I've been researching LPG conversions for the V8 and I'd like to contact any fellow V8 owners (MG or Rover) who've had it done. I am aware that Ecogas Ltd, who were officially appointed by MG Rover's Research & Development department, have carried out eleven conversions (so they claim) on V8s.
Any of you guys out there?
Let me know.
I have the V6 rather than the V8, but I've also been looking into an LPG conversion. I've got a quote from the Green Fuel Company (www.greenfuel.org.uk (http://www.greenfuel.org.uk/)) that comes in at about £2,200 including VAT which seems reasonable (about a 2 year pay back on my current mileage) and they seem pretty credible.
I'd also welcome any feedback from owners that have had this done and any recommendations of other conversion companies.
try autogas in Thirsk, Nortth Yorks. www.autogas2000.co.uk I think
The important thing to bear in mind with the current crop of phased sequential systems is that in order to maximise the engines performance whilst maintaining reasonable economy the gas injection times have to be based on acquisition, during operation, of the petrol injection times. This is putting it very simply! In essence the gas system needs to understand and, just as importantly, modify the data available to the petrol injection system. So we're talking engine management, performance mapping and software here and it's critical if the conversion is to be a success.
There are as I understand it two systems available in this regard. firstly you have self learn, self programable adaptive systems which will attempt to read the necessary data from the petrol ECU and then convert it as best it can to suit the gas injection system.Or there are 'dedicated' systems which have the gas ECU pre-loaded with data from the factory. For sure the latter has to be the better option as the system will have been developed jointly with the manufacturer. Remember also that your engine management system will for example cut off the supply of petrol to the injectors if your oil pressure falls below a certain level and I know I would want it to do the same when I was on gas.
The problem with MG Rover cars is that there is no longer a source of data. However MGRs research and development department spent some three years developing LPG systems for some of the range alongside a firm called Ecogas Ltd. In all cases they employed Landi Renzo sequencial systems which certainly for the V6 would have been 'dedicated'.
Anyone with a Rover or MG considering a conversion should I feel look at dedicated kits first and Ecogas are the distributors of the Landi Renzo system ( www.ecogas.co.uk (http://www.ecogas.co.uk)). They converted the V8s I know of which is why I'd like to talk to some of the owners.
What's the story with the US based engine family. Mustangs are not usually converted in US, but the same engine could be reused in commercial vehicles. Ford Australia bring out a gas specific modified motor, and won't warrant standard motors with conversions.
