C16 and A/F ratios

Well, we all know the target A/F for pump gas is 11.5. So what is a safe A/F for C16 running say 20 to 25 psi? Still 11.5 or can we go a little leaner?

A little leaner. My mixtures were around 12.0 with 8 degrees into it @ 25+ psi

depends on you're timing and intake/coolant temps. if you can get timing down and have your temps reasonably cool, you can dyno to low 12's - 12.5. this'll net you around high 12's when actually moving, as you'll be a touch leaner when driving vs. on the dyno.
