Can someone help me by giving me a basic idea of safe Timing values for a rotary i know you want to keep the AFRs around 11:1 but would going up to about 11.8:1 be to lean?

Where are you located?

11:8:1 is a little on the lean side, 11:5:1 is about as high as I would want to take it. 12:1 would be considered dangerous, 11:1 safe, 10:1 a little rich. Timing starting at 0 psi could be around 30-35 degrees then taper down to 15 degrees by 15psi. My timing is set at 36degrees before 0 psi, then 31 degrees at 0psi, then tapers down to 14degrees just after the 15psi mark and holds steady 14degrees the rest of the map. I tuned the car for 11:1 on the dyno last time I went and with these timing values its stayed together running 18psi for a couple years now, so in my mind its pretty safe.
