LPG conversion.

[Ed]

With the hefty cost of fuel and a thirsty V8 i reckon i may convert to LPG.

problem.. ive got a wagon and need a small tank.

anybody here with a donut or triple tank in a car?

how big are they physically and in litres?

I am thinking of hiding it in the drop tank by cutting out the top and bracing it internally.

there is also a new technology about to emerge "gas injection" where it usees existing ECU for EFI computer.

any guide on tank sizes would be great.  I have had a LPG vehicle previously, that was only a 202 using existing gas ring technology.

Gas research do some nice setups..... my brother got quoted $2500 including tank, filler valve, lines, throttle body, twin convertors, fitted and dyno tuned, ready to drive out.

Looking at the new LPG rebate, ( some discussion on this here: http://www.calaisturbo.com.au/showthread.php?t=84372)

i would say that straight gas or duel fuel is the way to go.... sorry i couldnt help any further....


the way things are goin our v8 fc is going to end up on gas

[Ed]

my bros car is a straight gas EH with a 179 and its tops on fuel.

ive had a duel fule bedford van before and now i reckon a straight gas FE would be excellent.

there is new injection gas technology emerging so i am holding off until that.

im hoping if i cut the lid out of my streeneat tank it will be large enough to conceal a LPG donut tank.  initial google research suggests a donut tank can be anywhere between 600 and 720 daimeter and from 200 - 350mm tall.

now i would prolly need at least a 70 litre tank (56 Litre) LPG capacity, and going off my current fuel range (and allowing 30% extra for LPG burn) that may get me about 250 kms.

250kms is enough.. approx bike range which is annoying but coud put up with it.

i do not want to use current LPG technology tho, it is outdated IMO. LPG displaces oxygen in the manifold and reduces efficiency.

just some thoughts at this stage...

In case anyone is interested, Ausindustry is where you will find all the information on the new LPG conversion grants recently announced by the Govt.  All the rules/regs, application forms etc can be found here:

CRUZIN WITH LPG

ps my mate has a fc wagon with lpg will see  how he done it if ya like

[Ed]

HEy Crashbox,

that sounds promising.. I forgot to measure up my wagon tank last nite for space.

Where did you put your spare tyre in your HD?

I am planning to run LPG only (if i do it), so the entire fuel system will come out and be replaced with the LPG hose.

my only requirement is it must not look like it is running LPG.  the only giveaway may be the convertor.  hopefully the new injection style systems wont have a huge convertor.

where did you get your donut tank?  

Cheers

 Just a thought Ed , why cut the guts out of a perfectly good fuel tank ? Could you get a cover folded up to hide the tank and sell the existing one to recoup some of the conversion costs?

[Ed]

Good idea Blacky,

the tank I have is a beaut fit and I am pretty sure to get one folded up to this quality would be difficult but not impossible.

Guess I could always speak to Marty Dean again.

Ed, check out the latest Street Machine, the Dodge step-side setup is very neat, although it is "old lpg technology"  .
The Gasresearch carbs have a good rep and last time I saw one, they look a little like an EFI throttle body.

[Ed]

will check it out stinky when i get it.

have a look at this link.. this is waht im waiting for.
injection that uses your existing ECU.

I wont go to LPG if it means an additional ECU or it renders my EFI obsolete.  it is self defeating, after all the trouble of wiring it up and mapping it to back to old tech is a step backwards.

have a read of this.... Aussie built to boot!!!!
