[WEC Race] 2012 Six Hours of Fuji

40 sec over 6 hours means 0.166 sec per lap.

On Wednesday Lotterer did a double stint. So you can see exactly how long a fuel stop including pit in and pit out takes.

In http://www.dailysportscar.com/viewAr...D2E10C85AFF5A2 Vasselon explained that the tipping point is around 0.2 sec per lap.

And that is the key, while there are those that look at the need to take a splash at the end of the race and see it as a disaster, we look at the time it takes to get a little fuel and convert that time into what would be require earlier in the race as a reduction in pace to make it unnecessary to take that stop.

The difference across the six hours is 0.2 seconds per lap – Anything we do to reduce pace to secure the need not to take a splash cannot cost us more than 0.2 seconds per lap as it would, over the full distance be a less efficient use of the time available!

They're already so drag-limited that I can't see them gaining much of anything trying longer gears at Le Mans, especially if they run more downforce.

It's still hypothetical.

Also, how is it possible to run only 311km/h in qualifying at Suzuka, with free reign on DRS, and run 318km/h in the race with no DRS, and 322/323km/h with the limited allotment of DRS? Sorry, those numbers do NOT add up.

Do you mean the tv graphics telemetry or what because f1.com do not have speed traps from races? I just really can't trust you remember those figures right.

Also, the number from Spa qualifying is 310km/h, but weren't we seeing 311-313km/h from the Audis last year at Spa?

gwyllion corrected this.

I must say that I really don't feel like I can count DRS-generated speeds as legitimate. If they had free reign to use the system in the race (which I know would defeat the point of it as it is intended), that might be another matter. However, it is what it is, and not a Chaparral flap, so it really comes off as a video game feature. I really cannot see it as an accurate reflection of what the car setup alone would make possible under the current conditions.

It's still happens to be a feature of the current cars, but you can also compare to 2009-2010 no-DRS cars, which really doesn't change much because the top speeds are still higher.

Deggis, I don't know what to do with your second link. The listing on the left almost instantly goes from clickable links to straight text, so I can't actually click on them to get any session results. (I checked my Adobe Reader, and no notice of needing an update came up, as far as I could tell.)

Practice sessions are being streamed with RLM commentary, circuit looks quite busy.

Sound is out of sync by about 10 seconds, lol.

Yeah, it's quite amusing

Kaz put in a really impressive time at the end, a 27.5, awesome!

[TF110]

1:27.567 for Nakajima, blasted that lap., up 7 tenths on the Audi.

Not surprising. Home track for the whole team gives them a morale boost, I'd expect.

[Purist]

Nakajima threw down a 1:27.567, with Treluyer on a 1:28.296.

Interesting interview there with Nishy on RLM.

Nakajima is just good at Fuji, period. He's raced there countless times with SuperGT and F-Nippon.

Am I the only thinking Toyota is a legitimate contender for the overall at Le Mans next year?

Lmao, they're gonna win it by like 15 laps next year.

I've been saying this since the 24hr.

It's not amusing that this is 7/8 round and most of them have had some sort of technical issues. Async audio is a new one, but distorted aspect ratio, just unbearable audio quality etc.

I think its on the RLM end. When they did a montage at the end, it was perfectly synced.

[Purist]

Deggis, I checked the TV telemetry during the Japan F1 race; I don't have an inherent reason not to trust it at present.

As for the Spa speeds, either the tables are lying, or the commentators from last year's race coverage were lying; take your pick.

Based on the speeds that the cars are simply stalling out at without DRS, the current F1 cars are carrying more drag than even the V8-powered ones of just a few years ago.

On the TV graphics, the quickest I saw at Monza without DRS was 325/326km/h from a Mercedes. A 2008 Peugeot did 327km/h, and though power for LMP1s has dropped since then, the commentators on the Le Mans coverage in the last year or two quoted speeds as having gotten back to 2008 levels in terms of the top-end, caused by more trimmed-out setups on the cars at Le Mans now. (I would also imagine that the narrower rear wing decreases the inherent drag of the current LMPs.)

Thanks, I'll look for that plus sign on the WEC page.

With telemetry you mean the onboard telemetry? It isn't shown all the time though.

I have no reason not to trust numbers I can go recheck (and you can too) right now, so I think I'm going to trust the tables. I'm not saying they're lying (you mean RLM?) but just really doubtful if you heard it correctly and even if you did you still remember it correctly. And where would they have gotten these speeds if not from the official timing?

The official speed trap spots might not be always in the optimal places but at least I'd expect them to be in the same places every year.

No DRS in 2009/2010:

Somewhat true, at least for Peugeot (pdf) last year.

This might sound like a crazy idea and please dont call for the white van but surely in this day in age you can have the radio commentary and the tv pictures linked so that they are not talking over the pit interviews?

Just putting it out there....

ACO is why we can't have.

Good lap by Nakajima, even Akio Toyoda welcomed him!

[deggis]

Full qual session already (!) online: http://www.dailymotion.com/video/xua...-live-rec_auto

(For the first 10 mins or so audio and aspect ratio are totally screwed up, of course.)

[Purist]

I can re-watch race recordings, and re-check that way, so the tables are NOT unique in that respect. And you just said so yourself, that the traps may not be in the optimum location, so I prefer to have the onboard resource, if available, to look at.

As for trap location changes, well, it is an ASSUMPTION that they don't move. In fact, it is a real count against them if they never move in response to changes in the performance characteristics of the cars. Also, at Le Mans, for instance, some years, the trap has been on one section of the Mulsanne, while in other years, it has been on the run to Indianapolis.

On that topic, the Suzuka speeds listed for F1 make me think that that speed trap may be right before the Casio Triangle, and NOT either right before 130R or before Turn 1.

Also, you conveniently cut off one of my paragraphs, where I tie in that top-end speeds have been reported to have returned more to 2008 Le Mans levels. Of course, I know DRS wasn't around before 2011, but then again, F1 isn't using those cars now, nor was I trying to draw a parallel between F1 cars then and now.

[Purist]

it was nice to be able to watch the sessions. That was a darn good lap from Kaz. I wonder, with the seeming lack in falling lap times through the successive sessions, whether the fastest race lap will be right up there with pole, or even a touch quicker.

I definitely don't have any more love for that final sector than I did when F1 ran here in 2007-08; McNish certainly didn't sound enthused with it either. Not to mention, all that width, and still, so much trouble with traffic in that section.

[TF110]

Its a twist to a straight forward track. Climbing back up in the final sector to set yourself up for a good run up the front straight. Definitely challenging and there's a good amount of time to lose or gain in just the last two turns.
