Oh yeah! :mrgreen:

My D9 is running smoothly on LPG for four years now.
Didn´t have one single problem with it.

The LPG system is from Vialle (Dutch manufacturer) and is of the liquid injection type.
Meaning that the fuel is injected into the cylinders as a liquid. My peug has the same performance on LPG as it has on petrol. :wink:

My tubby was fitted with an LPG conversion, but it got taken out prior to my purchase for some reason :(

Oops, my dad's been over here for a week and I've missed loads. He's 75 but you wouldn't believe it, he's worn me out! At least we've got plenty done, my bro and his family are over here in a couple of weeks and I'll have to drop everything and become a tour guide :frown:

Sooo...

I'm told the cost of a conversion is getting on for 2,000 pounds in the UK and I don't think there are that many gas stations selling the stuff, so there's not many converted cars about. It's about half that over here (less in Bosnia, so I'm told, but the system must be fitted by an approved garage with certificates etc so there's no going to there to get it done, the bastards :evil: ) and stations selling the stuff are all over the place. I'm still kicking myself for not taking the plunge by buying a petrol car and getting it converted. "Why go through all the agro?" I said to myself, then the price of diesel went mental :x :x Still, if I had done then the price of lpg would have gone stupid, Sod's Law innit.

I read cars drop a little consumption running lpg (5%?) but not necessarily performance, this still would make it less than half the price of petrol or diesel (just over half price in the UK)

Sticking a few figures into a few of the many calculators ('cos I'm a lazy b'stard :cheesy: ), 10,000 miles per annum, 30 mpg, an lpg conversion in the UK should pay for itself in about three years. Increase that to 30,000 miles per annum and it'll only take a year!

Over here, at 10,000 miles per annum it would only take just over a year (bangs head against wall) Stupid, stupid...

And this doesn't take into account all the potential problems with the plethora of temperamental emission control systems on modern diesel engines (how much is a new fap??)

Probably because they got more money by selling it and the car separately. :evil: Actually, I see loads of conversion places saying they can't do turbocharged cars, while others don't say anything, making me assume they don't want to mention their shortcomings but maybe I can get that turbo Forrester after all... I suppose it depends on the type of conversion so a bit of research before hand might be a good idea.

"But I'll loose all my load space!" I hear you cry. Actually, a neighbour of mine has the biggest tank he could find in a Renault 5 and hasn't got any space. But he uses the car for commuting and goes months without needing to fill up! There's always the torodail tank that goes in place of the spare, my 406's tyres are 205/60 15, which gives a space of 648mm x 205mm, big enough for a 40-50 litre tank. All you need is a tin of that tyre foam but I always wonder what the look on the tyre repairer's face will be when you tell him the tyre's filled with foam... I've also seen conversions where they fit a smaller petrol tank and a gas cylinder along side it, that'll be even more expensive. I guess risking the wrath of the Quick Fit man is a small price to pay for cheating the chancellor.

Incidently, they do a verticle toroidal tank to fit the spare wheel holders they have on the back doors of most 4x4s, which kind of makes you wonder what happens if someone drives into the back of you. However I do read that these toroidal tanks are pretty indestructable, they can even blow dents out of them using a few (hundred!) bars of compressed air.

Oh crap, I better go and do something useful.

Any thoughts?

Old post resurection!!!
Im in talks with a guy who fits LPG systems in yorkshire, i asked the question about performance tuning with LPG and it turns out i was pretty close to the mark.
with my 8 valve tubby if i wanted to make some more power conventially, I would need to-

Fit uprated fuel pump in the tank
Fit adjustable fuel pressure regulator
fit aftermarket ECU / 3 bar map sensor
Fit larger injectors.
Large alloy fornt mounted intercooler
GT28RS turbo
DP engioneering exhaust manifold / downpipe
free flowing exhaust system
forged pistons
ARP rod bolts
etc etc

Now with a fully mapable sequential LPG system, I dont need bigger injectors, FPR, or even aftermarket ECU! as when the EMS is in closed loop mode the LPG system reads the standard ecu for its base maps. and when boost is used and the system goes open loop (o2 sensor bypass) the LPG systems refers to its own "Mapped" state
So the only mode i would still need to use would be.

Large alloy front mounted intercooler
GT28RS
DP exhaust manifold and downpipe
forged pistons
ARP rod bolts
etc etc

But for basic states of tune ie up to the max of the standard or hybrid turbo the LPG can take care of all the fueling you would require. Even if i wanted to run silly boost with big turbo, forged pistons, steel rods etc etc. the same LPG system can still cater for all the fueling :cheesy:

Now some of the myths about LPG

LPG will burn out the valves,
If you use a flash lube system this wont happeen.

LPG lowers performance,
LPG has a higher octane rating than petrol at around 114!! Here is a quote from Simon Andrews of Yorkshire Autogas

"it's anti-knock properties are sky high. You can run much more advance or boost with LPG than with petrol. So you may not need to retard the ignition even at higher boosts.

I'll give you an example. On a Volvo T5, the boost is controlled by the ECU which starts to back boost off when it detects detonation via the knock sensors. When running on LPG, T5s are more powerful than on petrol - because the higher octane rating means no knocking so the system just keeps on boosting!"

LPG does less to the gallon than petrol.
Yeah it does cant argue with that lol! but not by much :oops:

Im definately going to fitting LPG at some point soon when ive done all my research, i just needed to blurt something out before i burst lol! :mrgreen:

I think that also puts pay to the number one myth - you can't fit lpg to a turbocharged engine.
