I'm going racing this weekend and the weather's gonna be very hot (37C or 101F) and very dry ~20% humdity. My mods are in my sig and my C/R is a bit over 10:1 and my heads are iron.
Should I mix a few galons of 103 octane with 94 pump gas? I read somewhere that in hot, dry conditions octane requireets increase.
Any opinions on this?
