Hard to say since tuning is such a variable. That will be the key.

9.1 is pretty safe


12.1 is safe if tuned for 91 octane

Tuning and cams effect it so much and you neglected to tell us your efi system and cam choice. do a search, help yourself.

id say 12:1 in that case. I had ctrs with 12.5:1+ on 93 and had slight knock at partial throttle in some places. Larger cams will eliminate some of that. Tuning is also key
