It'll be a fun thread on pistonheads, and a lot of "just wrong" will be spouted :pac: But at the end of the day, it's just an alternative fuel, doesn't harm the car, so why not capitalise on it.0 -

As long as it didn't affect the V10 bawl, I'd be willing to live with the trade off of starting the car like a super-ser.

Hmm, not convinced by the whole LPG thing, more like RPG...

..........Breaking News...........well, after much prevarication, my brother has sent his 3.0t Petrol Saab into Cork for conversion today, so we'll all have another channel of good info on it by tomorrow.
His car is a 3 litre V6 petrol Turbo, so the Lexus answers the normally aspirated queries, and we'll have a LPT turbo application to review shortly as well.
More, as they say, as it comes to hand.....
Oh, and conzy/Matt - if it works out, he might convert his SO's 323Ci as well.Ode To The Motorist

Historically it was associated with large, high power/torque engines as:
- Motor tax based on CC is a local problem so not really a concern elsewhere. Even hear, yearly fuel costs have now (usually vastly) exceeded yearly tax.
- Earlier LPG tech had a notable power hit, which was largely absorbed in big engines.
- NA V8s are comparatively simpler in design, greater in reliability and cheaper to produce than small CC high boost engines, making them better donor candidates.
- Financially the most gain is had when applied to vehicle with the lowest economy, cost to repay installation is much faster on low MPG vehicles.
- V8s sound nicer...
But yes, you could put it on anything and its high octane matches turbo applications well, I suspect an Audi 1.8T with a big turbo installed but otherwise fairly stock is good for 300bhp on LPG while retaining most of its naturally good MPG and low tax.0 -

Update on brothers Saab: I got the date wrong, it's next Friday it's being done............

Update on brothers Saab: I got the date wrong, it's next Friday it's being done............
...sorry it's been so long, but The Brother :rolleyes: is not exactly boards.ie-literate..... :P
So, he's been driving it for a week now, and first thoughts are..:- No performance deficit at all. He actually said it was better, but I'm going to put that down to some sort of psychological inverted buyer's remorse....
- In v.cold temps, it def prefers starting on petrol, and switches over once temps are up
- He's also twigged that running on petrol for a minute before you shut it off (say last spin of the day), makes starting more instantaneous in the following (cold) a.m.....
- ....no difference at all in throttle response
- And here's the science bit: on petrol, the car was returning 27mpg. Gas consumption on a fill-fill basis has come in at....23.5mpg. That's a 13% drop. As a reminder: this a 3.0 V6 petrol turbo (LPT). That, imho, is the economy most people get from their 2.0 cars...
- Here's the wallet-friendly bit: LPG cost him 89c/litre in Cork vs 1.56 for petrol. That's a 43% reduction in the cost of fuel
Ergo, the conversion so far has proven more-than-worthwhile. At his mileage use, the conversion will be paid for in 6 months.
He has to bring it back at 1000kms for a check-over and trimming of settings etc, so I hope to have an update a bit further along. I also want to get to drive the thing.
Seems to me that for anyone where the tax-trap is a killer (aka, luxobarges), LPG is a no-brainer.Ode To The Motorist

@OP,
Just a question on your filling point.
If you fit the protective plastic dust/water cap, can you close the fuel flap?
On this PDF (Pages 36-38), it lists their recommendations of the positioning of that filling point and the use of the protective cap.
http://www.tomasetto.com/downloadDoc.asp?f=all%5F11%5F1%5FInstallation+Manual+for+AT02+multivalves%2Epdf&id=11&r=2
Actually that PDF is a full instruction book on installing a LPG tank and multivalve. It also explains extremely well the full list of safety features that these multi-valves have. Its well worth a read.
I am currently installing an LPG system into my 98 GS300 so I'm sure the existing petrol filling system is very similar to yours, but the fuel flap would not close if I had the protective cap on where you mounted yours so I'm mounting the filling point onto some 4mm steel.

That looks shocking a real botch job. Will you be able to turn the petrol filler cap when the gas pipe and fitting are in place?@OP,

That is only a test fit for the support for the filling point (note: no bolts), its much much stronger than mounting it onto the cars thin-ish panels to support the weight of the LPG nozzle/hose, you have to let the LPG pumps nozzle/hose dangle out of the car when you are filling.
I need to dig out a picture of the the finished filling point, much, much nicer and you dont see any of that support bracket.
And yes, its you can fill either petrol or LPG perfectly, and it closes just fine with the dust-cap on too!
Edit; Found a picture with the filling adapter already screwed it.

It looks very nice indeed. Certainly easier than the old days with the filler hanging from a bracket under the bumper!!0 -

Myself and my father dabbled with lpg in the late 80's early 90's when it was half the price of petrol. We found it easier to convert the figures to miles per pound rather than mpg. My father had a Renault 18 1.4 TL that had a kit already installed but it wasn't running on the lpg properly. A saturday afternoon replacing all the rotten and perished rubber hoses soon had it running like a top. It ran on gas all year round,never needed to be switched to petrol for starting. There was a noticable drop in power between both fuels being the lowly 1.4. On petrol it was getting 10 miles per pound and getting 15 miles per pound on lpg on town driving. I converted a MK2 Cortina 1300,it was giving 8 miles per pound on petrol and 13 per pound on lpg. Maybe the posters here could give us some miles per pound figures from the two fuels.
An old 18 with a 1.4, times have certainly changed since then. you must be a late 60's child 0
