LPG

Postby AustinR » Fri Nov 23, 2012 7:20 pm

Anybody ever look into/actually accomplish converting a vehicle to run on LPG (Liquified Propane Gas)? I started looking into it the past couple of days. Looks like it's cheap to run a car on it (cheaper than gasoline). I'm having trouble finding information on exactly what you need to do to set it up, and if it effects performance. Looks like you can get more BTU's out of propane, but I don't know if that means more power/less power or what.

I've never seen an e30 converted but I've seen some older cars converted. It was pretty neat but I really don't know what all is needed.

From what I can find, like half the price.

Go search around e30zone.net, LPG and CNG are much more common over there and I've seen a couple builds there for it. Initial cost to convert is pretty high, so you would need to do quite a bit of driving to get a return on investment. There is also not much of a LPG infrastructure here in the US, so you would be pretty limited in range unless you plan on carrying a transfer setup so you can buy the grill type canisters and use that to fill your main tank, which wouldn't get you too far anyway. I'm fairly sure you need a tunable ECU also, or at least the ability to tune Motronic for the new fuel type, not to mention MAJOR engine and fuel delivery modifications. You would probably be better off converting to run on ethanol, but even then depending on your location finding stations that sell it can be difficult.

There's an LPG place within two miles of my house. IIRC, it would still take A LOT of driving to offset the cost/effort/maintenance of the necessary setup. Biodiesel or ethanol seem to be more practical alternatives.
