Guys with the compliancing ive been requested to provide maximum factory power hp option engine for lx/lx torana including ss slr l34 and a9x. Whichever the highest is i need that figure to provide and the reference source to provide to the engineer for lb1 or lb2 compliancing basically i need to work out if my engines ho is within 20% of max factory option. I believe it is at this point.....

Going to be tough nailing down the performance of the L34 option, you could get a high out put option package which took them to just over 300 horses. You'll get many varied reference sources on that one because they were from the dealer but a Holden part.

Theres a few gurus out there...but while we wait...wasnt 240hp the number.. even for L34s? And I thought the L34 HO was specifically identified as not for road use as it didnt meet pollution rules.
Maybe at 10hp more for LX.
Like I said...wait for the gurus.

Lx was the lowest.
L34 the highest, like previously said, the l34 high output is the one, if you can find an actual number.

[LC-GTR-1969]

Wasn't the A9X just the same as the SS engine spec? L34 had the good breathing engine that made the berries. I thought the HO versions were 280hp and the normal l34 about 240hp, but thats just from reading shyte in old magazines through the years- doesnt make it correct.

[ozyozyozy]

Holden homologated the hot engine for racing for torana with the LH, so there was no need to fit the hot engine to the a9x.

Thanks for the info guys. how ever it is all general info without documented reference.

 

THE general figure that pops up in in 1974 wheels magazine ( yep an original pair of magazines ) and 1974 sports car world mag and gregories workshop manual that i now have is a figure of 240bhp.

There doesn't appear to be any variation to this figure in publicised writing anywhere that I can find.

 

This 240hp figure I would assume would be rear wheel hp figure too yes ????

 

I was hoping some of the esteemed genuine owners of a9x l34 and the like, may have documented evidence.

The horsepower figures from GMH were taken from an engine dyno and are SAE net figures. This is the engine with all ancillaries including full exhaust, as opposed to gross figures, which are measured without the water pump, alternator, power steering, exhaust, air cleaner, and may even include revised timing and fuel mixtures. The L.H. workshop manual must have horsepower included in the specs.

Theres plenty of original Holden sales literature available that states the figures. Just hope your engineer will accept that the 240-250hp is RWHP and not as above..

Hmmm. I'll have to dig that pamphlet out so I can have a closer look at that motor. Did all LH come out with the single outlet water pump or just L34s?

[myss427]

I was told early LH had the single outlet.

seen a few on cars in sold section of aust musclecar sales

good original early lh slr 5000 

[hanra]

All V8 LH's. There is no need for the second outlet.

[308 Sunbird]

And pre July76 LX v8's as well.

[Shiney005]

Rightio then. This forum continues to teach me stuff every day. Love it.

Yes 240hp is what i always remembered, its a flywheel figure....no way its rwhp.

[Shiney005]

Not to mention that it was a pretty optimistic figure as well. The same horsepower as a VR Clubsport? I don't think so.

[Dr Terry]

It's not common for car manufacturers to quote RWHP. GM-H always quote flywheel HP & in those days it was a 'gross' figure.

 

The highest figure you'll find in official literature for a 308/5.0 V8 in an LH will be 240, even though the std motor from around Oct 1974 onwards was the HJ version which had 250 bhp.

I have only just bought your book and haven't had a chance to read it yet so stop me if I have got this wrong, but how could the VR/VS motor (180 kilowatts) be rated at less horsepower than the HJ 308?

As has been said many times on this forum when the topic of HP comparisons with older cars raises its ugly head, prior to around 1976 Australia used GROSS HP figures.

 

After that they used NET HP figures, which are vastly different & cannot be compared.
