For all you Toluene users...
What proportions do you like to use? According to my calculations, 1 gallon of Toluene mixed with 4 gallons of 93 unleaded yeilds:
(1 * 114) + (4 * 93) / 5 = 97.2 octane
How will this octane level affect my performance at 7-9 psi? Did you notice a change in EGT's? Thanks!

Re: For all you Toluene users... (yellowhonda88)
55 gallon drum of 101 unleaded in the garage.... best solution for those early mornings. Especially when you can get it for $1.66 a gallon...
Most race gas distributors will sell to individuals, especially if you do a group buy like we have done.

Richard Lassiter's "How to Mix Your Own Brew"
FORMULA 1
Toulene
R+M/2...114
Cost...$2.50/gal
Mixtures with 92 Octane Premium
10%...94.2 Octane
20%...96.4 Octane
30%...98.6 Octane
Notes: Common ingredient in Octane Boosters in a can. 12-16 ounces will only raise octane 2-3 *points*, I.e. from 92 to 92.3. Often costs $3-5 for 12-16 ounces, when it can be purchased for less than $3/gal at chemical supply houses or paint stores.
FORMULA 2
Xylene
R+M/2...117
Cost...$2.75/gal
Mixtures with 92 Octane Premium
10%...94.5 Octane
20%...97.0 Octane
30%...99.5 Octane
Notes: Similar to Toulene. 12-16 ounces will only raise octane 2-3 *points*, I.e. from 92 to 92.3. Usually mixed with Toulene and advertised as *race formula*.
FORMULA 3
Methyl-tertiary-butyl-ether (MTBE)
R+M/2...118
Cost...$3.50/gal
Mixtures with 92 Octane Premium
10%...94.6 Octane
20%...97.2 Octane
30%...99.8 Octane
Notes: Oxygenate. Very common in octane booster products. Has lower BTU content than toulene or xylene, but oxygenate effect makes the gasoline burn better and produce more energy.
FORMULA 4
Methanol or Ethanol
R+M/2...101
Cost...$0.60 - $1.75/gal
Mixtures with 92 Octane Premium
10%...94.3 Octane (Methanol)
10%...94.7 Octane (Ethanol)
20%...Not Recommended
Notes: Methanol is wood alcohol. Ethanol is grain alcohol and found in Gasohol in 10% ratios. Both alcohols are mildly corrosive and will eat gas tank linings, rubber and aluminum if used in excessive ratios. Main ingredient in "Gas Dryers", combines with water.
FORMULA 5
Isopropyl Alcohol and Tertiary Butyl Alcohol
R+M/2...101
Cost...$0.60-$1.50/gal
Mixtures with 92 Octane Premium
10%...94.5 Octane
20%...Not Recommended
30%...Not Recommended
Notes: Similar to Methanol/Ethanol. Isopropyl Alcohol is simply rubbing alcohol.
MAKE YOUR OWN OCTANE BOOST
How to make your own octane booster (this is the basic formula of one of the popular octane booster products). To make eight 16 ounce bottles (128 oz = 1 gal):
100 oz of toulene for octane boost
25 oz of mineral spirits (cleaning agent)
3 oz of transmission fluid (lubricating agent)
This product is advertised as "octane booster with cleaning agent *and* lubricating agent!". Diesel fuel or kerosene can be substituted for mineral spirits and light turbine oil can be substituted for transmission fluid. Color can be added with petroleum dyes.

Re: For all you Toluene users... (hybridvteceg)
Yep, your formula is good. If you're gonna mix it though, make sure you give the gas time to mix together, so don't make your mix, then hit the streets and make an 18PSI blast down your street and expect it not to detonate What I did when I had my old mustang (9:1 306, T-trim @ 16 psi, no IC) I would fill it up 10 gallons of 89 octane, 12 gallons of xylene, let it sit overnight, and i'd be ready to rock with a full tank of equivalent to about 104 octane Worked nice for me because it's hella-hard to get racegas here, and I just prowled around the streets with it, no road trips.
