RV8 Electric Water Pump

I have been a lot more impressed with the electric water pump than I thought I would be. I was sliding down a hill side, somewhat out of control and I decided my safest escape from Gravity was a decent sized tree. I managed to let go of the brakes and steer so that I hit it smack in the middle of the front. This worked great as I managed to save the chassis rails. But the upshot was I broke the milemarker hydraulic off its base plate and put it into the water pump
As most off road incidents are a good excuse to buy more shiny new parts, I decided the rear rad set up would like a Craig Davis electric water pump (with the proper controller). This meant I could run the alternator V belt with more pulley coverage and not worry about having it adjusted on the tight side for running in deep water. It also meant I could move the winch back a few inches. With a 3" gap between drum and fair lead the rope is better at reeving and stays off the cheeks.
But the real gain was in cooling efficiency. I knew they were good for racing with high engine RPM, but I didn't think it would make a big difference for slow competition work. The reality is that the electronics means a slow pump gives a quick warm up, but also the extra flow when it is warm means the electric fans run less. Also it cools after the engine has been turned off which is nice. Plus it can run at full speed/flow while the engine is at 1200rpm.
In theory I just replaced two mechanical parts that are fairly reliable with an electric doohicky, but as I run two electric fans I kind of already took that leap of faith.
Just like going dry sump it seems to be a slice of technology that this aged engine rather likes

On a side note the water pump housing was a bit of a hassle to weld. If you put too much Tig heat into it moving the porting it kind of bubbles up and fights back.

By this, do you mean that you modified the original water pump to allow for connection of the electric one?

This has been a topic of discussion with AFIRover and I in planning for his build. He is worried about porosity or other contaminants in the aluminium, but I'm not skeered
