We started at about 100 psi in the tank, took 12 shifts, and ended under just 45. But anyway, 12 shifts is shifting once every 10 seconds. So, if shifting is your only pneumatics, you can probably get by with one tank.

I mentioned the transmission because we used the AndyMarks which means you just need to use the 1/2" cylinders. If they did custom ones they might need larger which wouldn't work as well. If you check for air leaks and pump the PSI to the amount allowed it should last for a good number of shifts.
