Does anyone have any photos of an A9X going down the production line? Or photos of what Pattersons did at their workshop?
Cheers

How about an SS with a 253?

Cheers Grant for those photos. Geez they look good don't they. Not the pictures I'm after though, here's why. I'm in a bit of a debate on another forum (IPRA) about wether the A9X had a bonnet hole and that was the way Holden delivered them to its Dealers. The rule makers in IP do not allow bonnet holes for A9X as they believe the road cars did not have them as delivered by Holden to the Dealers. That's why I ask if there is a photo in existence of an A9X at Holden's prior to delivery that show's the hole. Any other supporting evidence would help.
Maybe I'm raking up the wrong tree and they didn't have them?. Would love to know though.

Cheers

What a frOcking wank (sorry) WTF is the scoop without the bonnet hole lol.

[A9X]

You shouldn't have too much of a drama, the A9X was sold with the scoop as an aid to cold air induction, ergo it must have a hole.

There will be a homologising document in place, perhaps Red can help you

Homologating, friggin auto correct

Homogenising lol.

Hi Again.

The A9X is a good example of what has been done by the factory.

Remember that a stock road going A9X should have a plate to block off the air hole. These plates were introduced after the cars left the factory, when the problem was found. I think from memory they used the excuse of water entry. If it just has a standard air cleaner & the hole is left open, you most certainly will an overheating issue at speed.

When the scoop & hole are utilised on the track, a cold air box if fitted around the carby & sealed to the underbonnet with foam. This way only cold air enters the carb & the air flow thru the radiator is not reduced.

It's amazing how increasing the air pressure under the bonnet has such a huge effect on the radiator air flow. Undertray & spoiler & radiator air intake design is one of those areas that has improved greatly on late model cars

From the A9X parts manual.

[ls2lxhatch]

You may need to send Dr Terry a pm. The post I quoted was written seven years ago.

Dr Terry indicates that the cover plate was introduced as an afterthought to fix cooling issues with A9X road cars. It was probably up to the dealer to drill the holes and mount the plate if required.

I think the cover plate was also required for rego in WA as at the time WA did not allow rear opening bonnet scoops. There may have been other states that had the same requirements.

Thanks to all that have replied so far. As a passionate Torana person I felt that it is wrong that a category of racing does not recognise what is commonly accepted by all others outside of that group. How would The Baron feel if he turned up with his A9X to go racing and got told to cover the hole!! WTF would an appropriate response!!

As I mentioned before, if anyone has paperwork or other evidence, it would really help?

[eyepeeler]

That's brilliant Darky. I will PM my email address. That just might be what is needed to get them to sit up and look.

You know, I have thought the same thing, Ford people!! Their not really, but rules and regulations seem to dominate right down to nuts and bolts.

Hi Dave, interesting you got a defect notice back in the day. What did you say to the cop?? One bloke from WA on the IP forum knows of an A9X sold new in WA that had no hole. At least that is what he says. Do you know what ADR number covers this particular issue? It might be years ago, but do you remember if the cop told you what ADR you violated?

i could ask my bro

there is no restriction to getting fluid on the windscreen
5am in kellerberrin and 50 kph in town
the cop waved me over and
was walking back to his patrol car for his sticker
and infringement books before i had even stopped!
prick grabbed the only hose on the carb that was not secured properly
hole in the bonnet
8in hotwires
didn't have the heart to tell him the rears were tens
only needed 3 things in those days for a yellow lickie
didn't even know what adrs were in those days!
good luck with your ipra cause!

Found some pages regarding the A9X bonnet scoop and bonnet holes in the engineering drawings i have.

Here is the main page showing the bonnet scoop, the bonnet hole , and the block-off plate. This page was used in the A9X parts supplement, as shown above. Were road cars meant to get the round hole in the bonnet while the race cars got the bigger rectangular hole?

This is a page i found in some paperwork sent to Allan Grice as a package to upgrade L34s to A9X specs. It's a little hard to read but all the important dimentions are there.

Here is a page i just found, it shows a preliminary idea for sealing the air cleaner to the bonnet. Note the date and the page title in the title block for the page at the bottom (77 styles means hatchback). Looks like they had the idea for a bonnet scoop early on but it didn't make it onto the L34.

Wow Grant that is some excellent drawings you have. I see that is dated 1974 for the LH L34 but for the 77style which is hatchback as you said. Unreal stuff.

[V-SLR5000-P]

Sports Car World road teast on A9X hatch NSW reg JNO-652 (August/Oct 1978) states :
"on the tset car the bonnet scoop wasn't scooping anything, it was a dummy, with a blanking plate where the air access hole into the engine bay should be" the report also said :
"if you see one for sale, buy it. Don't even hesitate. Even if you hate driving it - which you won't - you will have bought a classic car that wii be worth a fortune in 20 years time."

[LXM21]

Mine has the screw holes & can see a slight outline where the rectangular plate was once fitted.
