    Fitting add-on LPG to Turbo Diesels

    Hi All

    Anyone have any thoughts and experience with these new systems.

    Apparently they qualify for the LPG Vehicle scheme $2000 grant from the feds as they cut fuel consumption and are supposed to produce cleaner exhaust and lower emissions and give more power too etc etc.

    Sounds too good to be true? Apart from the total cost; that is approx $4300 less the grant, for a patrol. Still its cheaper than $45,000 to generate solar power and sell the excess back to the electricity supplier!

    Who knows what about this stuff?

    Cheers

    apparently you do get quite a bit of increased power with the gas conversion on a diesel motor. I think you need to consider gearbox pressure drive train etc before you fit . you might find problems where your gbox cant handle the increased force applied

    worth checking

    Chimo,
    I had it fitted to my Turbo diesel 3.0l 06 Navara a few months ago. I had it done on the Sunshine coast by Torquegas, it is a slightly different system (more basic) to the one you mention and cost about $2750.
    Yes, the rebate applies and is it $2000. I got it back within a few weeks.

    As far as the system goes, there has been a problem with the Torquegas systems, in that they introduced a new control component last year and have only discovered over this previous summer that the component cannot handle the summer temperature. It results in the gas system cutting out. Naturally i did not know this when mine was fitted, and i have had the problem up until about the last month, when the temperature was hotter. Anyway they are working on a fix.

    As far as performance/economy goes, it definetely improves the power, mine went from 114hp to 122hp at the wheels (dyno figures). The torgue which is not shown on my print out suposably went up by about 40nm.

    I recenty did a comparision of economy on a highway trip (4people in car, no towing), where i did one way on diesel/gas and the return trip on normal diesel (you can turn the gas on and off from the dash).
    Using diesel gas i used 7.3l/100km of diesel + 3.1l/100km of gas = 10.4l/100km total fuel.

    On straight diesel for the return trip i used 8.9l/100km.

    So it basically worked out dollars wise no cheaper with the diesel gas.
    Apparently they say the saving is at its best when towing. I have yet to be able to do a comparision to compare when towing.

    They do claim big savings in running cost, but i think in my vehicles case, because it is so good on fuel to start with (8.9l/100km for a 2tonne 4wd, i consider very good) that the gas does not have as much benefit.

    It does make the vehicle more drivable, ie most 3l turbo 4wds suffer from bad turbo lag when taking of from a stop. The gas gets rid of the lag and it takes off really well now.

    There is a guy in my area with a Patrol 3.0 running the Diesel gas Aust system, i am going to catch up with him to find how his compares to mine.

    Regards,
    XR

    Hi XR650

    Can you give us some feed back regarding the Diesel Gas Aust system when you catch up with the guy?

    thanks again interesting info.

    A friend of mine had gas fitted to his truck doing interstate work and he said that he got better performance out of it but had a lot of trouble with it so he took it off and went back to straight diesel.
    I went to a gas place on the gold coast where brejen was getting gas fitted to his car and enquired about getting gas fitted to the rodeo, 3l t/d, and he said for the cost involved and the little money savings it really not worth the exercise.
    After the rebate from the gov i would still be about $1,000- out of my pocket and to recover that in gas would nearly take the life of the vehicle.
    So i didn't go with the gas but that's my decision. If i had and got that little bit extra power it might have made it just that little bit bettter vehicle when towing.
    Pulling the yalta is a bit hard on it in the hillls but does alright on the flats.
    I am not knocking the fitment of gas as others might have a good run with it, thats just my 2 bobs at this stage.

    Thanks Graeme, I was wondering about the cost benefit as well as the quality of the fit up design and while they may not all be the same technically the pay back time for lower distance travelling units would seem to make the exercise less attractive than first appearances.

    A guy I knew did a DIY job. Used a BBQ bottle straped in the tray! Gave him an obvious poer increase but don't know about economy. Wouldn't recomend DIY though!!

    gee i would of expected a better economy return as you figures give you about 50 cents /100km saving in rough figures
    at that rate it would 200tho it get your money back
    even though 8.9 l/100 km is great
