Hi all, what's the best system for lpg at the moment but keeping the cost of purchase within a tight budget.
What do people have on there cars and how would you rate your system for economy and reliability. Also do lpg systems get tested at mot time.
Thanks
Mark

I use AC Stag 300 Plus on both of my V6 Omegas. Far from the best, but dirt cheap, and available for DIY, and the setup/configuration software is easily obtained.
Premium systems, such as Prins, have their distribution tightly controlled only to authorised fitters, and the software is not available.
-
Just as a guide ... DIY with the kit mentioned above costs around £700 IIRC ... :)
my BRC system, fitted, 4 years back .. £2200 ... :(
Savings run at around 38% or 10 - 12p/mile (ish)
Mine has been extremely reliable and has saved me a fortune over 4 years.
MOT emissions are done on the fuel it is running on when presented .. so if its on LPG its tested on LPG .. simplees. The actual install is not an MOT test item, AFAIK.
Car needs to be certified and on the UKLPG register to get insurance with most companies, registering with DVLC gets the V5C changed to dual fuel and saves a wacking great £10 a year for most omegas

Only for 'emissions based' tax, ie 2001 onwards.

Define best?
Prins IMO. But expensive and approved installer only.

For me, the Stag is 'best' in that there is a fair amount of knowledge on here, and the software is available. Although clearly not the 'best' from a purely technical viewpoint.

Thanks
Mark

Have a PM chat with Lazydocker.He is probably the best person to advise,and may be able to get you a better price on a stag system. ;)

thanks matey, i forgot to put in i got the telio name to contact from lazydocker :)

Right.... If you can get the kit from Teilo then do because it will have everything you need (except perhaps some spreader plates and washers ::)) My conversion cost me £885.80 completed and inspected (plus some Curry ::)) but I actually bought more tank mounting gear than I needed to in the end.
Tanks: The largest you can get into the estate wheel well (with a little modification) is a 76L GZWM Tank (4 Hole) with a Stako Gas Tight Box. This also required raising the boot floor by about 4". That's a 650mm diameter by 270mm deep tank. It gives a range of anywhere from 200 miles (or less :-[) around town and 280-300 miles on a run when driven quite hard :-X
If you don't want to raise the boot floor then you will (almost certainly) have to go down a diameter size as well so you'd probably only get about 45L tank or so (which would be useless for range IMHO) :-\
The advantage of the Stag kit is that we have good knowledge of it on here and you aren't a million miles from me if you get stuck ;)
Be warned though... Stag only refers to the ECU ;) You need to make sure the injectors and the vaporiser/reducer are up to the job too! This is where we went through some trial and error to find a kit that works ;) Mine (and others) is converted with a KME Gold Reducer and AC Injectors (although these may not be available any more) and pulls cleanly right to the red line :y
-
Oh, and all of those cheap kits you have selected are not complete ;)
-
that would be about right for me lol. that's why im on here as im happy to take advice from people with more experience than me so i don't make to many mistakes ;)
i messaged telio so hope for a reply on that one soon
-
best kit is the worst with an incompetent installer..
choose the best installer first :y
-
Both mine were sub £600, complete with everything, and another £100 for the safety test/certification. I obviously use cylinder tanks in my saloon, which are cheaper.
As LD says, the most successful Stag setup we've found so far is AC Stag 300 plus ECU, KME gold vapouriser and AC injectors drilled to 2.2mm. Some of the other Stag variations suffer a lag on autos during redline gear changes. Tunnie has a Stag on his 2.2, bought from some ebay seller, and its shite, simply because the other components cannot manage the required flow. Anything over about 4k rpm, and its clearly grumpy, before it gives up and flicks back to petrol.
Not sure how much of the 'known good' AC Stag/KME Gold setup Teilo can still get. He is also really hard to get hold of - don't bother emailing or leaving messages with the (virtual) reception, you need to keep trying, and physically speak to him.

As I told him when we fitted it, and we told him when we calibrated it. Fortunately with Tunnie's driving style 4k RPM is way more than it ever sees ::)

He still has most of it, although how long for I don't know. He's moving across to a different brand which he says is good :-\
As for contacting him, I have given different details out this time as the virtual reception and number associated with it no longer exist ;) Once you manage to speak to him he's normally quite good, but not always ::)

Except when he makes me drive it, as a punishment :'(

Your safe for now its untaxed and no MOT. But my trusty steed will ride again soon :)

blimey, the setup can be quite hit and miss then. :-\

With the right components it's fine ;)

ok so if i start getting resources together with the Stag setup you have found so far and as described above and if i cant get anywhere with the telio route should i start asking lpg companies for the AC Stag 300 plus ECU, KME gold vapouriser and AC injectors ect and ill go for range as well so ill lift the floor to get the larger tank in :)
-
mines got a prinns vsi system on it and even that suffers lag on the redline, if giving large have to back off when close to it to let it select next gear then boot again, ive got used to it now but is a good system and never given any other bother in past 15k miles

I wouldn't expect that of a Prins system, if it was installed and setup properly :-\

Yes take it back and tell them to sort it. Has it always had the problem? Or did It gradually creep in gradually?
-
As said, that's not right! :-\ Mine's a Prins system and you can't tell the difference between petrol and LPG! :) and incidently has done about 165,000 miles since conversion! :y
-
was on the car when i bought it, got all the paperwork from installers
-
Can anyone substantiate wether lack of lubrication from the lpg as a fuel will half the life of the engine

The GM V6 engines do not need flashlube

on some other Marques It will. I believe GM valve seats are hard enough, citainly there's no issue with the omega engines. There's loads of LPG cars on here, and only one has Flashlube installed afaik. ...and that was only because it came with the kit.
Some fords and I know of one land rover that had real issues running on gas. BMW's it can be very difficult to keep the engine management happy, although will run fine.
But all depends on keeping the map and trims correct, and making cirtain it doesn't run lean. Something some approved installers neglect completely.
-
That's fine thank you all. It was something someone told me and I thought I'd double check.

I have a 90ltr tank behind the rear seat, returns approx 400 miles range.

That's about right for a 4pot driven gently ;) I could get just shy of 400 miles on a fast run in my 3.0 saloon from my 90L tank ;)

380 miles without running out travelling the length of Europe. That was all Autostradabahn (fill up to fill up), cruising between 95 and 130mph, although I must admit the majority of it was around the 105mph mark ;)
-
I've got to keep the floor space of the estate so I'll go for lazydocker route and lift the floor a few inches and get a 76l tank in wheel well
