor problems and they get time peanlties and severe reprimand. When next mistake appears then its should end withy the exclusion. Citroen and Ford have been there for ages and their mistakes should not be allowed anymore. Moreover, Citroen has little bit similar mistake already.
So, I am still in the position that every car that is using non-homologated parts or parts which are not like homologation states should be excluded. Only exception can be some minor problems and when the manufacturer first time enters to the sport.

And return to what I said earlier. Agree, to check more than 50 cars is impossible. But at least there are no more than 10 cars, who can be called as pretenders for victory. Why not check all of them before the event? At least 4 cars are the most important?
What is algorithm to choose the car to check after the event?

No :) First imagine You spent hours of testing tuning Your engine and than just before start of the event they disassemble it. I would be furious if someone did it to me and I had to build the engine again just few hours before start! That's nothing less than a sabotage. How would You justify to do so and especially only to someone?
Moreover not many things which were in the car on start are in it at the end and even if You check ten cars You would need an extra day for that.

The clutch was heavier than normal. Which means it could be more durable/reliable, so better... It's the right thing they excluded Hirvonen, fair is fair. FIA can't tolerate any cheating...
Agree. You don't change something unless there's a reason for it. Reliability may be the issue here. This is a BIG mistake from engineering department and highly unusual for Citroën. Knowing the French really well I wouldn't be surprised if heads fall for this.
The turbo issue is what tickles my pickle though.
According to Citroën's chief engineer they knew about this and had already discussed this problem with FIA. My question is:
If Citroën have been competing in WRC since 10 years with turbocharged cars and their turbos have supposedly been checked dozens and dozens of times by scrutineers over the years, why is it that suddenly, at Rallye de Portugal 2012, a scrutineer measures the impeller and finds it to be over sized beyond the tolerance ?? Has it now become so difficult for them to win that they need to push the limits even more? Has there been some restructuring in the team following the new boss's arrival and mistakes start happening?
I am waiting for the lab to confirm if that impeller is over sized or not.
Rallyper
3rd April 2012, 11:47
Having this issue with turbo since many years, may have tempted them to push the limit (e.g. impeller dia) some hundreds of a millimeter, under the umbrella of the known problems... hoping to be innocent when discovered...

I don't know what to think about that. I admit I'm no expert in this area so I just "think loud". In all previous cars they had turbos designed specially for their cars but now the turbo is same for all WRC cars (if I'm not mistaken). I can hardly believe they changed turbine of a controlled turbocharger which was supplied complete by Garret. How and why would they prolong fins by something like 0,1 mm? I think that they would need to produce new turbine to achieve that. But than there is higher risk of failure if the turbine fins get so close to the housing that they can clash with it. So they changed also housing? Maybe yes but than there is a controlled waste-gate (I believe it's how they keep maximum allowed pressure) so they can't achieve higher pressure anyway. Larger turbine have more inertia so it has slower reactions. From my uneducated point of view I can't see a reason to cheat by making turbine 0,1 mm larger. I tend to believe it really can be caused by high-temperature creep and therefore be more a defect of the turbocharger than a cheat.

I can't see a reason to cheat by making turbine 0,1 mm larger.
I don't think there's released anything indicating the actual dimension. The stewards decision only says that it's greater than the testing ring of 54.11mm, and that Pinon stated that it was measured new at 54.02, which is well inside the tolerance by 0.08mm.

Let's wait and see. To me it doesn't make any sense that it could be some kind of cheat. What would larger turbine bring to them? There is limited maximum pressure by controlled waste-gate so there would be no gain in turbo pressure (unless it wasn't somehow modified as well but nothing like that was reported). In my understanding larger turbine reaches it's maximum pressure in higher engine rpm than the smaller one (needs more exhaust pressure for it's own rotation). Due to higher inertia it is also slower in reactions. Maybe I'm wrong but I really can't see any benefit from making the turbine larger no matter if by 0,1 mm or 0,5 or so...

Correct me if am am wrong, but a larger turbo will flow more air and thus make more power than a smaller turbo at the same pressure. Response could be slower but a more agressive tune for anti-lag would compensate for that. But none of this should matter with a restrictor as the cars should all reach choke flow with the same amount of air.
In my mind if this is happening to the ds3, it's also happening to the fiesta and the mini due to the turbo being the same. Wouldn't they have caught on any of the other cars before?

Correct me if am am wrong, but a larger turbo will flow more air and thus make more power than a smaller turbo at the same pressure. Response could be slower but a more agressive tune for anti-lag would compensate for that. But none of this should matter with a restrictor as the cars should all reach choke flow with the same amount of air.
In my mind if this is happening to the ds3, it's also happening to the fiesta and the mini due to the turbo being the same. Wouldn't they have caught on any of the other cars before?
I'm really no expert but I think that as You mentioned due to the restrictor it can't bring more air with same pressure.

Citroën decides not to pursue appeal - Citroën WRC (http://www.citroen-wrc.com/en/2012/news/wrc-news/2700/citroen-decides-not-to-pursue-appeal/)
3 April 2012 | Vodafone Rallye de Portugal (http://www.citroen-wrc.com/en/epreuve/rallye-portugal-2012/)
http://www.citroen-wrc.com/en/epreuve/rallye-portugal-2012/
Following the exclusion of the no.2 Citroën DS3 WRC from the Rally de Portugal, Citroën Racing had initially stated its intention to appeal against the decision of the Stewards. Further analysis of the matter did not uncover any new technical elements. After consulting with various experts, Citroën Racing has therefore decided against pursuing the appeal with the FIA’s International Court of Appeal (ICA).
After having been notified of the decision to exclude the no.2 DS3 WRC from the Rally de Portugal, the Citroën Total World Rally Team had, within the one-hour deadline stipulated by the regulations, stated its intention to appeal against the decision at the FIA’s International Court of Appeal. The team then had a further 48 hours to either confirm its intention to appeal or decide against doing so.
As further analysis of the matter and discussions with experts did not uncover any new technical elements that might have been used to alter the harsh penalty handed out by the Stewards, Citroën decided not to pursue what would have been a long and costly procedure.
Yves Matton, Citroën Racing Team Principal: “We had stated our intention to appeal in order to give us time to analyse the matter in more detail. As regards the clutch, our supplier has sent us a letter of apology acknowledging the existence of a batch of parts which were different from those on the homologation documentation. This letter confirms that it was never our intention to cheat. At the same time, this situation forces us to look again at our procedures, since these parts were not picked up during our own checks. On the second point identified by the scrutineers, the sole supplier of turbocompressors approved by the FIA for all manufacturers, has confirmed to us the plastic expansion of the wheel turbine. Additional analysis will undoubtedly confirm that this was due to wear on the part. We accept this harsh penalty but are determined to learn the lessons and ensure that we will be even better in future. We still lead both World Championships, but the gaps have been reduced. We now go into the upcoming rallies more determined than ever to get back to winning ways.”
Mikko Hirvonen: “Obviously, I am very disappointed but I am not annoyed. These things happen. You have to accept them when they do, learn the necessary lessons and go again. Citroën has done a lot for me in the last few months so I stand united with the team at this difficult time. We win together, and we lose together! This incident just makes me even more determined. I can’t wait to start the next rally and go racing again.”

The clutch was heavier than normal. Which means it could be more durable/reliable, so better... It's the right thing they excluded Hirvonen, fair is fair. FIA can't tolerate any cheating...
but....the clutch they found at Mikkos ds3 was the old design and not the new design which used as a jocker.
Why to use an old part,while they just spent a jocker?This seems that even at top teams they can be mistakes.Of course mistakes=disqualification and thats right.

If Citroën have been competing in WRC since 10 years with turbocharged cars and their turbos have supposedly been checked dozens and dozens of times by scrutineers over the years, why is it that suddenly, at Rallye de Portugal 2012, a scrutineer measures the impeller and finds it to be over sized beyond the tolerance ??
very good question....
Has it now become so difficult for them to win that they need to push the limits even more? Has there been some restructuring in the team following the new boss's arrival and mistakes start happening?
I am waiting for the lab to confirm if that impeller is over sized or not.
Dont think that anybody new boss,will play his career while they are clearly ahead.The lab must be indepented,and not Garetts,if we want to know something true.
Of course thats difficult when ''beside'' is PSA.
About the power,they gained with that 0,1mm i am afraid is not measurable,even not exist.

3rd April 2012, 19:06
But than there is higher risk of failure if the turbine fins get so close to the housing that they can clash with it. So they changed also housing?
In this case you haven t to change the housing but to machine it.
Maybe yes but than there is a controlled waste-gate (I believe it's how they keep maximum allowed pressure) so they can't achieve higher pressure anyway. Larger turbine have more inertia so it has slower reactions. From my uneducated point of view I can't see a reason to cheat by making turbine 0,1 mm larger. I tend to believe it really can be caused by high-temperature creep and therefore be more a defect of the turbocharger than a cheat.
For sure there is no gain from 0,1mm.Just remember that in grN from 32mm to 33mm they gained 20-30bhp.To cheat with 0,1mm(2-3 bhp) in a wrc car that after every rally is going to measure plenty of parts because is 99.9% at first 3 cars is plain stupid.
dimviii
3rd April 2012, 19:09
In all previous cars they had turbos designed specially for their cars but now the turbo is same for all WRC cars (if I'm not mistaken)
previous wrc cars all used garett tr30r turbocharger,except subaru which used ihi rx-6.Tr 30r is a universal racing turbo.

Hi, just to clarify this (as I am a scrutineer at rallies in New Zealand), at the end of an event, scrutineers hold onto a small number of cars in parc ferme and do more detailed checks to confirm the cars conform with the homologation papers. This doesn't mean they ask for the engine to be disassembled necessarily, instead they choose a number of parts on the car and they are disassembled as necessary and checked. This could be anything from suspension, window glass, engine parts to measuring vehicle track and suspension pickup points. This is done typically to cars that win the event or their class, but also some cars are chosen at random so that there is a fair sample across the field. This is done at the end of every FIA sanctioned rally.
Just curious, all cars goes through so deep check procedure?
And return to what I said earlier. Agree, to check more than 50 cars is impossible. But at least there are no more than 10 cars, who can be called as pretenders for victory. Why not check all of them before the event? At least 4 cars are the most important?
What is algorithm to choose the car to check after the event?

Even though you have a wastegate and restrictor doesn't render the rest of the design a coin toss. There's a lot going on below peak pressure ratio and flow, and at any point you want to speed up the turbo as fast as possible. A larger turbine will generate more momentum to the compressor for a given exhaust flow, of course up to an optimal point.
It looked more like it was an aftereffect of Mr Quensel leaving and new teammanager steping in.

A clutch cover does have a function of dissipating heat. And the material / weight will vary this effect. If it would get Petter out of the ditch is probably a stretch though :)

In a Team like Citroen (and also Ford) all parts go through a very strickly inspection and all parts are marked before assembly. I can't just believe that they didn't know that clutch piece is different than it supposed to be.

I don’t understand what is the benefit of having a bigger turbine wheel if the size of the compressor wheel remains the same. The airflow and thus also the gas flow doesn’t increase.

...There's a lot going on below peak pressure ratio and flow, and at any point you want to speed up the turbo as fast as possible. A larger turbine will generate more momentum to the compressor for a given exhaust flow, of course up to an optimal point. I believe this to be correct. The larger turbine will allow greater and faster airflow and will also bring more inertia maintaining higher speed during throttle off ... less lag.
Similarly a heavier flywheel/clutch assembly can have the same effect. Some F2 2WD cars were homologated with heavier flywheels than the standard item for exactly this reason.
Whilst in each case the variance is very small, perhaps the cumulative effect of both illegalities is actually measurable?
In which case ... the C word might not be inappropriate?

The measured difference was under 0,09mm diameter. 0,09mm on diameter is about the thickness of one sheet of paper....
0,09mm on diameter is 0.045 on radius, or around HALF the thickness of a sheet of paper.
Whatever the theoretical difference, in reality that won't mean SFA difference, and personally having watched people who do not handle every single day of their lives micrometers and precision measuring tools, I don't believe that the technical geezers could repeatably measure things that accurately.
All you guys, before you make more of the dreaded pub talk, pick up a piece of good paper and look at it on edge...then imagine half that..

the turbine wheel we are talking was measured not after manufacture but after 3 days of rallying.Citroen says that after extreme stress/temp may they have change the dimension of wheel.We don t know the exact measure.To say out of limits is one word.But if we dont know how much out of dimension it was,we can t know if they were cheating or was a bad measure from Citroen,or the stress/temp cause the wheel to be out of nomimal tolerances,or a Garrett bad manufacture.
Anyway they have punished and that was fair imho.

That might make sense. I know anti-lag is far more heat/stress on a turbo than flat out driving. And mikko just cruised through the rally so possibly so ( no real great way to say this really) his car may have been a situation where anti-lag came into play more than if he had been pushing causing more wear etc on the turbo.

And mikko just cruised through the rally so possibly so ( no real great way to say this really) his car may have been a situation where anti-lag came into play more than if he had been pushing causing more wear etc on the turbo.
No thats not right.Wherever you push or cruise inside a stage, antilag is on.The stress on turbo isn t different if you push or cruise.The turbo pressure is same,so heat/stress same.

Sorry for my ignorance on how wrc cars create anti-lag, but I know at our clubman level it is done by retarding ignition timing greatly when the throttle is lifted this allows unburnt fuel out of the combustion chamber and into the hot exhaust manifold. This creates a big egt spike that spools the turbo, which does cause far more wear than say if I were to never lift.

But you can´t build and count on your driver should act in a special way so turbo will be counted for passing an examination. As a manufacturer you must build for any situation. I think your theories are not countable.

No you can't build, but you can change the engine mapping for it as Anthony warmbold stated in his thread/ on his blog.
