Fastassbanshee96 Posted July 5, 2012 Report Posted July 5, 2012 At what comp do you have to start running high octane fuel? Quote
do-work-son Posted July 5, 2012 Report Posted July 5, 2012 Thinking to be safe anything higher than 150 heard of guys at 160 an 165 area still on 92 but I wouldn't do it Quote
Fastassbanshee96 Posted July 5, 2012 Author Report Posted July 5, 2012 It's a 4 mil serval with r2 pipes and 22cc domes. I don't know the squish and am going to to comp test tonight. Just looking for a base line. I'm currently running race fuel but would like to get on pump for this weekend trip. Quote

Just looking for a base line. I'm currently running race fuel but would like to get on pump for this weekend trip. Im at sea level running 22cc domes & +4 timing on my cub using 100LL....I tried using 93 pump gas & it detonated really bad & blew an oring. AS stated before it all depends on your elevation, timing, compression ratio & squish. Quote
