Remote mech waterpump? Obtainable?

[Dave Flanders]

those electric pumps lose a ton of flow when working against any pressure, the Taurus was flowed at a true 30 psi pressure.


Curious what exactly is meant here by " 30 psi "? My understanding of this is that high overall system pressure, which is conducive to suppressing boiling and cavitation, results from what sort of cap relief pressure is used. Do we expect 30psi pressure head as additive to general system pressure from a non-positive displacement pump?

He tests the pumps at that pressure to get a true indication of how well they flow in a real engine. The electric ones probably flow great at zero pressure and the hose running downhill.
