Best straight LPG setup for carby XF

I've been told that if I find an EFI intake manifold and fit a gasresearch throttlebody then I wouldnt need all the sensors or the ECU.
Can anyone confirm this?

Would that be the best way to get max power from this engine on LPG?

Re: Best straight LPG setup for carby XF

How much benefit does the use of that manifold add over just going with whats there?

Re: Best straight LPG setup for carby XF

I went to visit the guy in Wagga that GasResearch suggested and he told me:
straight gas is pointless - may as well be dual
GR stuff is too expensive and only useful on real high performance applications
GR setup will cost me in excess of $2500
normal dual fuel will be about $1650

I didnt end up with a cleaer answer on the manifold issue from him, but I did find a wrecker with one (manifold) for about $70

back again, i sort of agree, if you love the car and don't ever want problems and plan to keep it a while(IMO XFs are best, not much high tech things to go wrong less rust prone than XEs)
i have and would/will do again, fit an IMPCO duel fuel mixer 300a and impco model L converter gas bloke will know of these adapters to fit are avail, i have 2(sorry not for sale) the benefit of impco suff is two fold, firstly SUPER reliable(in ten years i have NEVER had a problem with impco mixer, converter diaphram goes bung when over 5 years at least) secondly i get 50km more out of a tank with impco compared to current (POS) LANDI set up(car soon to be sold, not getting my good stuff), thirdly power is EXELLENT as this system reliably feeds a stock 351 V8 (don't get any crazy ideas theres a lot of "how do i fit a clevo into XF threads")
a bit more ign timing is enough to bring power to as good as petrol.

Re: Best straight LPG setup for carby XF

Impco is the brand rather than a 'type' of componant?
So u reckon I go dual fuel with the Impco gear?

Does that utilise the efi manifold, or some other arrangement?

Forums rock - how else would I be able to get info from someone who's done it all before!

impco brand sits on top of caby via an adapter(ugly looking bit of gear but WGAF) 300a mixer is used in many different cars via different adaptors from ea CFI to v8 fords and holdens and 6 cyl cars.
so in answer to your question you only remove your air filter assy and fit gas stuff on to carby, i am told there is a impco straight gas mixer you could use with the EFI manifold "if you want" i have seen gas research on EFI manifold and also on standard carby manifold using an adapter(supplied by GRA)
for impco the added cost over a cheap gas conversion could cost around $200 more which i reckon would be WELL worth it.
duel fuel is good IMO as you can't get a jerry can of gas.

Cool - I think Im convinced. :)
I'll see what this guy has to say about impco availability.

Re: Best straight LPG setup for carby XF

Dual fuel on an EFI vehicle doesnt show much of a drop in performance over a dedicated LPG system, but on a carby vehicle the benefits are huge to use the EFI manifold and dedicated LPG as the shitty little carby on them was quite a choker.

I'm guessing, by your mention of sensors, that you have an '87+ XF with EST in the kickpanel for spark control?

With any of the LPG systems, it is always better to have a different ignition curve (the point it starts to advance and how quickly it does it), but you can leave it as it is and use the pre programmed ignition curve in the EST.

From memory I dont think any of the sensors, etc are reliant on the carby being there, all you would have to do is relocate the pipe to the MAP sensor onto the new manifold.


Now about the debate about GasResearch stuff....
Yes the IMPCO gear is extremely reliable, and there are plenty of people out there who know what they are doing in terms of repair and tuning, but the mixers work in such a way that makes them no good for performance applications, they tend to run rich at idle and lean at high RPM.
The GasResearch stuff is a little more expensive to set up initially, but you can often find them in the trading post for a reasonable price, The GRA carbs are a fantastic bit of kit, and from all accounts I have heard about them, they end up more economical and give a decent increase in power too.

GRA themselves do seem to charge a bit of a premium for their time and expertise, but when it comes to their gear, I beleive it is worth paying the extra for them to do it. (see thread Disappointed.... for the reason why I recommend GRA only)
