I have a friend who has installed this contraption on his 2005 (I think) Dodge four-door 2WD pickup with the 4.7 V8 which is stock save for this system. He has so far seen a huge increase in highway mpg, from 14 to 20. I too have been very skeptical of this setup, but am now considering installing it on my HD. (I am only CONSIDERING it right now). My friend currently is using one water jar, but is increasing to a six-pack soon.
One of the first things he noticed after getting the system installed and working with the engine was how much quieter and smoother the engine was. I mention that because he's not a motorhead by hobby but is an electrician by trade. I couldn't tell the difference in sound, but it's his truck and I've never driven it. There is a box that allows you to switch the timing from "city" and "highway," which allows more timing when in the city mode. The city mode does give you more low-end power to help acceleration, but is not needed when on the highway. I'm waiting on his more long-term results, just to see how the truck holds up overall. He does not tow with his truck but does haul gear and people fairly regularly, with work sites ranging from Ft Huachuca to Yuma (lots of highway driving). And all this has been going on during summer, with temps easily in the 100s and sometimes the 110s. |
