air fuel so i dont crack another ringland
so i cracked 2 piston ringlands the otherday
im running a garrett 60 trim on a stock gsr with about 7-8 psi 550 cc injectors on uberdata
what is the safe a/f for that amount of boost so i can stay away from broken ringlands
?
i was running 12.5:1 but i was told that was too lean

blown ringlands has nothing to do with ur a/f moron. its do to to mush pressure in your crankcase. read up on pcv valves and how to avoid that problem champ OR you could read the stickies that the mods made up top and we wouldnt have this discussion

I'd say, A/F has to do with you ring lands as well as PCV. If you detenating due to to much timing, you'll smoke you ringlands, but also what are you using for a PCV setup? Oil Catch can or did you leave it stock.

you can ask most of the tuners on here, leed, xenocron, kev, most tune for 11.8:1 air fuels in mid-upper rpm range in full boost.

11.5-12 :1 is fine as everyone already knows (except the morons) that minimal gains are to be had going any leaner anyway. Don't forget timing, that will cause broken ringlands. the way the planet and moon are aligned have been known to cause broken ringlands if not worse...
