I need to find a good octane booster. Have 48 Flat Head Ford bored and stroked. 160HP on dyno. Runs good on 93 octane but hard to find. Thanks
(quoted from post at 08:48:40 10/15/18) Just add more corn ethanol, it has 113 octane and is very popular on this forum.

..... Toluene will also raise octane.
(quoted from post at 19:26:33 10/15/18) Correct me if I am wrong: I believe aviation gas and auto fuel use a different way of measuring octane.
(quoted from post at 10:54:12 10/16/18) Sunoco, VP, and Turbo Blue racing gas are the brands most used in my area, and typically have higher RON ratings than 100LL with most falling in the 104-110 range. A few as low as 97.5 and some over 120.
I can't imagine a flathead making enough compression to need racing fuel.
A word of advice to the OP..... If you're going to experiment with fuels start off jetted rich and ignition retarded and tune from there.

Other than C16 race gas . I don’t see any pump fuel with a higher RON .
(quoted from post at 05:05:06 10/19/18) You want to be careful using 100LL in a flathead engine. While you will see it says Low Lead but it still contains 3 times more lead than old leaded car gas had. Lycoming and Continental both had warnings about lead build up on valve stems causing sticking.
I have used it quite a bit especially when storing for winter I tried it in my Farmall Cub and she would always stick valves did a little research and found the Lycoming bulletin from years ago.
No problems at all with the overhead valve engines they love it.
