I have never used an electric water pump. I am considering it. If I install an electric water pump, can I use it to cool down the engine between rounds at the drag strip? If you run your electric pump with the engine off, does the coolant flow or does the tstat stop the flow?
Thanks for the help.
Wherever your Tstat is set, it will cool it to that point.
I have mine set up to run when I want with the motor off. The pump along with the fan will allow you to pretty much hot lap it if you want. Takes only a few minutes to cool the motor down and then I would leave the fan on to remove as much excess heat from the rest of the engine bay and prevent heat soak. I used to run about every 15-20 minutes with no drop in times due to heating issues.
