476kw LS9 HSV GTS-R....

[Chopped]

http://http://www.drive.com.au/motor-news/corvette-heart-on-the-cards-for-476kw-hsv-20150820-gj447t.html

"HSV is set to go down in history as the producer of Australia's most powerful muscle car.

Not content to fade away gently at the conclusion of Australian manufacturing, insiders say the brand is working on a secret project to send-off its locally-made Commodore flagship with the heart of a heroic Corvette.

While HSV officially would not comment on its future model programs, it is understood to be working on a project to ensure that the final Australian V8 will "go out with a bang" by putting together a deal to transplant the supercharged 6.2-litre heart of the discontinued Chevrolet Corvette ZR1 into what would be the ultimate Australian muscle car."


"Introduced in 2009, Chevrolet's LS9 V8 looks set to be the engine of choice as it is similar in size to the Camaro-sourced LSA V8 used in the current Gen-F GTS – unlike the current LT-series engines that may not fit under the Commodore's bonnet.

Producing 476kW at 6500rpm and 819Nm at 3800rpm, the LS9 would represent the most powerful engine ever sold in an Australian-made car, outgunning Ford's final 351kW FPV GT-F by an order of magnitude.

While fundamentally similar to the 430kW motor currently used by HSV, the LS9 features several key changes intended to produce more performance.

It has a 20 per cent larger supercharger, titanium con-rods, forged internals and larger intercooler along with a race-ready dry sump lubrication system that keeps oil in a remote reservoir beside the engine rather than in a pan underneath the block.

Experts suggest local know-how acquired while developing the dry-sumped 7.0-litre HSV W427 of 2008 could allow the LS9 to go to work under the bonnet of the last Australian muscle car. It's also possible that the Brembo-sourced carbon ceramic brakes of the ZR1 could reappear on the final GTS, pushing prices beyond $100,000.

The catch is that such a model would be a thoroughly limited edition. General Motors is said to have limited stock of the LS9 engine, which could result in less than 200 examples of the ultimate HSV being produced, making it a limited edition in the same vein as the HSV GTS Maloo."

All just heresay until it's confirmed but seems pretty likely imo.
Nice send off for the HSV fans.

I wonder what it will dyno....

Nah just kidding, let's not turn this thread into a ***** fest which will end up getting closed and cause the mods undue hassle.

[Revolver]

Wasn't the last Australian V8 the 308? Which was VT?

Or at the very least the AU T3 342ci Windsor. That was completely built in Oz.

Not just a crate engine bolted in and tuned.

[mcnews]

Wow. what a send off. That is mammoth.

[Grippy]

Hats off to HSV for this if it happens, will be a monster.

[Falcon Coupe]

Better to "Burnout" than fade away. Sounds great!

[Ford17]

Wonder what 476 HSV KW's will equate to at the wheels?

[sbutler]

476 will really be around 350 RWKW going by past HSVs

[Franco Cozzo]

GM Accounting, its got 476KW at the engine but just 275 make it to the wheels.

[bangm001]

Man I loved the VS GTS-Rs when I was a kid, best colour too! The VF HAS to be yellow, black massive wing and black wheels...

I reckon these will sell for two hundred thousand + like our final GTs.. Would be my pick if I was a holden guy anyway..

[sbutler]

The most expensive GTF is on carsales now $145000.. But there will be a cashed up bogen that will believe its the most powerful HSV & buy it, thinking he's the best.

Are you insinuating there's a more powerful or better HSV?

[FPV GTHO]

Would the current GTS driveline cope with the LS9?

[nstg8a]

I dare say it would at least get the ls9's gearbox as well

apparently FG chassis couldn't cope with a maximum tuned coyote, according to Ford PD. Something to do with the firewall being peeled away from the chassis due to the torque. Wonder if the VF chassis could cope with this level of power.

2 problems i see with that are the LS9 is only fitted to a Corvette, which has a transaxle and i believe the new ones are a 7 speed manual as well.

[HO 3]

Next years XR6T 310kw R Spec Sprint, or what ever they call it, should have it more than covered...........at least in straight line performance

Cheers Mick

[MethodX]

Stuff the naysayers.
Stick it to them GM.

The 253 (4.143 litre) was discontinued in 1985.
The 308 (5.047 litre) was reduced in capacity to 304 in 1985 to get under the Group A Touring Car limit of 5.0 litres.

The last locally manufactured V8 used in Holden’s ceased in mid 1999 when the imported LS varieties took over.

They were:
304 – (4.987 litres – 303.6 cu. in) in the VT SS & HSV Clubsport
And the stroked version
350 – (5.733 litres – 349.9 cu. in) in the VT HSV GTS

Purposed to be Australia's most powerful muscle car, not sure it matters where the engine was made. Half of Falcodores are probably made in China.

[Polyal]

Well I for one think the VS GTS-R is pretty cool so hopefully they paint it that LeMans Corvette yellow. Good on em.

[CyberWasp]

Take over 100kw off any figure HSV are claiming. They like to tell porkies.

Spot on!!

It means stuff all and its just a number on the piece of paper.

All that matters is who is faster and performs better.

[sexyxe]

While HSV haven't been known to have great engine numbers transferring to the wheels. What is the typical RWKW of a corvette with the same engine?

[Wretched]

I'm sure it'll still be a monster on the track no matter how good/bad it performs as a dyno queen.

[bangm001]

Doesnt matter about power guys, they will sell like hot cakes to the holden boys and as like the W427, we will hardly see any on the road street driven anyway.

[PepeLePew]

Ought to be a torque monster...nice send off!

[grey_esp]

IS the miami not completely hand assembled in oz aswell with majority aussie developed parts?

Drive must have just received their copy of Wheels magazine, it was all written up in that 2 weeks ago.
It does say it is still speculation and that the R8, R8 Maloo and Senator will be getting 395kw - de-tuned LSA from the GTS.
Base model Maloo, Clubbie and Grange to get 340kw LS3.

If it's not an Aussie cast block and crank etc. then it just doesn't count in my book.

[FalconXV]

Will the chassis need re-engineering for the extra power? Or is the GTS already rated for this? Also if it's limited run will that make it cheaper to develop?
