Reply to "Water Pump Replacement"

What I experienced with the Edelbrock water pump was that if I started turning my engine over 6000 rpm, there was a cavitation problem. This lead to a temporary increase in water temperature. From what I can tell, the Edelbrock water pump has an open impellor design, which can make it prone to cavitation. Other than that issue, it is certainly a quality water pump and might be fine for someone else's application. It just didn't do that well with my engine set up and will be replaced with a FlowKool pump. I also installed the SACC smaller aluminum pump pulley which does move more water than the stock pulley.
