Gas injection - LPG Conversions?

[VYSV8]

Has anyone converted their LS1 to LPG (dual fuel)?

What (if any) systems work?

There's no way I'd convert my car to LPG using a crappy old gas mixer, but I'm wondering if there's a better way (some sort of injection system).

Does anyone know of any quality workshops doing good LPG conversions?

Thanks All!

I too have the same opinion as you I have contacts in the industry and I have been waiting three years now for an injection system and while they are available in limited form I am not convinced they are there yet for large capacity engines I am advised there will be an approved gas injection kit for Gen111 available early next year.

There's a crowd retro-fitting LPG Sequential Vapour Injection systems onto customer's cars. You're right. They seem to be limited to 200 kw's max. Here's their web site:
http://www.parnell.com.au/index.php?option=content&task=view&id=3&Itemid=26

And here's an extract from their web site:

In collaboration with our overseas suppliers, Parnell LP Gas Systems are thrilled to introduce the next generation in LPG equipment. Parnell S.V.I. is a truly unique Sequential Vapor System that will deliver improved power, performance and emission output when compared to conventional LPG systems.

Parnell S.V.I. is the most advanced system on the market today. The equipment is easy to install and does not tamper or interfere with the on board diagnostic equipment fitted to todays vehicles. The set-up of the system is trouble-free thanks to a simple and intuitive software program, which drives the operator step by step on tuning and service.

Parnell S.V.I. incorporates components that are revolutionary in design, the days of large and cumbersome products are long gone. The slick design and presentation of Parnell S.V.I. means that the integrity of the vehicle and its performance are not compromised in any way. Backfires and consequential damage to air induction systems are eliminated due to design and technology utilized in Parnell S.V.I. - the system will deliver safer and more cost effective motoring to all.

I have no idea how well this system works. Has anybody tried it? From memory, it's not cheap - $4000 or thereabouts.

The other issue is, can any of the LS1 Doctors rejig the computer to take advantage of LPG's 100 RON rating?

pah,
I managed to get hold of their Technical Director, John Parnell, and he assured me that a system will be available at the end of this year. The cost will be around $3800 and you will lose about 5% of peak performance on your LS1.

The Parnell system will handle about 220rwkw but is not available for 2004/2005 model commodores due to some compliance issues.

It is available for the earlier models and a few have been fitted in Melbourne.
( March is about the first available date for fitting in Melbourne. )

In Sydney The Gas Man is the agent but it appears they have not fitted any
system to date.

LPG has an unusual ignition curve, they do respond well to ignition remapping
and it would be easy to remap with HP Tuners, Flashscan or RTLS1.

There is a vapour injection system currently being used on V6 Rodeo and believe it or not when a high LPG demand is required it switches to petrol because the equipment is designed in Europe for small capacity engines and it can not keep up with demand on the V6. I believe the upcoming kit for the GEN111 has the same operation hence my original comment.

A neighbour of one of my freinds has a supercharged Toyota 4X4 running on LPG.
He was told by his tuner that that the available LPG injectors are only good for 30kW each.
Maybe the obvious solution is 2 injectors per cylinder?
Still, 30 x 16 only equals 480kW at the crank - fairly ordinary for kW junkies like us yes?

I saw something on the New Inventors on ABC a few months ago. The guy had designed/sourced larger gas injectors that deliver the correct amount of LPG using the cars standard ECU (no reprogramming/edit required). Just an injector change and gas fuel tank etc. I dont know how successfull this was but it seemed like it would work well (don't know about its use in high performance engines though). It's only problem I could see was that you had to run LPG always, it was not a switchable system.

I have had the pleasure of meeting Bill Campbell from Gas Injection. The GTI Stealth system is awesome!! i highly recommend that EVERYONE reads the information on his site, especially those LPG critics...
I have seen the result of his XR6 running Gas Injection, His club car running gas injection, and his sons go kart running gas injection.

Biggest killer, the aussie govt has set him back a fair bit, mainly with funding. The Aussie government gave some tool a grant for $500,000.00 to find out why when ya favourite thongs get washed out to see only the left one comes back to land.. Yet they cant give a fair dinkum Aussie CHAMPION who has dedicated his life to LPG and researching it so that People like us can get the full benefits of it... Not to mention the enviromental benefits...
Look here for what he did to a VY Clubbie R8 just by adding the LPG Injection system http://www.gas-injection.com.au/media-releases-gas-injection-technologies.html


Please show your support, sign up to his mailing list, and maybe we can get this awesome product available to the community alot sooner.

One of our sponsors on here APS in Frankston can do gas injection on Gen3's

Has anyone had the APS Gas Injection system put on there Gen 3?? If so anyone got any before and after figures they would like to share?

From what i have seen in the last few hours, the Gas-Injection GTI Stealth System is the only one showing a HP/kW increase....

there's a mob in stkilda rd melb that are going to be releasing an even better system for the v8's and turbo's next year. It's going to be LPG Liquid injection.... it will offer 15-20% power gain and also be able to chill the air slightly, hence the forced induction benefits. I think the injectors replace the petrol injectors and can inject either petrol or liquid gas.

http://www.lpgli.com.au/

I've got all there testing and comparisons in a rather long word document if anyone wants to look at it.. just pm me your email address.

re: the vapour injection - Also LPGAS-1 Install these systems in melb out at Lillydale and i think they have a couple of employees (one in a SS UTE and one in a XR8 BA) who have their cars on gas.

I think they are booked out til march now though.

Would that be Sam Xuereb from Traralgon area?

ANYONE FROM wa DONE A CONVERSION YET?? LIQUID i MEAN

Australian LPG Warehouse in Frankston are distributing the ICOM JTG system.

Have a look at this post from APS in Frankston:

If LPGLi release something in the next two years I will be utterly SHOCKED!!!!
I have been listening to these guys say this for the last 6 years or so at least. I saw a prototype of theirs at least 14 years ago while I was an apprentice. All they have managed to do as far as I can tell is ask for more money and not return on their promises.
I don't wan't to flame them too hard as their system looks like a great thing, when its finally ready for sale.
I have been authorised to fit the new Icom JTG system through Aus LPG warehouse, and I know this stuff is awesome. It is on 30,000+ cars in Europe, it is OEM in Japan for Subaru and in America Roush have a F150 for sale with the JTG liquid injection system that is marketed as a perfomance vehicle purely due to the increased performance that LPG liquid injection brings. Now if Roush and Subaru have chosen it for their vehicles, surely that is saying something???
GM america also have a 8L running it for sale and in the UK its massive also.
The stuff has gotten so good that it is now being marketed as a performance enhancing product that is better for the enviroment, over a money saver. The Europeans fit it to their high end Porsche's and BMW's for a gain in HP and Torque. There are some filthy awesome cars running it in Italy too.
In the U.K. I saw a hillclimb car that rips its petrol counterparts to pieces running JTG.
I am extremely gratefull to be considered to be one of Aus LPG warehouses authorised fitting workshops.
Hilbert and Mick and Ben and all the guys there are freakin smart mothers and have set the benchmark for LPG in Australia. They have done a massive amount of work to get this system into Australia and then to gain approval from all the relevent bodies is a awesome feat, to say the least.
All the stuff we have used from Aus LPG warehouse has gained us perfect customer satisfaction, that was with the older vapour injection, now with this system we will be enjoying excellent results too.
Well done Aus LPG warehouse. if it wasn't for you guy we would not have a liquid injection system for many years to come.
