Hi Paul and Bill.
Yesterdays test carried out with a namometer tube in the inlet and a tube in the outlet.
Pump running at 3280 rpm with delivery of 100 litre per minute.
Inlet to block hieght and pump outlet set at 0.
Inlet pressure head .500 m.
Outlet pressure head 2.900 m.
Pressure differentail across block 2.400 m or lets say 4 lbs.
This is inline with the pressure head of 1.500 metre measured in the block tappings of my graph which is around .6 of the block curcuit.
This is the Toyota pump which is less than 1.5kg.
The stock mazda one is 4.5kg.
Regards Don

You need some back pressure in the system to fully characterize the
pump Don.

BTW I can't read wmf files Don. Can you send that as a jpg?
