I built one.
I installed it on my truck and have been driving around for a few days now.
No issues with it, opperates in the amp. range I want and puts out gas.
Truck runs smoother and seems to pull better on the low end.
I will drive the truck with and without the generator running and see how I am doing on gas savings.
I am running an 83 4x4 sporting the 2.8L.
Stock gearing.
31X10.50 tires.
I went with a "Joe Cell" design, stupid name but that's what people call 'em.
My cell configuration is: 3.00" Cathode 17" tall
2.50" Neutral 12" tall
2.25" Neutral 12" tall
2.00" Anode 12" tall
All tubes are 304SS
I made one or two small mistakes in fabricating this cell since I had never welded SS before but I am very pleased with it. All in all I would say the only surprise I had in building this cell was how hot SS welds when useing a MIG welder, everything else was very straight forward.
James, you have a PM.
