Build your next motor with a ton of compression and pump gas and maybe you'll be the 2nd in a million to get away with it. Not doubting lluciano77 but we see detonation on iron headed motors at 10:1 a lot, and that is with 93. 11:1 with aluminum heads such as AFR 195's is not easy either with pump 93. Boarderline on the edge.
