No doubt this has been asked before.
Without me searching everywhere to find out, what is the maximum legal engineered engine size for a LH Torana sedan in NSW ??
Does anyone know what a LH SLR5000 weighed ?
Thanks
Lh Torana Max Engine Size?

Published figure is 1183 kg's. Yella needed to go over the weigh bridge because it looked too phat, it blew 1300 kg's on the scales.

Thanks. From what I can work out with RTA modifications to light vehicles its original vehicle weight X 0.294 for naturally aspirated engines.
Using 1183Kg that only works out to 347.8 ci

When i inquired at the RTA some years ago it went on the original engine capacity so with a factory 253 i could go a max of 354 cid, so the max will be less if it was fitted with a 202, rules may have changed but thats what they told me, goes on percentage of original engine capacity, after that you need engineers.

My LH SLR 5000 was 1300kg on the weigh bridge. No flares.

The NSW rules are different to the NCOP, under the NCOP slightly larger engines are permitted.
The NSW rules for weight used in the calculation is as follows.
'Original weight� is the original (unmodified) �tare weight� of the sedan version of the vehicle model fitted with the largest engine available for the model but without optional accessories such as air conditioning and tow bar.
http://www.rta.nsw.g...ns_nov_2007.pdf
Sedan
Kerb weight: 1143 - 1183 kg (2520 - 2609 lb)
The means you can have an LS1 346 cu in but not an LS2 364 cu in.

According to the NCOP it is 6.3L in ACT as we have the SLR 5000 listed as 1275kg's which is a fairly accurate weight.

I'd run with that figure. Just check all my books but they are vague/silent on weight.
Spotlight on LH/LX Torana says 1143 - 1183 kg's (depending on model), but from memory, the registered weight of my 2850 LH SL was 1183kg.
Even the Owner's Manual is vague on the V8's, only mentioning the kerb weight of a 6 cyl. SL/R sedan as 1204 kg's, or 1613 maximum loaded weight.
Holden Torana Performance Handbook gives hat and hip room dimensions, but no weights for any models???
LH Holden Service Manual - 1183 kg's for again, only 6 cyl 4 Door "SL/R".
As above, I know for a fact that Yella is 1300 kg's, because I had to weigh-bridge her for rego, and that is what is on the rego papers.

I'd be very interested to know if the LX Owners Manual has V8 vehicle weights. Seems like only the rego office use such info.

The LX owners manual I have does not mention weight.
Details from Holden hatch brochure.
https://cache.gmh-to...ch/brochure.jpg
SL 1183 kg (2610 lb)
SS 1213 kg (2674 lb)
I guess that the SL weight is the 6 cyl and the SS weight is the V8.
My WA rego papers for the hatch list the tare as 1204.

^ yeah, I wouldn't be so sure about the V8 weights. For whatever reason they seem to quote the six cylinder weights only. Might be a bit similar to my HSV, it uses the standard Commodore weight to keep it in the lower rego bracket (a dealer thing).

Ive just found my copy of the NSW RTA Light Vehicle Code of Practice book. Its dated Jan 1994. In the back it has a guide to typical weights of vehicles.
1974 LH SLR5000 Torana - 1205 Kg
There is no listing for LX Torana's or any other type of LH.
So therefore using this weight it means you can register up to 354 ci.

Actually I thought the rules had changed to limit engine size more, but, my RTA book from 1994 still lists formula as original weight x 0.294 which is the same as what it is now.

All the documentation would tend to indicate that 1205 kg is for a six pot Torrie. You could use the ACT figure as precedence.

You are probably thinking of the new National Code of Practice for Light Vehicle Construction and Modification (NCOP). NSW still hasn't adopted these rules.Actually I thought the rules had changed to limit engine size more, but, my RTA book from 1994 still lists formula as original weight x 0.294 which is the same as what it is now.
NCOP
Have a read if you have a spare few hours
. The NCOP rules actually allow you to run a larger na engine. You multiply the vehicle weight (kg) by 5.0 to get maximum engine ccs. With a 1205 kg LH you can fit a 6025cc engine. Yella, the RTA's documentation on vehicle weights actually specifies the LH SLR5000 fitted with 308 cu V8 weighs 1205kg.
I reckon Redslurs 1275kg is closer to the mark in terms of weight.

^ I agree, there is no way an SL/R ever weighed 1205kg, that's got to be just plain wrong. When I got mine weighed, there was a fault with the fuel guage, and it still had about 30+ litres in the tank, even though the gauge said empty. On that basis, 1275kg is much closer to the mark.
The weird thing is it isn't documented in any of the historic Holden documentation, only reference to the six pot. Weird but true, check out the documentation for yourself.

Move to NZ and you can put an 500 cube alloy big block in one if you wanted.Thanks. From what I can work out with RTA modifications to light vehicles its original vehicle weight X 0.294 for naturally aspirated engines.
Using 1183Kg that only works out to 347.8 ci

Yella I have no doubt you speak the truth. Record keeping hasn't always been a high priority. As you know it works out cheaper to register your car if the vehicles weight is under represented. No-one is going to go to the RTA and say your records are wrong my car is heavier than you think, I should be paying more for registration.
I have attached the page from the appendix. There are probably many more inconsistent weights for many of the old holdens listed. But someone back in the day pencilled in a figure on a new vehicle compliance sheet and that has now became fact.
There was a similar discussion in the drag racing forum some time ago regarding vehicle weights and how the "offical" LH/LX weights seem inconsistent. Has anyone weighed their stock SLR5000 and would like to share what they found?

Yeah the HSV is understated for rego reasons as well, but when it comes to maximum engine size under the national light vehicle code it does make a difference, which relates to the original question asked.

Yeah I agree, we need an original LH SLR5000 on a weigh bridge and see what it comes up with. I took my GPAK over the weighbridge here, I'll see if I have an old rego paper...................
Yep just found it, mine weighed 1300 KG.
But thats without the original fuel tank and a plastic fuel cell installed and with a chassis kit. But also probably a lighter gearbox in the 2sp glide. But then again a 9" diff probably adds a bit but probably evens out ?
Gotta be more than 1205 KG though. I'll just show the engineer my old rego paper with 1300 KG on it.

This is the Holden Hatch brochure.
LX Hatch
SL 1183kg
SS 1205kg
I have also seen kerb weights of 1143-1183 quoted for the LH/LX. I think it is reasonable to assume the following.
1143 kg 4 cyl
1183 kg 6 cyl
1205 kg V8
It would be interesting to weigh a 100% original SLR or SS and see how it compares.
The tare would have been provided by Holden when the car was complianced. I would think that the only way you could get the figure changed from the published weight of 1205 would be to get a letter from Holden stating it was wrong.
