Converting My Xr6t To Lpg

[Inducted_Breeze]

oh and I havent got the car back yet...hopefully today!

Well I picked up the T last night and she is now on Direct Injection (Vapour Injection) LPG using the Parnell SVI XR6T kit. Tyson from R.A.G.E Racing in Midvale walked me through what they had done and talked me through refilling the gas, switching between fuels, any error codes/beeps and what to do etc. The manual is very helpful.

He showed me the dyno chart and I have the same power as petrol though the Torque drops of by a milimetre or two towards the top end but it is slightly better on the lower end. Seems to balance out really. The system is by no means maxxed out the money I pay for only seems to get me the same tune as petrol and I need to pay for more dyno time to get more power out of it...sounds fair enough.

So far after 100km's driving the fuel economy is better than my petrol tune so I'm pretty impressed but it's very early days.

No different in feel when driving, cruising, accelerating hard etc.

The engine note sounds a little bit different but not overly noticable. The LPG Injectors are a bit louder than the petrol injectors @ idle but you can barely hear them and when under driving conditions you cant hear them at all.

The car feels a little heavier due to the tank I think but it hasn't effected my driving.

So far highly impressed with the system. Switching from petrol to LPG and back is completely seamless and both tunes go as tough as each other. The workmanship is high quality and R.A.G.E Racing really need to be commended on this!!

Will post pics and Dyno chart when I get home. (I left the chart at the workshop by accident so getting him to post it out...)

Will report back when I have done more KM's...LPG is 58c-64c around home at the moment so bring on the $1 per litre savings....

some piccies of the setup.

The Tank from outside:

The tank from inside with the rear seats folded forward

The fuel cap setup

The Injectors

A short movie of the loudness of the injectors:

Computer and stuff (that I dont know what it is)

Heat Shielded

The display/button setup

The LPG badge

And a plug for the installers...(you can ask for this to not be added to your car)

Impressive setup, job well done

Might be a stupid question...but what happens with the everage fuel readings etc. on the dash/ICC while you're on gas? Does the LPG computer fool the ECU in to thinking that it's still actually the standard injectors running?

[Inducted_Breeze]

from what I was told, the numbers produced on the Ford dash when in LPG mode are wrong and the only way to work out mileage is by when you have emptied a tank...something about the ECU thinking it is pushing through petrol but it isn't so it reads it as better mileage...something like that...

Anyway so far I have gotten 16L per 100km average usage where my petrol was 14.7L per 100 usage...not bad...

On a standard tune I would imagine that economy would be a lot better

Good job,what is the total cost of this conversion & how much would the Government rebate be ?

Hi, everyone!

Firstly, I was read this forum for a time, and is very good

Forgive me,that my english is bad, I just learning it now. I am writing from the other side of the world (Europe), and in our country there are no big australian fords (even americans are very rare), but I love them

Sometimes even with the Net we have problems...

Maybe, you can give me a little help: I have an old car(off topic), petrol and lpg. With my friends we made a turbo conversion on it. On petrol it works well, but no on gas.(it is an old convector vaporiser gas system)

The question is: how works that system, I mean from where knows the convector, how much gas needs the engine, off boost as well as on boost. Or if I change the convector to a bigger one(or put up a second one), it will give too much gas for the engine at lower rpm-s ? how can I fix that?

If somebody of you know the answers, please let me know Or if you have some useful links, I very appreciate

I know, the best way is buying a new injected gas system, but no budget for it ( all, what we made on the car, was in my backyard and in my friends garage )

Thanks

Gday

The whole job cost me $4800. The federal gov't give you $2000 back and in WA the state Gov't give you a further $1000 back,

Cheers

Hey Artimis,

Welcome to the Forums and hello from over in Australia. I'm probably not the best person to answer this, but the symptoms/issues that you are describing is exactly the reason why Turbo cars generally werent put onto LPG until recent advances in direct injection systems came along. There is a separate computer in this case that controls the flow of LPG and unless your computer system is capable of doing this then you have no choice but to upgrade to injected gas. This setup has a set of it's own injectors which is much different to the old mixer technology that you are referring to and these injectors contribute to the control of the gas flow so without them...it might be a bit hard. Putting in another converter will just allow you to pump more gas in you really need a specific computer with injectors that can allow you to control the flow of the gas.

In my first post of this thread I listed the phone number for R.A.G.E Racing. If you wanted to ring overseas to this company I am sure they will be willing to answer your question better for you,

How many Km's are you getting from a tank of LPG ? I'm very interested in the same system. Just need to find some one in sydney who supplies/fits these systems.
