Lotta threads about fuel costs. Anyone got an LPG car?

Pro's and Con's....thoughts, costs etc?

jura 11 has it on his monster wagen. he said its amazing when i saw him at ace cafe

 

if your gonna do it make sure you fit a valve lubrication set-up too. otherwise you'll end up wearing the valves and seats out prematurely

 

Hi matey i'm selling full LPG kit for £600 and for fitting you will pay extra.I know LPGA approved installer which will fit for good price.
Is great if you are running around 300bhp-350bhp,if you want more you will need bigger injectors(BRC are mostly used),mine are Zavolli and these are good up to 350BHP.
I go for bigger BHP(i'm thinking around 450bhp and LPG will be useless,and i probably go for Rotated/Twisted setup)
Yes i recommend Flash Lube kit(i have this),which prolonger life of valves and is good for lubrication of engine,because LPG is dry.

If you have any question,PM me

 

a friend had it on his car but it rooted the heads - I guess as per Rob 84's thread he didn't have the valve lube thing

 

My old Foggy STi was converted to LPG after I sold it. Still went very well with the valve lube kit

 

Flash Lube kit is must,because you can kill you engine at 10k miles

 

Here is dyno printout mine JDM WRX at this time just standard on LPG(map has been tweaked/adjusted several times) .This maybe help.

that seems healthy I might just buy another scoob again what's the highest figure on LPG? And is it reliable?

 

Everything depend on Injectors and Vaporizer,pipework.
If its mapped and fitted properly you don't have any problem,but i say before Flash Lube kit is must....

My friend running 400BHP EVO without any problem several months.Some guys with Nissan running high 400 bhp on LPG.
But i think 400-450BHP will be top.
LPG have own ECU which is possible tweak and will suit to your car.
Somewhere i have recent dyno printout on LPG again after remap,just TD04 and FMIC,full decated exhaust and i make 275bhp.

jura the man....great advise there.......now someone buy his lpg kit

 

can you use an after Market ecu for LPG? it sounds too good to be true

 

No you cannot control with any after market ECU like Simtek,Solaris/Syvecs,GEMS,Link LPG injection,for LPG injection are only available only AC STAG,Prins,BRC and some not well known.

BHP is really depend on injectors and Vaporizer,from this system which i have fitted max power will be 350-400BHP,maybe little more,but if you want more than 400BHP you will need 2 Vaporizers(or single highest rated like Voltran VSGi or these Two,due one is rated to 400BHP) and 4 more injectors(2 injectors per cylinder,Keihin/Prins are highly rated and used)

 

I was very impressed when driving a Scooby at a Welsh Rally School some years back which ran on LPG plus the Mk 1 Escorts also ran on it, they all drove perfectly well.

I assume the downside is a large tank to put in the boot which comprimises space, and how quick you use up the lpg.

I was really interested in doing this, but our nearest LPG is over 30 miles away, I rang around trying to get my own tank installed but no one would do it for household cars they wanted a fleet of 6 or more!!

 

thanks for the info I'm going to look in to it more

 

Keep us posted! Sounds interesting esp since cost of petrol is sky high!

 

I thought about this last year and given the price of petrol and the fact that I dont plan to sell the car I'm thinking about it again!

The gas tank sits in the spare wheel well and might be slightly taller depending on the make of tank, so you might have to build the floor of the boot up slightly and put the spare wheel in the boot. Not really a problem unless you carry a lot of stuff about.

I worked it out that if you are covering 12k miles per year (average for many cars) it would pay for itself in approx one year.

Have heard of people getting tanks for their house but normally under the guise that they use it for their "boat" or similar. Might have something to do with paying the duty on the gas!

 

Hi.
I have LPG conversion on my wrx 03 ppp .done in august.
after when i win auction on ebay im thinking 2weeks do it or not.
I never saw boxer engine with turbo on lpg.
It was experiment and it works.
it takes 3 litres more lpg then petrol on 100miles. power is noticeable down about 26bhp, a "kick" from turbo is around 700/min later then on petrol.on normal daily driving You dont feel it, No You feel it in pocket .
You can switch on petrol during one second or less if You need power in full.
I have 60l cylinder on my.Only one little problem,engine menagment light is on sometimes.
Its happend 2ice during 5 months. engine have to much air or to less lpg when cruising.
first itme 50miles/h 15min period and is on.
second fast driving around 60miles/h on roundabound-straight ,some lady drove from left hand side.breaking- take off side line,im driving around roundabound, push 3rd gear and the same to much air/to less lpg light is on.
I check it via Vag cable and reset Ecu with Learning View.nothing major.

I win auction on ebay for 720 (normal price 900). Company name LPG Wales in Cardiff.
http://www.lpgwales.com call them to make a deal 850 is max what id like to pay.
(i dont know from where jura take it for 600 (used, probably new a lot more) plus fitting 600.
probably they fit it with Gold injectors
900 brand New plus Your choice- in spare wheel space(up to 46litres in spare) or cylinder id like to have 70 but they havent in stock.
I cant say nothing about others but they provide very good quality service and only one day fitting.MY its 2nd subaru which they did first it was sti.
To make it leagal/certificated(my car is registered in DVLA) they must put filler cup in place which will able to withstand the pressure of 60 kg. next as impreza has turbo and has stronger valve seats .
You dont need lubricator(they can explain it better)
flash lube lubricate good only first cylinder and valves.You d like save money not spend.
as impreza is turbo has stronger valve seats.
From suabru only non turbo forester need flash lube,but still flash lube not works like everybody think.

no matter how big is Your turbo if you are still under 300bhp.
every depends from parts,they offer parts up tu 300bhp if You wonna more You need stronger or more(another 4) injectors,vaporizer.
lpg ecu is separate , my is mapped for my prodrive map exactly the same but lpg have more octan but lower calory in litres (more calory in kg but they sell it in litres and that is a reason why is 10% less power(if they will map above prodrive map then maybe will be closer with power to petrol)
i dont know how strong it is on lpg-i havent idea how much power has on petrol. never been on dyno i estimated what i feel under right foot.
with my driving i need 7000 miles to paid me back depends how much You pay for conversion.
road tax is cheaper around 15 or 10pounds. I pay 235 a year.
For people who live in london. after when You convert Your car on lpg take it to station for emission test, probably after it pass(Your car is co2 friendly) is no congestion charge for Your car,i mean You can drive in London centre without charge 8pounds daily.
You dont need Flash lube kit for protection of Valves.
as impreza is turbo has stronger valve seats.
If its helps thats great.
When You fit lpg check how long is warranty (usually 2 years),and for what(parts and labour) some offer live warranty.
how much for service.

 

At first:Probably you don't know,you never get free congestion,you can apply,but never get positive reply.How this i know,i apply and never get positive reply,for free congestion and i live at London.

Second:No Gold Injectors,but Keihin/Matrix Injectors(which are probably best)Vaporizer is rated for 400bhp,price is for LPG kit is probably high,for you,but this company make lots of Subaru,Supercharged Range Rover,when is kit fitted you are get LPG Certificate for your car,price for fitting i just approximately(i don't know how much for fitting,just waiting on quote) and is or will be under £400.Without LPG Certificate is pointless fitting the LPG IMHO

Third:I never get any CEL from driving on LPG,we are drive almost everyday like hard driving,town driving etc.

Fourth: If you want saving money on Flash Lube Kit,its your car,not mine(or other users),but i have and please don't advise this,before you are run more than 30k miles and after you will see if engine make Big bang or just keep running,but why risk?
Manual Flash Lube Kit cost £30-£70 and if you have question just ask on
http://www.lpgforum.co.uk about Flash Lube Kit and everything about the LPG.

Fifth:I don't suspect difference on LPG or Petrol,car has been dyno'ed few times and never we seen drop at power(maybe first time,10-15bhp drop),we are tweak our car more times(now running around 350BHP like petrol and LPG),not just one.If you have fitted and tweaked/suited for your car properly,car worked faultless,like normal Petrol.
And if you know,with full decat you will pass MOT without problem...

Sixth; Power and LPG,to 350-400BHP you will be OK with standard good Vaporizer(some are rated to 400BHP,this depend on LPGA installer),Injectors,pipework(if you have small pipework,which cannot let go more lpg/gas,you never get 400BHP)...


I do little bit own research,before i something post here,please do same,before you want risk your engine.This is same like with question about Exhaust(10 people and 10 people different answer),Remap,ECU etc.

First: You need to do test lpg kit (not mot) to apply after for free congestion in london. certificate is not enough.

second: Read correctly I wrote my car is registered in DVLA ( it cant be done without certificate) and next on other post you wrote you know place where they fit for 600 not 400.
third: You are only the one on the world without engine menagment light on, when driving on lpg. but still is not worth another 500 hundred more with installation for used kit.
fourth :i dont care about flash lube which one dont work like should be.(flash lube is only for vealves seats its helps stop burning seats but impreza like every turbo engine have harder seats and You dont need it.You can use it with petrol engine if You scared to. Please read a little and take opinion from few installers before post(do You catch always what mechanic tell You,they need to sell it, take money from You,they base on what You scared.
every 1000miles i save 100 x30 is 3000 for engine job if it bang.

fifth like i wrote is possible map lpg over petrol map and it will be similar power.
how many times You tweaked -how much is cost for others and where is sens to put lpg and spend money for tweaking(spend another money ?)

sixth: better idea tweak it for petrol only.stay with standard lpg 10% is not a lot. but when need power switch on petrol.(like in BMW M5 normally 400 switch button 500bhp) switch when You need but still save money that is a reason why some put lpg to cars.
and seven You put wrong gas kit to Your car, for hard driving should be NOS

 

@fawor
can you tell me your experience with lpg now after 7 months of use?I am thinking to convert my wrx my2005 but dont know what type to use,some say the ICOM JTG (5th generation) is the best for turbos.Any suggestion?

 

There's some more info in this thread

I have LPG on my twin turbo legacy, it's great but I must emphasise FLASH LUBE IS A MUST, and dont' let it run low. I've recently change the HG on the car after approx 12,000 miles on LPG and the valve clearances were down to nothing. An identical engine from another twin turbo legacy had hardly any wear.

If the LPG is mapped well power loss is negligable if at all.

LPG ECU will follow your petrol ECU, so if you get your car re-mapped on the standard ECU the LPG will follow, assuming it's injectors etc can supply enough fuel.
