6.7L Cummins Forum

I own a 2008 Ram 6.7 - 6 Speed manual - Smarty Jr installed. Am interested in installing a water/methane injector system. I am looking for fuel milage gains and longevity, this truck has enough power and it is a work truck. I pull trailers sometimes and am in the process of of getting a 5th wheel camper. If the injector system is only for raw power and sled pullers I am not interested. If it is going to suck 5 gallons of the water/meth mixture in a short time I am not interested. I want the light or small injector similar to the Snow model and the smallest injector nozzle but possibly not that brand. Anyone try this or have one installed I am looking for the facts. Thanks in advance.

I have the Snow Performance with three injection nozzles. It is variable from less than a gallon an hour up to probably four. I rarely (twice) add any methanol ($10.00 a gallon). Seven gal reservoir. If you set it on "Tow Mode" it starts to inject at 10% (of max) at either 15 lbs of boost or if EGT hits 1000 deg. As boost or EGT climbs so does amount of injection. Climbing a mountain loaded heavily you might see it climb to 35%. I know some people who don't like the idea of water injection and some who do. My philosophy is that I live in a pretty dry area (low humidity) and all I'm doing is creating the environment of Prince Rupert or Vancouver (high humidity) Internal combustions run better in high humidity. The water turns to steam which increases compression, and soot particles are attracted to the water molecules and get blown out the exhaust.
