Quick Question

[Phoenix21]

hey all just two quick questions i need get the water pump changed in my vn has any 1 got an idea how much that will cost and another thing i wanna get gas put in my car has any 1 done that recently so i can get a price off ya thankz Phoenix21

water pump will be cheap. changing to gas can be betweeb 1500 bucks to 2500 bucks. advantage, cheaper to run, disadvantage, expensive to convert and doesnt run as well, like doesnt have as much grunt.

[Doctor Sodways]

Gas can produce more grunt from a car but it needs to be tuned to run on it, and then you have to run on it basically all the time and use petrol for emergencies or long trips, another down side is the cost to convert it, its a huge cost to begin with, and to save the money you spent will take longer than you imagin.

My old man runs his car on gas, a 98 jackaroo, and it produces more power on gas, but its only on gas due to the fact he bought it new, so it dad save him cash, you really need to think about whether or not you do the kays to actually save what you had to outlay first, which is why my car isnt on gas

[mouce]

Also, generally the cost of servicing a car on gas is higher than just straight petrol, for the simple fact that gas runs hotter and is a lot drier than ulp. This places extra stress on the entire cooling system and a few other bits and pieces.

yer i spose it just the fact that buy the time im 18 i doupt i'll be able to pay for petrol all the time it just getting to expensive

[fitzy2005]

havent u seen the increase in gas since mid last year, its goin up as well, will gas really benifit you in long run..

[mouce]

Also, if you ever travel away from major metro centres LPG can be hard to track down. I've heard that it's almost impossible to find in Tassie. I know someone who paid 80cpl for LPG in Tas.

Another thing to think about is the distance that you do, for a gas conversion to break even you need to do more than 25,000km in a year. And that distance is going up all the time. I actually looked at doing a Gas conversion on my VN exec, and I just couldn't justify it.

[Doctor Sodways]

Thats the problem people have in trying to justify a gas conversion, can you do the kays required for it to actually cover the cost of the conversion and start to save you money in a short period of time, sure, in maybe 10 years or something, but will you have the car then? One of the other guys on this forum gets about 400-500 kays on a tank of gas, but bought his VN that way, so he saves straight away, but converting it it would be a different story

was speaking to my dads mate recently, he makes heads for a living, (everything from tuned heads to customised standard ones)

he was telling me the average life span of a head on gass is SIGNIFIANTLY less than that of a unleaded car, for such reasons as mouce pointed out, the excess heat... the principle being, make sure you change your coolant regularly on gas...

true a tuned gas setup can be powerful but the same can be said for a tuned unleaded setup... most cars are undertuned for better economy,

my opinion is... if your car didnt come with gas... dont put it in...
but who ever listens to me =D

well thats my 2c

Bah, you'll always get people with different opinions on how gas goes on a car. I learned to drive on an LPG powered XC falcon, first car was an LPG XE, Dad's work ute is an LPG AU. Guess what the only thing to never cause a problem on any of these cars was? XC and the XE both went for 200 thousand K's plus on gas without any valvetrain/head problems. AU has just clocked over 120 thousand on LPG without any LPG related problems. look at taxis FFS! Do ya think any of that lot could be stuffed replacing a head or even valve seats? Most of the bloody things do over half a million kays in their lifespan, I have only heard of isolated incidents of LPG related problems. Yes it provides poor lubrication for inlet valves, no it doesn't cause many problems over the normal lifespan of a vehicle.

That said, it's probably not a financially viable conversion to be doing at the moment. The excise is coming in in 2008 or 2011 to bring it in line with the comparative cost of petrol. The price is going up anyway for various reasons, besides which I love the smell of unburnt fuel as I start my car up in the morning and it's running rich in closed loop with that absolutely sexy burble and....... hmmm, right where was I? ahhh yeah, stick with the petrol bro, expensive but trouble free (relatively anyway), enjoyable and oh so horribly capitalist of us! If however you got your hands on a cheap as shite dedicated LPG vehicle then it might be worthwhile.

true, my uncle was a taxi driver, he had a AU, he clocked 1,000,000km on it, never replaced the injectors, and never cracked a head (by 1 min it had oil leaking out of everywhere)

the point is, keep your car serviced / regularly checked and it wont screw up, (he also used injector cleaner every 3 tanks...)

[mouce]

^^^maybe I'm missing something, but if it's running gas then why would the injectors have any problems?

Doesnt sound like it ran on gas to me. They dont use injectors mate

Hehe sounds like how mines tuned, pretty much just for gas, and when i need to tuned for petrol, and i only use 98RON with octane booste, otherwise it's sluggish.
