Hi Ed: > Great work Todd. Do you know what year the Ford and GM cores were > (approx?). Your results on the Ford and GM cores are the direct opposite > according to the Contact! article on those two cores. I'm not sure, but I'd expect that the cores were from a late model truck. The wrecker where I got them only deals with trucks, and specializes in diesel performance parts. They were all still mounted in the air plenum, but removed from the trucks and just stacked up in a big pile. I know that each plenum had make, model and year written on it but I didn't pay it much attention as I dismantled it and removed the cores right in the wrecking yard. I doubt that the diesel cores are any different than the gas engine cores, but it may be a factor. > Getting that much flow with that low a current draw is > another fact that > is > contrary to "conventional" wisdom of how much power a water pump > consumes. As I just mentioned in a previous e-mail, current flow is almost 10x higher than I originally reported, but still far lower than others had projected. I'm somewhat embarrassed by my error in reading the DMM, but I was concentrating on getting the flow rates accurate, and failed to notice that the autoranging did not auto detect AC/DC, but must be manually set. While digital meters are far superior to the old analog meters, they do have the ability to fool you if not paying attention. . Now, I wonder if I could swap my GM > cores for > Ford cores in time for Sun & Fun? Hummmm. I think you're joking here, but if not maybe you should wait till I actually get this thing running and in the air, as that will be the ultimate test. S.
