Excellent point. I actually worded that poorly. Thanks for pointing that out. Here is what really happened. About 20 years ago I needed a new radiator. After a lot of research, I went with a Griffin Radiator. The salesman talked me into their custom built fan/shroud setup also. It was rather expensive. He said it was good up to 600 HP. The radiator is GREAT, but the electric fan setup just did not work well.
