Open is better than shut. (When shut, they load up with carbon, awaiting the next opportunity to dump in the engine and kill an apex seal).

Unfortunately, you will lose so much bottom end that you will have a faster 0-60 time with the ports shut than with them open. Obviously, rotary cars aren't any fun if they run out of power around 5500 rpm, so wiring the ports open is the preferred way (even though the car is slower).

You will make significantly less horsepower with the ports shut, but as I mentioned before, your average torque is enough higher that the shut-port acceleration (0-60) is better.

Fully functional ports are definately preferred (or just go 4-port and get it over with).
