No just 91 here I can get aviation fuel at around 103 octane but cost around 6 bucks a gallon and 110 or better is about 8 bucks per gallon.i think he would be better off with compression at 10 or lower using Iron cylinder heads.
with aluminum he can push it up, but so is the price of the build and fue!!
i can still get 93 octane here near the east coast. Can you there?
