I am going to change my radiator set-up from two radiators in series to two in parrellel. I would like to downsize the water tubes from/to the engine. Because the flow to each rad will be cut in half this seams reasonable. What am I overlooking?
The existing tubes are 1.25" x .065" 6061T6 AL. I would like to go to something like 1"x.035" or even 7/8" x .035" 6061T6. Its easier to route, less expensive and saves a couple of pounds. Has anyone ever gone that small or thin on their water tubes?
