On the setup tested in the ausi 4wd mag they were talking 1/3 the volume of gas to diesel. This means if you have a 83 liter tank you need a 24 liter lpg tank.
Working on there savings figures which used Ausi fuel prices you need 200000km to save the cost of that prof insalled kit but 20% more power would be worth it. NZ fuel prices would probably result in a longer payback.

The guys at Diesel Gas Australia install a gas tank 1/3 of the size of your fuel tank and it usually runs out at the same time.

Am still gonna have a play with it to see how much it improves the power, the other option that the lpg guy gave is to have the bottle in a fully enclosed container mounted in the back that is breathed to the out side, i think this may be the go!!

  Here are the results from my playing, I have run up the truck on two different Dyno's with the same results. These tests were done before I put in the boost switch so I was turning the flow up as the revs were goin up. The other test put me at 73.7kw but did not scan so well. |

I was talking with a mechanic mate.He reckons an Impco lpg unit will do the job.He's got one on his p76 Landrover.Fits on top of the carb inside the air cleaner and uses air flow to vary the gas supply.

Harry, sounds good how about a little more info? Since installing the boost pressure switch the system has worked very well but I would really like to have the amount of LPG going into the engine varied depending on air flow.
Tho after about 1 year of using it on average 20% of the time I have had no problems yet. Have done about 25k in the last year.

That's all he told me.But I'm gonna start working on him.He has a much modified landrover [Cruiser diffs& g/box with p76 leyland up front.Has impco lpg fitted but doesn't use it.I'll try and borrow it [weight saving for him and in the interests of science and power for me.There's one on Trademe at the moment but I think it's too small.The bore size would need to be at least Isuzu intake size which would mean a v8 unit.I'll keep you posted.
Regards,Harry.

Just out of interest with this thread, I worked on a Ford Louiseville (Looseville) truck a few years ago that had its engine converted to LPG (Cat 3306)
They had shaved the pistons down to 13 to 1 comp ratio, replaced the injectors with spark plugs and fitted a distributor in place of the injector pump.
The truck ran very well with no vices so that is another option.
I think the Waipa district council had about 6 of these done and by all accounts it was a succesfull exersize
Cheers

Well its been over 12 months and nearly 30,000km and due the the price of fuel over the last six months I'm using the lpg all the time and still no problems + I have noticed that the oil tends to last longer so I have been done oil changes every 8k for six months now

Is propane injected right after filter, and passes hot turbo? Is it safe?    The above pics show inside the truck where I have a tap to control the flow (if towing and only want a little boost). When 4wd'n in sand I open the tap all the way but for around town towing etc half on is enough. Below the gear lever is two switches, one for the intercooler fan and the other to the lpg circuit. In the engine room I have installed a boost pressure switch (set at 6 psi) that switches on the little blue gas solenoid. The whole system cost me about $300. A small gass bottle is located in the back and I am going to install another gass solenoid straight to the bottle, switched off the ignition. |

Also a friend of mine did the same to his VX cruiser with no problems. His truck has about 160k on the clock.

I would definately install it if I could work out how to automate the cut in cut out of it.
What sized tank are you running now Namic?

I have been looking to run the LPG on my truck for a while now,
Where did you source your boost pressure switch and 12v solenoid valve from? What sort of cost were they?
