U dont need a egt on a non turbo because the turbo is wat rises the temp. All the extra fuel not burnt will go out the exhaust. The most propane will incress ur egt's is like 100-200 degrees no matter how much fuel is dumped in there

 

U got to remember a turbo crams air in ur engine n that is wat helps burn more fuel then the propane helps burn even more fuel which is going to raise ur egt's alot so if ur running no turbo just ur propane u really dont need on cuz ur engine is only going to burn so much fuel before it cant burn any more cuz it needs that extra air from a turbo. So any extra fuel just get produced into black smoke

 

Hehehe that truck died years ago! I got a 97 powerstroke now! I finally figured out LEAVE IT ALONE IT WILL LAST LONGER!

 

more fuel for a over fueled engine???
forget the propane or turning up the pump until you can get rid of the black smoke under load.
ie: you need more air......
once you install a pyro meter. to get your base line.
install a stock sized turbo. if your engine never came with one, size it appropriatly.
review your new pyro temps.
then start adding more fuel, injection timing, propane, new cam(s), change compression, ect.
remember the propane is to help burn the fuel that doesn't atomize properly.
any black smoke you see is just wasted fuel.

i dont know what you would use to turn the solinoid on and off besides a switch on the pedal, i just got my propane kit built and put on my truck tonight have not got a chance to go and drive it yet had a few to many, but i used an adjustable pressure switch to control my solinoid, mine is in line to my map sensor and i used a 12/24v air solinoid to turn the flow on and off, i used a adjustable pressure/flow regulator from tejassmokers.com, got mine set at 10psi right now but i have a powerstroke and get up to 23psi of boost under heavy load and 3800rpm. my brothers friend is running the same set up on his sd as i just built and his works great he has about a 50hp increase with his set at 12psi. you can get the air soliniods from a place that supplies air horns for vehicles they would know exactly what you need. i would really like to know what kind of increase you get when you get it figured out cause i am looking for some more poewer for my 87 ford ranger and i have a 7.3l idi in it and there is not room with how i have it in to fit a turbo so any extra power the better

 

OMG that "FREE" diesel could cost you a whole lot of fines if you ever get stopped by DOT and they dip your tank. RED means no road tax has been payed on it. THE MAN doesn't like his peeps not paying TAXES.

 

just get a hobbes switch, they come in two forms of pressure sensing.
low pressure/vacuum. or high pressure/boost.
they are available at most parts stores. (they are like a low oil pressure switch).
i used one with a water injection system on a high compression gas engine..

 

Wrong. All the extra fuel is what raises egts. More air would lower temps. Diesels like lean air/fuel ratios that is why in theory they are more efficient and if you could properly regulate the propane it is that much better
