Extra fuel tank?

Paul Harman 3 May 2005 18:49:05
 
Flicking through PA's wire service, as one does, I see that the charges
against BAR involve a 'secret fuel tank' inside the BAR.

I have to wonder what, exactly, the point of this would be. Although there
are shades of "water-cooled brakes" to the matter, I really fail to see what
BAR were trying to achieve. If you need your ballast to be where the fuel
tank is, why not make a heavier tank...?

Where can I find out more about the story? Preferably without having to
subscribe to some web site's spam list...

Autosport Atlas has a great article about the subject - but you'll need
to subscribe to read the site's content. Fortunately, it's well worth the
cost. See http://www.autospor­t-atlas.com/

Not much available free in English on the subject, but there is a
little bit on the Beeb. See:

http://news.bbc.co.­uk/sport1/hi/motorsp­ort/formula_one/4486­869.stm

which pretty much has the same things to say in English on the BAR
situation as GdS does in Italian.

If they were cheating - I'm pre-judging the issue, but that does seem
to be a possibity - then the point would be to run nearly 6 kgs
lighter than the weight limit in the middle stint by using extra fuel
as ballast.

The extra tank - according to BAR - is no secret, has always been
there and Charlie Whiting has always known about it. They say it is a
collector chamber related to maintaining fuel pressure.

All fully documented on the Autosport-Atlas web-site. You really can't
expect to keep up with a sport as complex as F1 through something as
superficial and unreliable as a general news agency.

So the internal tank drains itself at the start of the race (after pre-race
scrutineering) and gets filled up at the last fuel stop?

So the BAR would short-fill at the first stop and long-fill at the second. I
wonder if that's noticeable in their timings. I do recall the FIA's
prediction of how many laps some cars would be doing on their final fuel was
several laps longer than the remaining race duration - but I can't remember
if it was Button's BAR in particular.

Then again, perhaps 6kg of fuel won't get an F1 car very far...

I was kind-of hoping that I could keep up with F1 by participating in this
newsgroup - that is, after all, why I was a proponent and help moderate
it };*)

I just flick through PA because it happens to be right here in front of me.
I don't really expect enormous depth or techincal detail from our coverage,
but occasionally it's the place where I first learn a bit of news and would
like to know more. So I ask questions here - heaven knows, we could do with
a few posts every now and then!

At Imola it is estimated that you need 3.1 kg of fuel per lap - at
racing speed. Therefore it is possible that the car could have been
underweight for the last two laps of each stint - except for the
final stint. At Imola it is estimated that each 10 kg of additional
weight slows a car by 0.36s per lap, so being 6 kg "underweight"
might shave 0.2s off lap times.

So, BAR risk expulsion from the championship for the benefit of half a
second advantage over the whole race distance...? <grin> Although to be
fair, two-tenths in a critical lap could make a difference.

A closer estimation of the advantage is based on the speed running
underweight compared to their speed if they had refilled at the correct
weight. Nearer to 2s per lap for two laps on each occasion. MS needed just
6s to go from 10th to 3rd during the first round of pit stops so this could
be more than a little useful in many race situations.

But, as the Autosport-Atlas article points out, it's not just two-tenths in
a critical lap: compared to a fully-legal car following the same pit
strategy, the dubious car could carry 10kg less fuel over the entire race
distance. That might have added up to some fifteen seconds over the course
of the Imola race.

But the reality wouldn't be like that (I think...)

Assume BAR and fully-legal car are adopting the same strategy (1 stop,
for argument's sake). They'd start the race at the same weight, but with
the extra 6kg of fuel they'd be able to stop two laps later. From then
on, we can assume both cars would weigh the same to the end of the race
(when they'd be weighed in scrutineering, and would weigh the same). So
the advantage is running 2 laps with hardly any fuel vs. the "legal" car
running those 2 laps fully-fuelled. I think the pitstops would take the
same time, as although the BAR would now need to consume 6kg less fuel
than the legal car to get to the end of the race, they've also got to
fill up the "missing" 6kg to get back to minimum weight.

I hope this kind of makes sense. It's still quite a significant
advantage, running a couple of laps something like 50kg down on your
opponent. But that's the kind of thing that can happen in race strategy
anyway, e.g. with someone coming in early due to backmarkers, or staying
out an extra couple of laps, etc.

I wouldn't ever bank on usenet to keep myself informed. Much of what
is posted is, after all, pretty ill-informed <g>. Anyway, most of it
is opinion, which is as it should be.
I just flick through PA because it happens to be right here in front of me. >I don't really expect enormous depth or techincal detail from our coverage, >but occasionally it's the place where I first learn a bit of news and would >like to know more.

No argument with that, but as I've said before, there isn't the same
need for this newsgroup that there was a few years ago.

If you're serious about keeping up with F1 you really need to check
out the newsgroups on a daily basis, though. If you're not prepared to
subscribe to Autosport-Atlas there are alternatives. The ITV site used
to be OK, although I haven't visited it this season.

Anyhow, BAR's defence seems to be based on the fact that they don't
run the cars underweight because the extra fuel needed for the
collector is on board all the time. What they are effectively doing,
therefore, is including this fuel as ballast. They claim they think
this is legal. It clearly isn't.

Plus, of course, they are saying that we are good guys and wouldn't do
anything illegal deliberately. If we have misinterpreted the rules,
please accept that we did so in good faith and just give us a little
fine. (Oh yes, and if you do chuck us out we'll probalby take it to
the civil courts because we will have nothing to lose.)

Bernie seems to think they will be found guilty. He is suggesting they
shouldn't be thrown out, but that a fine would be insufficient. His
proposal is that the team loses its points for the whole season and
the drivers lose their points to date.

Of course, if they are thrown out he is down to 18 cars. He can't
insist on other teams running more cars because the field had 20
entries at the start of the season. On the other hand, Mclaren are
running a third car on Fridays anyway, as are Sauber and Minardi, so
there might be 'volunteers'.

Luckily, there is no need to be "serious" about keeping up with F1, in
order to be a member of this newsgroup, and just taking an interest is
allowed. Therefore, one does not need to "be prepared to subscribe" to
anything. Gosh David, you take F1 almost as seriously as it takes
itself! Let's not start being to superior about whether or not we're
"real fans", shall we? Room for all here, surely!?

If the fuel is *needed* for the fuel system to operate, then it is by
definition not ballast, as is every other part of the car that is
required to be there in order for it to work properly. That the FIA have
ruled that it is ballast implies, to me at least, that if it was
removed, or if enough of it was removed to bring the car below the 600kg
limit, then the car would in fact continue to work as if nothing had
happened. In that case, it would be ballast.

No intention of being 'superior', Kim. Not sure where you get that
from. Simply saying that if you want to keep up, this isn't
necessarily the best place to do so. You have to read what I said in
the context of the post to which I was replying.

Will's point was my viewpoint.>From what I read the rules stipulated minimum weight
during event, they did not specify 'dry weight' after the event.
But obviously, the powers and the process have decided
differently. So it goes.

Clear?
I do not think the rules were clear.
I agree the 'final' ruling is clear.
But I also remember the Tyrell 'travesty' of justice.

I am sorry about brevity and unclearness of above
(gotta finish up loading and pull out to tow to weekend race).
There was certainly concern that the punishment
against Tyrell was unduly harsh, and had more to
do with his vote (which is supposed to be 'free will')
than it had to do with the concerns about the team's
alledged 'technical violations'.
Very chilling. When the powers and majority are
against you, be careful of how rules may be interpreted!

"Well of course you can vote the way you want!
It's just that after you vote, we may chose to
draw and quarter you, then decide the vote is
fradulent because it was cast by a dead man!"

Everybody else seems to have understood that you can't run fuel as
ballast <g>. If the rules weren't absolutely clear, BAR should have
sought clarification before building the car that way. I think that
was part of the ruling, wasn't it?

More is coming out all the time. It seems that the FIA has pretty much
known BAR was up to something since the beginning of the season. Also,
iit seems BAR's own legal advisers are telling them they are lucky to
have got off so lightly.

no, reading their pdf downloaded from their website, they
include the rules, which states the car must not weigh less
than x kg during the event, and the event is defined as
qualifying or racing. They also say to weigh the car
they may require a flying lap , stop the car and weigh
Removing the fuel would mean the car could not be used
in the event, nor could it do the flying lap.

regardless of opinion, Bars document makes good reading....

But, there's one thing I don't get. As you say, FIA has known BAR was up
tom something. Why on earth haven't they made any move to clear or
confirm? Did they have to wait for BAR to score some points so it would
look more spectacular?

I don't get it.
