Matt,Thanks for taking the time to reply. I asked the question as I was suspect. I am well aware of Aircraft use, in fact years back I was a USAF 135 pilot. In those days we used water injected into the 4 jet engines (the B-52 used 8 of those same engines) for every takeoff. It added about a third more power for takeoff only. I did call Banks Power Monday, their injection system is very high tech and produces a fine mist and has an electronic module and gauge that controls and monistors all. It is emissions legal in all states including CA. Since I have installed 2 of their header systems in the past, I am going to do that first. Here is a link to an article in RV Magazine where they installed the Banks Header system in an old Gas RV. They were impressed and it paid for itself in greatly improved fuel mileage. In my last installation, it took about 6 secs off the 0-60 times in an 05 workhorse with a 5 speed Allison, the 09 I now have has a 6 speed, so assume that will help some. Here is link:
