Going To Gas ?

[MikeW]

Hello

I have a lovely RR 1992 Classic which I have driven as my everyday vehicle for three years now and its fantastic !
I am thinking about converting to gas for all the obvious reasons but have heard stories that it can bugger up the running of the vehicle back firing etc etc.
Could one of you guys give me your views on the LPG conversion ? and also if you have some reccomended fitters either on the Sunshine Coast or Brisbane....many thanks

Hi there,

Ive had several RRC on LPG
IMHO ive found the best standard system is to have a proper gas mixer.
It will run from the Gas coverter into the mixer and then into the plentium chamber.
On my RR, between the mixer and the plentium chamber is a cage like cylinder with holes in it, which fits a stubbie holder (wetsuit stuff) on it like a glove.
If it happens to backfire, the pressure blows out the cage thats covered by the stubbie holder, and doesn't damage anything else.
LPG fitters would be in the know about these and similar solutions.

They generally don't backfire unless there is a problem somewhere, or your trying to accelerate when starting.

The other option is gas injection, better again but big $$$

Thanks Rover8 ......

That engine converts well to LPG, they love it & run well on it.
A good converter will probably insist on new leads & different heat range spark plugs.
Nuff said.:)

go here Gas Research (http://www.gasresearch.com.au/)

Mention to your chosen gas fitter that you have been recommended to fit an AMR brand gas mixer ring, part number M353, they have a much larger flow size than anything listed to fit the RR, I have installed quite a few. They need only a bit of grinding to make them fit.

Thanks guys will be able to at least sound like I know what I am talking about now...............will update as I progress

My system originally fitted at Caloundra but was not impressed with their service. Repco bloke at Zillmere sorted mine out, gave me a few tips too. ph 32651818

I've had 3 gas systems fitted to different cars. GO THE GAS INJECTION !!!
The cost of an old style system is about 2500 (minus govt. 2k rebate= 500) whereas the newer gas injection does cost 4-4500($2500 after rebate) BUT is so much better, smoother,MORE POWERFUL!, never backfires, more economical, and once tuned( has it's own comp to control gas flow) does not make you car smell like an old taxi with excess lpg flowing out the exhaust!
With the old system you, lose around 15-20% of the cars power and the fuel use goes up by at least 25-50% whereas with the injection the power loss is about 5% (you'd only notice it on a dyno) and fuel use is within 15% of petrol usage.
e.g my old system uses about 13l/100k's petrol and 18-20l/100ks's gas.
My injection system uses 12l/100k's petrol and 14-15l/100k's gas.

Another vote for gas injection here. I have a D1 with a 4.6 to which I added gas injection about 2 years ago. I cannot notice any difference in economy or power between the fuels.
I certainly can notice a difference to my bank balance though, both a negative with the initial cost but then a positive with the fuel $$ savings

Thanks guys for all the advice and I am convinced on the gas injection route. The next question is does anyone know a great supplier and fitter ....I live in Noosa and prepared to travel for a good quality job?


Cheers Mike
