Propane in a 7.3

I'm think about adding propane to my 7.3, not so much as for power but rather better gas mileage. has anyone done this without any problems surrounding the PMR's or anything else. Is there a safe way to install propane ?

thanks

Sorry, I have absolutely nothing to add to this thread other than when I saw the title "Propane in a 7.3" my first thought was, "The trick is keeping the propane IN a 7.3!"

Yep...I have heard the same thing. Propane is the fastest way to add an observation window to your block. Plus...with the price of propane...any gains you see in mpg will be eaten up by the cost of the 'pane.

So many opinions..........so little facts to base them on.....just jump on the bashing bandwagon.........why respond to a post asking for information and then not give any???

Propane fumigation, with a system that can control the amount of propane being delivered, is a very safe and effective way to increase mpg and horsepower. When the amount of propane can be varied, not just on or off and can be controlled with a constant monitoring source, then mpg gains can be realized. The idea behind proper propane fumigation/injection for mileage was never intended to displace diesel with propane, it is to use a "small" amount of propane at a given boost pressure to assist in the complete combustion of the diesel fuel. The propane is NOT making the power, it is it's effect on the diesel fuel, that the power and mpg increases come from and that is simply from a more complete burn. Even OTR trucks are getting "net" gains of 1-2 mpg and they use considerably more propane than our trucks do. It's all in how it is delivered.

Propane was also not intended to be used as Nitrous. A little is good, more does not mean better or more power. It is excess beyond what it takes to burn the diesel and just as too much #2, from large injectors, or nitrous, or methanol will cause problems so can too much propane .

Keep the timing out of the programming (which increases heat) , with or without propane, especially if you have PMR"s.

ProPAIN has a track record of blown motors and cracked pistons... What more infor do you need...

Believe it or not there are a good bit of OBS 7.3 that run Pain.. Most of them are RV'rs, and an increasing amount of new 7.3 are running it, as well.

As stated above, it should only be used in small quantities, and not for big power gains, and with out any advance in Timing Duration... When used for it's intend purposes it can be very reliable, when it is over used it becomes a volatile mix of fuel and air without a controllable burn and can result in serious damage..
