all Super 6's have 3.08 gearing and power mode will effect what gear you are in at a certain speed/load therefor your revs can be different

and the shiftkit also helps a little with the firm shifting

Sorry, wasn't clear. Power mode doesn't change the RPM in a gear for a specific speed.

i.e. if it does 80kph in 3rd at 3000rpm, the rpm won't change whether you're in power or economy mode.

[edit]
Actually, by the looks of it all automatic VN - VY, V8's and V6's have the 3.08 gearing.

all auto's have 3.08, manuals are 3.45, clubby R8 are 3.73 and the GTS is 3.91 (clubby and GTS only apply to VTII onwards)

Remember that something as simple as different tyre diameter will alter your cars final drive ratio.

I understand what you mean about keeping RPM constant in the same gear, but from what I understand from the original post, its not kicking into 4th/overdrive...

I would assume the diff ratio is the same, but since the box is entirely electronic, i believe that they have a different shift pattern, which only puts it into 4th gear closer to 90km/hr where as N/A varients will happily go into 4th around 75km/hr

Yeah, agreed. Yeah, that's true, sikvw. Doh, I meant non HSV autos only, damn, I keep missing the last detail. I'll fix that.

1,800RPM cruising is pretty much what the gearbox is programmed to do.
It will try to cruise @ 1,800RPM no matter what speed you do. Cruise along at 60km/h you'll notice it doesn't engage 4th gear at all, but hangs around the 1,800RPM mark.
Try cruising at 75km/h over a slightly undulating road, the gearbox will pop in and out of 4th as it gets confussed about whats going on and tries to maintain 1,800RPM . Annoyed the Hell out of me when I first got the Statesman.

Boost gauges arent wired in, they run off a vacuum tube. Super SS's idea is a goodun. I've contemplated fitting one, but dont want to spoil the Stato's interior looks .

Water injection squirts a fine mist of water (like fog) into the intake. The idea being it cools the intake charge. Cool air = denser air, which = more power. Also when you start upping boost the compression of the air causes it to heat, which in turn harms power or causes detonation (which harms engines). Water injection cools it down etc etc.

Stock Boost is 6PSI.

And finally.. I dunno about everyone elses ride, but if you muscle the Statesman off the line she's more interested in turning the rear Toyo's into clouds of smoke, so you can't be too excitable off the line.

Is there a reservior for the water injection that you have to keep an eye on?

yep...just fill it up every time you fill up with fuel and you'll be fine

Most systems patch into the windscreen washer bottle. Which is cool in something like a Laser TX3 Turbo Ghia 'cos they've got a "Low Washer Fluid" level light in them .

As far as I know the only water injection systems are aftermarket ones, no company fits them as standard.
Trivia Time: Holden considered upping the boost on the VL Turbo's & adding factory water injection but canned the idea as they figure (quite rightly) most lazy bums wouldn't bother filling the resevoir and the engine would ping to death.

Oh, and water injection is not the same as intercooler spray.

Im getting H20 injection on mine when I get it retuned after the cam install (in a couple of weeks). Just dont go to stupid with the water or you will remove the teflon coating on the rotors (also no methonol mixed in to the water).

Water injection is used to cool the intake air and is found on many prop powered military planes (not jet powered, obviously). Works in a similar fashion to an intercooler, but it's impossible to intercool a supercharger that sits in the valley of a V8 and blows directly into the intake manifold.
As a result, it does prevent detonation as a side bonus.

Not impossible

The US boys have a water intercooler than sits inbetween the inlet and the blower for the super 6. Of course it lifts it a little, but like those guys care about a little bonnet denting...

Its not from the US, read this months issue of streetmachine.

Sorry to hijack the thread

My mate has a '98 VT, looks the same as in the vids that Supper SS posted, and i was just wondering would it be possible to put the same supercharger system onto his engine??

Is is possible to turn that VT into a 'normal' supercharged V6 VT?? And also what i read on the website (http://www.v6supercharged.com.au) was that with superchared V6 they had some sort of air hose which was used when just cruising, thus not using my fuel, but when stomping on the pedal, it would use the supercharger...

Would something like this be possible as well?

Sorry if this is a noob question, but i only just started to get into this kinda stuff..ohh and one other thing...is a nice big turbo possible in this car as well?

If you want to bolt a factory Holden supercharger onto a normal ecotec engine, no it wont work. There are a lot of differences between the supercharged motor and the N/A one. If you want something that looks factory, get hold of one out of a wreck and put that in, otherwise there are a heap of aftermarket setups/kits available.

CAPA are probably the best known for S/C setups on commodores, but STA also do some good work.

Turbo's are possible on any car, it just depends on the amount of work (and money) you're willing to do. A twin turbo setup using something like twin GT25's would be perfect for the 3.8L 6's

To put the m90 on na 6 you will need the super 6 inlet manifold, heads, fuel rails, injectors, fuel pump and blower of course as well as computer retuned by Kalmaker.

Also the cam is slightly different and the pistons are different (super 6 are coated and 8.5:1 compression) but stock ecotec will work but dont run high boost levels.

Anyways you cam buy my factory cam in a month

Thanks for those replies..

I thought it would be alot of work to fit make it into a factory supercharged V6, but damn, didnt think it'd be that much...

What are the rough price estimates that you guys rekon for making it like a stock supercharged V6, and putting in twin twin GT25's as white lie said??

2 options really:

1) Buy a super 6 motor and a few bits from a wrecker, do an engine swap, then a turbo conversion

2) Rip the stock engine apart, put new bits in (pistons, rods if going for heaps of power, cams, etc) upgrade fuel system and then get turbo conversion.

Option 1 would be about 5g + cost of super 6 motor
Option 2 would prolly costover 10g, exact amount depends how much power you aim for.

In the end, prolly cheaper to just buy a VS calais with the super 6, and go from there

goto http://www.commsport.com.au
They make turbo kits for all holden v6's

HypoV6 from Summernats has a turbo on his 6 and its based on the commsport kit (although has a few extra goodies)

i hope you people who tap into the washer fluid reserviour make sure your mechanics dont fill the bottle with detergent when you get a service... :/

HypoV6 has since changed his setup from the Commsport kit and has made a lot more power...the car is also up for sale now too

galapogos01: Im going to run a seperate bottle for h20 injection, I got the perfect spot to mount it from a pic on another site, right under the power steering fluid bottle

[white lie]: I heard that he has already sold it

I think it got sold and the new owner is now selling it...anyway, its up for sale on the S/C forums

How about 2 turbos?
one running off each bank feeding into one at the intake, sounds good to me, that would be nice on a 6, something like to t4's,

That would be a complete and utter waste of time and money as the factory superchargers are pathetic at best may I suggest that you go here "www.capa.com.au" and have a look they have many different kits availible that are far superior to the factory supercharger.

dont you mean the rear toyo!

can't believe holden released the super6's with a one legger!

Marlin: the factory superchargers, while not the best can still be bloody quick.

For example mine runs consistant 13's

the thing with the factory blown 6s .. although the M90 aint exactly the best blower in the world .. is that the engine has been setup to handle a blower .. as opposed to buying an L31 and THEN blowing it .. i'm not quite sure how much boost a factory L31 can handle.

SuperVT: Don't you mean L36?

haha yeah .. same **** diff smell .
