what a/f ratio for boosted wot? what voltage on O2 is that?

Just wondering what to shoot for. 13:1 too lean? 12.5? this is for wot on a 9:1 c/r turbo GSR motor. will be street driven. And whatever ratio is best, what voltage would that approximate to on a 0-1V O2 sensor?
thanks,
Jared

Jared, not sure on voltage but usually on a boosted car, you want to see around 12.5, 13.0 is ok but might be getting a bit lean.

No, .5 is stoich. The O2 does not give anything out over 1v.

You probably want around .92 volts coming from the O2 for safe boosting. It is highly inaccurate though, but you know that.
