here is what i found about afr


Air/Fuel Ratio Limits
6.0:1 Rich run limit
9.0:1 Low power, black smoke
11.5:1 Rich best torque at WOT
12.5:1 Safe best power at WOT
13.2:1 Lean best torque at WOT
14.7:1 Chemically ideal
15.5:1 Lean light load, part throttle
16.2:1 Best economy, part throttle
18-22:1 Lean run limit



Most engines will not run at the extreme ends of this scale due to individual design limitations of each engine. Extremely rich requires powerful ignition, and extremely lean requires very good cooling, and enough displacement that the huge drop off in torque still makes the car drivable and able to maintain a constant speed.

so what ratio would you reccommend for a daily driver using say a tdo5 running say 12-13 psi using a SAFC2 365cc injectors :confused:
