With the right tune and quench, you can run that high of DCR with 93 octane. As a matter of fact, I will be doing just that very soon! (new cam in the works, cough cough)

you had better IM me... 
jake fusion figured mine as 9.0 on dcr and rane fine on 93 at 28 * wot timing,had slight retard at part throttle but that was mainly because of tuning issues i could have fixed myself with some tuning, but unfortunately at the strip i spun a bearing.
