Progressive Propane

[06ARMADILLO]

I DEEPLY apologise if this is a repost. I dislike it when someone is too lazy to use the search button (I actually did search for this one).

So, what I am looking for is a propane injection system for my truck. Now hold on before you direct me to just any vendor. I am wanting the progressive kit that isn't intended as a horsepower boost, but rather as a fuel economy boost. I happened to read an article about a guy that had one installed on his truck and was intending to sell/market these kits for diesel trucks.

from what I heard, our trucks don't get near the mileage benefit as the Cummins do for these kits. only moderate mileage gains on the Power Strokes, but some Cummins guys are getting 30+ mpg with these things. Maybe someone will chime in that has one on a PSD and can give some real world results.

My father-in-law has a propane system for several years now on his rig. (7.3) He also uses it for mileage for long drives and trailering. I don't know the exact numbers off it but he seems to like it. I'll have to see if I can remember what system it is.

Isn't it a kick in the teeth that the cummins benefits so well from these things, and all of their parts are SO cheap?! I do take solace in knowing that the trucks themselves (Mopar) are piles of S#!T though. Can get a Cummins in an F650 I think..

I read somewhere that engine internals LOVEEEE a good dose of Propane....

This setup had a new controller aimed at adding just enough propane to gain fuel economy. The amount of flow changed with throttle position. It was pretty slick.

I want to say that it is like the CNG setup that one guy was running in the diesel power shootout recently. His truck was a Durasnatch I think.

oh yeah, he also got like 35+ mpg in the chevy.

here is one that uses the boost to determine flow of propane

Diesel propane injection systems, computer programmers, water vapor air fuel system seperators

Father-in-law has over 100,000 miles on a PMR block and propane on for probably 70-80,000 of 'em.

Now given, that is not running propane all the time, nor when he does run it, he runs it lean just to give a little extra for towing and mileage. Every once and awhile he might bump it up a little.

As with a lot of things, some things are good in moderation.

Did we get used to fuel prices? Or just used?
