NA car, WOT, how lean is OK
My target AFRs are 12.8-13.1 at 89-101 kPa on my track only NA car.
I see other folks with as high as 14.7 (although they are boosted) at the same map levels?
I am looking for max power thus the 12.8 to 13.1 numbers but am just curious as to how lean is OK before I need to start worrying should it magically start running leaner on track... (and it seems to vary based on what gear I am in and high RPM/high gears have not seen much action on the street).

Last night may have been more eye opening than I thought it was, I found out I have to remove my A/F gauge, and I based on what I just read in regards to burnt valves I think I may have to rebuild my head. We noticed last night my car sometimes smells of raw fuel, I thought this was because I was running rich, but I never even considered a burned valve could allow raw fuel into the exhaust. This could suck.
