Mackpro Posted April 2, 2008 Share Posted April 2, 2008 (edited) Had this 2000 CX Mack with a 400hp ETECH engine in the shop for some minor repair and I noticed something weird. The customer or someone had added a homemade propane injection set-up, they had a propane tank off of a fork lift mounted behind the cab and the regulator/valve was on the driver side of the engine, it had a pressure switch with wires on the intake manifold and small hose going into the air cleaner duct. The injector and piping went in right before the turbo intake. Here are some pics. Didnt get to talk to the owner about preformance gains. I have seen propane added on smaller diesel engines but has anyone else seen anything like this on a big engine.
