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.

26 gallons per minute

Inlet to block hieght and pump outlet set at 0.
Inlet pressure head .500 m. = 1.47 foot
1.47 /.45 psi per foot = 3.7 psi

Outlet pressure head 2.900 m. = 8.8 feet
8.8 /.45 psi per foot = 20 psi


Pressure differentail across block 2.400 m or lets say 4 lbs.

8 feet / .45 or 18 psi.

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.

5 feet / .45 or  11 psi.


This is the Toyota pump which is less than 1.5kg.

3.4 pounds

The stock mazda one is 4.5kg.

10 pounds


Regards Don

The last two files did not come across again so I attached some earlier
files of the Toyota pump. What is a .wmf file Don?

Interesting single point data but now we need a radiator in the circuit or 
a valve so you can gather data through out the outlet pressure
range. That way we can pick a radiator pressure drop.
