Ever considered xylene or toluene? I'm looking at the conversion tables and I think the way they do it is by basic average ratio's. If thats the case, xylene is 117 or there abouts and you can mix 1 gallon of that per 8 gallons of 91 to 1 gallon of that and get an average higher then 4:1 with 100 octane.

It's odd even not under boost, the car runs SO much smoother with a decent octane gas as opposed to our 91 =/
