My Technocarb lpg mixer arrived the other day, nice chunky piece of billet alloy, only seen pictures before I ordered it. If it works as good as it looks it'll be a winner.

Pete , Fill us in on the rest of the motor ? Where did you get the gas mixer ??? That sure looks flash . Is it going to be straight LPG or dual fuel . Lon

Hi Lon, rebuild is taking longer than I had planned, usual problem, no money!! nothing special in the engine, just the usual decking of the block, bigger valves, 4 barrel manifold etc etc. Engine is going to be straight LPG, has Crow lpg cam and will be redoing the dissy curve to suit, The technocarb mixer is sold by Torquegas in Caloundra. how is your F100 progressing?

That is a nice looking piece. I don't know how much experience you have running LPG but I hope you have the right parts in your heads. I work on a lot of LPG engines and they are murder on valves, seats and guides. I'm not against LPG, it's a great fuel, just make sure your motor is built for it.

Tim, Don't no about taxi's in USA,but down here, they all run on LPG . Many of them seem to do a lot of miles ( or kilometers ) 300K miles is not uncommon.A mate of mine a few years ago had a 39 C%$V with a 302 Windsor in it .It ran really big compression and went real hard as well . Lon

Over here I see LPG mostly on farm trucks and water pump engines, all I was saying was that it is hard on the engines not that it didn't run well.

Don't worry every thing is built with lpg in mind, hardened seats, late model valves etc. forgot to mention before, the mixer is the 570 cfm version. A lot of the forum are probably thinking WHY lpg instead of petrol. Running costs are the main reason, at the moment unleaded is $1.25/litre lpg, 47 cents/litre.

Pete , That works out to be about $3.54US per gallon .LPG is about 35 cents ( US) per litre .( Liter ) Exchange rate right now is approx $1 Aussie buys 75 US cents . Lon PS Tim , What's the price of gas ???

We are paying (in my town) $2.55 now and rising for the summer, they like to stick it to us when vacation time comes they tell us in CA that they are reformulating the fuel for less emissions in the summer heat. I'm not sure what LPG is going for the last time I filled my BBQ tank I just traded for a new full one, mine was a little rusty $18 for the five gallon tank. I know it's cheeper to just buy the fuel.

How does LPG compare to gasoline in terms of power and efficiency?

Substantionally less on both counts,depending on engine type and usage.However,the lower cost per gallon and the far less engine wear can make LPG pretty attractive in many applications.We had a neighbor that bought a new 56 Victoria with a 312 that he converted to LP.He drove that car up into the 90's.When he finally parked it the engine had never been opened up and had almost 400,000 miles on it.Many of the farm tractors in our area were LP powered back in the 40's and 50's.

Here in British Columbia, LPG is mostly used by fleets, however the practice used to be to break engines in on gasoline & then convert. That may not be the current situation. Mileage & power is off by 10-15%. I don't have a price per Litre at hand but for Barbecue fuel, the price has nearly doubled in the last 2-3 years. We had 3 light trucks at work on propane & all were trouble prone, particularly in winter. And one unit would not pass emissions tests. It required "special" tuning to pass at least twice.. Taxi companies are going to imports & hybrids, the popularity of propane is likely fading here. Many light trucks are now diesels. Gas is currently over $1.00/ liter or over $3.78/ U.S. Gal. or $4.54/ Gal.! (Imperial)

Many fork lifts are propane powered in this area of the country. Probably because they have a less annoying odor than gasoline trucks when used inside a closed building. Of course, many companies use electric trucks, but they require charging frequently.

Our lift trucks had water heated mixers, so no problem in winter. They ran mostly inside, but sometimes were taken outside in winter.

Reformulated my azz, basically all they do is blend with less lighter ends (pentenes, a by product) in the gasoline so it doesn't evaporate in the heat as fast. Which equates to blending heavier components (more expensive) to make a gallon of gas.
Of course I way over simplified the process but I'm sure you get my drift. I worked in the Alkylation Section for over twenty five years in the largest Refinery on the west coast, Chevron El Segundo.

What you just said sounds like a reformulation of sorts to me, what term would you use? Morehevieracation.

What I said wasn't a dig on you, Tim. I meant as the Oil Companies make a big deal out of "reformulating" gas for summer months and all we do is put more heat in our Debutanizer to fire more pentenes overhead so it doesn't go out the bottom with the gasoline. Thats how we control the vapor pressure of the gasoline for summer and winter months. You can use a play on words all you want. Yes I guess you could call that "a reformulation of sorts to me". But the Oil Companies are charging you for it.
But as long as you asked I would call Reformulating gasoline adding something to the the basic gasoline "forumla" such as an oxygenate (methyl tertiary butyl ether or MTBE comes to mind, mandated by our great state to help air pollution but ended up polluting the ground water. As a fellow Californian, I'm sure you remember that) that changes the basic gasoline "formula". And yes it is Heavier or as YOU call it "Moreheavieracation" (I took the liberty to correct your spelling).
Speaking of MTBE, Chevron El Segundo had to build a whole new plant to make MTBE so it could be ADDED to our gasoline to satisfy California's CARB Emission Standards. That Plant is now sitting idle after it was discovered MTBE was polluting our ground water. And Tim, who do you think got to pay for that...
And with that, I'm done... See ya

Johnson, Maybe you don't need it, but WE do. Tim and you agree the whole thing's a crock. He didn't mean to offend you and we sure as hell need to learn about reformulted Gasoline. Evidently C.A.R.B. does also. My organic chemistry is 40 odd years old, so I can just barely follow you. Can you phrase it for others without the chem classes to comprehend?

Frank is right I did not mean to offend, and I too would like to know more about the fuels we use. It is hard to see or hear a persons expression in type so don't take things I say so harsh, I just have a sense of humor. If Johnson comes back maybe he can tell us more about the MTBE as I recall it was to help lower carbon emissions some 10% but you get worse gas milage and burn about 15% more fuel, not to mention polluting the ground water. By the way I talked to my cousin that buys LPG 500 gal. at a time and he said last time he paid $1.75 a gal.
