Knowones making any sense. This one guy on the forum with a mild street port sees 14.25 on the dyno. He has an N/A with a very mild street port. His afc numbers are - 18-20s. Hes been driving like this for awile. dont you guys know this??? Thats why I was asking people whats the highest you can go? I guess 14.25 is were its at if you have the same mods. Nothing beats expierience. Theory sucks.

1) I never said it's NOT possible to make power at other AFR's.  Sure, you can go leaner.  I bet the guy never bothered to try, or...
2) Wide-bands are not equal.  Unless we're talking about identical sensors mounted in identical spots, the numbers are going to be different - this is why I said to run a little richer and leaner than the base 12.5 - this eliminates deviations due to temps and sensor location.
Go talk to some V8 enthusiasts - they will back up those numbers.  Go read up on SAE books - you call a bunch of engineerings wasting their time with THEORIES?  Do you know how these people get their theories???  From experiements and hard data!
So what's YOUR experience???  Don't tell me you're regurgitating data from other people and have no experience of your own???
Oh, and before I forget...GO **** YOURSELF TOO.

it's not a matter of where the best power is... it's a matter of blowing the engine or not. leaner = more power = higher chance of blowing it up.
you just have to find the number between safty and max power. which reted says is 12.5-12.8...
you also have to make sure there is no cats between the engine and sensor if you are getting readings at the tips.

Well this guy im talking about that sees 14.25 af across the board makes 167-75 rwhp at the wheels. I think v8 specialist being pistons react differently to lean mixtures than rotories. I just wanted someone to agree that 14s are where the most power is at for N/As because thats where this forum member made the most power on the dyno and also because Im going to be tuning my S-AFC soon and wanted more opinions. Thnx anyways RETED but no thnx.

That's what people said when I searched for S-AFC settings.

But N/A's are almost never in danger of running lean, unlike TII's, where even minor mods can lead to fuel problems.
