24 Heures du Mans 2011 - 79th Grand Prix d'Endurance - June 11-12

I'll ask something technical here because this has had me stumped for the past 22 hours. The Peugeot's and Audi's are running a shark fin, but the Audi's seems connected to the fin all the way from the roof scoop. Are they using all the internal area from the fin to aid in a ram-air effect??

Count me in as one of those thats watched this race from start to finish non stop, gotta love Le Mans!

That fin is to stop them from flipping when they go sideways.

Audi may shade this... Peugeot looking a little erratic. Especially Gene

Allan Mcnish! He's on Speed.

Oh my! Robertsons could spend their anniversary on the #LM24 podium?? What a story!

Says tweeter. I say, YES PLEASE!!! Epic marriage is epic.

I'm sorry, I'm just too romantic . I, for example, cheer on Peter Sauber because he names his cars CXX because of her wife Christine .

I'm using my good headphones right now so I won't wake up the girlfriend. Don't want to wake her up now as I had a free day just for the Le Mans. Listening to cars makes me wants to sleep anyway, it's like hearing god speak to me.

You wouldn't want to know what sounds like these would make me want to do

 

[mafia_boy]

Oh I know what the fin is being used for. The difference though is that the Audi's is connected to the roof scoop where the Peugeot's is a standalone unit. Hence why I'm asking about the internal area of the fin being used in conjunction with the roof scoop to allow more air in to create a ram-air effect.

 

[Furinkazen]

Brilliant for Robertson... think only 4 are going in GT AM

 

[cicua]

Pug went off at the chicane!
Probably no penalty for that...

Why would there be a penalty for that? Audi #2 was not penalized for going between the same green poles.

 

[Luminis]

Dang, the rain's getting stronger, it seems, track's getting slippery again!
Audi preparing intermediates now!

 

[C-ZETA]

I mean, it's easy to get irritated if you're on little sleep and maybe a Peugot fan (),

Come on, don't be such a fanboy...just because it's Audi vs Peugeot doesn't mean you have to hate on the other side. ...........

Uh which part causes the ram air effect? I think Audi has just maximized the size of the fin to create a greater stall effect when the car is travelling laterally. Seems to work too as evidenced by the 2 written off R18's that stayed relatively close to the ground without flipping over (McNish's roll over excluded as he caught the end of the ARMCO).

Nah, I just think it's natural to get a more agitated if your favourite team is in second place, that's all

They might not be fast, but hey, they've fared better than big budget teams (Ehem...Aston Martin...), they've excibited good sportsmanship (Ehem...You know who...), and they are going to drive the car to the finish line in one piece. Great job.

#9 in pits for fuel.

But they are still two laps down from 3rd place. Great race though.

The Audi manager had to go to race control twice for something simmilar.

 

[Prince.M5]

So almost all the Ferraris are having a gearbox issue with the #83 being the latest victim...

I would assume it does these things,

Improves rear-end efficiency and balance.
Straight line stability improved
and better management of airflow
reduces some turbulence from the air inlet.

This was for F1 but i assume it´s the same deal here. To some extent

 

[m00ndancer]

Sigmatech and Level 5 is on the same lap

I was not aware of that.

Look at the Audi, and see how the fin is connected to the roof scoop?? Now, to me it seems, it looks like the air goes in the scoop and into the internal area of the fin as it looks like from the design of the car. I agree with you and scalage as the fin does reduce the lateral effect on the car but it's so different between the Peugeot and Audi design that it looks like the Audi's one has extra purpose to it.

Maybe I'm just seeing things that aren't there.

 

[Luminis]

Is Lotterer on intermediates now? Commentators aren't being clear about it.

 

[Furinkazen]

I'm looking at the weather radar... looks very wet...

It doesn´t. Watch the pics of Mcnish car. It goes straight down to the engine.

It´s to clean up, stabilise and improve airflow.

Maybe we are just not qualified enough to answer your question

 

[CarBastard]

Oreca Matmut 908 going in the garages.

Several reports of rain, I hope Leena does the right decision again at the Audi pit.

 

[Scalage]

Still a full GT1 race length to go. I really feel like it'll never end.

No, there's definitely people that can answer my question!

Famine, please help in answering this for me with that big delicious genius brain of yours!!
