Best Performance for 3500ft?

[250rsrule]

Live in the OKlahoma panhandle @ 3500 ft above sea level. Whats is the smallest dome I could use if I wanna stick with 91 octane. I've heard of people running 150psi w/ pump gas without a problem. If so then 18cc domes would work fine, but that seems kinda questionable to me. Any suggestions? Plan on using a NOSS Head.

18cc should work at that altitude but I would try to get at least 93 octane. To be safe maybe you should run 19cc domes, 18s might be too borderline.

The only way i can get 93 is to get 91 + Octane booster. Nearest place that sells 93 is Amarillo, Tx which is a 2 hour drive.

You might get away with 18cc domes but 19cc would probably be a better choice. You would be 'on the edge' with 18's. You will notice a lot of difference between a stock head and 19cc domes but not nearly as much between 19cc and 18cc domes.
