Holden Special Vehicles today unveiled a seven litre program at the Melbourne Motor Show, the last instalment of the company s 20th anniversary celebrations. The car to be known in its final development stages as the W427 is finished in the same Panorama Silver paint scheme as the original Group A SS VL Commodore, released at the Melbourne Motor Show of 1988, exactly 20 years ago.

HSV Managing Director, Scott Grant, said the W427 was a tribute to how far the company has come in just twenty years. To be able to produce a vehicle of these proportions is truly remarkable, Scott Grant said. The W427 will be quite possibly the fastest road registrable Supercar ever produced in Australia and among the quickest anywhere around the world, he said.

While power output figures are still to be confirmed, the W427 is likely to produce in excess of 370kW of power and 640NM of torque. It will also be one of the safest cars HSV has ever put on the road, Scott Grant said.

A new six piston front braking system will provide a 50% increase in pad area, while the W427 also receives a revised ESP calibration, six air bags, improved handling and new Magnetic Ride Control settings.

The W427 receives a bimodal active exhaust system to improve noise quality and back pressure management. Styling and design highlights include an all new front fascia, a three piece carbon fibre rear spoiler, 20 inch machined faced alloy wheel, unique exhaust tips and red leather interior.

Scott Grant said HSV would be introducing a unique customer relations program to accompany the launch of the new vehicle. The W427 will only be produced in limited numbers and we want to reflect that exclusivity in how we connect with our Supercar customers, Scott Grant said. This program will see the LS7 engine being fitted at Clayton, along with the dry

sump system and a range of other engineering features. We are looking at

opportunities to allow owners to visit HSV and view the unique manufacturing process that goes into building this car.

The W427 will go into production in the middle of the year and will be available for sale in dealerships in the third quarter of 2008. Make no mistake, while the specifications of the car unveiled on the stand today at

the Motorshow may change slightly between now and when production begins, this car is destined to make as big an impact as the original Walkinshaw twenty years ago.

Whoa, talk about "compensating"

shame the car still looks like arse, but each to their own i guess

EDIT: Just saw the coupe holden in the other thread, MUCH nicer... but still a holden

Edited by Yo-Yo

it just amazes me that in this day and age with climate change and carbon trading schemes set to go ahead with companies being able to ff-set there carbon foot prints e.t.c. here is another prime example of a car company that is not only ignoring all this with production of this car but instead of trying to make a more efficient performance car they bring out a 7litre v8! every couple of years . first a 5.7litre then a 6litre now lets just add even more weight to it and chuck in an even bigger donk. and for all the fuel economy whinges out there we will chuck in a six speed over drive , drive it at 80km/h around lang lang sitting on 1200rpm so that we can claim fuel efficiency figures that you and i in the real world will never achieve! i mean how many v8 owners dont hammer the crap out of there cars from stand still at ever set of lights ! specially when they see a 2litre import in the lane next to them. lol.my 2 cents.

wow. everyone wants to look like an r35 these days. lancers. commodores. yawn.

still, its great to see the motor here, it is a good race motor so this might make the bits easier to get.

Holden's attempt to compete on the same level as the R35 GTR.... definitely doesnt look like a"super car", interior looks cheap - something about the red... the engines nice should be in the coupe 60 body i reckon.

This is exactly what I was thinking...This is 2008, price of crude oil just hit $102 a barrel...unleaded for $2 a litre is not as far away as we may think....With all the problems with the environment and as we are supposed to be trying to cut greenhouse emmisions along comes this great gas guzzler...WTF are they thinking ? Hey why not go the whole hog and fit a 10 litre V10...that will show em !!...When is Holden going to realise that you do not need to have a big capacity engine to make horsepower.? BMW make this power out of a 5 litre V10...Why cant Holden ditch the pushrod and 2 valve engine and go Hitech ..... ?

Um it's not Holden who build these engines, it's GM in the states. The biggest engine Holden has ever made, was the 5L 304. (Though a 5.7 stroker was available for the VS GTS-R)

Edited by RyanVLSL

yes your right.. holden didnt make this engine but who said they cant make theyre own???

They can and have before.. they just think its more economical for them to purchase engines from the states as oppose to R & D they're own new engine.

7lts to make 370kw.. what a waste of space...

ummm champ you did notice I did say Fit this engine - Not build ?...Thanks but I have worked on a few Holden V8s , I am well aware of what they built and didnt....At least with the Yanks there fuel is a lot cheaper than here...More GM usa being an Ass than holden for building such a large engine....Not necessary...

    • So stock ECU does not like anything above 10 psi?  That Nistune one is just for "try" if it will be any different, I know it need to be tune for that. I know but YOU may know about these problem but i/we dont. They few little Skylines here let alone people who know anything about tham so that is why iam asking here  
    • So now we have a radiator with no attachments whatsoever. It lifts up with a particularly tight spot between the drivers side air box mount and the lower radiator outlet, but if you've got this far you will sort that too. This is the lower mounts with the rad out so you can see where the rubber bushes go, it is a straight shot upwards Done! Assembly is the reverse of disassembly, with blood less likely to be shed.
    • Right, onto the second last trick. The Air Con condenser is mounted to the front of the radiator and stays in the car when the radiator is removed. There are 2x 10mm headed self tappers holding the top of the condenser to the radiator, remove those The bottom of the condenser is attached to the radiator with clips. You need to lift the condenser out of those clips and clear (up, then forward). f**ked if  could work out how to do that last bit with the front bumper on. I hope you can, and you share the trick.  Bumper removal probably deserves its own thread one day once I've recovered the will to live, but basically you need to remove the wheels, front inner guard liners (clips and 10mm headed bolts), the self tapper between the guard and the bumper at the rearmost point of the bumper (same as an R32 that bit), any remaining clips at the top/front of the grill, an absolute bastard design with a plate that holds the top of the bumper above the headlight each side (only 1 bolt which is tricky to get to, but the plate catches 2 places on the bumper and must be removed....carefully!) and push clips between the bumper and guard under the headlight. If you've done all that you will be faced with wiring for the fog lights on both sides and in ADM Q50 RS at least, 4 nasty tight plugs on the driver's side for the ADAS stuff. So, the clips at the bottom look like this on drivers side (looking from the front) And on the passenger side (also from the front), you can see this one is already out Clearance on both of these are super tight; the condenser needs to move up but the upper rad support mount prevents that, and the radiator can't move down far because it is (rubber) mounted. Once you achieve the impossible and drop the condenser off those mounts so it does not stop the rad moving, you are good to go
    • OK, next the shroud needs to come off and there are a couple of tricks. Firstly, there is a loom from near the passenger side headlight to the fans, coolant temp sensor etc and there is no plug to undo.  In my case I was OK to leave the shroud on top of the engine so I just undid the passenger side fan plug and about 10 of the clips which gave enough free wire to put it aside. The fan plugs were super tight, the trick I used was a small falt screwdriver to push down on the release tab, then a larger flat screwdriver to lever the plug out of the fan unit....be careful with how much force you apply! If you need to remove the shroud altogether for some reason you will have to deal with all the plugs (tight) and clips (brittle)....good luck. I removed all of the clips and replaced them with cable ties that I will just cut next time. Also, in the Red Sport / 400R at least, the intake heat exchanger reservoir hose is bolted to the shroud in 2 places with 10mm headed bolts; so remove them (the hose stays in the car; no need to undo it at the t fittings down at the radiator lower mount. Once you've dealt with the HX hose and the wiring loom, there are 3x 10mm headed self tappers holding the top of the shroud to the radiator; remove those.   The shroud then lifts out of the bottom mounts where it sits on the radiator, up and onto the engine out of the way. Simples
    • Ok, disregard my “rate them” comment, sorry for my unrealistic input
