About $500 for everything..... What do you think? Canadian supplier in BC

I read Lance's report..

http://www.pirate4x4.com/tech/propane/index.html

Read everything on the lists that I could find about it.

Not a whole lot more money than a TBI system or other FI...

Not something I am going to do this month, but maybe in a month or two?

Pretty high coolness factor...

No more carb splash. Runs at almost any angle. Cleaner exhaust. Easier on engine. No fuel spills.

A little less power.... Harder to find a shop to tune it...

Yeah, I picked up the whole setup and thought about running it..but...those fawken tanks get in the way of everything....:mad:

So, what did it cost you, and what did you end up doing with it?

What are the chances of finding a tank, or multiple tanks that will fit where my 33 gallon are now? Just build a very stout skid plate to go over it?

Jim at Anything Scout had a propane powered Scout II. The tanks where in place of the factory gas tank, but hung too far down to be used off-road.

Give him a call I wouldn't be surprised if he still has the kit and would make you a deal on it.

We have lots of propane here.I've got a 90litre tank in the van.There are tons of different sizes,I've seen a two tank set-up that replaces the gas tank in a ford pickup,should be about what you need.Try phoning around Vancouver with some measurments.
500$Can. is about what they go for a complete used system(425) here.

Thanks for the info. I contacted *the propane guy* and am waiting for answers. I really need to take measurements on my tank, and the area around it so I can see what tanks are around and what would fit.

$400 canadian is less than tpg was offering. His setup was around $800 canadian or so.

I guess it comes down to, can't see why I should spend $400 on TBI or FI when I can go to propane with the additional advantages. I think if I can solve the tank location issue, I will go this direction. If I need to/want to, at some later date I can get my heads shaved to bump up compression.

You have to (in most cases) pull the manifold to change gaskets, so you should just go the full nine on the heads while your in there

Mill your heads down big time (if not allrady been done) then no more power loss, ya got the valvs for it anyway

propane hear is dam cheap .33 a leater thats about .16 you you guys :eek:

That is a new one on me. So, I have to yank my intake manifold to change out a gasket for the conversion? Mixer gasket or??

Fuel savings is another issue, but not one I am counting on. Decrease in mpg kind of balances lower fuel costs, I think

I've thought about going propane too. I think I would use some Forklift removable propane bottles, get 2 or 3 of them. From what I've read the biggest expense in the conversion is the tank, and the Forklift bottles should be relatively easy to find used. Try a heavy truck & equipment wrecking yard and see what used tanks they have.

You'll want the "LPG" intake gaskets.. that no longer circulate hot exhaust under the intake to help fuel atomization.. since you're already pumping a gas in. ;)

What are all of these "advantages" of LPG you're talking about, Pat? Aside from not having to pony up for the fuelie kit..

Is it "fuel is more readily available at every gas station in the country"?

Or is it the "less power" feature?

Or are you hoping since it burns cleaner to extend the life of your rig?

33 Canadian pennies per Liter.. what's it all work out to in the end though.

$/mile gas vs. $/mile propane?

And how far could I go on my 100lbs Propane tank? It'll heat my shop up nice n' toasty warm for a lot of hours (haven't refilled the tank yet..).. for $30. :D

Advantages over carb, or advantages over FI?

Not many advantages over FI. Lots of advantages over Carb.

Biggest advantage over FI is the propane pulls from the bottom of the tank, so you can stand it on end, even with a half full tank, and still draw propane.

Burns cleaner, friendlier exhaust and less carbon through the engine.

Not too worried about availability. It is unusual to see a gas station around here without propane.

Running propane cost is a wash. A little cheaper per gallon, but lower mpg. Range is probably down a little from my 33 gallon tank, but not too much.

It is a simpler system. No FI computers to worry about diailing in, glitching, burning up, etc.

There is an interesting idea. Run different size tanks. For long wheeling runs, throw in an extra bottle. For around town, run a small bottle. Wonder how far I can drive on a BBQ size tank? ;)

Not too happy about taking up space in my bed with propane bottles though. That is the biggest downside, to me.

\Biggest single expense is the tank. About half the total cost, from what I understand.

ok..back from a meeting...

Well, My propane set up is in the for sale section...although, I haven't been pimpin' it lately so it's probably a few pages back...I bought it for umm....next to nothing on a spur of the moment thing because I knew that I could always sell it to make some decent cash...we were going to use it to run on a competition vehicle..but when, I have no idea..I figured that if it sells, then I will buy another set up if I need to..if it doesn't, then no biggy. I asked Jimmy (The Jerk) what he paid for his and I beleve he said $400 w/o the tanks...so that's where my sale price came from...

As for changing out the intake gaskets...I would recommend it..but you don't have too...I wasn't going to on my current Piece of motor...

BTW, I'd rather run LPG than FI due to the ability to fix it out on the trail..I am anti-computer anything for a trail vehicle...too much to go wrong.

As for smaller tanks..I've seen companies that sell doughnut shaped cylinders...easier to fit under the vehicle..but they were around $400 each:eek: ...


Anyway..hope that helps...

Thanks for the info.

Just read this article
http://edge.edge.net/~deschamp/tbitech.html on TBI. $1100 ????


Ouch. Is that what FI runs for an IH? Propane is a LOT cheaper than that.

I'll go check the FS section

Thanks

Your only going to loose mileage if you don't do anything about the compression.Bring it up to 10.5-11 to 1 and you're going to get the same mileage as gas.
Propane here is about half the cost of gas.I save just about 1/3 of the money by using propane compared to gas in the van and the motor had no work done to it.It would probably be half if the compression was higher.

I'm planning on using the van system on a 345 I have for the scout eventually.

If you do it make sure you have a way to use a BBQ tank because running out of propane is way $hitty:(

thats why I'm going propane, its simple and less sheit to go wrong,plus I got my setup for free just have to get fork lift tanks and I'm set:D

I really like the simplicity aspect of it. After watching a few folks fight fuel injection.... simple propane sure sounds nice!!

Free is always good. Where is this shop that I can get stuff for free at? Ever find propane stuff at junkyards? Should I call a forklift repair place and ask them for good quality used stuff?

Where are you going to mount your tanks? Concerned about taking up cargo space in the bed?

They sell a hose that adapts from bbq can to engine style. $40 or something like that. Then if I get low, I just swing by lowes or home depot or fredmeyer for a refill ;)

Did you notice much power difference? Did you replace your intake manifold gasket?

R O
07-12-2002, 10:57 PM
I know about the adapter now:) .
I bought the van because of the propane,it's cheaper for work.I really don't notice any loss of power but the motor is bagged sooo.

Propane gets a bad rep about the whole power deal.If you build the motor for it you will not loose power,higher octane than gas.

I don't know anything about different gaskets,I didn't build the motor.I will ask a friend that built a 460 for propane what he did.

Hoop, thought about running a duel fuel gas/LPG setup??? you used to be able to find them on old railroad pickups and what not.

run on anything, get a MSD timing control box to take care of the spark issues...

Anyone ever notice how similer the build specs are for a LPG motor and a E-85 motor???

I want simple, and no computer, thank you. That is what appeals to me about the propane over gas. Much, much simpler system, with many fewer things to go wrong, and the components in it are not at all fragile.....

07-15-2002, 07:51 PM
the box i was talking about is just to adjust the timing retard, so you have mo' power on either fuel. You could install it to be easily bypassed if it went tits up.

On the power issue, my friend converted the 350 in his Suburban to propane, then turbocharged it. I believe the static compression ratio is around 9.5, but under 4 or 5 psi boost it pulls pretty damn hard, much better than a 350 ought to in that situation. He also has water injection on it, which cools the intake charge substantially and increases power very noticeably.

Just another thought. The turbo works well with propane because as we all know, propane is more resistant to detonation and preignition than is gasoline, and will put up with much higher compression ratios (combustion chamber temperatures).

in case your wondering the propane systems came off the old mans crew cab when he sold it,thats why it was free, the propane tanks off fork lifts are the ones I'm going with, easy to mount, built in fuel gauge. I'm mounting mine behind rear seat, solid to cage, off floor, and yes I see them in junk yards all the time, always vans
