I've come across this articles about fitting an LPG kit on turbo diesel engines. Seems to increase HorsePower and gas mileage, along with other benefits (cleaner emissions, engine...). Kit is installed as to inject 15/20% LPG into combustion chamber along with regular diesel. Not a full LPG conversion like gasoline engines. Has anybody performed that kind of installation on a 4Trak?
Think it's pretty interesting.....
