Gas Powered Cossy........
Can a Cossy motor be set up to run on gas........£1.00+ cheaper per litre than Super....I live in Belgium and its 1.58 euro per litre......(£1.36 a litre) Im sure ive read that gas is a higher octane than. petrol.....Any thoughts on this subject..............

jennybravo is a lpg installer by trade if he says its possible it is and i dont see why its anymore difficult that any of the cars he does
infact im willing to bet that a cossie is easyer than alot of modern day cars with sensors that try and change the engine when on gas thinking its still on petrol

Peicher & Voln, have been doing these since 1987!!
They run, or did years ago a 3 door with 580bhp, and over 120,000 K's on the original engine, running solely on gas.
It has/had a 120Litre tank and even at 80% fill(max, to allow for expansion) that is 96Litres.
On some engines you will need to fit DRY FUEL SEATS, which are a nightmare, and the reason for fooling an engine into thinking it is on petrol, when on gas is so it does not default or bring up error codes.

Great info Tabetha, but do we anyone out there in Big BHP CossyLand that is running one on Gas.....on the road.....realiably....... If Stu or Kenny is reading this, could you have some input....Good or Bad.. The cost savings over a period of time will be massive...Ive had my Cossy 20 years.....

I was also wondering about the cooling properties of gas on the crown of the piston. I would have thought the in-cylinder temps would be much greater when running gas.

PassionFord Post Whore!!
I have thought about this on my Cosworth as Im going to be doing a full engine build in the autumn/winter and if anything needs changing internally for gas then now would be a good time to find out
A nice 420-450bhp YB on gas would be perfect.

lpg
It prob needs a sequential lpg installation , with gas injectors next to the fuel injectors, i'm sure we can run these on the same horsepower as compared to petrol , prob even better. as long as there is enough gas injected the engine will not have more heat built up.
Here in holland i do quite a lot of lpg fitting to cars , specially range rovers and other big engines , most customers say , the Rangie runs better on lpg than on fuel.
There are cheap gas systems and expensive gas systems , cheap ones will destroy an engine and expensive ones wont destroy an engine when properly fitted.
Engine management (lpg) is done by ecu's , like adjustable ecu's

It absolutely can be done, but the correct systems installed mapped and fitted to use on a high power turbo car are most likely prohibitively expensive as a fuel saving device on a car that doesnt actually do many miles IMO.
No, ive never actually done one, before anyone asks me, but from what i know of it from our agents who do fit, good systems installed and fitted arent cheap.

lpg
I 'm sure lpg systems do have their own ecu's . and there are a lot of different makes , but i guess a autronic system or a motec systems will do it as well , just make sure you have the right injectors (flow and resistance)

nothing to get heads around mate
jennybravo is a lpg installer by trade if he says its possible it is and i dont see why its anymore difficult that any of the cars he does
infact im willing to bet that a cossie is easyer than alot of modern day cars with sensors that try and change the engine when on gas thinking its still on petrol

I don't know of and ecu's that can run LPG but in theory there is no reason why what is out there couldn't.
I install BRC, Prins and AG systems to all types of vehicles, mainly now concentrating on congestion charge vehicles but we still have a lot of normal vehicles to do.
The AG systems are pre programmed so they would be useless for a conversion, Prins is a very good system although there is not much you can do with it so you certainly wouldn't get much more than gains in economy, the BRC systems would be ideal for the job IMO, the ecu is fully programmable, ignition and fuelling, I have found they don't cope with turbo vehicles as well but a lot of the problems can be ironed out with a few hours of road testing and mapping.
I've done all sorts from Corsa VXR's to tuned Saab turbos and a 600hp F150 truck, non have ever been a problem and they have never been back for anymore than a service.
Phil Price ran his cars on a multipoint system I wouldn't even go near but in all honesty it obviously works or he wouldn't use it.

The more modern V8's need to be on multipoint really, infact we won't install anything but multipoint systems on cars these days.
My own car is on single point though and its well behaved, I've done 50k in it and its never let me down, I just put up with the occasional smell of gas and very occasonal rough running

Quite a few modified 200SXs on the SXOC forum have flashy big spec LPG fuel systems rather than running normal fuel.
Personally id not bother and pray for the day E85 becomes a widespread fuel in the UK, much better.

Now this is something I have been wondering about, is it possible to have LPG on a MK6 RS2000 I4 engine..
as I have been told it's no good for the I4..but i have seen on a site where a guy has converted his granda which has the I4 but the 8v and it runs with no problems....
so is this possible to do this LPG conversion on the RS2000 I4 16v..as if it is, it would be a good idea to have it done.. with the way petrols getting out of control??
