With the adjuster screw flush with the bottom of the reg, it should be putting out approximately 500 PSI. Each full turn of the screw generates about 100 PSI difference (clockwise increases, counter-clockwise decreases). 500 PSI is as good a starting place as any, but if the internals are all stock, you'll likely have to go up to get decent velocities and efficiency.
