    Pajero LWB Wagon, Power/economy what's that ???
    Same old theme revisited ie: VN vs VP - V6
    After a little research (Father's friend has worked for a Holden Dealership for 30 years as Manager) I was provided with the following Holden official claimed specs for the VN & VP sixes.

    Holden Commodore VN SI
    Year of Introduction: 1988
    Engine: 3.8 litre EFI V6 ; 5.0 V8 EFI
    Power: 125kW (V6) & 165kW (V8)
    Transmission: 5 speed manual ; 4 speed Turbohydramatic ; 6 speed ZF manual (Group A)
    Performance: 0 - 100 km/h 8.1 seconds (V6 Auto) 7.2 seconds (V8 Auto); Standing 400 metres 15.7 seconds (V6 Auto) 15.1 seconds (V8 Auto)
    Production: 215,180
    Price: $20,014

    Holden Commodore VP SI
    Year of Introduction: 1991
    Engine: 3.8 litre EFI V6 ; 5.0 V8 EFI
    Power: 127kW (V6) & 165kW (V8)
    Transmission: 5 speed manual & 4 speed Turbohydramatic 700
    Performance: 0 - 100 km/h 8.0 seconds (V6 Auto) 7.2 seconds (V8 Auto); Standing 400 metres 15.5 seconds (V6 Auto) 15.1 seconds (V8 Auto)
    Production: 92,860

    This appears to clear up the the debate.
    But I was told unofficially the performance claims were exaggerated for the VP. The modest 2kW power increase, the increased weight along with the Cam variation, gearbox recalibration (Autos) and computer enhancements to make the VP (and VN series IIs) more tractable in normal driving (read as reduced harshness in the takeoffs) robbed it of some of the lowdown performance of the series I VNs. As speeds rose the cars were close to identical in acceleration but the VN would have a sizeable lead in initial takeoff that the VP could not make up.
    At the time the 4.0litre Falcon was ready for release with a lot more power than the Commodore (but less performance) and Holden did not want their updated Commodore, on paper at least, showing less performance than the earlier model.
    This is what I was told so please don't shoot the messenger. There are probably quite a few "Official" Holden connected people who think or know this info to not be correct. As for myself having owned VNs SI & SII and 2 x VPs, from my experience this does sounds plausible as my SI is easily the quickest V6 I have owned.
    If you look at Modern Motor and Wheels issues covering VNs & VPs the Auto VN SIs consistently ran 8.20 seconds 0-100Km/h and the VN S IIs & VPs 8.96 - 9.3 seconds.

    VN/VP with 300 000 + on the clock will not do better than 9 seconds to 100km/h I predict.

    Yes they were quick from the factory and that was 13-15 years ago but most are aging rust buckets now (no offence) unles their owners are spending money on servicing and restoring the car.

    Mine has 275,000 and still runs 8 flat or better most of the time, stock engine, exhaust, it has never never ever ran anywhere near as slow as 9 seconds not even with heaps of wheelspin on launch in the rain.

    Oh yeah I forgot something :). The lesson is think twice if you reckon you can get to 100 quicker in your VS than a Series one VN, you might get a suprise :D

    Gas

    I forgot to add I had my Lexcen timed running on gas (dual fuel setup)
    0 - 100km/h = First try, floored it, big backfire and then 10.25 seconds.
    Taped together the blown apart airbox and tried again with a gentler start.
    9.45 seconds was the best I could get.
    Switched it to petrol and laid one run 8.02 seconds. So by the Kilometre/performance formula with the huge 240 000+ KMs and the rust, it must have run 7.0 flat when new. I don't think so.

    I ran a 8.09 in my VN Lexcen on the way home after replying up there at my parents house :) bit slow for my car but pretty good for 270,000ks : ), Toa said his parents VN runs the same times now with hundreds of thousands of ks on it as it did when it was new, My friend has a fairly strong VP with extractors and exhaust, really swarve cai and filter and his runs low 9's on gas, but it's much faster on petrol. You have to remember the Lexcen is carrying at least 40kgs more weight than a Commodore Executive so the base model Commodore should be a bit quicker

    My Lexcen is dead stock (I now Know about the headers on SIs thanks).
    My Cat rattles very badly but does not effect performance unless it gets, as it does occasionally , a rumble in the exhaust like a mild backfire. It then is very slow off the mark until it clears itself. I am going to fit new plugs, leads and Cat when I get the money. It appears I am getting unburnt fuel in the exhaust so I may have an occasional misfire. I hope this fixes it as I get very strange looks from other drivers when my car growls at them.

    hahaha, that would get you some 'different' looks from people waiting to cross the road when you drive past while its happening lol.
    but yeah the VNs go pretty hard, and correct me if im wrong but are the lightest commodore? i heard that somewhere but im not sure about it because the VL it smaller.

    Id read those with a grain of salt, VS ecotec produces 147 kw not 145.

    Weight

    I can't remember the exact weights but I was surprised to hear, more than once, that the VN was lighter than the VL. I have a magazine relating solely to the VN development so I'll dig it out and see if the comparison is shown.
    Unless someone out there knows for sure and posts it before I do.

    I think without the V6 installed the VN is about the same weight as a VL without it's motor but I reckon the VN is heavy all together :)?. The earlier Commodores were lighter and it makes sense the VK was the lightest since it had less steel on it, but I bet some of those VBs-VHs are pretty light now days : ) with super light weight racing doors and front chassis rails : )

    Anyway, the quickest V6 now is the sporty version of the VZ : ) so the VN series one lost it's crown allready

    Dreaming

    Yes the VN has had it's glory taken. Oh well it lasted a long while.
    If I had the money I'd love to buy the new V6 sporty. Unfortunately I don't but I can squint at my car and pretend. Fortunately I love my VN and it was cheap. $600 not running and no brakes but licensed. $15.00 for a brake booster hose and insert and a piece of vacuum hose from the shed and it hasn't given me any trouble other than a backfire when using BP Gas and the rattly CAT. Touch wood.

    If I had 40 grand to spare I wouldn't touch a VZ V6 with a 50 foot pole, I'd be down talking to the ever popular Ford salesman : ) asking for a deal on a Turbo XR6. It's going to go down in history as the craziest machine Ford ever made. Just wait 5 years or so till they get cheaper secondhand and the majority of them will be running 12 seconds or better on the 1/4 mile, it will be a revelation, a second comming of the insanely fast Australian muscle car : ). I've allways loved Holdens but you've got to give it to Ford on the BA, looks great, goes great, they won that round :thumbsup:

    If only it weighed 1300kgs :) now that would be something

    So True

    I have never given the Fords much thought until the BA was released. I think it looks better than any Commodore.
    I think I would buy one over a Commodore. There are a lot of different reports going around about the Turbo, good and bad, but nobody can argue with the stats.
    I think the bad reports are written by disgruntled Commodore fans as they tend to list a lot of petty excuses for why it's not as good as the Holden.

    a well run in engine (without any excessive wear) will be more powerful and smoother than brand new.

    Wouldn't care how fast a XR6 Ford was, I would rather push my Holden then buy a Ford.

    Mate seriously Ford and Holden, EXACTLY the same QUALITY and exactly the same MARKET appeal. Why are you so against Fords? If you owned a BMW or Merc and bagged a Ford/Holden then fair enough because Ford and Holden dont compare to the Euros cos quiet frankly in comparison Ford and Holden make crap. If I could afford a 50 K car do you really think Id be driving a 7 K commodore?
    One thing Fords and Holdens have is speed for cheap price...
