been wondering if it was safe to use 110 oct. on track day ?
Is it safe for the 02? Will my a/f ratio change with it?
I know i should prob. tune a prom just for it but seems like an expensive trial -n- error period.

 

No lead race gas is fine. Leaded fuel will put a film on the O2 and render it useless. You could take out the O2 and plug the hole since what you're going to be doing (WOT) doesn't require an O2. One thing though, race gas is formulated for power but too high an octane might burn too slow and cut down on power. At worst it won't hurt your power curve but it may not help either so all you did was waste your money.
