LPG conversion
With all the talk of LPG in the media right now.
Does anyone know if it is possible for rotaries? I don't know anything about lpg and am not interested in this for economy just curiosity. Perhaps it could be directly injected into the chamber in liquid form? That would give good cooling effects. anyone know? fatmarco |
Not sure but the first thing I think of for the 8 is where in hell are you gonna fit the tank? :Freak_ani

I think there are a few LPG rotary's. try ausrotary.com

Yes you can convert a rotary to LPG, but I dont know if anyone has done it with a renesis. Rotaryenvy is correct that you can have a squiz at ausrotary for info on pre Renesis rotaries converted to LPG but I dont believe you will find anything about a renesis. My suggestion is go and have a chat to your local LPG convertor.

whats the diff with a renesis to any other injected rotary?? none
with a rotary however you would need full gas research... |

Happy for you to be the test mule. Andrew |

Happy for you to be the test mule. Andrew I have done several LPG conversions to earlier rotarys and they work well. I once built an 86 mazda 929 with a 13b turbo cosmo motor on gas and I used to tow my caravan with it :) The big problem with the RX-8 will be fitting the tank. |

Can the existing petrol tank be modified to take the gas?? why is there a need to fit another tank . michael |

Maybe my memory is playing tricks on me but isn't our fuel tank a saddlebag type arrangement? I also seem to remember reading somewhere that it's not even steel, let alone of the kind of thickness to accommodate the pressure of LPG.

Dave you are 100% correct but it would give us one hell of a Bang :lol: Michael |
LOL, and I am sure there are a few that would want that bang treated as a warranty issue :-/ Joking :yelrotflm

And let's not forget that this monster tank is not going to do anything good for the 50/50 weight distribution of the 8.. :nono: |

what a f$ckin stupid thread, what moron would honestly even consider converting a rx8 to lpg....
c'mon, get your head out of the clouds... |
RIGHT ON ! :ylsuper:

c'mon, get your head out of the clouds... Nobody's forcing you to read it. Not interested? Then piss off somewhere else. :) As for Mikey's idea - everybody would think you've got a really fat, ugly girlfriend! :mdrmed: |
revolver, if its hypothetical, why don't you try the theory of sticking a shovel up your arse!
lets try converting the rx8 to jet fuel, maybe entirely ethanol? fill the boot up with batteries and make it a hybrid... stop being a post whore and get a life.... |
Thanks for the free advice but my life is just grand thanks. :angel:
Though judging by the venom spitting from your two posts today, it sounds like yours could do with some improving. Cheer up. |

Yes it is a hypothetical.
But as i was reading over at ausrotary thanks to the tips here, someone is trying it with an older rotary engine. You may think it is a stupid idea, but only because you are are limited yourself. If hypothetically, direct liquid injection makes the engine more powerful and more efficient, it would certainly be interesting. Not only to rotary owners today but for the future development of the rotary engine. And there is every indication to suggest that rotaries are well suited to lpg. |

Actually, I think I prefer 'post slut', 'cause from what I can gather, whores get paid. ;) Yes, yes. I know. 'Legal whore' fits. :lol: Back on topic - keep us posted Fat Marco - I'm interested to see how the project being discussed on AusRotary goes. :grouphug: |
Look ... back on track guys ...
... I'm sure most of you will recall that Mazda have road tested a dual-fuel setup on an RX8 using Hydrogen instead of LPG. I'm sure it is completely possible, and our 50/50 weight distribution won't be affected all that much (I reckon it's a bit of a wank job anyway). You could most likely get someone to replace your petrol tank with a custom LPG/CNPG tank so it reduces wear on suspension components. |
