Bathurst 1000 on Speed!!!

[Shannow]

Nothing on the TV gives credit to the track.

It's a public road, through some vineyards and stuff, and we drive it a few times a year.

It's a serious climb, and the dipper is exciting enough at 60km/hr (the speed limit).

As to Hillclimbs, the Bathurst light car club do hillclimbs both ways, up the normal way, and starting just at the start of Conrod, and heading backwards up the hill...first port of call the wall.

Also do sprints, starting at the clubhouse (you see that just near the start of Conrod, down through the chase to the start/finish line.

It was a great race; I wish I'd been able to watch the entire event. But I enjoyed the last hour. I too was prepared to be put off by ol' DW, but I thought he and Mike Joy did pretty well. They seemed to have done their homework and I think they had a great time, which helped the broadcast. Good on them.

DW's ride along was hilarious. Channel 7 has the whole thing on their webpage, so funny.

 

[A_Harman]

My TV was tuned to Bathurst at 7pm, and stayed tuned for the F1 race at 2am. Total racing heaven all night long. So I lost some sleep, that's what Sunday afternoon is for.

I noticed that a couple of cars were showing Valvoline sponsorship. Does that mean Valvoline is widely available in Australia?

I thought this was one of the coolest things from the race - this guy was checking his brakes coming into every corner!



DW was saying any race car driver who's ever lost their brakes will do this all the time in any race they'll drive in the future.

 

[A_Harman]

I give my brake pedal a couple of light pumps on the straight before a big braking zone. There are a couple of reasons for this: it collapses any bubbles that might have formed due to boiling of the brake fluid, and it compensates for wear of the pads that occurred in the previous braking zone. A couple of confidence taps makes the feel of the pedal consistent and gives you time to make other plans if the pedal doesn't feel right. I've played the scene where the brake pedal goes to the floor right at the entry to Turn 5 at Watkins Glen, and prefer not to repeat it.

 

[Drew99GT]

Yea, doing 200 mph down a straight away and having the brake pedal go to the floor would make for a suck day.

Yep, it's in every auto parts store, and most supermarkets. Most commonly in 20W-50, but 10W-40, and 15W-40 are taking up a lot more shelf space these days (saw an xW-60 the ither day IIRC).

9AM to 12 Noon used to be full of John Laws (the Golden Tonsils), stating "People who know use Valvoline...you know what I mean"...he's the jedi in the background. (The other guy used to be Captain of Oz Cricket Team)

 

[hooligan24]

Anyone catch the incident where the team changed drivers and in the mix they lost the radio, the drivers didnt know they had changed brake pads. At the end of the straight away he didnt have a pedal cause he neglected to check and pump the pedal. gas tank ended up rupturing and pouring fuel all around the wreck and ended up on fire all around the car. was another edge of the seat moment waiting for him to climb out.

Yes, I was almost startled at how well ol' "boogity boogity" redeemed himself during this broadcast!! He actually sounded credible, and YES they MUST have 'coached' the h**l out of him!
(See DW, there IS more to life than driving a Toy, and turning left.

)

But anyway, that is THE most wicked circuit on this planet, The 'ring included!!!

(I used to think that the old, long gone, Bridgehampton circuit was something else!)

That is also the way racing is supposed to be (you Ozzies do it up!!), especially those last 10 laps or so.

I love floor shifted (NOT steering wheel 'paddle') manual sequentials.
Shannow; do you know which brand most of them are using (Emco, Quaife, X-Trac, other??)

I wonder how these cars would compare, lap time to lap time, with the same driver, on the same circuit, with the DTM machines??

(Yes, I know that there are MANY differences; displacement, allowed technologies, etc.)

 

[Shannow]

dd, gearboxes are Hollinger (Oz brand). Rear end is 9", locked spool.

They use super short deck height small blocks, to keep weight down, and low, and to match the mandated rev limit of 7,500RPM (although I've seen them spin to 9,000RPM on downchanges using engine braking).

They run E85 ATM.

Thanks!

(Of course, it was the only brand I did not mention.

MANY road racers here in the states use these as well.)

Do you ever think that the rule makers will allow at least Detroit Lockers, if not Torsen type, or high tech clutch pack type limited slips??

Even though they are only spinning to 7500, they still sound GREAT!!

Gran Turismo 5 seems to indicate that the V8 Supercars are a bit quicker; about 2 seconds per lap at Laguna Seca, and 2.5 at Suzuka. The cars are older and of different model years, but it doesn't look like much has changed in either series since then. I also ran some laps with a 2010 Sprint Cup car. It ran similar lap times to the V8 Supercar at Laguna, and was about a second a lap faster at Suzuka. It's unlikely you'll ever see them all on the same track on the same day with the same tires, so this is about as good of an estimate as you'll get! It really is a good simulator. The driving physics are all there. Here's the relevant info and my best lap in a five lap trial:

2004 Audi A4 Red Bull DTM
This car had multiple wins in the 2004 and 2005 season.
475hp@7500, 386lb-ft@5000, 1080kg, 4.0L V8, 55F/45R
Laguna Seca - 1:27.4
Suzuka - 2:04.4

2000 Ford Falcon XR8 V8 Supercar
This car scored one win in 2000 and claimed pole position at the 2000 Bathurst 1000.
626hp@7500, 480lb-ft@5500, 1350kg, 5.0L V8, 57F/43R
Laguna Seca - 1:25.4
Suzuka - 2:01.9

2010 Chevrolet Impala DuPont Sprint Cup Nascar
Jeff Gordon's car.
871hp@9000, 552lb-ft@7000, 1565kg, 5.9L V8, 55F/45R
Laguna Seca - 1:25.5
Suzuka - 2:00.9

Hard compound racing slicks were used for all.

Maybe this will help the comparo, admittedly 1996.

Since they worked out how to run massive negative camber on a solid rear end, not sure that they will want any sort of differential out back.

Lockers are strange, as the drive wheel changes on over-run and acceleration through a corner...they were homologated in the touring car days of the early 70s.

DW talking to our guys.

 

[A_Harman]

I heard on the broadcast that the V8 Supercar-of-Tomorrow will have independent rear suspension. It's nice to see them migrating to more modern technology. NASCAR is finally getting one foot out of the automotive stone age next year with EFI. Don't ask when they'll allow IRS or transmissions with more than 4 gears.

OK, so that's how they do it without having to 'drift' through every corner due to the spool. Got it!
