personal opinion? i would never own a falcon that wasnt on gas
if i wanted to do ~15L/100klms of petrol i'd get a holden V8

Got a Parnell VSI system fitted to my BF XR6 ute, found the installation to be well done, the utes gone hard on gas from the day it was fitted, everyone who drives it cant tell the difference between both fuels. I reckon it actually goes harder on LPG than Petrol. I Enquired about the sprintgas system myself and was told the system was unrealible, something about injectors being dodgy.

Two thumbs up to LPG on Fords :hihi:

the injectors and software were updated early this year on the sprintgas resolving all the issues . i had to wait for mine till the finished testing of the new system and the results are excelent . after how a forum member was treated by parnell i wouldn't trust them with a roller skate

Yeah, I read Schmidty's thread, my experience was the exact opposite. Wrapped with the way the ute performs.

You don't have shares in Sprintgas do you?

God i wish he did... just so i could get a good discount

PoweredByCNG · 18-03-2008, 06:54 PM

The OMVL Dream XXI (Sprintgas) system is excellent, cannot fault it myself. Some people have had problems with the old injectors in the past, but the new Keihin injectors seemed to have changed this.

Go dedicated GAS amisupposed2b.

A mate of mine has done it to his XF. Among others things, he removed the petrol tank completely and put the LPG tank in its place, and hello boot space... Being a grease monkey himself, kinda helped I suppose.

He says itll run 14-15sec on the 1/4mile, never seem him run personally, but i'd almost believe it given the way it drives on the street.

Anyway, dedcated gas IMO. Itll take some work (and $$$), but has its benefits.

you can only do a mixerring system on dedicated gas AFAIK and a mixer ring is always going to be inferior to an injected system and no NICEBFUTE I don't have shares but have had 3 sprintgas systems including this SVI and they have all been excelent and my current SVI was better than expected

I can't think of any reason why you couldn't have a dedicated SVI gas system, what would be the issues in doing this?

The SVI ECU needs a petrol ECU to calculate injection timings. SVI systems also start the car on petrol to preserve the starter motor of all things and also to help with lubrication and to prevent engine wear, not to mention preventing freezing of the regulator.

XF's were available with the EFI option.

I personally don't think it's a valid comparison - a petrol AU vs a high km LPG ex-taxi. The taxi will more than likely be a little slower than an equivalent non-taxi simply from being half (or totally!) clapped.

If the car is an E-Gas model, sell it and buy a petrol Falcon. There is alot missing from the E-Gas model, and to convert it to petrol would simply be a waste IMO.

If it's an aftermarket dual fuel setup, why not fix the petrol system as JC suggested?

Apart from all of the above, I think the price quoted is a little expensive given they'll be keeping your LPG setup which they'll on-sell.

you don't have to have petrol start, i know someone who has got a vy gen 3 ute, straight lpg parnell system, has the car computer to run the accessories, etc but no petrol whatsoever, has replaced the petrol injectors with gas ones and also has twin turbos too, mind you he fits a lot of parnell gear aswell, and as with all systems, there is nothing wrong with them, 9/10 times it's the installer/tuner problem that the cars don't run right

oh and as to the post before about the injectors, they are now made by aeb, not keihin or whoever they are

oh, and also to add, there's no reason why the sprint gas system couldn't be set up to run straight lpg either, you can change settings in the software as to changeover temp and changeover delay, etc, so set this at a low enough temp and there's no reason you couldn't run straight gas, especially with the new injectors......i may just have to try this out....

I didn't say you needed petrol for starting, I said that starting on petrol reduces the chances of any problems occuring (e.g. excessive starter motor wear and regulator freezing).

But I thought you could get Keihin injectors for Sprintgas kits?

Are you sure? I'm pretty sure that the OMVL system requires information from the petrol ECU in order to calculate injection timings.

bodes-sh · 18-03-2008, 09:07 PM

yeah, it does, but it doesn't mean you necessarily have to have petrol injectors in the car, as long as the car ecu and wiring are there....i'll give it a go tomorrow and see what happens, i work at sprint gas so it's not like i can't easily try it...as for the injectors, you may be able to, but the software is set up for aeb injectors

TURBOTAXI · 18-03-2008, 10:03 PM

Keep the LPG in case that was not clear.

Also - $800 installed is about $400 too much regardless of
lpg system.

I have dedicated lpg svi on my v8 and the guys who fitted it have done plenty of others - new cars and old cars - I'm impressed with the way it runs. currently 215rwhp, but going in next week for a stroker rebuild and new heads and hoping for somewhere around 300rwhp.
but that being said, in most cases I'd reckon you may as well stick with dual fuel - gives a bit more convenience as not all towns have lpg if you decide to go for a trip, petrol is still going to make slightly more power (or at least has the potential to) - don't believe anyone who says otherwise. you could keep dual fuel, get an edit / custom tune for petrol, and just use lpg for economical cruising... just an idea

bodes-sh · 20-03-2008, 07:57 PM

ok, finally got time to test some things out....with the new sprint gas software you have the option of normal petrol start, gas start or straight lpg, but the system still requires a petrol ecu to get injection timings from, the pic below shows the different options

it's fairly easy to set up and works pretty well for the little play i had with it...

sly · 20-03-2008, 09:24 PM

I'm surprised no-one has suggested the OP get an edit with custom tune to optimise the timing for LPG...

If his system is Impco it should be less restrictive than a stove ring?

Cheers

An SVI system would be fine with that. To be on the safe side, discuss your plans with the installer. The SVI system I just had put on my wife's AU3 wagon is the same as used on the Territory Turbo... plenty of spare injector capacity!

is that the same as mine ? the new sprintgas?

That's as of about 6 weeks ago... not really "just" done.
