Does impeller torque stay constant as RPMs rise after cavitation or also increase?
I have an aftermarket pump pully i'd like to use on a 360LA but it is a bit smaller diameter than stock.

You guys that weld a disk to the blades to stop cavitation, why and what problem did it solve?
Some water pumps have more blades than others-is this for low performance engines only?
Could water pressure blow hoses off if you overdrive the pump and don't allow cavitation?

At what RPM does a typical parts store reman water pump start to rob HP needlessly?
