Gas conversion

[cart]

I have done a search and read on various discussions about gas on the VY,the shop down the road said he could fit and Impco system for $3200.00
this includes a new set of springs(heavier) for the back to compensate for the weight gain,he also states that it wont change the way my car rides with the new springs.


Advantage for me being in a small rural town is that the shop is within stones throw distants and he being local as well u get to catch up with him anytime and as he is the only one here so he can not afford to stuff people about if u get me.

Does that sound like a fair price,car will be in the shop for two days.

Thats all I want to know about the price.

Ty kindly

[rokkz]

The average price around town for the Tartarini and Remano Injected Conversion is between $3700-$3900 this includes a 95lt tank (holds 75lt)
to suit VY V6

Both these appear to be the conversions to get, uncle has the ($3700)(Rowville Vic) Remano in VY calias and hasn't missed a beat, drove it to shepp from melbourne the other day, and couldn't notice the petrol to lpg.

Mate has the tartarini system in his BA ($3800)Doncaster Vic and has performed great however he stalls when the fuel change from petrol to gas while reversing from the driveway. Installer says this is normal.

I'm about to take the plunge , however still deciding what system and what installer, as there appears to be up to $500 difference between some installers , installing the same Tartarini system with the same components to the same spec. Maybe over quoting while busy and if job received a new years bonus!

All have quoted 2 days to complete and no dyno required as program is completed via laptop with the use of existing maps suit to particular models.

cheers

This is not normal AT ALL, especially for an injected system. I'd suggest that your friend take the car back to his installer and demand a retune.

For a VY, I would be paying a little more for an injected system - about $4500 in WA.

I'm considering getting my VY II Berlina V6 converted to LPG.

I was considering an Impco system, because it would integrate with the current dash and ECU.

However after doing a bit of reading i'm confused, what is recommended for a VY V6? Everyone seems to opt for the gas injection setup, why is a gas injection setup superior to the factory Impco system?

[poweredbycng]

Everyone seems to opt for the gas injection setup, why is a gas injection setup superior to the factory Impco system?

Gas injection systems are generally much more refined when compared to traditional "mixer" setups.

Gas injection systems can't backfire because the injectors are mounted adjacent to the petrol injectors, which means that the upper intake manifold is completely free of fuel. An Impco system delivers gas at the throttle body like a carburettor, therefore ignition system and air/fuel mixture problems will lead to potentially damaging backfires.

The gas injection setup also integrates better with modern engines fitted with sequential injection. The gas computer can mimick the petrol injection sequence set by the manufacturer and therefore performance will remain unchanged while running on gas. Fuel changeover is also unnoticeable and all features that are available when the car is running on petrol (e.g. traction control, if fitted) will be available on gas.

As well as all that, a well-tuned gas injection system will return fuel consumption figures very close to petrol consumption figures.

Dave

[commsirac]

all the ^ is good except the last sentence, there is no independent evidence anywhere to confirm that injected lpg systems get fuel consumption close to petrol.

The only evidence atm, says that there is no improvement in this area from mixer systems to svi. The VE comm fact impco svi system still burns ~30% more lpg than when running petrol, according to the official Australian fuel consumption test figures which are done the same way every time.......exactly as what has been tested with all the holden fact impco mixer systems including the VY.

What gives you the authority to think that you're always be right? You have stated all along that you do not own a car fitted with a SVI LPG conversion whereas I do, and have done so for quite a few months now. If *YOU* do not have the experience to back up your claims/statements then please do not comment, as the things you have said in the past have been extremely misleading to other forum members.

Please quote something that i have posted that is wrong or misleading. I dont post rubbish or anything that can't be backed up. True, Ive made quite a few posts that challenge some of the information that you have come up with. You are the one quoting information that has not been backed up by any reliable or independent source. Im backing my information up with the Australian Government fuel testing standards. I achieve exactly the numbers they quote for the Vx for the highway cycle on petrol and lpg(fairly easy to replicate what they do here) and achieve better than their city cycle on both lpg and petrol, so please dont waffle on about how they arent real figures and that in real traffic mixers use much more etc(we are talking about the factory systems) Ive no doubt they were able to perform the same tests on the svi equipped VE comm equally well. If you'd like to tell us how the government testers got it wrong, go ahead.
Feel free to tell everyone how in your vehicle, which defies the laws of conservation of energy, that it is able to strange more energy out of the lpg than is actually available.
Otherwise dont make ridiculous claims that svi injection is going to make a significant reduction in lpg use over mixer systems across the board, people can believe you or not, Im going with the Aus tests and the Holden engineers thanks.

[OFF TOPIC]

Well please explain this. In a previous thread, why did you post figures relating to the payback time of an 'upgrade' (mixer to SVI - vehicle already converted) when people want to find out the payback period difference between a new SVI versus a new mixer installation (petrol to dual fuel)? Your figures are very misleading because it would be almost impossible to recouperate the cost of the 'upgrade' in the life of the vehicle. On the other hand, the difference in time needed to recouperate the cost of a new SVI installation vs. a traditional LPG system is less than two years.

Who in their right mind would want to convert their already converted car from mixer to SVI anyway???

If people want to hear about other peoples' experiences before making a decision, they are highly unlikely to consult any sort of Government test results. I mean, do you seriously believe that EVERY document the Government releases is unbiased and and reliable? I don't think so!

...so please dont waffle on about how they arent real figures and that in real traffic mixers use much more etc(we are talking about the factory systems) Ive no doubt they were able to perform the same tests on the svi equipped VE comm equally well. If you'd like to tell us how the government testers got it wrong, go ahead.

With the wrong tune and/or bad maintenance, anything can/will use more fuel. I could quite easily ask my gas installer to tune my system aggressively so that the thing goes through the same amount of gas as a VE Commodore with the "factory" IMPCO-BRC Sequent system but would we want to? No way, not considering the rediculous increases in gas prices. I'm happy with my 550km+ per 70L of LPG thank you very much.

Feel free to tell everyone how in your vehicle, which defies the laws of conservation of energy, that it is able to strange more energy out of the lpg than is actually available.

Feel free to tell everyone your rediculous claim that a sequential injection gas kit can't be more efficient than a traditional kit. Quite honestly, I am trying to help others make their decision based on my experiences. If all you want to do is ridicule my contributions then maybe you should have a serious think about whether you really belong on these (and other) DISCUSSION forums.

I

This was all very well explained at the time in the relevant thread. Ill make my point again, so no one has to try and look through the smoke screen you are trying to make.
The cost of choosing svi rather than a mixer system is never likely to be recovered in the cost of owning the vehicle, certainly not 2 years. Even allowing a generous 5% improvement of economy in the svi system the average user would need to travel 500,000km to recover the extra outlay for the svi in the fuel savings it would give.
Going lpg is all about saving money? If one outlays an extra $1500-2000 for svi , one is never likely to recover that additional money. There is nothing misleading about this at all, it just plainly lets people see that it is not a rational economic decision to go svi if the fact mixer system is available for use on the model in question.

What is misleading is the idea that because one saves money compared to using petrol that it doesnt matter that it takes an extra two years to recover the cost of svi? It does matter, its not a case of recovering just the cost of the conversion, its the total cost of the lpg and the conversion over the life of the car......the person that goes with the mixer will have an extra $1500-2000 in their pocket from day one.....and for the next 25 years.....and if they invest it.....even more.I really dont know if you can't comprehend this or you are being stubborn, that is why I had to give the artificial scenario of the paying $1500-2000 for an upgrade from a mixer to a svi system.........and seeing how the small savings in the possible reduction of fuel use would take at least 25 years to recover. See:Gas Converted VT

Unfortunately all we got from you and some others was that it would be silly to convert from mixer to svi........it was an exercise to try and help you understand and it was clearly pointed out that it probably wasnt even possible to change from mixer to svi for $2000 anyway! As cheap 6 even pointed out for you it represents exactly the same situation. Once you convert to gas the price of petrol becomes irrelevant, because you are not using it any more(or using significant amounts of it).......it effectively doesnt matter how much you save compared to what the petrol costs........just what your total is running lpg, your total will be $1500-2000 higher if you purchase svi, whether petrol costs $2/L or $5/L. I even went to the trouble of providing a little graphs that will show it all for you:vx on lpg and http://forums.justcommodores.com.au/...-vt-mixer4.jpg


What is misleading and irresponsible is someone encouraging people to choose svi over mixer on economic grounds, it will cost an extra $1500-2000 that they will never get back. The savings in reduced lpg consumption just arent there to make up the difference.

Perhaps here is another way of looking at it. Let's imagine(pretend etc......dont go quoting me), that the you have choice of buying a new car and having to pay separately for a petrol delivery system. A very good carby system for $2000 or efi for $4000. The efi gets 5% better mileage. Would that be worth it on economic grounds, simply no, the amount saved on fuel would take years to make up the $2000 extra outlay. Its exactly the same thing with the choice of svi versus mixer, except it would even take longer to recoup due to lpg being far cheaper than petrol.

You seriously think that Holden deliberately in collaboration with Impco set up their svi system to burn 30% more fuel than it should of, and that the Aus goverment official fuel testing standards have been compromised and are rigged.........that is delusional.

[minux]

What gives you the authority to think that you're always be right?

Hmm correct me if i am wrong but when Consumption tests are done they have to be done by very stringent guidelines with fairly accurate recording. i would think that if these guys can't get the same economy for gas as petrol then no one can.

I am with commsirac on almost everything he has said here.

[djherny]

Hmmm, cant seem to justify the extra expense for the SVI system....

I wouldnt think that a well tuned mixer setup would backfire? I used to have a VL on gas years ago, and it only time it ever backfired was when my moronic ex pumped the acc. pedal whilst starting!

Anyone know of a reputable fitter who can fit a factory Impco in the SE Suburbs of Melb or Gippsland?

[commsirac]

Progas in Huntingdale, Vic. They do the impco fact systems.

I think you are delusional mate...

You are forgetting alot of other factors that come into play, once again commsirac. You consistantly mislead people by giving advice on something you have absolutely no idea about.
Damn you probably havent even seen a SVI system in the flesh.
You have forgotten to add all the money extra that a person with a mixer system is going to have to pay over the years....
I'll list just some of them shall I???
Lets see. The 4 or 5 air boxers they are going to smash to pieces due to backfire THAT ONLY HAPPENS WITH MIXER SYSTEMS>>
The blown mass air flow meter that has been damaged by backfire.
Um the extra 60 or 70 plugs they are going to need due to the fact that they require more frequent replacement with mixer systems. Not to mention other ignition components that are undergoing extra stress when a mixer type system undergoes lean out on fast acceleration (even on the best tuned system. They dont have a accel pump remember but VSI will) and this makes the ignition system spike a huge voltage just to fire the plugs due to less fuel molecules between the plug gap.
The major repair bill owing to the fact the mixer system has burnt engine valves owing to the fact that fuel delivery and metering is inacurate at the best of times causing engine to run hotter than necessary.(even worse if tuned for economy).
Convertor replacement due to stretched or damaged fuel metering diaphrams, which incedently VSI DO NOT RUN.
The numerous injector cleans they will require reqularly for the fact that they will block sooner.
Fuel pump!!! How many of them do I do on mixer systems! They do have a shorter life on mixer systems thats a fact.
I could keep going.
How many thousands of extra in repairs do you think that adds up to commsirac???
Obviously you are gonna argue this also..
I will be amazed to see how you argue the point on this. The facts are mixer type systems do stress engines far more than VSI systems, all down to poor fuel delivery. Mixer systems are just too slow. We are in 2008 now matey not 1984 like your commo. Engines now require the same fuel delivery as petrol to keep them in good shape. A mixer system just can't deliver that in this day and age. Engine components are far lighter and less forgiving to gas if not delivered accurately .
I don't understand why the hell you are so against VSI. The difference is like chalk and cheese in drivability and reliability and most people could not give a poop that they have to pay extra, just the simple fact that they know their vehicle will run the same on gas as on petrol AND NOT BACKFIRE, is more than enough for almost anyone I know. **** tens of thousands of happy customers worldwide cannot be wrong, but one simple moron in australia thinks he knows more than all of them, yet he has never been close to owning a VSI powered vehicle cause he is too simple or broke to afford one so he has to bag anyone who has. Jeez they must all be idiots according to you commsirac. They have thrown away thousand of dollars.
Its like saying the Statesman owner is an idiot and has thrown away money cause he could of got a bog stock Commodore to do the same job.. Its just lunacy what you are saying mate.
I have shown VSI owners your numerous posts and one guy was on the floor in tears about how funny you are. ONCE again YOU are the one that is delusional mate.
I challenge you to buy a vehicle and get VSI fitted and then argue me the economy point. Time and time again you have people on this forum and other forums state to you how they regularly achieve better fuel economy than your 30%, but you seem to not listen, Why is that???
You really need to get a life mate.
You really need to stop bringing people down and ripping them to shreds just cause you have issues with yourself.

[commsirac]

Goodness, should I take out a bank loan for all the anticipated repairs on the mixer systems I have........that have been barely touched over 15 years of running and run spark plugs for 60000km no probs? Something isnt ringing true.

Yes, Im sure we all understand your point, possibly the fuel injected cars with airboxes have extra liabilities......something I havent had to deal with on the 2000Vx im running yet.

Have I got anything against svi's, no, would love one fitted.....they are superior......am I willing to pay out $2000 more for the privledge.......no, with only hearsay economical benefits in reduced consumption and repairs, no.
Should anyone else, that's up to them, but so far the challenge's Ive issued to people such as yourself an poweredbycng have not been addressed and only replied with personal attacks as you have ^.

One major sticking point is:" why do the only independently controlled fuel tests available on svi systems show that the VE svi commodore shows no major improvement in efficiency over previous fact mixer systems".

This was your last reply to this:
don't need to justify anything to you about any claims Holden make with their systems mate

Well, here you are telling the world what an idiot I am, but someone in the LPG game has no response to this straight forward and highly relevant question ?

[minux]

blownba, whilst I appreciate you are trying to cover all angles for users here you need to stop referring to what you install. Tell people why you like something end of story. We really do not appreciate people coming on here and silently selling products they use/sell/install.

If you would like to do that email Darren and become a sponsor.

There is also no need to get personal towards members for having an opinion on what they believe to be best. Respond in fact but keep the personal crap out of it please.

Guys, you have both have good experience to help people out here, let's keep it that way eh?

[blownba]

UM... At what point have I refered to what I install here???
I am not silently selling anything here. I am happy to tell people what products I use and believe in because I consistantly end up with VERY happy customers using it (just ask the numerous forum members that I have helped) and I think that its something I like to share, BUT ONLY if someone has asked for advice.. I do not start threads saying that people should come to me to buy my superior products. In fact comming on here costs me money cause more often than not I waste alot of work time on the phone HELPING people out and taking a look at their cars FOR FREE most of the time.
So there really is no need to have a go at me for trying to 'silently' selling my products on here when that is the last thing I need to do believe me. I have more work than I can possibly handle.
I am only about trying to help people out and try to give them some first hand advice on subjects that I may have some knowledge about.
When people consistantly overide my help or comments with their own and they do not have any first hand experience, it really gets my goat, and others as you can plainly see.
I was thinking about becoming a sponser actually, but I don't think that I would be appreciated by the sounds of it, cause my tactics are considered underhanded judging by what you and whoever 'we' are saying.
The only reason I would say what I install is simply because of what products I use I obviously like and would like to share that to people who have asked for advice.
At no stage have I started a thread saying come to Anthony's I sell the best gas blah blah blah. Correct me If I am wrong.
The main reason why I have responded in this way and powered by cng would be in the same boat also, is that no matter what advice we give people we have the hero, commisirac, constanly trying to cut us down and undermine what advice we have to give. That is why it has come to the point where I attack back.
I, and many others, have consistantly stated our consumption figures to you commisirac yet you make us out to be monkeys and NEVER believe any of the claims unless we have the government testing lab hanging around in the boot of our car to record our figures.
Why is it you cannot take our word for it???
Have you been running your VX for 15 years have you.
We are primarily talking about V6 commodore engine here are we not???
They are a whole different kettle of fish from your old and primative commodore.
Waste spark ignition on these commodores WILL CAUSE PROBLEMS WITH MIXER TYPE LPG SYSTEMS.
Its a fact.
And half the guys on here are not gonna pussy foot around on acceleration like yourself so you can see that you are comparing apples with oranges again commsirac.

No denying that, you probably know as much more about lpg systems as anyone Ive heard, and sound like you really are one of the best installers around.

That is why it has come to the point where I attack back.

Yes, we have seen that you dont react well when someone actually questions something you say, perhaps dont post if you dont want to be challenged. I gather you are referring to me, what else do you have a problem with other than myself questioning the economic benefits of svi systems? Please refer to any post where I have made a personal attack on yourself.

While you may be expert in how they work, we havent seen one cost analysis benefit from yourself or anyone in the lpg industry on how they stack up......other than they are good mate, ask my customers......

Ive dared to do some basics costs comparisons and expressed my concerns to others that it doesnt appear to be a wise choice from an economic standpoint, and we cant even get a simple answer to this question:

why do the only independently controlled fuel tests available on svi systems show that the VE svi commodore shows no major improvement in efficiency over previous fact mixer systems"........top secret?

Perhaps you'll let us all in on the secret as to why the petrol pump in an svi vehicle will last longer than a mixer one?Does one run the pump while using lpg and the other doesnt? Dont the petrol pumps die prematurely in efi cars when people run them out of petrol and continue to run the car on lpg, causing the pump to overheat etc? (I dont know, just asking)

as far as im aware, svi systems run the engine on petrol until the water temp reaches a pre-set temperature, where-as mixers can be started and run on gas for weeks without being switched to petrol, so svi will use the petrol pumps more therefore its lubricating the seals in the pump when they can seize on mixers set-up if not run on petrol for long periods of time, i guess

i don't want to cause a fight but id prefer to loose the 1500 hundred for svi (also because that's the only compatible system for my engine) i see it like, performance and reliability is (can be) superior to mixer, and fuel savings is a bonus

[holdensupporter2005]

I am considering the SVI Gas system for my VY as the Impco Gas cannot be fitted to Manual VY's, Due to backfiring and the fact that holden hasn't and won't produce the software required for gas on a manual system.

[Flat_White]

Hey,

first of all this is such a "heated thread" with all this debate about VSI vs mixer.

My question has 3 parts,

1. Roughly how much is it for the IMPCO system to be put on a VYII,

2. Does it have full dash integration?

3. Anyone know any fitters which do the IMPCO system in WA?

cheers people,

[Tilvywgn]

Gidday
had my VY series 1 Berlina wagon fitted with a SPRINT gas system last week, mixer setup, no dash integration and Im more than happy with it: uses 12-13(max) l gas/100 km, tank in the spare wheel ditch, and gas gauge on the right hand side just underneath the dashboard. cost 2900. It uses petrol to start and immediately, after 1 second, switches to gas, works flawlessly

[Tilvywgn]

Vikky. Went to Mt Gambier on the long weekend from Echuca way, and used about 10.5 l gas/100ks highway cruising. I found Caltex pumps fill the tank right up, I was able to squeeze 53 l in the donut tank (which is 60l in size but according to the installer you can only fill it with 52l - so it was full to the brim). Filled up at a bp and it cut out earlier... might be just different stations tho.. anyways, if I can replicate 10.5 l gas /100 ks Id be more than happy. Another thing the installer mentioned was that after a while on gas, you get a bit more mileage out of it.
