Davies Craig Electric Water Pump
I originally installed this becuase the OE water pump had a plastic impellor and was prone to catastrophic failure. I thought I might also get a few extra HP out of it as there would be no parasitic loss from driving the water pump and belt. I worked really quite well, but eventually decided to buy a OE replacement pump with a metal impellor and took this out. It's now sitting on the shelf with all the other "great ideas ."
