mini wiz bangers

I don't know for sure if any fitters are doing small wiz bangers for LPG conversion: most are simply run off their feet doing large diesels.
As far as taking up boot space I see no more of a problem than the Ewe -beaut hybrid electric cars we have to have now - with a boot full of deadly corrosive, heavy, pollutant batteries? As I said - the LPG cylinder is very small and in fact a clever installer could use 2x smaller cylinders which could be fitted up against a wheel arch or some place. The 2x cylinders combine could make say 25 litres of LPG; which would be enough for most small cars.

It all sounds great but all the vehicles that are shown or mentioned in the applications are either 4wd or trucks like (F100 / F250) so there is plenty of clearance underneath for a gas cylinder. If you can show me an application on a Golf or Polo where it doesn't take up half the boot or reduce the under carriage clearance then I would probably consider it in the future. I am not into 12 inch sub woofers and other fully sick devices in the boot, so that's not part of the equation, but I do need the boot space I have and wouldn't be prepared to sacrifice it with a permanently fixed gas cylinder regardless of the obvious benefits. Excellent idea though but perhaps not for the small diesel cars, unless you don't require any boot space.

For those who don't need the boot space (yours truly), its a great thing. If I end up modifying the Polo TDI instead of replacing it with a proper sports car, I'll probably go for LPG-Diesel. Don't care if it takes up the entire boot, I can count on one hand how many times I've used my boot to carry something bigger then a single, small shopping bag in the last 3 years on one hand.

Well said Pumpe,
It amazes me how people moan about boot space - but in reality most dont use the boot..most are just kid fetchers and glorified taxis.
Even making a false floor across the base, using a sheet of plywood (made in Australia of course), would solve most issues?
I see no arguement why any one couldnt have it done on any car - it can and is being done on stationary Diesel motors, trucks, & buses, so what makes little buzz boxes any different?

Having an opinion is one thing moaning is something entirely different. I agree that it is a great idea (gas conversion) and if I didn't require my boot space (which I do use on a daily basis) it probably wouldn't bother me having a gas cylinder in there. Maybe down the track I may consider it but in the meantime it's just not practical for myself and probably many others so rather than calling people moaners why not keep comments like that to yourself and just stick to the topic !!!

If youre that passionate about every diesel owner installing LPG then Im sure you've got your 911 booked in for a gas conversion too.
After all, petrol engines can run on gas too and im sure you can find somewhere for the gas tank so why wouldnt you.!

settle down fella's its all in the name of economy. play nice.

[Greg Roles]

I've been looking at powerups and think it's the way to go. I don't give a rats about economy, I want the herbs! Economy is an added bonus. One of those cool small donut tanks in the spare wheel well, or a small tank in the place of that ludicrously large rear muff on the Golf is the berries. That way I can keep my fully sick sub and amp setup I'm about to install, and keep the stock boot. Best of everything! Add to that my brother is planning on getting his installers licence adds to the appeal....

The concept of complete combustion, and little soot is awesome, as it may allow removal of the DPF without adding to the pollution or visible emissions I have to breathe in when I cycle. That then frees up the exhaust restriction, for yet more imprezza slaying torque.

Shyte, if you could add Nitrous at low revs and get power, I'd have already ordered a kit, regardless of it's legallity....

I'm just in awe of how great the stock car is, and my long term plan is to convert it to bio, and have an additional "on demand" LPG system. I'm playing with the thing in the meantime within reason, with the aim of setting up the engine for this longer term plan. Overdue on a few projects at the moment actually!

THEN...I can chip it...

I have already looked at converting the Porsche.
Two problems exsit;
1/ Location of gas cylinder
2/ Using hot engine oil to heat the converter - water pumpers use coolant to heat the liquid LPG, converting it to gas. I have yet to see if anyone makes or uses a converter using oil?
Cogdoc,
You sound pretty keen ... your would make a good project to cover here?
Good for you.
Years ago, my FJ60 (landcruiser), I did an engine swap; removed the hopeless Toytota 6 and fitted a 350 V8 Chevy. I then ran this on LPG wholly, no petrol. Oh what a feeling -- Chevy. What a buzz that was!
Such a transformation.

I did the same with a VK Calais i had years ago, ran the 308 on straight gas with a Gas Research system, I had the heads done and a gas cam in it and it was sweet.

anything illegal about setting it up yourself? the hardest part would surely be figuring out the filling system right?

im not sure legalities, but insurance may have something to do with it?!

i like the idea of more power, i love my TDI and anything that gives it even more oomph and economy is a winner for me

Good Question gld,
Here in the land of Oz - no we cant do it our selves, has to be installed by a licenced auto spanner. The vehicle must then be stamped with what amounts to a compliance plate. The cylinder also needs to be inspected every few years - cant remember how often.
I know in England you can fit a full system complete - odd; as I use to think when I lived in UK that England was a "Nanny State".. I am wondering about here now????
The Diesel conversion- depending on the system you use - is actually easier to install than a petrol/LPG system. Because, some of the diesel conversions use just the gas coming off out of the LPG cylinder to inject into the motor - which shows just how little gas these systems use - almost nothing.
Whereas a petrol/LPG uses a large volume of LPG and so needs to heat the liquid LPG to quickly convert it back to a gas.
So this means some of the Diesel conversions have very few parts.
One such typical system is here
A more elaborate conversion using sequential injection system can be found here
It is this system that I would prefer myself; more expensive but has a lot more features, ie; use the brake or off the gas pedal and the LPG is switched off.
Doesn't sound much but it means your gas supply is extended further, making your range even greater. This system also uses LPG at idle; making the idle smoother and transition from standing start better. And there are more features, etc, etc. But this system uses a converter (heater) to heat the liquid LPG.

I have requested info from ....

Here are the details submitted by the website user:
Name: Steve
Vehicle: 2007 Golf 2.0l TDI
Email:
State: NSW
Comments: Can conversions be done to a Golf? Does installation impact on manufacturer's warranty?
Where would the gas bottle go in a Golf?
Cost for a Golf?

Lets see what happens.

Well they are not very good at selling their products....

Pricing starts from $4500 inc GST. We can fit a tank under the rear (but I
think we need to mod the exhaust).

I do not know VW's warranty policy.

If diesel gas is easier to install they are just ripping us off at $4500

Since the government started offering the $2000 rebate the installers have been charging an extra $1000 - $2000 for an installation.

As I have already tried to explain there are what amounts to, two diffferent gas systems for the Diesel; one uses pressure feedback from the inlet manifold while the other systems use a more complicated system using a ECU to control the gas.
It is the second system that Spoddy has asked for a quote for.
Also as I have said before, these guys are run off their feet and the fact that you even got a reply at all surprises me.
The cheaper system ( the pressure sensor one) goes for around $3800.00 less rebate.
