LPG recomendations.

[deaddave72]

As the last LPG thread is now 3 years old, does anyone have any recommendations for carb yank motors? I have one I'm defo going to convert, but would like to know from any other folk here of systems that they have found to be reliable? Its been a few years since i was working in a Landy garage and most of the conversions that came through the door were, how shall we say, didnt install confidence back then about a decade ago. A chap i know has used a marine conversion and sings its praises. So lets hear whats changed in the past decade.

I'd imagine converting to fuel injection would reap similar reduction in fuel costs with less complexity of two fuel systems and scarcity of filling stations.

I use a blos variable mixer and omvl re90 vaporiser on my V8 Range Rover and TR7V8 , not had a problem and they sail through the MOT every year. Changeover with carbs is a bit clunky but they are all like that.

Just check you've got somewhere to buy the LPG first, virtually all the stations round here have stopped selling it.

Tinley Tech will sell you the gear to DIY and certify after inspection.

Ask on the LPG forum too

you would think that, however as i have injected and carb V8s in my fleet, there is hardly any difference in mpg. My Cadillac will get about 23 to 25mpg on a run and the S55 merc gets 27mpg on a run , which is identical to my Carlton GSi LoL. The Dodge is the one i am thinking of changing as I'm making a demountable camper on the back (build thread to come) thus greatly increasing aerodynamic drag. Ive not seen a scarcity of filling stations, in town we have 3 and Andover isnt a big place, most shell garages have lpg that i have noticed on my travels. I guess it depends on where in the country you are.

Going back to the injection route, sure i could source a car, pull engine out,ecu/s,wiring, make an adapter plate to mount to the gearbox, buy a suitable electrical pump to put in fuel line, put a hole in fuel tank to have a return for the injection system, make engine mounts, make exhaust system etc etc ,or fit a small kit of parts in a weekend still drive it to get the system certified and in the space of a few days carry on as normal. Or i could buy a new engine,ecu,mounts,exhaust and gearbox from the states, spend a fortune and still get relatively low mpg. I could convert to diesel as well, have to spend an age doing the conversion and then have the dvla involved, all of which affect the points system to keep the Dodge tax and mot exempt. As you can guess, i have explored many options and have narrowed it down to the one that is the most economic to do and also live with on a basic yank 5.9L V8.

Perhaps owning V8s is a downfall in my car choices

Shell are in the process of pulling LPG out of all their stations, the 3 nearest to me were all shell.

In Holland, the older yanks are mostly running the impco systems without any issues.
This stuff is made for the big v8 carburetors.

I've never converted any of my Yank V8s - I had planned on but changed my mind in the end as I don't use it enough! I do have an Impco 300A Series 50-70 (carb top) mixer for sale though!

LPG is 45ppl if you are close to Birmingham, which annoys me as I'm not....
Would definitely have a home tank if I ever get the space.

Anyway, IMPCO gear usually works very well with big carb engines, in not clued up enough to recommend what you need though. Would go with IMPCO gas carb rather than a BLOS.
