Its here people. LPG LIQUID injection has been released to selected fitters. The LPG is injected as a liquid into the manifold, this freezes the incomming air (effectivly chemical intercooling and supercharging) and will give performance gains on any engine, especially forced induction. I saw it with my own eyes. XR6 T 18RWKW gain over petrol with no tune whatsoever. Once tunes are optimised the figure could be as high as an extra 25 to 30 RWKW!!!! Here are some pics. VE calais 6L XR6T Some original photos have not been recovered yet.

These two you see are duel fuel. The can be run straight. I will be coupling it with my Profire ECU's. There is a LOOOONG wait with me ATM. You would be looking at at least 4 months. And for now I will only do the Kits they have on offer, and after 6 to 8 months I will look at doing odd cars with universal kits. I need to play with my project first and get that smokin.

If you like PM me your details and I will see what I can do. I am not here to drum up business. (I have more than I could ever handle, and am sick to death of working till 3am all the time) I mearly posted this set up to let everyone know what is cutting edge in LPG at the moment. Expect to pay around $500 more than vapor injection. And with odd set ups it will be more. Quote: Originally Posted by SRBMUU rebate is endiing? you serious when! Rebate IS NOT ENDING. There has been an extra 19 million allocated to it this year. It is not going anywhere. Don't panic.

Sounds interesting, and with petrol prices on the rise it's something i'm sure a lot of people will be doing soon enough. I'd love to get the VL on this, no EPA's FTW What sort of power are these sort of fuel systems rated to? I've heard of gas injection being able to supply enough fuel to see over 1000hp comfortably. And last of all, the current kit's/setups you got, they fit up to the RB30et's? or would it be a "odd" setup thus costing more? Some original photos have not been recovered yet.

Yep so far it will be classed as a odd set up. The supplier is conv=centrating on new cars and after a while they will let us purchase universal 6 cyl kits that we have to configure ourselves.

so how did they get around it freezing which i heard was the main problem with liquid inj,or is that a trade secret???

can this be run as a dedicated gas set-up?? and what power could that support...

blownbaArchived member
yes can be run dedicated. The sky is the limit, literally. If the injectors max out ( highly unlikely as they are siemans DEKA injectors, the same as high flow petrol ones) you can run a second set if you run a Profire ECU to control engine. Then if the fuel flow maxes out (highly unlikely with the high flow Walbro pump that is currently being used)

Now this is some awsome stuff Can you tune your Profire ECU to meet emmisions so the universal kit can be engineered in whatever car it may be in???

Yes. and with liquid injectionit will FAR surpass Euro 3. All the kits that have been tested actually exceed Euro 4!!!! The only problem with doing custom installs on vehicles newer than Jan 04 is that they need to be emission certified. To get the test done in Melbourne will send you broke, whereas it is free in Sydney. So all my suppliers will truck the cars up to Sydney to do the testing. And once that kit is certified, no other ones need to be done, as long as the tune remains the same and the kit is not modified at all.

i asked my installer about the liquid injection he said there isnt much difference and he has it installed on his car :S what would you do to change a vapour injection to liquid injection?

lol man theres is heaps of difference! (vapor vs liquid) liquid injection promotes all that is good about gas when gas is already in vapor form it loses alot of its cooling properties as it doesn't atomize like a liquid during combustion. as gas is such a cold liquid when its injected, as said above, it cools the intake charge incredibly, which increases torque and power, right through the rev range and is a great benefit for FI!
