For you turbo'd guys out there what air/fuel ratio are you guys running at in open loop (WOT)? I want to know in actually A/F ratio or O2 sensor voltage. Thanks. If the A/F ratio you give is from a dyno pull (wide band O2) state that or if its from an after market guage state that. Thanks

I try to keep it at .88 or better on the talon.

bump 12.0 @ wot in 4th gear... aem uego, tapped right after the dp flex (i know i know)

like a 11.6-11.8...

Around 11.8-12.0 WOT in 4th gear. 93 octane on a BB U12 motor.

when i was boosted i ran 11.8 to 12 at wot

JWT reccomended that i stay 11.2-11.5 a/f

11.5-11.8 at wot--i'll see what this = to in o2 v in the a.m.

Holy 2002 batman.

Holy 2002 batman.

yeah, i don't like making new threads on technical stuff if there is one started... ;)

12,8-13 before fullboost
11-11,3 fuel pump 93
11,5-11,8 with water and 93
12-12,3 with alky
Cheers

that how your making that rr hold up.

11.8 - 12, 91 octane, 8.5 compression.

15 bitchez, take a walk on the wild side!

10.8 to 11.2

are the limits different for a true DET motor? I have seen higher a/f ratios on stock components... just wondering.

This is right plus 4gear tune with zero knock with load.Dont let the car knock and it will last long.

Better components means that they can take some more abuse ... so you can go a little futher on the tune.

Sub 10's in boost

EDIT: As per recommendation below:

91 Octane (highest you're getting at almost 3700ft above sea level) West Texas gas. Non ethanol blend.

JP pretty much has it right on for his AF's with fuels and other additives.... sub 10's is way to rich, you should be able to get it higher than that with no detonation issues. I look for around 11.6 -11.8 af @ WOT.
