Ok probably stirring up the pot . I installed a propane injection unit on my 6v92ta,total cost about $1100. Has been in for 1 year. You can turn it on or off at any time from the drivers seat.My son and I did a test on a controlled route with a hill in the test. Each time I gained an extra gear and lost 10 seconds off the route test with the propane on. We did the test 3 times on and 3 times off, the same each time.It has given me the extra power needed for the up hill runs.I turn it off when not in the hills.I have the regulator set low on the amount of propane injected. The only difference I have noticed is I use a little less oil on a long run.As far as long term use time will tell. At present we only put on about 8-10 k a year.                          dave

Your preaching to the choir Dave,, its well known that propane "mixing" (its not injected) works well for turboed and "A" timed engines. Propane is even more effective on 4 stroke diesel engines than 2 strokes..>>>Dan

This is something I have always had an interest in although I do not have a turbo.  Many reports seem to say it helps a natural engine, just not quite as much.  There are those that create their own systems using a steady flow of propane.  I have also heard about systems that can regulate the propane flow according to the DD blower, which would be similar to the turbo system.

The parts I don't like about the propane injection for the amount of injected propane the same amount of air is displaced and then the water content bothers me

good luck

 You will probably find more water vapor in despensed diesel fuel than propane vapor. Internal combustion averages between 14/17 to 1 for efficient combustion,, thats a lot of air to work with, particularly under blower pressure.>>>Dan

Cliff, would the minor amount of water possibly act as a cleaner/steam washer? I've heard of peeps injecting water to keep things sparkly in there. I green when it comes to diesel....just curious

With a diesel,, that would be an excellent way to ruin your injectors quickly.>>>Dan

Scott I never saw a water injector but I do spray a about a qt of water running a DD @1/2 throttle sometimes if they have a carbon knock and it will stop the knock.

Years back on gasoline engines running leaded gas you could do the same and it would remove buildup without removing the head that practice was common on the Onan generators even at dealers fwiw

 As far as a propane setup on a 2 stroke the way it is design and the air at over 200 degrees under the  aftercooler on turbo engine I will wait and see

  If you use 2-Ethyl-Hexyl-Nitrate in you fuel, you will see and increase in you power, Diesel sound (knocking)

  will no longer be there,less smoke. Ratio is 1 qt to 112 gal. will increase cetane 6 numbers. The higher the

  cetane rating of the fuel the better fuel mileage.

    Is this "Power Service - Diesel Kleen" (silver bottle summer, more cetane boost; white bottle winter, less cetane boost but anti-gel and water removal)?

     Bottle of "Power Service" = $16.99/ at dah Waw*Mott; $19.99 at truck stops.   Gallon of gas:  $3.50.  Sounds like a good plan to me.  How much gas to you need to buy to get enough EHN to do any good?
