Race gas vs pump gas on lower compression street/strip motor

I did this in my mid 10sec car. Use to run 110 race gas. Switched to a fuel station that sells 93 with no ethanol cut and the only change I saw was a slight water temperature increase. Still runs 10.63's. If I remember I changed the timing ever so slightly. Something like 2 or 3 degrees.
