How many GPM from the water pump?

[steved0x]

I knew a guy with a 944 and an electric water pump that he could control from the cockpit and essentially set the water temp wherever he wanted by speeding up or slowing down the pump. But I guess you still have to start with the right approximate flow... I have no idea unfortunately the GPM :-(

Woody; I think what will determine the GPM is the size of the coolant pipes to the front of the car. I know you know the diameter of your pipes, but my thought was for 1.5" id pipe size you could flow 35 GPM at 0 psi. Attached is a chart that can give you various pipe diameters.
