Alright I put this together just to simplify a lot of the numbers that were coming out of the CBR steering pump thread, but figured it could be handy for anyone tinkering with their steering system. It's a basic calculator that determines pump RPM for different engine speeds based on pulley sizes, then calculates how much the pump is theoretically flowing based on pump displacement. Between P pumps, TC pumps, CB/CBR pumps and trophy truck pumps there are various displacements, so adjust that cu/in per revolution to your pump size (I may add some reference data at a later date). Then it has an integrated feature for when the factory flow control opens, and has an assumed efficiency of that valve (90% seems pretty close to some reference data I've seen).
Then if you calculate the volume of your steering system (piston surface area * stroke of steering box + ram piston surface area minus shaft surface area * stroke of ram) and enter those numbers, you can get theoretical lock to lock speed.

*EDIT*
Update V1.3......1-15-21
-Added Pump Pressure Output
-Added Steering Force (At Knucke) Note: Steering Ram stroke is needed for math to dictate knuckle travel, even if not using assist)
