SV6 on Injected Gas now

[redsv6]

The vz sv6 has been converted to prins gas injection so far very happy feels no different in power maybe a bit more torque and bit more quite on cruise and on with foot to floor doesnt sound as thrashy. Anyone else had convertion yet????

[dagar187]

torque has gone up!!?? u havnt noticed any loss of power at all? i wonder wat the other sv6 drivers will think of this. actually meant this comment in a positive way as in other sv6 owners mite want to do the same if u dont lose powerDid you get that help from the govt to do it? apparently they put in a grand or so for the conversion.

[Mackurbation]

I would of thought the power would of went up man, since it is gas INJECTION we are talking about.

[dagar187]

yep.my bad.

Well done redsv6.

I've been doing a heap of research and I'll probably get my SV6 done also with the Prins set-up.

I'm not an expert but torque increases as a result of the higher octane % in LPG. With the old LPG conversion YES, you did lose power but these new Injected gas systems (Sequential Vapour Injection) use their own fuel injection system and power increases as a result. You probably find you gained a couple of rwkw's after the conversion.

Any chance of some pics??

In WA the State and Federal Govt put $3000 combined towards your conversion.

top stuff

whats your economy like compared to petrol?

[redsv6]

Got 450 out of 61 ltrs cost a total of whole $31 woohoo. The whole system cost close enough to $4000 but ya get $2000 back from gov so not so bad.

Gidday RedSV6,
Great to hear about the LPG conversion.

Holden mention in the user manual about not using the 190 alloytech with LPG applications, does injected gas apply differently, or if not, what did you do to get around whatever problem Holden has with using LPG on the 190?

Thanks,
Si

SS,

From looking into LPG conversions myself for my alloytec190 I'm led to believe the 'possible' problems are the cylinder heads and valves failing due to the increases combustion temps of LPG.

The way around it is to get a upper lube kit/flash kit installed when you have the conversion done.

I know people that have done 50,000kms+ on SVI without a drama.

I'm a little sceptical about some of the claims in the Owners manual about LPG. I get the impression Holden just doesn't want you to run your engine on anything other than petrol.

Some places actually offer a engine components warranty, which you can buy if in doubt.

[twb1979]

My owners manual only states that "engine is not designed to run on LPG and performance and safety will be jeopardized"..

Pretty ambiguous statement about the safety considering how many tests have been undertaken to prove that LPG is equal too if not safer than petrol.

My book is dated Nov 2004, well before the Sequential Vapour Injection came out onto the market.

SVI systems can't back-fire either.

Had a couple of quotes myself in Sydney, around the $4200 mark, plus we get the gov grant of $2000. Still debating whether to install it or not, I know the new SVI wouldn't be a problem. Only thing is I don't travel that much (about 15000km/year) and not sure how many years to re-coup the deficit of $2200.

Anyone know whether installing LPG will void the 3 yr warranty?

I doubt LPG is worth it... at ~80 cents a litre now, its just getting too expensive.. Alot of people say petrol is sky rocketing, but its even worse for gas. When LPG first came out, it was often under 1/4 the price of fuel... Then for a long time it sat between 1/3 and 1/2 the price of fuel but now it seems consistantly above 1/2 the price of fuel and theres no doubt it will follow the price of fuel from here, with the gas excise set to bring it even closer to actual price of unleaded.

Say an average of 12L per 100km @ 1.37 (todays price) = $16.44 per 100km... Multiply that by 150 to get 15,000km's (1 years travel for you) = $2466

Now LPG is sitting at 79.9 at say a mileage of 15L per 100km = $11.99 per 100km... Multiply that by 150 also = $1797.... $2466 - $1797 = $669... So basically you are looking at 3 years and 4 months minimum before you break even in terms of fuel costs.

But you also have higher maintenance costs etc. as well... Plus the 12 cent per litre gas excise. Maintenance costs are the major factor because they can accumulate quite quickly. So really will you still be keeping the vehicle in 4 years time? If so, it may be worth it (depending on what happens with gas prices). If not, its not worth it.

better yet just buy a car with the conversion already done..that way youre saving from day 1
