Propane Injection - pluses and minuses...

Hey guys,
Just kinda curious about this. I don't believe I would do this for some time - if at all, but it kinda interests me.
My old "8" is kinda lazy on hills and I thought this might be something to look into in the future. I was curious of what it would cost to do such a thing (parts), if I could do it, and what sort of performance a person could expect.
Oh, and is there any extra wear or trouble I could have with my "mill" by using it. And would it aid in starting when cold.
Thanx,
Chaz

Hi Chaz,
I think there was a discussion on this a couple years ago on the old board.
I remember something about the water content on LP was harmful to the pistons?? ??
I'm sure someone else will remember better then me...
Happy Holidays

I put Propane injection on Pokey ('81 Wanderlodge, 3208 NA). Some increase in acceleration, obviously limited by no turbo, but an increase. Lots more difference on a turbo engine from what pals with the setup on turboed pickups say. I build my own setup for less than 250. Soleniod valve, a few switches, a flowmeter and some hose and fittings.
Supposedly there no downside, but more power must mean more strain on something. I don't think there is any cold start benefit, it doesn't take much at idle to make the engine start to miss. Not sure, but probably a good guess.

This article seems to investigate the subject with firsthand experimentation and nothing to sell. The thing is that it seems to work best with turbo (those turbo guys have it all). Although the 8% boost I think he said he got without turbo might be useful on hills for the rest of us. Depending on costs, it may be better to put the money toward the turbo first and then see if you still want more.

Chaz,
Steve here in Indy, what you might use instead of the propane is a product that has at least 70% 2-ETHEL -HEXEL NITRAITE

Ive read all that sharky has written on the subject, very negative in his assumtions and only experimented with a VW diesel with some poor conclusions. George Lowry used a Bully Dog system on a 903 Cummins and liked it aside from the price of the kit, he use to run a full time mix. I have run my own system for the last 8 years and its "on demand" for hills and grades, George and I use to speak often about it on these boards but decided to quit because we recieved too much crap from the "experts" about how we would blow up our engines and other catastropies, all from loud mouths whom had never touched the system
only repeated things they had heard. Chad, if your really interested E me off the board for a simple description....>>>Dan

Dan,
I've tried to take you up on the offer to CHAZ. I'd like to get a little more information about your system. With a strong likelyhood I'll clone it. Unfortunately your Email address is hidden. If you want to keep it hidden, that's fine but please email me, my addres is not hidden.
Thanks

Actually, I thought that Sharkey's article made the whole thing sound very promising although something I am not yet ready for. If your personal experience is even better, then it is something I would look forward to. At this point, I would not be thinking of more than a hill-and-passing system. How much of a boost have you been getting?
