Seem Ford reserve to right to ask questions later. JW on the other hand is still banging on about the change. The difference between being professional and just a kid throwing his toy out of the cot.

It's punch for punch IMO, after Rushbrook's comments earlier.

Have they done anything to the circuit since the series last raced there?  New pavement/resurfacing?  Tweaking corners?

Just the 12m addition which was implemented for the 2019 event:

This weekend they run on the new softer tyres, opposed to the 2019 spec.

Practice 1 starts at 11:15am track time.
Qualy on Saturday, followed by a Top 10. Same for Sunday. Race start at 3:20pm both days.

There's the best photo of the Camaro aero adjustment. Wrapping the front of the wheel arch.

Still some conjecture over engines.

I'll have a look for highlights at some point if they are out there. I'll be flat out for the weekend at Island Classic which is a huge event and well worth going to if you happen to be in Vic

Was going to head down as crew for the '77 Bathurst pole sitter, after finally ducking and weaving to get it within the period reg's.
Decided against it as the chance of rain and a 6mo wait on wet's became apparent!

Enjoy the weekend!

For the sake of cleanliness, you can remove the "ZL1 1LE" from my manufacturer/make in the current/approved teams table.

anyone want to take a punt on what the changes will be between the Sat and Sun race while they are still figuring out what the cars are supposed to be?

Don't think there'll be anything overnight. I fully expect if before the AGP though.
Really looking forward to the weekend of racing. New cars and potentially a new status quo, hopefully earnt and not some parity debate!

I'll make 11 .

And a minimum fuel drop too, for the overhead cam setup, similar to how Nissan struggled with fuel.

https://www.speedcafe.com/2023/03/03/newcastle-500-fuel-drop-comes-to-light/

Where does it say "for the OHC setup"?

It doesn't.
Whilst all hearsay as we don't know the Ford's exact configuration (especially ala VCT), typically the DOHC setup uses more fuel. More cams to rotate and higher engine speeds = more resistance and more fuel.

It's been pretty well documented that both Nissan and Merc had efficiency issues (both OHC engines), quickly followed by driveability issues (as they leaned them out, especially low RPM out of a corner, where the pushrod excels).

Happy to speculate and give my thoughts that it's the Ford donk that'll be a little thirstier, given the above, also happy to be proven wrong - something Supercars will likely not disclose.

4 valve, OHC is actually more efficient. It can develop more power and torque for the same amount of fuel. If it has a consumption issue it is from Supercars tuning.

Yes more power and torque, but arguably more fuel. Still comes down to more cam friction and engine speeds.

https://www.designnews.com/automotive-engineering/tech-tidbit-why-%E2%80%9Cobsolete%E2%80%9D-pushrod-engine-design-better-modern-overhead-cams

Just my thoughts based on the troubles that Merc and Nissan had - the origin of the fuel drop.
As you say, Supercars maps are their own thing and the VCT within that unknown as well. I dare say we'll see some tweaking as the year goes on, we've already seen 2.

We don't even know what block the LS is using. It's widely considered to be the LS3, but I can't see any solid confirmation on this?
9news list it as an LSX, which is completely off the mark, we know the Gen3 is aluminium and not cast iron. This also wouldn't explain the supposed 60kg advantage over the Coyote.

Biante are re-releasing the 2020 Bathurst winner. Classic did the last version, fully sealed and not great.
After receiving my Biante WAU winner, I don't think I'd be rushing for the 2020 upgrade, especially at the price point.

Using tapatalk most of the time you don't even see the numbers.
Unsure why you cop the heat Albert, you're one of the good ones who actually provides conversation on here .

REM is still sorely missed.

Looks great!

It's one of the better Camaro's on the grid.
The Mustang's look far better in livery form.

So all the finger pointing aside, Supercars prescribing a mandatory test day (with official results) without a minimum weight or COG set, removing the rule for a green tyre hot lap at the end of the day and still tuning the benchmark for the Ford engine is OK?

We run better amateur hillclimb events.

Does anyone have a basic Camaro/Mustang livery template they'd be willing to share for the fantasy community?

I'd been using a ZB freebie from Penrite for a long time...

Unfortunately the Gen3 cars are basically the only two I don't have a template for

No stress Arrow. I'll see if I can find something similar ala a GT3/4 template. Might be the easiest way.
