Lpg Installers & Thoughts

[d00dz]

Well might as well give this a stab.

Since everyone knows the government and its plan for LPG in cars.

Does anyone know places in Sydney to have their car installed with LPG?

And if so prices would be good. Mates rates would be good too

Prices have probably doubled since the government's announcement.

Been thinking about this for the Corolla.

What are everyone's ideas?

Thanks

wouldnt be bad i want to do this to my Navara

one of the guys here just got an LPG conversion for a v6 commonwhore. I think it was $4k or something.

What I can't get over is the fact that the LPG technology they convert your car to use was designed back in the 60's.

yer LPG is 50% cheaper at the pump but i think same amount of unleaded will go 30% further?

LPG systems are a joke. why you want to convert a decent EFI car to one with a half arsed carby set-up is beyond me. just to "maybe" save a few bucks and spend your time driving around in a backfiring, hard to start car that smells like fart.

big thumbs up!

[d00dz]

True.. Spend what 4k on a fuel system and get 2k back which means you have to fork out 2k on the actual install,

2k of fuel prolly lasts a long time...

hmm

[Beer Baron]

at least then your lame trdy plate might make a little sense as every time you drive past someone with think the person walking in front of them just filled his nappy.

haha, man i am cruel.

actually, with petrol prices these days and the inevitable increase predicted with the coming months and if you fill up for $80 a tank (bp ultimate) a week it would take roughly 20 weeks to spend that money. that's less than 6 months.

my question though is will converting to lpg decrease a car's performance? ie. skylines in particular (apart from the increased weight of the tank)??

[benm]

LPG burns cooler and is a higher octane.

I've been wanting to get it done on my work Hiace because I do over 1,100km/wk (would save more than $110/wk).

[cowie165]

$80 tank x 20 weeks = $1600

That figure isn't where you should be interested - you should look at your fuel savings per week then divide that into $2000 to find how long it'd take you to break even.

[d00dz]

hmm see that TT report how gas car explode? lol weird... how only now they show it. Is it one of those slow news days?

haha richard, rolla's rock

[Marsss]

they showed that a long time ago... they're just recycling

The general rule of thumb is that you lose around 5% power going from petrol to LPG. Not sure if its the same for turbo cars, since most people who do it tend to run NA engines.

If it burns cooler at a higher octane, you can always offset this by running more boost.

Saw an article in some HPI or Zoom mag. I only briefly read it though and can't remember exactly what it said.

But the gist of it went:

There's a workshop in Queensland that's actually developing a proper LPG system.

The owner of the shop has converted his BA xr6 turbo to run on petrol and LPG but with proper injection and engine management (different to the normal, "lets blow lpg down the f**king intake pipe and take a brand new engine and make it run like it was designed in the 60's").

After tuning the car apparently makes more torque down low, and switches to petrol seemlessly up high in the rev range to give better top end, or something.

[Abo Bob]

Freaky. I remember putting gas a couple of old v8's I owned. The peak torque area moved UP about 1000 revs.

Also I don't think unleaded takes you 30% further, LPG is something like 8-10% less efficient without making other changes to the engine, eg ecu and cams.

I thought it actally burned hotter than petrol which was why one of the age old drawbacks of it was burnt out valves, particularly on engines designed to run on leaded fuel without hardened valve seats.

[Abo Bob]

Just had a bit of a read of the gas research site. Check the technical section and the FAQ for some info on forced induction.

[shif_tea]

There was a guy on the forums a while ago building up an engine in his line which he was going to run on dedicated LPG. He said they were looking at 10-15% increase in power due to higher octane rating of gas. Sounded like he had done his research, but i dont' know a whole lot about it except that i've seen it on dual fuel systems and it runs like a dog.

However i would be interested if they proved it would run nicely, and save a bit of money (considering LPG is almost 1/3 the price of petrol now)

[Jimbo2000]

correct

from what i hear dedicated lpg is better for performance (120RON or whatever) but dual fuel is poopsicle

[jonjon]

$80 tank x 20 weeks = $1600

apologies for not being clear with the calculation. the reason i estimated this price is because the money it will cost to fill up a tank will increase over the next 6 months.

anyways, i agree with what shif-tea..
