knjlexus Posted May 30, 2012 Author Report Share Posted May 30, 2012 I'm at 1538 feet. And I run 93 octane. Quote Link to comment Share on other sites More sharing options...
erickson483 Posted May 30, 2012 Report Share Posted May 30, 2012 I'd say 20 but you'd probably be ok at 19 with your elevation. Maybe someone else can chime in too. Quote Link to comment Share on other sites More sharing options...
Chip M Posted May 31, 2012 Report Share Posted May 31, 2012 I run 19's at about sea level and my compression is 165. I am not sure how much difference our elevations would make on your compression but I run Sunoco 100 octane. The guy I got the quad from ran 93 and did not have any problem but I knew it was right on the edge and I did a fresh rebuild and wanted to do my best to avoid deto. Good luck.
