LP Injection and Old Diesels?

Prairie Oyster · Jul 7, 2011

This pre-turbo technology intrigued me. Has anyone had experiences with this? Disaster or limits? I heard of good efficiency and sometimes bent rods. I imagine mixture and timing were important. Some systems were called "Torque Topper". This is before my time. I need some schooling by the old timers. Thanks!

Do a net search on "diesel fumigation" and you'll find plenty of info. You may need to separate the wheat from the chaff,though. Good luck.

Nitrous oxide would be my drug of choice for an old non-turbo diesel, if I were only after power. It takes oxygen to burn the fuel, and airflow capability is what would limit you on getting the oxygen in. If I wanted to go further, I would go with water/methanol (washer fluid) injection. The methanol acts as a fuel and the water helps keep things from getting too hot.

If you get a diesel too lean with NOx, it won't burn valves like a gas engine, it just won't fire. But if you get it too rich with another fuel going in you will get detonation.

I recovered a wd9 that my father inlaw had used for 20 years. I noticed that there was a strange contraption on the side by the battery box. Asked the father inlaw and he said it was for a propane tank. On second look I spotted the regulator and hose going up to the intake. All manual operation. He said the increase in power was very noticeable. I also noticed the head had been changed. He also pointed out a small shot of propane and it started better when cold.
