what is minimum o2 #'s when spraying safe? topic says it all...I have blown head gasket so now i am being conservative. As of now I have 75 jet in n2o and 100hp jet in fuel (NX standard jets) just to be fat and safe. my o2's are .93-.95 with this setting. I know thats dead rich but i want to be VERY safe. plus I know the o2 aren't real accurate. I have no wide band available...YET

I haven't had any wideband dyno results yet so I err on the side of safety, I'm at 0.91 all motor and 0.95 or so with N2O. Once I get on the dyno, I can tell what's really going on.

Re: what is minimum o2 #'s when spraying safe? You want the car to run a little fatter with juice. I say low 9's preferably not less than high 8's. I had a friend running mid 8's in the o2 readings. He never hurt his motor until 1 day 1 of the injectors stayed shut. He did this for 2.5 years straight.
