CV8 model confusion - but not at Vauxhall!

[nickwaiheke]

Following on from the posts a few weeks ago about 2004 CV8 338 bhp cars being sold as 2005 354 bhp cars. As part of my dispute with the dealer (don't get me wrong I love the car) I asked Vauxhall for a statement on the model/age of mine

No shock on first bit built 2004 but registered 2005 (sideways tank and offside exhaust) but they state it has been upgraded to 2005 specification.

it would be too good to be true to be the power upgrade or would it? (I have asked them)

anyone know?

[jimb0]

The early Monaros have the fuel filler lower down in the rear quarter than the VZ Monaros.

Ask them what they did to upgrade it to 05 spec and how they upped the power?

change the position of the petrol tank
Replace exhaust system
chnage all interior trim
Change the wheels
Change the front bar
add dash top dials
add fly by wire throttle
add bigger maf and other bit sto give more power

etc. etc.....

[Doleboy]

Don't forget to offer half your boot space back to them if that'll close the deal for you

Good luck.

[nickwaiheke]

Vauxhall have agreed that they gave the dealer incorrect information on the BHP/Spec of the car (333 vs 354) and are paying for an upgrade at Monkfish!

and I get to keep the boot size

[ringram]

Excellent resolution! Brakes were larger too.

So maybe you can get the AP's along with your upgraded exhaust and tune.

Let us know what the "upgrade" ends up containing.

[le sarthe]

APs - he will be lucky probably will get a set of LS2 VXR brakes...

Good result though.

[rmmackfc]

Superb! ... think they'll cover a supercharger

[monkeeeey]

This exact same thing happened to me, It was advertised via the NetworkQ website as the (354ps) version. However mine was registered in 06 but was built in 04. So did you write to Vauxhall about this? Was it Vauxhall who looked into it?

[ringram]

Trading standards would be interested if Vauxhall are not.
Im sure Vauxhall will see you right if you were mislead as per above.

[nickwaiheke]

It was advertised by a non vauxhall dealer they contacted GM cust services and checked spec before putting it up for sale. GM cust services told them it was 2005 spec so they advertised it at 354BHP (and I have the advert) once I saw everything you had all put on the forum I contacted GM cust services whilst threatening to sue the dealer. GM at first told me 2005 spec but I asked for specifics based on model number etc. In the end they agreed that they had advised the dealer incorrectly and that they would pay for Monkfish to do the essential pack no brakes or supcharger in the deal!!!

Is there a great deal of difference between 333 and 354.

To me the bigger boot version was a much better package.

Hi AM04ARO,

Probably not a good read for the original poster, but these are the changes I came across on the VY to VZ series:

The VZ is a very miss understood car. Big cosmetic changes, inc nostels, front and rear bumpers plus obviously proper twin exhaust system with all that new space where fuel went. Engine has fly by wire throttle (can be a plus and minus), slightly better soundproofing, uprated stock brakes and mastercylinder, better air intake (smooth MAF pipe as standard) and slightly better shifter (little shorter throw from my test drive of the VY series).

Negatives small boot and more akward for tuning due to throttle system and strange mounting differences (superchargers etc). Also different bits on the suspension as have to drill an extra hole for APs.

I guess Holden used the VZ as a blow out model to test some stuff on the VE series.

Cheers
Steven (VZ driver)

Am slightly tongue in cheek here,

Twin exhaust I agree with - have seen people snarl disapprovingly that mine has only the one
fly by wire throtle is NOT as good - too sensitive when supercharged.
Air Intake - gets replaced anyway.
Shifter - replaced anyway

Comes down to styling vs bigger boot IMO.

And yes CrisisJez - am debating about investigating drivetrain losses and upgrading components or more engine power although will probably decide on getting a decent underseal and getting the paintwork more pristine.

I too have the 05 vz model, but for all the info ive got on the Monaro next to nothing covers this car why? is it any better than the earlier car or is it just cosmetic? If anyboby knows where I can get a good history book on the design of the vz I would be greatfull,or even a workshop manual would be nice.

I don't agree, mine works fine although the ECU did need reprogramming. Other changes include:

"MECHANICAL
Look past -- or through -- the bonnet scoops and your eyes will fall on that familiar 5.7-litre V8 lump of alloy known as the Gen III. In what may be its last time in Monaro, the Gen III produces 260kW of power and a nice, round 500Nm of torque. Peak figures are measured on premium ULP, but Holden says the engine will happily drink regular ULP.

The 10kW increase comes from a new induction and exhaust system and revised camshaft courtesy of Pontiac GTO. Coupled with a slightly easier shifting six-speed manual with shorter ratios (except for fourth), this makes for quicker acceleration and more aggression from standstill.

The four-speed automatic gets the same modifications as in VZ Commodore, which makes it somewhat more responsive, smoother shifting and -- along with the 3.46:1 same final drive ratio as the manual -- marginally quicker also.

Holden's new electronic throttle, which does away with a mechanical link between pedal and power, helps this feeling of immediacy and performance along.

More go, and also more stop. Monaro wears the biggest brakes of any production Holden. Bright red twin-pot calipers decorated with the Monaro moniker grab larger diameter 320mm discs up front, and there's 286mm ventilated discs down back. A new brake booster and master cylinder are said to encourage maximum braking performance up to 50 per cent quicker than before, and reduce stopping distances by up to four per cent.

Aerodynamic work has been carried out on the Monaro's underbody to reduce lift, though drag is up marginally due to the new bonnet nostrils.

Holden has also replaced the power steering pump. The new one is said to keep fluid temperatures down during high stress applications, thus improving feel and durability, and reducing noise.

Mechanical and technical changes have impacted Monaro's bottom line; it's now 50kg heavier than before at 1692kg (manual), and 1698kg (auto). Fuel consumption has also increased, now rated against ADR81/01 at 15.3litres/100km (manual) and 13.7litres/100km (automatic)."

I'm at the same point now, as having found a copy of the advert listing my 04 built CV8 as having 354PS. Having looked about its seems a standard 04 built CV8 pushes out 323PS, so if I were to look at options to correct this would the wortec essential pack meet/exceed this or would it require the sport pack to 100% equal or beat the 354PS figure?

[nickwaiheke]

I had the essential pack today thanks to vauxhall (and of course Monkfish) much sharper
I can forward you the emails I exchanged with Vauxhall clearly if they have agreed onecase then you have a chance with yours was it a vauxhall dealer? my case involved vauxhall confirming to the |(non vauxhall) dealer it was 354bhp which they then admited was wrong if the vauxhall dealer in your case came up with the bhp themselves then they would have to address it problem could be how long ago not up on consumer law
