As I have mentioned, I have removed the water pump from my engine and installed a Davies Craig electric pump. I will go into detail about this mod later, but I want to share an observation I made in the process.
The engine is a 1.9L with high compression and a bunch of mods.
I am still in the process of running it in and setting it up.
But extented drives so far have shown that the engine is very cold blooded. With the electric pump, the coolant temp usually runs around 160°F even when pushed. Granted it is only about 55°F outside, but the pump is only running it its lowest setting at that point (6V, 10 sec on, 30 sec off), so there is alot more pumping flow rate to be had.
My point is, if you have temperature issues, and you have already recored the radiator (which should be the first step), it would be worthwhile to look into an auxillary electric water pump to increase the flow rate when things heat up. There iseems to be a lot of potential there.
Note that I haven't tested this on a really hot summer day yet.
(At this point, I would not recommend a full conversion like I did for a street car, because the swap removes the thermostat, so the engine takes a long time to heat up. Also, the control algorithm and the cycling of the pump results in large variations and jumps in coolant temp.)
