Perfect N/A Air/Fuel
Hey guys I have a reflash with all the bolt ons with stock cams and I was wondering what the perfect air/fuel was at WOT. My wideband is saying about 12.0/1 and I thought this was a little rich. The car does really pull though and I haven't had the car dynoed just yet. I hope to when I get back in Florida. Just curious.

Yeah, 12:1 NA won't hurt anything no doubt, but you're leaving lots of safe power on the table running so rich afr. For a point of reference - FI on the otherhand, you'd want to run around 10.5:1~11:1.

truth is you will vary between a given range. It will never be exactly 13.4 throughout the entire RPM band, but rather fluxuate depending on your mods/tuning. Do you have datalogging capability? Ideally you want 14.7 parts of air per part of fuel, that is the optimum stochiometric ratio. Like Gothchick said, when you go FI though, you want to run a little rich to safegaurd against detonation.
