octain

Besides race gas what are you guys using to raise the octain in pump gas.

Well besides the different types of race gas, theres obviously 93 or 94 octane pump gas. Best if spiked with xylene, or used with an alky setup.

where would I find xylene at Who sells it and what ratio do you mix it at.

You can get it from Sherwin Williams, and you want to mix it about 3:1 from what I remember. Myself and most others use alky for the street, it cant be beat. Both methods are 02 friendly, unlike c16.

Ok let me make sure i have this right so you mix 3 gallons of gas to one gallon xylene right.And what does the xylene cost.

Dude, I cant really remember to the extent I want to tell you "yeah thats it". I only ran it a time or two. You would be well advised to look into alky for the street.

Ok edit: I just did the look up and 3 gallons of xylene to 1 gallon of 93 will give you 4 gallons ~ 100 octane. Be sure to add a couple of oz of Marvel Mystery oil. Will probably cost you around 20-25 bucks per 5gallon of xylene. Look into alchy!!!
