What about using O2's with race gas?

[sc86gt]

I have built a 12.5 comp Windsor that will be used in a limited street, strip car. I know I will need to run race gas with this combo. Doesn't the race fuel kill the O2's? I've heard that using unleaded race fuel will solve the problem. So what's everyone do in this situation?

Tune with 02 then go closed loop.

Leaded race gas will indeed kill oxygen sensors, but not instantly - I'm not sure how long it takes, but it's long enough that a lot of racers find that the advantages of being able to run a wideband outweigh the trouble and expense of periodically changing out the sensors.
