air fuel ratio na and nitrous injected

[RedBullitt]

what would my best af ratio be right now running NA without the spray? i have my wideband in there as of tonight and i was just curious what i should run it at. how about with a 125 shot via a noszle direct port kit?

thanks

just trying not to break too much haha:SNSign:

Each car is different on what power they make at their air fuel ratio. Most N/a cars are between 12.8-13.5. My car is around 12.9

With Force Induction, it needs to be in the 12s or even lower but that should be done on a dyno so they can watch the air/fuel as you getting on it.

well with a wideband, if you keep it within stoich limits, you're good.

some widebands have programs that allow you to measure the most important thing in tuning: rate of acceleration. you can make sure the readings are always in the "green" area while maximizing how fast you accel from one rpm to another.

On most Stangs the best a/f ratio N/A is around 12.8, with nitrous you want it around 11.5-12, there is usually a spike up to 15 or so when the nitrous engages but then it will immediately come back down. The safest way is to get it dyno tuned for nitrous.

Mine stays around 13 N/A

keep it in the 11.5-12.0 range.

keep it in the 11.5-12.0 range.

I have the same setup as you. Noszle with 125 JETS. I only made 90hp and 90 tq with it tho. My a/f spikes to 14:1 thes comes back to 12:1 and settles out at 11.5:1 at 4900 to redline.

Mine never spiked with the NX dry kit and ran STUPID fat(around 10/10.5:1) until I got a tune in it. Ran around 11.5/12:1 NA before the tune as well.
