Psh Home made race gas(via your local chemical wholesaler or work hookup) One gallon of Propylene oxide(Oxygenator in the nitromethane kind of way)which EXPENSIVE, one gallon of Tolulene (sherwin williams for $14 bucks, omit if not advancing timing or increasing boost/compression) to ten gallons of premium gas. The propylene oxide may be federally controlled now (F**King anti-terrorist laws) but it's good for about a 6% boost in power, and the tolulene is a knock inhibitor that bumps the octane rating of the fuel to around 110-115 letting you crank the boost. You will go through A LOT of fuel but it's power in a can.
Very few of the octane boosters at the advance auto work the one that worked the best was the NOS octane booster in the box used 2-3 per tank and it would let you run a 100 octane map. The ones that say they will raise your octane 6 points mean .6 octane hence 6 "points." The gallon of tolulene beats all in that department ~7 full numbers for $14 and ~14 for $28. Careful though the PO and Tolulene will take their toll on plastics if you use them continously so i'd save it for track days and flush it out with 93 at the end.
