As soon as the RTV pump gasket gets a chance to cure I will pressurize
the system and see if it makes any difference. I need to change out the

lower

pressure gage for one that reads both positive and negative.

I think I need at least a 5 HP mill. There is one on the East end of SZP.

I am also planning on finding some plexi tubing and inserting it into
the loop on the intake side.

The heat is not a serious problem yet. I can still hold my hand on it.

Paul,
Is it better than the standard Mazda water pump?
Pretty impressive testing system.

I have no idea at this point in time. I guess I could fabricate an adpator to test 
the stock Mazda pump housing with the same test rig. So far Don and Bill's test set
up has been open loop so it is apples and oranges. I am seeing twice the flow
at zero pressure than Bill and Don saw. Don did the Toyota pump but I am not
sure how he measured the pressure.
