Gday all
Just thought I'd let you all know that my 99 TD Jackaroo is now on Gas. Took 1 day, $4014 (and hopefully getting $2000 rebate soon!).
I am a little disappointed on how low the tank hangs underneath. They said it wouldn't affect clearance. Crap. It's certainly not the lowest point (apart from the diff cases the transfer case bash plate is), but it's fairly long and large underneath, but for the purposes I use my vehicle for, mainly touring, beachwork and towing the CT, shouldnt' be a problem (very little
rock work/deep mud etc).
As for performance, WOW. Feels a lot more thant 20% power. The performance claims are certainly true. Literally throws me back in my
seat. The performance of the Jack was pretty good compared to other high-tech diesels prior, and more than adequate for the off road stuff I do, but now it is a cut above. Revs up to 4000 rpm effortlessly, picks up the pace at 1500rms (instead of 2000 plus), turbo lag while not real bad before, is even less noticable. I
'm certainly impressed.
Now waiting to see the economy figures. And I guess the harm the increased power/torque can do in the long term is still out there, but they claim cleaner fuel, lower exhaust temps, which won't cause harm.
Had it done at Dieselgas Austm Churchill Rd, KILBURN. No affilliation unless having work done there is affilliation!! if you know what I mean.
I got it mainly for performance an extra range - should be worth at least an extra 200 kms under normal driving - this gives me a touring range of over 1100 kms with the 133L diesel tank plus the 27L gas.
So I can't comment on the economy yet, but I can thoroughly recommend the LPG for Jack diesels for the performance side of things. It would be a killer on 3.0 TD Prados I reckon.

Hi djack
I thought you got it done for a good price because the government announced the rebate 4 weeks after i got my 5 litre berlina on gas.Gas injection was about that price then..
I thought with the rebate it would have gone through the roof like the first
home owners grant,within 6 months the improved house prices swallowed that up..
Good luck and am sure you'll be happy with it especially at the pump ! ~(8--)

It's funny - I priced a diesel gas installation back in 2002 when I was involved in a little offroad comp work and the company I got the quote from were selling them for $2200 installed with a 30l tank. I baulked at the idea because of the cost but now I look at it now, what a bargain. There was hardly any demand back then either.
The product was not as refined in quailty as they are now either.

David

Some years ago i had a lpg/petrol car so my experience may now be a bit out of date. I found that the tuning could make a huge difference to power and fuel consumption. If you tuned for power it was heaps better the petrol but was very thirsty. If it was tuned for economy then the power was
well below petrol but cheaper to run. My experience was to get someone who was very eperienced at tuning and make sure they know what you want, power / economy or somewhere in the middle.

Diesel/Gas is a different animal to Petrol/Gas. It is not an either option, the gas is more an additive to the air intake. The motor remains diesel and does not require any alteration to its operation. Gas is about 0 - 30% of the fuel going to the motor. You get more power for less pressure on the accelerator. If you turn gas off or run out the motor runs as normal diesel, you just loose the benefits of the gas.
I have had
mine for over 12 mths now (TD4.2 patrol) and more than happy.
What you say about tuning is still relevent in that you cannot as yet go to any tuner. The gas is tuned on a dyno with a computer plugged in to gas system. You are stuck at the moment with going to the installer.

Thanks Kiwi, but Diesel LPG systems are a little different - they only inject gas into the air intake to assist the diesel to combust (to almost 100%) rather than run on gas. The diesel injection/tuning stays exactly the same, the gas is regulated to get a correct ratio (aiming at 100% diesel combustion as this is the most effecient ratio) and is injected only under throttle and according to throttle pressure. thefore no tuning is required unless you wanted to muck around with the original settings of the diesel. The car keeps running normally when the gas runs out or you turn it off.

G'day PK,
Good to see you've gotten on board with the diesel - lpg technology mate. Hopefully you'll save yourself good money in fuel. Just one thing though, looking at these dyno figures it's actually a fair bit less than i expected you to have. Not sure who's system you've gone with but I know that with our system we normally get around 25 - 40% increase at the wheels but you're only showing just under 15%. Might be worth getting it rechecked, not trying to shoot you down mate. It's just that the better the burn of the diesel fuel = the better performance = less throttle = money in your pocket.

GDay Dallas
Am in Vic. Have had the system for over 12 mths, one of the 1st done. Originally had 84kw v 103kw, but seem to have dropped 10% somewhere. Not sure if it is the diesel tuning or gas tuning or both. They did not appear to have adjusted anything under bonnet on dyno and just gave it a couple of runs. Have had trouble with system reducing gas usage and it has been back 5 times in last 12 months. The problem is the technology is new, and the installers are the only ones you can go to. Nobody else does gas to my knowledge.

G'day PK,
Thanks for not biting my head off mate, i honestly wasn't trying to bag it or anything.
I know what you mean when you say that nobody else can look after it for you. Makes things difficult i know but to be honest... we are exactly the same with our own system at the moment. We've developed this system completely in-house & we are absolutely paranoid about letting other people adjust it or even tinker in case they stuff something up. It's a simple concept on how the whole process actually works but you really do need to know what you're doing with it or you'll simply turn it into a hand grenade & there goes your reputation & everything you've worked your butt off for, just like that.
Also mate, good to see that you're keeping an open mind as to what may be responsible for the decline. Of course the tuning of the diesel is pretty crucial in the whole game too, not just the gas. Most people just start jumping up & down about the gas because that's what was touched last.
Anyway, once again mate, good to see you've gotten involved in the diesel gas world. Hardly anybody knows it can be done so they're not banging down our doors to book'm in. Hopefully we'll reach critical mass where it's simply the norm.
All the best PK
Regards
Dallas Green

Hi D-Jack
Have just had the system installed on my n/a GQ 4.2 nissan. Only done 400kms so dont have any economy info as yet. However appears the system is not as good for power on a non turbo vehicle. Also, has been blowing heaps of black smoke since fitment. Am going on a trip out west next two weeks so should have some feed back when i return and will have the system retuned then.
Regards
