The flow rate will vary with engine speed, why do you need this info?

The cheaper pressed metal impeller pumps dont pump as well as the cast iron ones. Also if the inside of the timing case where the water pump sits is badly corroded or pitted the pump will be less efficient.

the problem with your overheating could be that the bore size of engine might be 50 or 60 thou over standard which will make it overheat

the water pump is just under a year old the impeller looks fine
i have now fitted an after market temp gauge and it seems to be running 90 plus most of the time
the block i bought the motor from tells me is standard bore i hope he is right
