Air/Fuel Ratio Questions

[jymboslice]

Hey, I dont think i've noticed a thread on this so thats why im asking this question. I just got an aeroforce interceptor gauge for my 12' and want to know what a good air/fuel ratio is for the N/A 5.0? Mine idles right around 14.00 and when under WOT goes down to about 12.00, sometimes below even into the 11's. Am i running too lean at idle or WOT?

Any info is appreciated, Thanks

the idle is a/f is fine, and the wot a/f is very safe. looks like its tuned so Id say youre safe a/f wise

His WOT air/fuel is very safe. He has the ratio for a supercharged car, not N/A. To push it to the edge being N/A....it needs to be ~12.8ish

So what is the a/f on a bone stock 5.0 at wot?

pushing it to the limit with bumped timing tables is a mixture for a lunched #8 on these motors, 12.0-12.5 is much safer and gives a larger margin for error......IE bad gas
