Might have some (freindly) opposition there! I still reckon the A9X would fall into that catagory - even with it's detuned engine!the L34 was the last true supercar.

If the L34 had 100 more HP than the SLR 5000, then it would be impossible for the 5000 to beat it in 0-100km + 1/4 mile times
But beat it they did. The early racing L34's were only getting just over 350hp, 340hp factory delivered is fantasy.

Anyone who thinks a stock L34 was putting out 100HP more than a stock 5000 is dreaming. Headers on an L34, has anyone seen them? They are very basic because the rules allowed exhausts to be free past the first join. Race cars were putting out around 350 to 370 (370 for the best teams). With the A9X race cars they were pushing just over 400. Anyone who has had all 3 cars in original form will tell you there isn't much difference.

Fair enough, they would have had more than 240Hp though, or else what was repco engineering doing to them? (nothing), i do have a book though that states that the full option HO pack produced 370HP, but i havent read anything that states the standard L34's REAL power output.
They didnt have proper headers , they had that join so you could bolt up custom extractors, (mini headers i spose), but thats better than a standard exhaust manifold.
I read that HO statement in aussie muscle car magazine - the one with the L34 special.

From AMC issue 15 Quote " With full balancing and blueprinting, a full race exhaust system etc, the HO package was claimed to boost the base L34's 240bhp @ 4800rpm to around 350-360bhp @ 6000rpm." unquote. It's obviuos they are talking about race cars.
The HO package did not give you a full race exhaust, blueprinting or balancing. Everything was bolt on bar the "Bathurst" cam (which obviously required cracking the engine open) as it was done at the dealership.
As for what was Repco doing to them, they were making them strong enough to race, homologating the parts for racing, in stock form, the car was choked by the exhaust to bring back the performance due to the supercar scare.

I stand to be proven wrong. 
BTW, thats a pretty good write up about L34's in that mag hey. lots of good info and stunning pics.

Nah flywheel horsepower...
I a big fan of the L34, But A9X's are awesome too, just pissed me off that they released the ADR rules and couldnt use the L34 engine.
Me mrs' old man used to own an L34 and he said it used to kane, thats why i couldnt beleive these figures saying that the slr5000 was quicker, he said that no car could keep up.
But im not in a position to argue, im not going to embarress myself any further.
<<Damn i love these animated smileys

were they both stock? cause then im right about having 100 more HP.
we should get someone that ownes an L34 into this discussion, then we can get some facts strait.

Well thats what ive always known. Holden didnt keep the L34 hush hush for no reason!
I actually only found out the other week that holden didnt do any mods to the a9x engine, they couldnt use the l34 engine so they just smacked a standard 308 in it - slack arses, they spent all that time making a good race car but didnt give it any power.
Look at the brock bommadores, didnt the group 3 have like 400 horses?
But i spose the RACING CARS didnt need to comply with adr rules so they all smacked a l34 engine in their a9x's when they got em and worked from there.

most of the a9x race cars ran l34 engines, a9x 308 is dead stock no special cam only diff engine fan. as if holden would brag bout hp figures 4 a l34 there was a shit fight going on, dont get me wrong a9x is a gr8 car but sorry no muscle car in stock form. before i get roasted check it out yourself a9x engine is same as a hz kingswood

I haven't owned all 3 cars myself, and for you to produce dyno figures would have to have been done back when the cars were new (and untouched), otherwise you don't know whats been done to them. I do however have a friend who has owned all 3 cars in stock form, when they where new in some cases and near to new in others and from what he tells me, the L34 wasn't much quicker than the A9X, and after a few laps around a track, the A9X would catch the L34 anyway. Magazines of the day were testing these cars, I even have the L34 against an LH SLR5000, I've already quoted the figures they got.
Considering you lose around what, 30% from engine to rear wheels, I doubt very much the L34 would have 220rwhp and the A9X 140rwhp on the same dyno. The fact is, the L34 needed bugger all to make it go harder, a quick exhaust change would do it.
As for the A9X being the same as a HZ engine, it's actually not. The cam is in fact different in an A9X to a stock 5000 or SS.
The A9X race cars didn't use L34 engines, they used the homolgated parts from the L34 in the engines, lets face it, not too many L34 blocks would have been much good by then, and the A9X block ( and all those blocks of the era) were the same with the extra webbing etc.
No the VH Group 3 wasn't putting out 400hp, the latest GTS Commodores are putting out those sort of figures though, which is about what an A9X race car produced. It was a while before the race Commodores were able to produce the lap times the A9X was doing.

Ok, i just had another quick read of my "how to rebuild and hotrod holden v8" book, ( awesome book i reccomend everyone to buy a copy, best book i have.
anyways heres some quotes and information.
"Early testing of the (standard) L34 engine on the dynomometer proved that the engine was on the right track. Horse power varied between 300 and 320 horsepower and the engine would successfully rev to 7000 rpm."
5.0 litre - red option L34 High Performance Package
Blah Blah Blah
Power output : 260kW (350 bhp) @ 6000 rpm
Torque : 400Nm (544lbs/ft) @ 3000 rpm
"A9X power specifications were not released to the public as it was deemed that public opinion would be negative to a registered road car suitable for race team development for the race track. This was similar to the L34 high output option for the LH.
The standard A9X engine was the blue block with performance heads, modified intake manifold, ignition as on the L34 and an exhaust system similar to the L34. The A9X was a better handling car than the LH, due to "radial tuned suspension".
Touring car racing and bathurst homologation allowed A9X Toranas to run the L34 ngine and L34 improvements. Race teams worked on the fuel and exhaust systems and eventually increased the horsepower to 395 - 400."
Well looks like the A9X did have modified heads and should have gone just as hard as the L34. There are no A9X power figures in this book, only the L34 HO.
Well thats enough typing for tonight.

Yeah i know, but it makes sense, how can you get 400HP out of a 308 without modifying the heads at all? all the race teams did was tune the carby and exhaust and cam.
it also says every other lx engine is the same as the one in the HJ.
