mopar1rules Posted April 24, 2010 Report Share Posted April 24, 2010 All depends on your elevation,Squish and timing Not so much the squish, but more so the trapped comp ratio. Quote Link to comment Share on other sites More sharing options...
firebanshee Posted April 24, 2010 Report Share Posted April 24, 2010 I'm in Medina, Ohio and at 1089 ft I think at that elevation you would be ok with 93 octane but at sea level you are on that fine line.imo Quote Link to comment Share on other sites More sharing options...
AKheathen Posted April 24, 2010 Report Share Posted April 24, 2010 what pipes are you running, and is the timing stock? you can do it with the .050" squish, stock timing, and mid or mid-top pipes, but you cannot go lean at all, and don't run old gas Quote Link to comment Share on other sites More sharing options...

I ride everyday so gas never gets old. How do you check squish? What shold be the max trapped comp ratio? Quote Link to comment Share on other sites More sharing options...
