How high of compression can you have and still use 92 octane?
How high of compression can you have and still use regular gas?

 

According to a artical in the April 2002 issue of ATVSport it is about 12 to 1 for 92octane and 11 to 1 for 88..

 

Well, the Cannondales are 12.5:1 and require 93 octane, I think so right around 12.5:1. I think pretty much stock compression is about as high as you can go with the rest of the sport quads on 87 octane, but I may be wrong.

 

Thanks for the info.
