so I've been checking around for local high octane and found VP-110 Race gas for $8/gal.
If I mix 1 gallon of 110 into 4.5 gallons of 91 to fill my 5.5 gallon VP Race fuel jug, it should be put the gas at: (4.5gal*91octanes)+(1gal*110octanes)/5.5gal = 94.4 octane.
Can I get a second opinion that I will be safe running 180-185psi with the Timing Jumped at that octane?
I'm going to setup my jumper, so I can turn it on or off more easily. thinking of using a hard switch, in case I'm in a scenario I can't get past 91 octane.
