My turbo pro runs between 11.8 - 14. The supposed to run closer to 14. That's on straight av gas, at anywhere between 2000ft- 5000ft. I haven't had it long, and haven't had it higher up yet. But I do know the numbers are where there supposed to be.
14.7 is the ideal number for complete mixture and burn but thats the boarder of melt down for sure 11-13 is a safe range. being a bit richer helps cool your motor and lubricate as well as keeping her going. with the air /fuel gauge you can watch your rpms verus it to see if your low mid or high rpm ranges should be leaner or richer. just do a quick search on google about air/fuel gauge function.
So I ran sled in revy and a/f gauge was at 12.5 on good long hard pull and egt was at 1175-1200 deg and sled pulled really well.Just incase someone was wondering what I found.
