anyone know of someone that I could talk to to find out more about setting this up?, I have all the nitrous setup from when I was running the old engine in the ute, it seems a shame for it to be sitting in the shed doing nothing....
There are a couple of different liquid LPG injection systems out there. Liquiphase is still in the development phase and there is an Italian company called SprintGas (http://www.sprintgas.com/ievrs4.html the website is in Italian)that does an LPG injection system. There is also a company in the USA called Biphase (http://www.bi-phase.com/publish/default.htm) that does one but I don't know much about that one yet. You are right that the LPG is bloody cold when it is injected in its liquid state but that has an intercooling effect so liquid LPG injection is great for forced induction engines. Even on normally aspirated engines they are claiming as much as 21% more HP and torque across the entire power curve than LPG mixers.
This technology is still in it's infancy so is not really worth jumping into just yet but in a few years it should be the duck's guts!!
There are two types of fools.
The first, who thinks that because it is old, it is good
And the second, who thinks that because it is new, it is better.
iv'e done it before just used the std pump on the engine and a 100 hp jets with a gra lpg system, i know the knockers will say i need an elec pump but engine was coming out and i wanted to try it. Never hurt anything, so i can't see if you used a good pump you couldn't do it long term
