To boost pump gas to high enough octane with boosters would cost more than race gas. Summit has some stuff...so I bought it. After doing some math it would have cost just as much to get the real stuff. I plan on visiting my local air strip for AvGas. It is 110 and NO alcohol.

Tetra-ethyl lead (T.E.L.) is still for sale in bulk,
and is of course used in Commercially sold aviation gasoline.
You must use protective gloves when blending in TEL as it is poisonous.
MMT is for sale, and is cheaper in bulk by far, than the small cans of MMT containing octane booster sold in auto parts stores. MMT is still widely used in overseas gasoline, and is advertised as a “green chemical” because it reduces greenhouse gases emitted per mile driven.
The first octane booster discovered was Iodine, like used as antiseptic for cuts.
E85 is an readily available alternative with higher octane 105 AKI alternative if you are willing to change air fuel ratio.
Methanol and water blends sprayed into intake manifolds both boost Octane rating, and cool the intake charge for an additional power gain. I used the Snow Performance kit on my old Charger build. Works very well.

I had some good use with the “race gas” concentrate from summit. You mix one with the 20 gallons and it worked well.

The active ingredient in most of them used to be toluene. Google up toluene and octane and you will find some info and recipes.
Here in the Great White North Toluene is CDN$25 a gallon at Home Depot. A gallon of Klotz is $60+ at Summit.

Good luck finding Toluene in the states. Apparently there are some people that prefer to kill off the three brain cells they were born with by inhaling it, so it's been generally unavailable and replaced by Xylol Xylene. You can get it, but it's not all that easy anymore nor is it cheap.

The new name for the old Ethyl Corp is Afton Their presently sold Octane boosting additives https://www.aftonchemical.com/SBU/Fuels/OctaneAdditivesI would not be surprised if the Summit product that costs $1 per ounce is just re-bottled Afton additive with a large mark-up, or perhaps a Chinese made competitor to Afton.

I used Klotz in my 13:1 Hemi mixed with 93 octagon unleaded for the street drive portion of drag week. I didn't drive it hard on the street, but I never had a ping or a rattle. I switched over to race gas for the track. klotz

Well,?
The car Im trying to buy is gonna need something besides pump gas.
Current owner mixes high test and race fuel. which gets expensive
Im looking at alternatives if at all possible .
car is approx 11.5 to 1 , street hemi I read that Hemi's like higher compression. It would be nice to be able to effectively run a Snow Water/ethanol injection set-up to eliminate your detonation issues. Once dialed in, simply adding a mixture of water and ethanol would sure be easy and relatively inexpensive. You could even run a larger tank to last through multiple fill ups of pump swill. Try and find out how the guy has his timing curve set-up. It may not be optimal as far as reducing gas knock.
