Bathurst City Council seems to think so. Recieved an invititation to re-book my campsite for 2013 today.
Dates are Feb.8-10th
Maybe it's time to start a B12 13 thread to post our suggestions?

My son and I have been watching the 12 hour again tonight, and have been discussing how bad the TV commentary was. Real amateur hour stuff. It's been mentioned on other forums, but a high priority next year, for spectators and the TV coverage should be to get John Hindhaugh and the Radio Le Mans team down here for the race. Apparently, they were keen to come out this year and had the budget sorted out, but were turned down, for whatever reasons. Sorry Richard if you're reading this, but mispronunciation and just plain getting names wrong of some of the top sports car racing drivers in the world just doesn't cut it.

Just to set the record straight, the straight line speed diff between a current F3 and the top speed of "that" Ferrari is about 10kmh.

Oldtony · 13 Apr 2012, 23:58 (Ref:3058669)

Interesting Efi.
Is that worked out on rpm/gearing or speedtrap times?

Has the 2013 date been confirmed officially ?

Data is only as reliable as it's source.

EfiOz · 15 Apr 2012, 20:56 (Ref:3059860)

Knowledge, mostly.

pretty sure it is around 10km/h difference

He did 10km/h

By all means invite John Hindhaugh etc.. down as guests to compliment the local callers (like Channel 7 used to with Neville & Richard Hay)

But what sense is there to use a completely foreign commentary team to commentate a race that is primarily Australian? The majority of entries in the lower classes were Australian, the TV coverage was geared towards local audiences (with the live SpeedTV Australia coverage etc...)

Also remember that the trackside PA commentary was the same as the internet feed & the SpeedTV coverage.

If you've listened to RLM before, there's no comparison. They are the best at what they do.The B12 organizers are pitching the event at more overseas entrants, so it makes a lot of sense to get a commentary team that prospective teams respect. It also internationalizes the race by having the best in the business covering the race. I don't know where the money comes from, but I do know that RLM are pretty tight with Audi, so I'm making a guess that Audi/Phoenix would have been forthcoming with the dollars to make it happen. Although the race is still primarily Australian, Audi certainly gain a lot of exposure from their B12 wins in overseas promotions. Hindhaugh and company are quite capable of covering a field of 30 or so cars, when they regularly do races of much larger fields in multiclass racing overseas. I really don't think that the AusSpeedTV audience would be that fazed by having some experts covering the race over the local hillbillies.

MM will need to change their ad for the 458 GT3

St00ge · 16 Apr 2012, 13:09 (Ref:3060205)

Radio Le Mans guys did stints on air for Speed during the Rolex 24hr at Daytona earlier this year.. They were quiet good, I'm sure they could manage with a few new Australia names to deal with and heck just let them broadcast their own audio stream if you wish to keep your local commentators.. Great "free" international exposure for the event by the guys who pretty much cover every major enduro event, seems too silly to pass up..

I was told by an F3 car preparer that the F3 cars were doing 245km/h down Conrod.

I would have thought that a good GT car would be a lot quicker than 255km/h down Conrod. Hell, i did that in an XU-1 Torana!

**GTRMagic** · 17 Apr 2012, 05:00 (Ref:3060680)

Isnt the question more around sector times than top speed? The video of Mr Gilmour's lap had him on the limited for a fair while in different places, with different gearing the top speed may have changed, but so would the speed the car had to get to that top speed...

A V8 Supercar can apparently hit 294km/h down Conrod, but it too can sit on the limiter a'while down the chute. A question would be ois how a 50km/h disparity in top speed translates into an almost identical laptime..

ForumNick · 17 Apr 2012, 06:00 (Ref:3060691)

well... with roughly 50% of a lap climbing up the hill & 50% coming down...

taller gearing gives you a higher top speed, but less 'grunt' to get up the hill...

lower gearing gets you up the hill quicker, but results in a lower top speed...

QED!

What do I win?

Corner Speed.

I read somewhere that the GT cars is 10 or 15% faster across the top of the hill.
Although they are slower down Conrad they carry much higher corner speed.
F3 car would be very much the same.

rich07 · 17 Apr 2012, 11:30 (Ref:3060868)

I remember Lowndes saying the Audi hit 270kph down Conrod last year.

Oldtony · 17 Apr 2012, 11:39 (Ref:3060872)

Aero of course has a very significant contribution in terms of the straight line speed v laptime trade off.
Downforce=drag. (more or less)
F3 has greater downforce than GT3, which in turn has more than V8SC.
My thought was that the power/gearing/downforce/drag ballance of the Ferrari would have given it a far higher difference in speed trap readings than the 10kmh quoted.
Are there any sources of data available to demonstrate how much and why?

that sounds unrealistically slow to me?

last weekend (at the same meeting that the F3's were running) Neale Muston managed to be doing 277Km/h in his 997 cup car (and he was nothing like flat though the chase), I find it hard to believe that a current Audi R8 GT3 would be slower than this.

I agree, I would suggest an un-restricted 458 would be closer to 280-290Km/h.
from what I know of F3 cars of that age, typically ~155Mph is the terminal velocity (~248Km/h)

agreed, the figure given of 10Km/h I regard as tosh.

Hard to say without seeing the data, but I would be surprised if the F3 cars are not at terminal steed up the hill too (we were touching 240Km/h before turn 2 in the Lotus), and I am dam sure they are not having to brake anything like as hard as we do to make the turns.

alfacors · 17 Apr 2012, 13:01 (Ref:3060914)

When watching a side by side video of Lowndes' Commodore vs Gilmour's Dallara, they are fairly even on the run into Hell, the Commodore gains going up the Mountain (5L V8 vs 2L 4) and actually gets to Griffins Bend marginally ahead, however the F3 pulls roughly 3 seconds from coming out of the Cutting down to Forrest's Elbow, the Commodore obviously has a highly terminal velocity down Conrod, but the F3's late braking and corner speed means by the time they cross the line, Lowndes only pegged back a second or so down Conrod. A lot of the time in the F3 is across the top, and also carrying speed into the Chase (roughly 70m mark for braking).

Simon S · 17 Apr 2012, 13:43 (Ref:3060933)

got a link to the F3 onboard? (not seen it anywhere)
