Thanks for all the info every 1 I'm feeling keen to finish the build.

Good luck with the build mate, let us know how you go with the engineer and engine size.

[Dr Terry]

To sleazy mate....Some proper documentation would go a long way.....

 

Cheers.

Sleazy !! That's a bit rough Bomber.

 

Anyway it took me a bit of time to locate this, so thanks for your patience.

 

As I said in the forward in my book I would only publish figures that I could back-up with official documentation, so fear not.

 

I couldn't find the official kerb weight in any workshop manual or service bulletin & you guys really had me worried, where the hell did I get this figure.

 

Finally found it !! In the original press release of the LC XU-1 in Aug '70 titled 'GMH News' serial number 70/27, the new XU-1 was announced along with most of the relevant specs. On the very last line on the last page is listed Kerb Weight = 2430 lbs. Using my metric converter this translates to 1102.22 kg.

 

I'm not sure how to post this on the forum, but if anyone has a copy of Fiv Antoniou's first book, it's on page 25 (bottom right).

 

I do have an original copy of this press release, so if anyone wants a copy I could fax or e-mail it to them, if it can help with any engineering issues. I'm sure any authority would accept a genuine press release on a GMH letterhead as proof of these specs.

Hi Dr Terry,

Thanks for the reply and taking the time to find the original document.
I would like a copy of the press release if that's ok, I'll pm you my email address.

The heavyest lc/lj torana was 1054kg. There was never one over 1100.

Where did you get the 1054 kg figure Bomber, even the factory LJ workshop manual supplement has the LJ XU-1 at 2417 lb (converts to 1096.33 kg).

Hey DJ, thanks for the kind words mate but alas I'm only human, so I sometimes get things wrong too.

 

Just to confuse the curb weight issue I'll throw this into the pot.

Looking at the CAMS Form of Recognition documents for the LC & LJ XU1 gives us different weight figures as follows:-

 

LC XU1 weighs 2270lbs or 1030.58kg (fluids etc but not including fuel or repair tools)

Fuel tank holds 77.28 litres x .711kg per litre = 54.95kg

 

1030.58kg + 54.95kg (fuel) = 1085.53kg - not incl repair tools (ie: wheel brace, jack and jack handle)

 

LJ XU1 weighs (estimated) 2310lbs or 1048kg (fluids etc but not including fuel or repair tools)

 

1048kg + 54.95kg (fuel) = 1102.95kg - not incl repair tools

 

So which curb weight figures are correct?

The curb weight published in the LC XU1 press release or the weight stated on the CAMS Form of Recognition + weight of fuel.

The curb weight for LJ XU1 published in the LJ Torana supplement or the weight stated on the CAMS Form of Recognition + weight of fuel.

[Dr Terry]

I noticed that one also, but the LC figure is probably closer to the mark, given that the tools etc. weigh how much ? Say 15 kg. That puts the CAMS LC total at around 1101 kg & GMH say 1102 kg. 

 

However the LJ is way out. The CAMS document puts the LJ 18kg heavier than the LC, but the Holden literature states that it was 6 kg lighter.

 

Maybe there was a revision to the 'official' LC figure for the purposes of racing.

 

Getting back to the original issue, I thought having a genuine GMH document showing a figure above 1100 kg was our aim & we now have that.

I just tried to pm you asking nicely for a copy of the press release, says you cant receive any new messages MR DR Terry.....

 

Cheers.

Yes, My inbox was full. Now fixed.

Agreed, having an official GMH document showing the weight figure above 1100kg is the aim.

 

I do find it hard to believe the official GMH weight figures regarding the 1970 LC XU1 being 6kg heavier than the 1972 LJ XU1 when you consider the differences between the two cars.

 

So the LC owners who want to engineer a V8 should use the GMH press release weight and LJ owners should use the CAMS Form of Recognition weight + full tank of fuel + approx weight of tools?

Any chance you can scan the press release and post it here, Terry?

We've just proved that 308's will be allowed, shan...

Edit: SHOULD be allowed, by law...

Hi Guys

 

I haven't forgotten Bullet, I just have to scan the original & then I cam e-mail it to you. My scanner has died, I should be able to do it by the weekend.

 

Dr Terry

[Bullet]

All good Doc, I know know you got my message, thanks again for the info.
I'm in vic on holidays so might stir up a few engineers while I'm here and put it to them.

Hi Dr Terry,
Any luck with the scanner? I have found an engineer that is keen to see the document and push the envelope so to speak.
He said if we can get it through it will open a big door for a lot of other people.

Cheers Bullet

Hey guys, well finally I received the press release yesterday, thanks again Dr Terry.

 

I'll try post it up latter once I download it onto my computer.

 

Cheers Bullet

OK, hear goes.

 

 

Seems to have worked, ya!

Holden did build and rego a LJ GTR V8 Torana,  The Lone o Ranger LJ GTR V8 Prototype, Vic Rego Number LGN307, was rego with a 308 V8 Engine on the 6/9/1972 by GMH Salmon st ,Port Melbourne at the Fisherman Bends Police Station in Port Melbourne, I thought this GTR should open the Door up for LJ's to have a 308 V8 ?????

[Bullet]

Hey Al, it may well be another avenue but I suppose you have to have documentation or proof of it.
I'd love to know the curb weight of that car, would of been well over 1100kg's.

Cheers Bullet

[xu2308]

24 lbs is on the Rego Papers for the LJ GTR V8 Prototype (LGN307)

I take it as 2400 lbs  =1088.62 Kg
