You know us at RI, we love our 3x3 doors. This one uses special game mechanics so that opening only takes 3 redstone ticks! 3FAST5U
For an even speedier entry, a 2x1 entrance opens INSTANTLY from the moment it's de-powered, so you can rocket on through.
Remember this door is very complicated, so if it doesn't work the first time, watch the tutorial again!
