Lpg Conversion

[malcx]

I was considering converting my T to run on LPG. Can anyone give me some advice on where to go in Melbourne to get the conversion done?

After the conversion, I want to get the power back to somewhere above factory. Does anyone specalise in LPG and performance mods that can make this happen for me????

Jeff will be your man here, as he has LPG and a Turbo combined on his ute.

I dont know a great deal, but ill give it a shot anyhow.

I doubt you will get the same performance outta LPG as you do petrol, as LPG cant fill the combustion chamber as efficiently as petrol can. If you can find someone who will do direct LPG injection, then you will definately get more perfromance out of your T than petrol! You will need some form of edit/piggy to drive the LPG injectors. My tuner guy is currently in the middle of doing a LPG injection conversion on his T.

Dont take the above as gospel, as my expertise certainly isnt in LPG applications. LPG should be used for central ducted heating and BBQ's IMHO! But considering petrol will be $1.40 per litre soon, I can understand why. I filled my taxi runaround up last night, LPG was 37cpl, so it cost me $17.90....... cheap as!

Hope this helps.

I was also thinking of converting my ute to LPG as I couldnt find one from the factory 2nd hand when I bought mine.

I recently came across this http://www.gas-injection.com/index.html

Its a new form of converting to lpg by fitting new injectors that run off the ford ecu, thinking it is still running petrol injectors, no piggy back ecu is required. In most cases they have increased output power levels

The only problem is that it still isnt readily available yet another 12-18 months away. I had a rough price estimated for my ute at $2500-3000.

hope it helps u. lets us know how u travel with your research

You'd be wanting to track down info on the Liquiphase technology, and it's similar derivations.

You will definatelly find people workign on LPG injection systems but you'll also discover that development in the area is far from cheap. Not many people have established a range of "off the shelf" parts up for higfh [performance applications.

Expect a lot of custom fabrication and possibly a few unexpected explosiosn along the way

This is an area I have had interest in for quite a while. This is what I have found through mainly research on the net, but also by talking to a few people who work in the LPG autogas industry:

Liquiphase seems to have disappeared after promising a lot!

There are both liquid and gaseous injection systems on the market in Europe where gas is cheaper and petrol is like liquid gold. All the systems seem to be made for small capacity engines.

There is a guy in the USA who is/was marketing liquid propane injection systems for large pickup trucks (V10's no less!!).

A guy (in Sydney?) has just started to market a gaseous injection system that I think may be the one mentioned by eMPee. Seen on the ABC's 'New Inventors' recently.

One think is for sure. Only some sort of computer controled injection is worth the effort. Non injection systems have too many serious (explosive) quirks for a modern turbo engine IMHO.

IMHO, The big advantages of LPG in a turbo are:

1. Propane has a very high octane rating. - Yeeehaa. Turn up that BOOST! (unfortunately - our Autogas usually has a lot of Butane mixed with it which lowers the octane a lot but it is still higher than Optimax.)

2. This is potentially the BIGGIE! If you inject liquid Propane into the inlet port, as it converts to gas it takes a huge amount of heat from the air around it. Instant intercooling!! - Yeehaa. Turn up that BOOST!

I have observed that numerous attempts at commercialising LIQUID LPG injection have failed over recent years in OZ. This has led me to believe there are some very difficult problems to overcome but no-one seems able, or willing to disclose what they are.

I am sure if the problems could be overcome Ford and Expensive Daewoo would be pumping out LPG injected Taxis already. They are not............

Remember the LPG dedicated Falcons have stronger rods as well. So.... You may have some more serious internal mods to consider.

This system was actually covered on 'The New Inventors' program on the ABC a few months ago. Looks quite promising.

Does the factory e-gas system use lpg injection?

You might find some good readiing on that site.

LPG actually fills the chambers more quickly than petrol. Remember at room temp it is a gas by nature. It is is stored under pressure to keep it in a liguid state - as soon as it leaves the convertor it is already in a gaseous form - long before it's introductiohn to the cylinder. Also it has a much higher "octane" level than petrol so you can run higher effective cylinder pressure and more agressive timing. However for optimising on the BA six IMO it would be absolutely imperitiave to be able to control the cam timing separately and much more agressively than the Ford ECU does.

BUT it is a very worthwhile avenue to pursue as petrol is only going to become dearer - I can't see it ever dropping back under $1.00. The govts and oil companies are simply too greedy to let it happen.

Thanks for all the feedback!

I have now been quoted "upto" $5k for an injection system from a place in Melbourne that gas research put me on to. They tell me the "upto" is for the "experimentation" that they must do on on the car.

I still havent decided if its worth spending $5k on a car that's already done 50,000k's???

I'll let you know if I decide to take the plunge!

So they want you to pay for their R&D? Tell them to stick it up their effing ass the slack pricks.

that's the Australian aftermarket industry for you....
