Re: Nitrous And Lpg

Its very hard to do lowy. Because LPG can't ramp up the fuel delivery to compensate for the nitrous it's a real easy way to blow your engine up!

The only way I can think of doing it would be to keep the fuel tank with an eletric fuel pump that came on just before the nitrous hit. But I have to be honest, i've never seen one done.

Re: Nitrous And Lpg

it has been done before, you have to use liquid gas injection because the nitrous won't mix with gas vapour, the guy who did it used a nos fogger system with liquid gas in one side.

Re: Nitrous And Lpg

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....

Re: Nitrous And Lpg

Re: Nitrous And Lpg

Just a stupid pont to add, because i had considered doing a similar thing.

Running an engine on LPG, checking mixtures are happy through the rpm range, and fitting a conventional plate type wet n2o setup running a seperate fuel tank/pump/lines only to supply the nitrous.

obviously timing, plugs, etc would have to be checked as per usual n2o installations.

dunno, but........

Liquid gas setup?

The reason LPG needs to go through a warm converter is because, in normal form, its so cold it freezes almost instantly when it mixes with air.

Unless the nitrous is changing this in a big way the jets would freeze up in a second.

Re: Nitrous And Lpg

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!!

Re: Nitrous And Lpg

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
