Iwas wandering what compressoin you can run until you have to run straight race gas, half and half would be fine?

 

You can run a 11-1 on super unleaded, but when the going gets tough you need more octance(hot summer days, racing hills, max load)

 

While on this subject, if there is a need to put a slight octane booster, is there a brand that is recommended that I can find at like Auto Zone or something. I am speaking of an 11:1 stage one setup and using 93 octane. Maybe something like those STP treatment bottles that could maybe just boost a 5 gallon jug up a couple of octanes.[img]i/expressions/face-icon-small-happy.gif[/img]

 

go to the paint store and buy a gallon of Xlyol and toulenne.
