k24 on gas

[aznstyler]

what do you guys rkn? im thinking of converting my 2004 crv to gas

[Lukey]

why??

[Alexplicit]

i reckon its rediculous. there great on fuel :)

[mugen_ctr]

I thought the general rule of thumb is anything bigger than 3 liters, or 6 cylinders than its justifiable... cause supposedly its best on larger capacity engines from what a mech told me, id think it have to be a dual, gas an fuel type gas conversion, same system with all falcodores run, if u were to do it, so once a month petrol has to be run in

But the upside, the octane rating is pretty impressive on gas for something so cheap

[na-118]

it doesnt have to be dual fuel,,,

a lot of the retro gas conversions are 100% but that ****s your car up big time,

gas converted cars usually need petrol to start it then the converter kicks in and changes it to gas

the octane rating on gas blows by the time the liquid has been converted to a vapour and traveld to the chamber via a hot plenum. Gas in a liquid state is about 112 octane, you loose alot during atomisation and end up with something like 80-85 octane when its in the chamber. The longer the vapor tube the more octane loss

LPG injected is the way to go. thats when you gain power over petrol. LPG injected has not been radified for comercial use.

overall you can convert your CRV to LPG. and if done corectly you will enjoy many years of happy motoring. If done incorectly you will suffer many years of frustration

I wouldn't do it if I were you. Gas is too expensive for what it is. It was hardly more than 40c/litre when my dad converted his Fairmont about 18-24 months ago, now it's over 60c/litre. I know all fuel is a tax-ripoff but due to the unprecedented rise in gas cost it will take you a long time to recoup your money.

At 40c/litre +/- my dad and I worked out it would take him about 2-3 years to break even on the cost of the conversion.


Sure is cheap though. His Fairmont is cheaper to run than my Civic! He uses about 15L/100km around town so it's costing him hardly more than $9/100km.

[aznstyler]

well im geting about 12L/100k's
i filled up $20 which got me 14.4lt's and i only got 116K's out of it..
the system i was looking at, is dual fuel.
automaicly starts at petrol then switches over to gas.
will it damage the engine?

[dougie_504]

This is what my dad uses. Gas burns hotter than petrol so I believe the converting mechanic has to take this into consideration and change certain parts, but I can't remember what.

Also just need to make sure that occasionally you put in a full tank of petrol and turn the gas off, run it on petrol with some injector cleaner. My dad's car started running terribly when it started on petrol, fluttering and reluctant. This fixed the problem.

no it wont damage the engine.

one of my mates falcon has opposite problems, it starts horrible on gas, stutters than on petrol starts fine, i personally think its better to buy a car thats designed to run on gas, LPG converted cars from what iev seen have always had some sorta problem

[Dash]

Ive seen a toyota hilux 88 hit 400k on duel fuel..94 hilux, toyota said it wouldnt work..still going strong and that got 350k plus... Gas is reliable if fitted correctly.. My crv is shit on fuel... I would be happy to get 100/10ltr but i dont get anywhere near that...

[Dash]

Also when it come to sell a gas car u gotta take it to a guy with RWC LPG gas testing.. Tank cant be 5 or 10 yrs old cant exactly remember how long.. Had to sell the ute and had to hunt down a gas RWC guy...

[stndrd]

in melbourne, vicroads rwc testing laws state that 10years from the date the compliance plate on the tank, your tank has to be ripped out and re-tested. liquid injection is the way to go if you are looking at converting to LPG. the main benifits are that, as the name states, the LPG is in a liquid form right up until it is injected into the manifold. yes gas does burn a bit hotter but gas also loves higher compression ratio's (14.7:1 for petrol vs 15.7:1 for LPG). last time i asked, liquid injection kits start at about $3500 i think (tho i was quoted by one of my trade school teachers who is on the AAFRB panel and is the authorised teacher for the LPG fitters course in melbourne) and that was for my b18c1 set up fitted & tuned. if you are serious and live in melbourne, pm me and i can put you onto the right people to talk to (not your everyday fit a LPG system with no license mechanic)

[dc292177917]

my crx is abt 9L/100km on BP98
85%+ city driving
after seeing the mileage u guys reported
i think B16 is quite fuel efficient lol

[aznstyler]

many people say honda + lpg doesnt work.. just wondering if anyone on here is running a honda with LPG

[ECU-MAN]

honda + poor installation = doesnt work

honda + installer who knows what he is doing = works

same goes with any manufacture

[dougie_504]

For a 4 cylinder car I honestly just don't see why you'd bother...

[stndrd]

cheap way to make more power for less is the reason why i looked into it. tho CAMS doesn't want to know anything about you if your running LPG and plan on doing track days. so E85 is the only other choice (unless you convert to common rail diesel) lmao

[dougie_504]

I don't think gas makes more power than petrol

[stndrd]

before the F6 typhoon was released, FPV did some testing with petrol vs liquid injection LPG and apparently they were seeing up to 15% power gains. everybody needs to get out their head the old vapour systems. this is dark age technology & the liquid injection kits provide a small supercharging effect due to propane having a boiling point of -42degree C. what this means is when the LPG is injected into the manifold, it boils (cold burn) and freezes the intake air, which in turn, makes the air more dense, so you can add more fuel with it due to the extra air that is in the chamber and then more power is made (sorry if i haven't explained very well, flat out at work but just wanted to touch base on how it makes more killer wasps)

[Lukey]

if you want good economy get a small turbo diesel car,

like the i30 or fiesta or whatever it is ford makes.

[dougie_504]

If you want good fuel ecc get a friggin' 3 cylinder Daihatsu Charade for around $800 lol. Runs of fart gas.

I don't really know and I'm not too bothered. But if you want power then don't convert the car to gas for a $2-3g. You modify other things.

[stndrd]

obviously if you are chasing big power gains then you build your motor or turbo/supercharge it. at the end of the day tho, you choose to ignore LPG and stick with petrol, yet with the amount of LPG australia is sitting on (freaking squillions apon squillions of it) and with holden & ford pushing the federal goverment to stop raising the taxes on LPG so they can bring out more cars on dedicated LPG, it's the way of the future mate. and for some people, its not all about killer wasps either, and this is why they go to LPG because they are trying to bring down overall running costs of the vehicle (but a few extra kw is a good by-product)

[aznstyler]

lol i dont want more power, i just wanna run my car cheaper

[Lukey]

buy a i30 turbo diesel

4-4.5lts per 100 (depending how you drive/conditions)

[stndrd]

dont bother trying to tell mr aznstyler to buy diesel. he has had his mind set on crv for toooooooooooooooooo looooooooooooooooooooooong

[Lukey]

and then going and ruining it with gas

[mugen_ctr]

honestly, should just buy a car thats design for fuel saving lol, crv are a family car, not a eco car, diesels are great, despite the price of diesels, the kms they can get, out weighs gas, short an long term
