Yes I will be running 100 octane for roll-on and track events. But higher octane does nothing to cool IAT's. I have logs on back to back runs where my car was sitting at idle for a long period during a roll-on event. Meth didn't flow and IAT's hit 90c! Meth flowed on the next run and IAT's were around 36c. Made a HUGE power difference.
